Olivet steel reservoir, The star a question "a CH2H servicua during construction. This estimate assumed that apy,-ximately one week would bo spent on each of the tanks for actual installation of the anodes in the tanks. The conduit and cable to the rectifier I could probably be installed during this time. It was our intention to make ra,-ts after this portion of the work we completed to correctly Size the re.tlfier for the particular installation. The rvc Cifier would then be ordered and installed at a later date. By doing the work in this manuar we would spend extra time on the job but the system would be much more satisfactory than if the rectifier vat sited from insufticlaut information. The estimate I submitted to you includes this work in sorvlc,:s during rorsttuction. The items should be listed as follows: Mt.

As shove in our letter of 2 Octo` r 197U th.s is an estimate of rhr time required, ll..s amount should not be exceeded and could be considerably less depending upon the rate at which the system can be installed. We will make every effort to do the work in the shortest possible time and will be in constant con- tact with your office so that you can be assured that t.Lme is not being wasted. If you have any queetlons regarding this breakdown of time to be spent an this project, please let me know. Very truly yours, C01-NELL, ROWLA.W, HAYES d MERRYFIELD G. W.

Olivet steel reservoir. Authorization for this work was per the City of Renton Purchase Order Nos. 15064 and 15065 dated 7 January 1971. -1_ ' CHAPTER II SUMMARY OF INSTALLATIONS ' -esign of both cathodic protection systems was completed in December of 1970 as C112M/HILL Project No. 56367.1. Author- ization for thib project was per letter from Mr. Jack Wilson, City Engineer, City of Renton, dated 6 November 1970. tOesign :irawings, CH2M/HILL No. 6367.1 sheets 1 through A, are ' included in Appendix 1 of this report. These drawings have been revised to stow "as-built" installation of the cathodic protection systems. Complete bills of materials were prepared for each installa- tion as part of the original design. Copies of these mate- rial lists are included with this report in Appendix 2. ' 7pon approval of design drawings and receipt of authorization ' to proceed with installation of the cathodic protection sYstems, quotations for the materials required were requested M from prominent suppliers of cathodic protection materials. The materials were ordered on the basis of the lowest quota- tion submitted. Installation of anodes and associated equipment was completed 1 in both the Mt. Olivet reservoir and the Highlands elevated tank in August of 1971. Picture Nos. 1 through 5 show some ' of the installation in progress at the Mt. Olivet reservoir.

This information was needed to 1 determine correct size of rectifiers to operate the cathodic protection systems. For these tests sturaae zatteries were 1 used to supply d-c power to the anodes. The resulting poten- tial changes in the steel structures were measured with reference 1 to the zinc electrode installed in each reservoir. Utilizing the data secured from this testing rectifier 1 capacities were chosen to supply adequate cathodic protection for both facilities. In determining the rectifier capacities, iconsideration was given to future changes in current requirement: for cathodic protection brought about by factors such as de- terioration of internal coatings, possible changes in water composition, etc. These data and calculations are included 1 on Data Sheet No$. l., 2, and 3 in Appendix 1 of this report. Automatially controlled cathodic protection rectifiers were ordered for both systems. The automatic-type units were specified so that constant and correct structure-to-electrolyte potentials will. he maintained automatically in each reservoir. The automatic units will compensate for any changes in eater conductivity which may occur with seasonal changes or changes in the source of water. In addition, the automatic units will compensate for changes in water level within the reservoir. Thus, the necessity for periodically measuring the potential of the structures and manually adiustina the rectifiers to ' compensate for such changes is greatly reduced. ' The rectifier for the Highlands elevated tank was received and installed in October of 1971. This unit was energized a � a- 1 1 and initially adjusted on 29 October 1971. Data Sheet No. 4 shows the initial readings and the output at which the rectifier was se::. i The rectifier for. tc_ Nt. Olivet reservoir was received and 1 installe9 in November of 1971. This unit was energized and initially adjusted on 8 November 1971.

