Metro construction of the May Creek Interceptor (as requested by the City of Renton) is subject to Metro's sewer extension guide- lines, which require that extensions of the metropolitan system be financially feasible. This means that the number of customers immediately tributary to the new facility would have to be ade- quate to amortize the capital cost of that facility. ?n 1979 the City of Renton informed Metro that there were 2018 existing con- nections that would be tributary to the May Creek Interceptor. These customers would be served, however, via the City's Honey Creek and Kennydale Interceptors. T.te May Creek Interceptor, therefore, series no purpose unless the Honey Creek and Kennydale interceptors are constructed. When and if the City of Renton demonstrates ai intention to construct the Honey Creek and Kenny- dale intercepters, Metro will proceed with the financial feasi- bility analysis for construction of the May Creek Interceptor. If the number of _ustomers that would be irtmodia1 —y tributary to the May Creek Interceptor is determined to be inadequate to amor- tize the capital cost of that requested facility, the City would then have to guarantee whatever additional revenues would be nec- essary to insure that the financial feasibility requirement is met. Although a demonstration of the City's intention to construct the Honey Creel: and Kennydale interceptors is certainly essential in order for Metro to construct the May Creek interceptor, that demon- station of intention alone will not cause Metro to construct the May Creek Interceptor. Hopefully this clarifies Metro policy as Mr. Richerd Houghton July 30, 1981 Page Two it relates to the proposed May Creek Interceptor. Please contact me if you have further questions. I would be happy to meet with you or others to further explain the foregoing. Ve ly yours, Rob r� Hirsch Local Agency Lffairs RNH:yw I 1 1 ��r kE . -. t. tra z PUBLIC WORKS DEPARTMENT x WARREN C.

Shinpoch, Mayor and Members of the Menton City Council Municipal Building Rnton, MA 96055 $!jbject: Sunset Lift Station Dear Mayor Shinpoch and Council Members: Attached to this memorandum is reports, previous memorandums and data relative to the Sunset Lift Station and the proposed Kennydale and Honey Creek sewer interceptors. Based upon the attached analysis and the present circumstances, it is recommended as follows: 1 . That connections to the systems served by the Sunset Lift Station be prohibited by moratorium following the connection of the following properties which are in permit application process: a. 75-unit apartment complex on the east side of N.F. 12th Street and Union Ave. N.E. b. 16-unit duplex complex southerly of the shopping center at Sunset and Du�ail Ave. N.E. c. Neighborhood shopping center at N.E. corner of Union and Sunset. d. Small L. I.C. proposed by Shannon O'Neil to serve the northeast corner of Sunset snd Duvall Ave. N.E. The total connections of the above properties w' 1I be less than the calcuiated 361 units which would still be allowed under the attached analysis. This moratorium could be immediately effective subject to the exempt on of those properties. 2. That the CIV, proceed and authorize: a revenue bond !ssue In the amount of $2,000,000 for the purpose of providing the financing necessary to con- struct the Noney Creek and Kennydale Interceptors.. A complete analysis of the debt servlce requirements for this bond issue will be coordinated with the completion of our Water 6 Sewer Rate Study estimated to be com- pleted on December 15th. We feel that there Is good probability that this bond !;sue can be serviced without an Increase In the sewer rates and If such an increase Is required, it would be only a small Increase Mayor L City Council -2- November 24, 198U for a short period of time. 3. Based upon the bond Issue in 2. above, request Metro to proceed with the constructiu-, of the May Creek interceptor. In uur 1981 budyut, we have requested funds for a complete analysis and comprehensive plan of our sewer system. This will include an inflow infiltration analysis along with a recommended cost-effective solution to the inflow and infiltration problem. Very truly yours, i Warren C. Gonnason, P.E.

