NARRATIVE STATEMENT
0277509021
TITLE
Well 03 Tisline with the Mt. Olivet 3 MG Standpipe.
AREA
The aforementioned transmission line is to he located in Cedar River Park,
at the Maple Valley Highway intersection with Interstate N405, along Bronson
Way N. to N.E. 3rd Street and then East to the tank.
NEED FOR PROJECT
Well 00 was constructed in November 1967 and equipped in June 1968. The
well produces 3,500 GPM (5.04 MGD) , but has a trace of sand. Therefore,
it hoe never been put on lines Various alternatives have been investigateti
for the removal of this sand. It was decided to use our, existing 3 MG
ft. Olivet tank as a settling basin for wall N8 water.
The City has, when the opportunity has arisen, installed portions of this
proposed tieline. ' In Sheet 01, dated May 1969, a tie line between Well 08
and Wells 01 and N2 was constructed. A stub for the future Well 09 was
also provided for. Sheet 02 shows the location of Well #8 and future Well
09 and the connection to the existing main,. Sheet b: (W-373) shows a
portion of the main that was installed when the State Highway Department
improved and widened SR 169 (Maple Valley Highway) in December 1974.
Sheet 04 (W-429( shows a proposed portion to be installed between N. 3rd St.
and H-line of Interstate 4405, as wel: as another portion of the 24" installed
in conjunction with a new 16" water main in N. 3rd Et. Sheet 05 (W-265)ehows the route of the proposed 24' watermain to the Mt. Olivet standpipe,
COGRDINATION WITH OTHER WATER DISTRICTS
This proposed transmission main is not intended to provide service to outside
of the present City limits.

H. BASIS FOR ASSESSMENT SUPPORTING NEGATIVE DECLARATION ACCOMPANYING GRANT
APPLICATIONS
The impacts of this project are temporary in scope and all relate with
the construction period of the project.
No new businesses or human activity will result from construction of
this main, however, substantial savings will be made by utilizing Well
48 versus development of a new source. This project is a major action
with insignificant effects and warrants a declaration of negative impact.

A. PROPOSED ACTION
"he City of Renton Utilities Division iy requesting Referendum 27,
Bashington Futures funding for use in the construction of the Well
08 to Mt. Olivet Reservoir Transmission Main,
The Washington Department of Social a Health Services will review the
analysis of the environmental impact of this project.
The City of Renton, as primary applicant, will design, call for bids,
and build the proposed transmission main. The City has developed this
project in accordance with the 1965 Comprehenr'.v4 Water Plan.
B. ESISTINC CONDITIONS
Well 08 is part of the complex cf water supply wells in the Cedar River
and Liberty Park area. Wells 111, 1, 3, 8 and undeveloped d9 all lie in-
side tha two City parks. Mt. Olivet Reservoir lies approximately 3/4 of
a miie north at the intersection of Bronson Way N.E. and N.F.. 3rd Ave.
The areas between the reservoir and the park area is a heavily urbanized
zone of commercial uses and freeways.
well 88 is ; fully equipped wall complex, built in Ceder River Park in
1971. It has not been used because of recurring sand discharges.
C. E17VIPOrmEwAL IMPACT AND TNAVOILABI.E ADVERSE ENVIRONMENTA: EFFECTS
6
D. The proposed transmission main will have no permanent environmental
impact. There will be no secondary impacts associated with this pro-
ject. The transmission main will interconnect an existing water
source and reservoir, and will not interfere with public uses of the
City parks.
Some short term adverse effects may occur associated with the actual
construction. Erosion, dust and noise may create nuisances, however,
good construction practices will mitigate the major problems.
E. ALTERNATE TO THE PROPOSED ACTION
No action. The no action alternate would create serious problems in
the near future. Failure to construct the proposed trar.amissiOn main
would keep Well N8 off line and force the City to develop alternate
sources of water supply-
F. RELATIONSNIP SNORT-TERM USE AND LONG TEnM ENHANCEMENT OF THE ENVIRONMENT
6 AND IRREVERSIBLE OR IRRETRIEVABLE RESOURCES COMMITMENT
Tbc construct!- of the proposed transmission main will provide 6 lbng rpl
term tacility ing the Mt. Olivet tenk with the City water suppIirs,
This project will be irretrievable, howavor, substantial henofit will be U x
derived by construction of this project. " 1

SAND SETTLING IN TANK r
;F=g
r,
Assumptions.
Sand from Well No. 8 is very fine (40 micron dials. ) with a settling rate
of 0.21 cm/sec (0.007 ft/sec. ). This is minimum size described as sand in
literature.
y
Water bearing sand enters tank and is directed along wall opposite outlet.
i•_stgnce to outlet = loo'.
Probable vidt❑ of plug flow across tank = 50'.
Normal withdrawl rat, = 1,500 gp m = 3.4 ofs. v *•.•t'
If sand "plug" is kept to 10' depth, then time required to settle sand ."
10 ♦ 0.007 = 1428 seconds
Floes time across Lank
V= 34 = 0.007 ft/sec.
j00
Time _ 100 14,280 seconds.
0.007 f"yM
If sand short circuits to outlet along floor then raising the silt stop
to 5 ft. may keep sand out if upward velocity is less than 0.007 ft/sec.
At 3.4 efs thin requires a flow area of
3.4 a o.007 - 486 sq. ft. ,
Assuming a half cylinder ,f flow up around silt stop radius of cylinder
would be 16 ft.
SAND SETTLING IN BASIN
Assume 40 micron particles diam. M
Settling velocity - 0.007 ft/sec.
Bottom five feet of tank must be settled before effluent is put in
gravity line.
Gravity line can accept one c.f.s.
Then theoretical minimum required settling basin area
1 = 143 sq. ft.
0.007
Time to empty bottom 5 ft•
},000�Oo0 = 13.9 hours
7.5x8x 3600
For practical application the pond can be larger or the application rate
reduced.
At 0.5 cfs rate the bottom 5 ft. ciui be emptied in one day.