G 1 1 ' 1 i 1 1 1 CHAPTER III TESTING AND FINAL ADJUSTMENT 1 The cathodic protection systems were allowed to stabilize for 1 approximately 60 days. During the week of 3 January 1972, both systems were checked and final testing and adj-,sting was completed. 1 The Mt. Olivet reservoir system was checked on 3 January 1972. 1 Data Sheet No. 6 shows the rectifier output and the structure- to-zinc reference electrode potential reading as found. The rectifier voltage and current had decreased considerably, in- dicating excellent polarizetion of the system. The struoture- 1 to-reference electrode potential as initially set on 8 Nov- ember 1971 had been maintained perfectly by the automatic unit. 1 In order to further determine the effectiveness of the auto- matic rectifier to maintain a constant potential in the res- ervoir, recording equipment was set up to nonitor and record 1 any changes in the potentia- of the reservoir and any corres- ponding changes in current output of the rectifier ..✓er a 24- 1 hour period. Very little change in potential or current was recorded, indicating very little change in the water level in the reservoir. 1 On 6 January 1972, a vertical potential profile of the res- ervoir wall was made. This was done by lowering a copper/ 1 1 -12- copper-sulphate (Cn/CuSO4) reference electrode into the res- ervoir and measuring the potential of the reservoir wall at 2-foot intervals with the rc tier turnee off and on. The ' results of this testing, which ar•_ recorded on Data Sheer No. 7, show excellent polarization potentials along the ' vertical face of the reservoir wall with no extremely high or low potential areas. A rectifier meter check was made checking the efficiency of ' the rectifier voltmeter and ammeter against a standard meter. The results of this tdstirg, as recorded on Data Sheet No. 8, show the rectifier meters to read somewhat low but to be 1 accurate for all practical purposes. A circuit resistance check was also run; the results of which can be found on Data Sheet No. 9. This rectifier was left at an output of 7.0 volts and 4.5 ampe�ese of current resulting in a structure- to-reference electrode potential of -0.05 volts. This poten- tial is equivalent to a structure-to-copper/copper-sulphate (Cu/CuSO4) reference electrode potential of -1.15 volts. NOTE: The structure-to-Cu/CuS)4 potential reading is referred to since the copper/copper-sulphate reference electrrde is the standard used in corrosion work. lWhen a structure-tr-Cu/CUSO4 ' potential of -0.85 volts is achieved through the application of cathodic prctection, the structure is considered to be ' "cathodically protected" with corrosion mitigated.) Since a copper/copper-sulphate electrode is not feasible for con- tinued use in a water storace facility, the zinc reference electrode is generally ased. The open circuit potential of zinc with respect to a copper/copper-sulphate electrode is generally -1.11 volts. Utilizing this potential a structure- to-zinc electrode potential can be easily converted to an ' -13- equivalent structure-to-cu/cuso4 electrode potentia: by algebraically adding to two, as shown in the following example: Zinc- to-Cu/CuSO4 electrode reading = -1.10 volts Structure-to-zinc electrode reading = -0_05 volts Add algebraically - ' Equivalent structure-to-Cu/CuSO4 = electrode reading -1.15 volts tOn 6 January 1972, tte Highlands elevated tank system was checked. Data Sheet No. 10 shows the rectifier output and the ' structure-to-zinc reference electrode potential reading as found. Here also, the rectifier voltage and current had de- creased considerably since initially energizing the system indicating excellent polarization of this system. The structure- to-reference electrode potential as initially set on 29 October 1971 had been maintained within 10 millivolts by the automatic unit. Recording equipment was also installed at this location over ' a 24-hour period to monitor and record changes in the potential of the tank and corresponding cF:anges in current output of the ' rectifier. Portions of recording charts showing some of the major changes during this period are included as Figures 1 ' through 4 in Appendix 4. As can be seen, the structure-to- reference electrode potential as previously set was maintained by the rectifier auto.uatically increasing or cecreasinq current ' output to compensate for changes in the water level of the tank. ' A rectifies meter check and a circuit resistance check were run at this installation on 7 January 1972. The rectifier meters read slightly high, as recorded on Data Sheet No. 11 -14- ' in Appendix 3 but can be considered accurate for all practical Purposes. The results of the circuit resistance check are recorded on Data Sheet No. 12. This rectifier was left at an ' output of 7.4 volts and 3.0 amperes of current resulting in a structure-to-reference electrode potential of -0.50 volts. ' This potential is equal to a structure-to-Cu/CuSO4 potential of -1.60 volts. 