Pop Attachment • `p f _.; 4w u�....a w.._a.. _.u.... . .•..:...:4_3..a of ..z. . f N✓FY Since 1976 when the Sunset Lift Station was last analyzed, 141 single family resi- dences and 12.26 acres of commercial development have been connected to the system upstream of the lift station. These connections represent an addition of approximately 100,000 gallons of effluent per day. The average pumping times for the summer months corroborates these calculated volumes. To date the lift station has had the capacity to handle the normal flows generated during the summer months except when there is an unseasonally heavy rainfall. The major problem with the station is two-fold. The first and least troublesome problem to date has been conversion of the downstream system from a gravity system to a pressure system. As can be seen on Exhibit "A" when one pump from the Honey Creek and Sunset Lift Stations are on simultaneously a major portion of the down- stream system is in a state of transition from a gravity system to a pressure system. However, when the two pumps from the Sunset Station are on the transition has taken place and the majority et the downstream system has been pressurized. The latter was the case for at least sixty days over the past two years. The second problem results from inflow and 'infiltration during the winter months. Infiltration is ground water that enters the sewer system through joints, cracks iL! , 1%, r agi�efectl,.ns in *he system. Whereas inflow is surface water that enters the sys• t .. through storm dreins, ;roof gains, manhole covers and other sources. This inflow and infiltration irmaets i„e pump station in direct proportion to the intensity and duration of a storm. During the past two years the system has over- flowed on four different occasions, 15 days of which were not attributable co a malfunction in the system. In addition there were 44 days during the past two years in which 3n overflow was a real possibility. At the time an overflow occurs the sewage backs up in the system until it comes out a manhole in Union Ave, N.E. north of Sunset Blvd. N.E. and empties into Honey Creek, lloney Creek in turn empties into May Creek which empties into Lake Washington on the south side of Barbee Mill. The Sunset Lift Station rehabilitation in 1974 consisted of installing larger pumps. This type of rehabilitation is no longer possible due to she physical constraints of the existing station. in order to increase the pumping .aracity of the station, it will be necessary to rebuild the entire station. However, if larger pumps were installed the downstream system would be further pressurized and it is unknown at this time how great the potential is for damage to downstream properties. At the time of an overflow the volume of effluent being discharged into lioney Creel is unknown. However, using design criteria and our actual pumping times this volume can be computed to be approximately 250,000 gpd based upon a 10 year storm. The longest duration of an overlfow condition was for eleven days in Uecembur 1979. To have prevented this spill , substantial storage would have been required over and above what was stored in the upstream system. The elimination of the inflow and infiltration according to the report prepared by Moore, Wallace and Kennedy in May 1975 would not be cost effective. According to the report it would cost $25,315 to eliminate 425,000 gpd. The cost of these improvements adjusted to 1981 dollars at an annual inflation rate of 10% would be $45,000. The elimination of this extrenious water still would not eliminate the potential for an overflow only reduce the number of incidents and their duration. Page 2 On site storage of effluent during overflow conditions for individuals wishing to develop has been suggested as a way to allow development to continue. This practice would not compound the problem nor would it correct the problem. It would just be a method of allowing development to continue on a temporary basis until the May Creek and Honey Creek trunk lines were installed. In light of the above facts, it is projected that there will be between 12 and 20 overflow days for the 1980-81 rainy season. However, using the design criteria for new construction, exclusive of the peaking factor, the pump station has the capability of handling 361 additional single family residents with a total pumping capacity of 768,000 gal/day and a basin of 330 acres. The additional capacity is computed as follows: Units Persons/ Unit Gal/Person Total Gallons Single Family 597 3.5 60 125,370 Multi Family 432 2.5 60 64,800 Schools 3 2657.0 15 39,855 Inflow and Infiltration 330 ac 1100 _13,000 593,025 768,000 - 593,000 = 175,000 17S,000 = 3.5(60) + 1100 x Assuming 4 units/AC 4 x = 361 single family units 1 Us = 449 Gal/Min EXHIBIT A DESIGNED CONDITIONS EXISTING CONDITIONS -- PIPE DESIGNED I PUMPHONEY CREEK LOCATION SIZE FLOW (Cfs) 1 PUMP SUNSET 2 PUMPS SUNSET NE 7th St. - between Sunset 8" 4. 