The tank cleanings would flow by gravity in this line to Cedar River. Inter-
mittently the line would be flushed under pre2sure to ensure full transports-
t'.on of the sand. This solution may require agency approvals for discharging
into the Cedar River (D.O.E. , Fisheries, etc. ) which should be in7eatigated.
If the material does tend to clog the Wipe then It will be necessary to
run the tank effluent through a settling basin prior to putting it into r�
the pipe. This can be done on the tank. site (see Attachment A for sample
calculations).
4. REQUIRED REVISIONS
A. Fcr Sand settling
1) New 12" inlet across t&:� from existing 16" inlet-outlet,
with removabl_ 900 bend for cleaning.
r,l
2) Five foot, extension on existing silt stop at 16" outlet.
A. For 'lank. Cleaning
1) Ne-, mavw.V aje it to new 12" inlet.
2) Connect, new taro inlet line to existing 8" drain line
at tank and to new catch basin.
3) Extend 12" drain line now running from Well N8 to the Cedar
River "..x :.Orly past future Well M9 to Sta. 10+90 (ref. W-429
sheet 3 of 6) and connect to 12" brancn line.
4) Se.tling basin, if necessary.

Sand bearing water would enter the Mt. Olivet tank through a new connectirn
In the southeasterly portion. The water will then move slowly through tba
tank to the existing 16" outlet feeding the Mt. Olivet Pump Stetion.
Ii the velocity is sufficiently slow the sand particles will t.,Itle to the
tank bottom prior to reaching the outlet. There are nurerous theoretical
and empirical designs for sedimentation and settling oasins. Since the
settling basin already exists we feel that if it reasonally appears that
the particles will settle out that the revisions be made to the tank and
the settling be tested. (See Attachment A for sample calculations.) ,
3. TANK CLEANING PROCEDURE
The Mt. nlivet Tank w4 L1 have to be chat down _nd cieaced o:' tLe settled
sand at regular intervals. The most efficient method cf sand removal
is difficult to predict and will be developed with experience. The '
possibilities are these:
1) The sand will be in a thin slurry that ran be e:c;ily �.
flushed down the existing drain without danger of
plugging the pipe.
2) The sand will be in a slvrry tnat isa be flushed or movea
with hoses but is thick enough to create a hazard of I .
settling out in the drain pipe.
3) The sand will oe a solid mass that will have to be
physically removed after the tank is empty.
i
Under the first condition sand removal is ac^_omplisied simply by draining the
tank with minor cleaning using hoses. his requ_res the new IP" inlet line
be connected to existing 8" drain line with proper valving.
Under the third condition the tank will have to be emptied and ti = sand
shoveled out. Assuming that the sand will not be transported as the tank
is emptied it will be feasible to use the 8" drain line. In order t-,
expedite removal a second manwey should be Installed adj+.cent to iht new inlet.
The second condition is the most difficult to handle. The material will be
too thick to put into a gravityline and too thin to shovel. The tank will
have to be cleared with hoses, probably not too difficult a job. If the
resulting sand-water m_x is thin enough then possibly it :an be transported
in a force main that can be intermittently flushed. This could be done
using the isolated 16" feeder main to south of Maple Vr.11ey highway and
extending a new 12" line from there southerly to the 12" drain line running
from Well 8 to the Cedar River.

Re: Letter Reports
Well 8 - Mt. Olivet Tank Project
rentlemel:
We submit this Report 1n conformance with our Agreement of 12 February 19T6.
1. STA7,%M'1T OF PROBLEM
The City of Renton constructed Well No. 8 to rugment its municipal water
supply, This well is located in Liberty Park, 15 feet east of SR 4o5
and 480' north of the Cedar River.
The well pumps fine sand excessively resulting in complaints from
users whenever it is put on the line. City Water Department operating
personnel indicate that this is typical of the wells in this area but
that the sanding condition has cleared up in a .,ut two years at the
other wells.
It is presumed therefore that this condition at Well No. 8 can be
rectified if the vE"_ can be used regularly for about two years. It ,
is also presumed t future Well No. 9, located about 430 feet north-
easterly of Well P., will have the same problem when it is developed
and put into service.
2. PROPOSED SOLUTION
The economically feasible method -f separating the sand is a settling
basin of some description. The C.ty's Utility Engineering Department
has proposed using the 3,000,000 gal. Mt. Olivet tank for that purpose.
Our examination of plans tar present facilities and for the W-429
project indicates that after W-429 is c -splete it will be feasible to
Isolate a feeder main between the Mt. Olivet tank and well No. 8 with
certain modifications to the tank. It will then be feasible to pump
from Well No. 8 (end 'Aell No. 9 in the future) without water entering
the distribution system.