13 (3.25) (3.51 ) Blvd. NE & Aberdeen Ave. NE 8" 3.27 (3.25) +0.02 3.51 -0.24 Aberdeen Ave. NE - between 8" 1 .58 3.18 -1 .60 3.44 -1 .86 NE ith St. and NE 8th St. 10" 3. 11 (3.18) +0.07 3.44 -0.33 10" 6.33 (3.18) (3.44) 10" 5.17 (3.18) (3.44) • NE 9ti Place 10" 3.30 (3.18) +0. 12 3.44 -0. 14 10" 4.72 (3.18) (3.44) 10" 4.73 (3.18) (3.44) i0" 2.17 3.12 -0.95 3.38 -1.21 10" 2.14 3.12 -0.98 3.38 -1 .24 Easemen, - between NE 9th Place 10" 2.25 3.12 -0.87 3.38 -1 .13 and Ferniale Circle 10" 1 .75 3.12 -0.87 3.38 -1. 13 Ferndale Circle 10" 1 .64 3. 12 -1.48 3.38 -1. 74 west end to NE 9th Street NE 9th St. bet.t-�n Ferndale 8" 1 .65 3.12 -1.47 3.38 -1 .73 Circle and Harrington Ave. NE 8" 3.81 (3.12) (3.38) 8" 2.96 3.03 -0.07 3.29 -0.33 Harrington Ave. NE between 8" 1.82 (2.74) +0.08 3.0 -0.18 NE 9th St. aid Sunset Blvd. NE 8" 1 .08 2.74 -1 .66 3.0 -1 .92 . 8" 1.10 2.74 -1 .64 3.0 -1.90 Sunset Blvd. V between 8" 2. 13 (1.68) (1.94) Harrington Ave. NE !4 NE loth St. 8" 2.55 (1.68) (1 .94) Sunset Blvd. NE oetween 8" 1 .62 1 .68 -0.06 1 .94 -0.32 NE loth St. & NE 12th St. 8" 1. 71 (1 .68) +0.03 1.94 -0.23 e" 1 .27 1 .63 -0.36 1 .89 -0.62 8" 1 .30 1 .63 -0.33 1 .89 -0.59 Sunset Blvd. between NE 12th St. 8" 1 .91 (1 .54) (1 .8 ) and Newport Ave. NE 8" 2.09 (1.54) (1 .8 ) W. 1 .91 (1 .54) (1 .8 } 8" 1. 21 1.28 -0.07 1. 54 -0.33 EXHIBIT "B" SUNSET LIFT STATION Average Daily Flows (GPM) (One Day Peak Fiows) (GPM) (Day of Overflow) JA`a FEB MAR JUNE JULY AUG SEPT 1975 336,500 302,625 265,700 165,984 130,470 146,145 186,015 (576,000) (468,500) (377.000) (155,000) (171,000) (497,500) 1976 354,400 311,950 296,695 200,383 191,245 203,145 215,450 (454,000) (386,000) (346,500) (208,500) (232,000) (238,000) 1977 273,5" 263,232 318,742 295,050 242,581 279,417 (311,O0t .

Shinpoch, Mayor and Members of the Renton City Council Municipal Building Renton, MA 98055 Subject: Sunset Lift Station Dear Mayor Shinpoch and Council Members: Attached to this memorandum is reports, previous memorandums and data relative to the Sunset Lift, Station and the proposed Kennydale and Money Creek sewer interceptors. Based upon the attached analysis and the present circur -__.,ces, it is recommended as follows: i . Tiiat connections to the systems served by the Sunset Lift Station be prohibited by moratorium following the connection of the following properties which are in permit application process: a• 75-unit apartment complex on the east side of N.E. 12th Street SnQ Union Ave. N.E. r' b. 16- nit duplex complex southerly of the shopping center at �Sun,et and Duvall Ave. N.E. c. Neighborhood shopping center at N.E. corner of Union and Sunset. d. Small L. I.D. proposed by Shannon O'Neil to serve the northeast corner of Sunset and Duvall Ave. N.E. The total connections of the above properties will be less than the calculated 361 units which would still be allowed under the attached analysis. This moratorium could be immediately effective subject to the exemption of those properties. 2. That the City proceed and authorize a revenua bond issue in the amount of $2,000.000 for the purpose of providing the financing necessary to con- struct the Honey Creek and Kennydale interceptors. A complete analysis of the debt service requirements for this bond issue will be coordinated .with the completion of our Water 6 Sewer Rate Study estimated to be com- pleted on December 15th. We feel that there is good probabilitf tha, this bond issue can be serviced without an increase in the sewer rates and if such an Increase is required, it would be only a small increase Mayor L City Council .2- November 24, 1980 for a short period of time. 3. Based upon the bond issue in 2. above, request Metro to proceed with the construction of the May Creek interceptor. In our 1981 budget, we have requested funds for a complete analysis and comprehensive plan of our sewer system. This will include an inflow infiltration analysis along with a recomended cost-effective so!ution to the Inflow and infiltration probleft. Very truly yours, Warren C.

SHINPO(H. MAYOR 09o94 )ED (E�'0 SEP MEMORANDUM TO: 'larren Gonnason OATS: November 10, 1980 Don Miller red Kaufman Dick Houghton FROM: Mayor Shinpoch My thanks for participating in our discussion regarding capacity of our sewer system in the Honey Creek area. I expect some initial data by November 26th stating whether or not we should seek an imirediate building moratorium from the Council . In the interim, it's my understanding that all prospective developers in this basin will he put on hold with the onus on them to propose an acceptable solution. If cur statistical information does not warrant imposing a moratorium, I would hope we'd have a phase-in schedule for future development and a definite cut-off number beyond which the City wil ' issue no further permits. Barbara Y. Shinpoch, Mayor BYi:hh i i 1 SUNSf l L I I I SIA1101 IMPACT ou DOWN ;TREAM SYSTEM the basic information on the Sunset anti Muney Creek Lift Stations IS attached as Exhibits I and 11 . The Sunset Station pumps at the rate of 500 gpm .ond the Honey Creek Station has a pumpinq capacity of 100 gpm. The Honey Creek Station is insignificant with regard to the total volume pumped but due to the rate at which it pumps its impact is significant. With both stations pumping into the down stream system at the same time the flow developed is 1.34 cfs. yd 3 This flow exceeds the down stream capacity of five sections of 8" pipe without any additional flows. These five sections amount to 1436 ). f. of pipe and are C.- identified on Exhibit Ill . Exhibit III is a breakdown of the down stream system from manhole to manhole with the length, slope, and site ofr'pipe=indicated. From this Information an*-MaR— D723 the capacity and velo- city of Nte�tew^i-n each section as determined. These were then compared to the flows that are actually generated by the development- der that empt into the down stream system. The actual flows were calculated by using accited criteria which are outlined in Exhibit IV. The flow generated was broken into fourteen segments as outlined in Exhibit V for the purpose of determining at what point and at what volume flowsenters the main system. The residential units and commercial acreage in each segment was obtained by actual field surveys. Comparing the design flow against the calculated flow reveals th.. in the down stream system there are a number of section of pipe that are undersized. There are four sections where existing flow exceeds design flow by 1 .0 cfs. There are six sections of pipe in which design and existing flows are within 0. 1 cfs of each other. There are nine other sections which fall in between these two ranges. The total amount of exiting 8 and 10 inch pipe that would have to be replaced in order to upgrade the existing system so that the design flow exceeds the present flow Is 5,122 I .f. This amount of pipe represents 66% of the entire down stream system ( that is either at or above design capacity. Due to the +l -1 the Sunset Lift Station it is common for the y vi01°" t '?4otr to bock up into the manholes. This condition converts the flow in the down ,. stream p*pe from gravity to pressure. this has been verified an many occasions but is not documented. Thi-s--typwr-ffirnrrsa^ YfatsiT'3ny' sower- and i+tdicatls-that -Ow flow, R PM• Since I was not possible to obtain actual flow readings for peak condition In the down stream system some discussion of the design criteria and their accuracy would be appropriate. y.tt- davkloP ♦ logical and justifiable approach to pcavdwtg th_a�,?ah�,•� down stream system is being overtaxed by flogs from the May Creek llasitf wo appro- aches w ie taken. The first involved determining the number.)a d types of facilities and area draining into the down stream system including the areas that are served by the Sunset and Honeydew Lift Station. The second approach Involved determining flows contributed to the down stream system by the Sunset Lift Station through the use of daily recordtkept on pump operating times. The records for the Pave 2 lift station were compiled for 3 munths during both the dry and rainy seasons aoA averaged on a monthly basis for 1975 and 1976• This information is compiled nd tabulated in Exhibit V1 which also shows peak flows for a single day in each month. i The flows in Exhibit VI correspond fairly close to the flow developed by calcula- tions based on actual house count vf r Are s A(0 . A(2) and A W in Exhibit V. 1 Since these three areas lift station and the flow generated by pumping is constant . no peaking factor was used. f During dry weather the pumps operate on the average for about 465 minutes per day L with a total flow of about 200.000 gpd• According to JW# calculations the developed area that d�r��a�,�n.��s,,,to 3 e, lif) station generates a flow of abou�00,000 gpd. This symetry'Sa e- ennd during the rainy season. "MEOW be calculations are based on average flows for inflow and infiltration while the actual pumping time reflects the duration and intensity of each individual storm. Yheu averegad-tie reiumrthat is atttraftYptm�ett rs-ti'erY"t'k to the developed-by-calculation. As was shown earlier the down stream system is being overtaxed by the sewage being pumped from the May Creek basin. This �,I�G�Jhastegy,Irred that City forces per- form daily mainteran a check dry the +rw to oca'te any areasin which the flow is being restricted°' f'f�ssextrao dinary to routine is required to prevent damage and massive claims against the City by down stream property owner's due to sewage backup. This program has been successful in that property damage has been held Oemin to a minimum. There )have been only three incidents In 1972 of damage in which the City had to reimburse property owners. After this incident te vve in his lin o that it can beeclosededuri grper odsr in stalled preventsa/yrfutue s future damage to his property. Based upon accepted criteria or actual measurement it is felt that satisfactory documentation has been presented to justify the statements that the flow from the Sunset Lift Station is overtaxing the down stream system into which i't"dralns. If funding were approved for the May Creek Interceptor the need for the Sunset and Honeydew Lift Station would be eliminated since the sewerage that these stations handle could flow by gravity to the May Creek Interceptor. A*- Wit out funding both stations will require major overhauls within the next two 114 years and the present down stream system will have to be improved In order to elim- inate the constant threat of damage to property owners and the costly and constant maintenance of the existing down stream system. a 4 1 - E xnittlt 1 J4I IARY ',t WE Ilr ' TAT ION NAME: "upset I LOCATION: Sunset Blvd. N.E. and Union Avenue TYPE: Vertical pumps dry well Two wet wells MODEL: Smith and Loveless 48-3.

DELAURENTI S ptember 7 , IU a MAYOR REGEN 3 LSEP3 19i9Honorable Charles Delaurenti, MayorMembers of the City Council nL;.1JN OFFICE Dear Mayor Delaurenti and Council Mc,,je'r Moore, Wallace and Kennedy, Inc. hav prepa*vd cc t. estimatep for the installation of the Honeydew and Kennedelt tr�:nk seer lines. These estimates have been reviewed and a sumr2a'y hreakdo% , is attached and marked "Exhibit A". The total construction cast f.1t cuese lines is approximately $1,650,000 including a 10% irj%atlon factor from the present until the proposed commencement of construction in approxi- mately one veer. It is proposed that the City instali the lines shaded yellow as shown on the attached map marked "Exhibit B" and finance the installation with the sale of revenue bonds in the amount of $1,650,n00. Earlier attempts at installing the Kennydale lines by means of an L.Z.D. were unsuccessful: however, there was and has been a lot of interest in their installation. With the installation of the Honeydew trunk line the City will realize substantial savings through the elimination if the Sunset and Honeydew pump stations. Also, with the elimination of the flows from the two pump stations into the Highlands trunk line the cost of rehabilitating both the pump stations and the downstream lines will be greatly reduced. The Municipality of Metropolitan Seattle will be installing that portion of the Mav Creek Interceptor as shown shaded blue on Exhibit B". Their schedule is such that they should commence construction during ttte second euarter of 1930 and complete it by the end of tle year. The City would then connect to this line at points A & C with its construction. Although the City is financing the initial installation, 0ese costs will be recollected by means of a latecomer agreement to the City as the pro- perties in the drainage basin develop and connect to the system, The latecomer agreement would be based upon the actual cost Of coc.struc- tion divided by the net area to be served. Based upon current estimates the latecomers would be $0.030 per sq. ft. Also those properties which Page 2 are adjacent to a trunk line will be charged for one-half the cost of I nstalling an eight inch line across its frontage. Currently there are a number of properties which are developing in the Kennydale and Honeydew basins which are pumping their sewage into another basin. It is proposed that a project account be set up so that properties that develop prior to the installation of the trunk lines can be assessed their fair share of the installation cost based upon $0.03 per sq. ft. At present there are six developments that fall into this category and their total charges would amount to approximately $49,000.00. In conclusion, it is requested that authorization be granted to establish a project fund for the two trunk lines to be financed by revenue bonds and proceed with the design and construction of the Kennydale and Honev- dew trunk lines so as to be able to connect to the May Creek trunk line as shown on "Exhibit B".

Enclosed please find a complete and current evaluation of the Down Stream System which substantiates our claim that the Sunset Lift Station is over- loading the system into which it is discharged. Actual flow measurements would have been the more desirable method of substantiating the overloading of the down stream system; however, this would have required waiting until the rainy season so that the flows could reflect normal peaks due to inflow and infiltration. Since toffs was impractical , fiow,, wete calculated using criteria which is consistent with our application and accepted standards. 1 hope this information satisf„Ltorily answers your questions in sufficient detail to alleviate any doubts regarding the lift stations impact un the down stream system. For your information, please find attached a letter from the King County Department of Public Health concerning septic tank problem in the May Creek drainage basin. If I can be of further assistance or you require any additional information please advise. Very truly yours, Donald G.

( hear Sir: The area of the May Creek Pamir west of 139th Ave. S.F. contains • variety of soils ranging from Shalear Muck to the Rverett Series Pravel, i Predominant however, are the Alderwood and Kitsap soils, neither of t which are entirely adeouate for on-site sewage disposal systems. 1 Although the area .s not completely or intensely developed our records indicate 174 malfuntioning drainfields with sewage discha, ,ing onto the surface of the ground. I Our records, as far as researched, also indicate several disapprovals of site applications submitted for the purpose of developing individual lots. The number of disaporovals, however, is no real indication of suitability for constructior of houses with septic tarn systems, since persons performing the soil test generally advise their clients of the lack of required soil depth or iradenuate percolation rates and the applications do not reach this office. Tt is doubtful that any extensive development could occur or septic tanks in the subject area, although some individual lots might be found suitable.

Very truly yours, �y William P. Llenin�q, R.S. Supervising Sanitarian Environmental Health Services Southeast District Health Center WFLAg SUNStI LIIT SIAT1ON IMPACT 014 DOWN :TREAM SVSU M The basic infur.nation on the Sunset and Honey Creek Lift Stations is attached as Cxhibits I and II . The Sunset Station pump; at the rate of 500 gpm and the Honey Creek Station has a pumping capacity of 100 gpm. The Honey Creek Station is insignificant with regard to the total volume pumped but due to the rate at which it pumps its impact is significant . With both stations pumping into the down stream system at the same time the flow developed is 1 .34 cfs. This flow exceeds the down stream capacity of five sections of 8" pipe without any additional flows. These five sections amount to 1436 I . f. of pipe and are identified on Exhibit 111 . Exhibit III is a breakdown of the down stream system from manhole to manhole with the length, slope, and site of pipe Indicated. From this Information and Man- nings coefficient of roughness for concrete pipe of 0.013 the capacity ant velo- city of the flow in each section wus determined. These maximum allowable flows were then compared to the flows that are actually generated by the development that empties into the down stream system. The actual flows were calculated by using accepted criteria which are outlined in Exhibit IV. The flow generated was broken into fourteen segments as outlined in Exhibit V for the purpose of determining at what point and at what volume flow enters the main system. The residential units and commercial acreage in each segment was obtained by actual field surveys. Comparing the design flow against the caicula:ed flow reveals that in the down stream system there are a number of section of pipe that are undersized. There are four sections where existing flow exceeds design flow by 1 .0 cfs. There are six sections of pipe in which design and existing flows are within 0. ) cfs of each other. There are nine other sections which fall in between these two ranges. The total amount of existing 8 and 10 inch pipe that would have to be replaced in order to upgrade the existing system so that the design flow exceeds the present flow is 5, 122 I . f. This amount of pipe represents 66% of the entire down stream system that is either at or above design capacity. Due to the excess flow generated by the Sunset Lift Station it is common for the flow to back up into the manholes. This condition converts the flow in the down stream pipe from gravity to pressure. This has been verified on many occasions but is not documented. This type flow is an undesirable condition in any sewer and indicates that the flow exceeds the capacity of the pipe. Since it was not possible to obtain actual flow readings for peak condition in the down stream system some discussion of the design criteria and their accuracy would be appropriate. In an iz tempt to develop a logical and justifiable approach to proving that the down stream system is being overtaxed by flows from the May Creek Basin two appro- aches were taken. The first involved determining the number and types of facilities and area involved draining into the down stream system including the areas that are served by the Sunset and Honeydew Lift Station. The second approach involved determining flows contributed to the down stream system by the Sunset Lift Station through the use of daily record kept on pump operating time. The records for the r � F awe i It station „ere compiled for 3 months during both the dry and rainy seas( n, and averaged on a monthly basis f',r 1975 and 1976. This information is compiled and tabulated in Exhibit vl which also shows peak flows for a single day in each month. The flows in Exhibit VI correspond fairly close to the flaw developed by calcula- tions based on actual house count for Areas A(1) , A(2) and A(3) in Exhibit V. Since these three areas empty into the wet wells for the lift station and the Clow generated by pumping is constant , no peaking factor was used. During dry weather the pumps operate on the average for about 465 minutes per day with a total flow of about 200,000 gpd. According to our calculations the developed area that drains to the lift station generates a flow of about 200,000 gpd. This symetr) can also be found during the rainy season. However , the calculations are based on average flows for inflow and Infiltration while the actual pumping time reflects the duration and intensity of each individual storm. When averaged the volume that is actually pumped is very close to the f'gure developed by calculation. As was shown earlier the down stream system is being overtaxed by the sewage being pump-d from the May Creek basin. This problem has required that City forces per- form daily maintenance checks on the tine to locate any area in which the flow is being restricted. This extraordinary maintenance routine is required to prevent damage and massive claims against the City by down stream property owner's due to sewage backup. This program has bean successful in that property damage has been held down to a minimum. There have been only three incidents in 1972 of damage in which the City had to reimburse property owners. After this incident one of the property owners installed a gate valve in his sewer Iine so that it can be closed during periods of peak flow in order to prevent any future damage to his property. Based upon accepted criteria or actual measurenMnt it is felt that satisfactory 0 umentation has been presented to justify the statements that the flow from the S - ,et Lift Station is overtaxing the down stream system into which is drains. If funding were approved for the May Creek Interceptor the need for the Sunset and Honeydew Lift Station would be eliminated since the sewerage that these stations handle could flow by gravity to the May Creek Interceptor. As a matter of fact the May Creek Interceptor will pass right next to the Honey Creek Lift Station. Without funding both stations will require major overhauls within the next two years and the present down stream system will have to be improved in order to elim- inate the constant threat of damage to property owners and the costly and constant maintenance of the existing down stream system.

Using the above i As shown on Plate 1, the quantity of sewage pumped at the Honey Creek Creek Pump Stati, Lift Station does not vary with season, but remains relatively constant at an average daily flow of approximately 2,500 galions per 17 homes x day. 59.5 people As shown on Plate 2, the quantity of sewage pumped at the Sunset Lift Station does vary significantly with season. While the average Jaily summer `low is approximately 100,000 gpd, the maximum observed Referring to Plu daily wet weather flow is shown to be approximately 535,000 gpd. averages about flow does not va Rased an this information, additional flow monitoring at selected flows, this area manholes in the Sunset Lift Station contributory area was conducted. The three "key" manholes selected for monitoring are shown on Map 3 and are labeled Manholes A, B, and C. An automatic flow depth measuring and recording device was installed in each of these "key" manholes on a one-week rotating schedule. Simultaneously, a portable "event recorder" was installed at the Sunset lift Station.