1 1 1 ' CHAPTER IV RECOMMENAATION*S CONCERNING OPERATION of SYSTEMS The cathodic protection systems, as covered in this report, will provide efficient operation with very little maintenance required. However, it is essential that certain routine checks be made on a regular basis to insure long and efficient service. ' In addition, comprehensive records should be kept of all data taker.. ' It is recommended that the following checks be made at the ' frequency noted: ' 1. Monthly Rectifier Check. Each rectifier should be checked at least once a rtwnth, basically to ascertain that the}, are operating. The rectifiers should be examined visually to see ' that no damage has occurred to the case or any of the compon- ents. If a rectifier is found off, the reason for it being off should be determined and the rectifier should be turned back on as soon as possible. ' The output of each rectifier should be checked by reading the t voltmeter ar9 the ammeter. These readings, as well as any unusual circumstaneas involved if a rectifier is found off, should be recorded ci a card or sheet designed for t:,is nur- tpose. A typical record sheet is shown in Appendix < on Figure S. -16- ' The potential of the structure to the reference electrode should also be checked at each location each month. This can be accomplished by connecting the test leads from a voltmeter to the terminals provided on the front panel of the rectifiers. The positive lead of the voltmeter should be connected to the terminal marked "refererce electrode," and the negative lead of the voltmeter should be connected to the terminal ' marked "structure. " The resulting voltmeter reading will be a negative or "minus" voltage reading. tAfter a structure-to-reference electrode reading is taken with the rectifier on, the rectifier should be turned off and a ' similar reading taken. It nay be necessary to either change polarity on the voltmeter being used or switch the test leads ' on the rectifier panel terminals, since the potential with the rectifier off may result in a positive or "plus" reading. ' Both the rect'fier "on" and "off" potential readings should be ' recorded on the record sheet. The rectifiers should be maintained at the following structure- to-reference electrode potentials for a least the first year of operation: Mt. Olivet Reservoir -0.05 volts Highlands Elevated Tank -0.50 volts ' Current and voltage output of the rectifiers may fluctuate somewhat in order tc maintain the above potentials, and such fluctuations will not be cause for alarm. However, if drastic ' changes in rectifier output with resulting changes in structure- to-reference electrode potentials are experienced, further 17- checking may be necessary. Information entitled "Trouble- Shooting Rectifier Failures" is provided at the end of this chapter to assist City of Renton maintenance personnel in maintaining the rectifiers in operating condition. After taying the above readings, the rectifier should again be checked to ascertain that it is operating and is not left off. 2. Annual Survey of Systems. Each cathodic protection syst^m ' should be completely checked and adjusted, as necessary, at least once a year. ' During this survey rectifier meters should be checked and cali- brated as necessarv, and the circuit resistance of each system ' should be checked. Efficiency of the rectifiers can be deter- mined and necessary maintenance, such as replacement of diodes, etc. , to provide the most economical operation of the systems can be advised. In addition, a complete vertical potential profile should be taken of each reservoir wall at various locations, such as recorded on Data Sheet No. 7 in Appendix 3. This tasting will determine that anodes are discharging current properly and that all areas of the reservoirs are being ade- quately protected. CH2M/HILL corrosion personnel will be available to p1tovide this ' annual service if the City of Renton so desires. ' "iR- ' TROUBLE-SHOOTING RECTIFIER FAILURES Cathodic protection rectifiers are relatively simple and nor- mally require very little maintenance. If a problem does exist, it can usually be located by the following procedures: A. No Voltage or Current Output 1. Check a-c line voltage with a-c voltmeter. a. No a-c voltage. Check power source for Clown ' fuses, etc. Call power company if necessary. b. A-c voltage satisfactory (110 volts) . Check circuit breaker in entrance switch and in rectifier. ' r,. Both circuit breakers operating - check a-c ' output at terminals 1 and 2 (marked AC INPUT) on the black 6-terranal connector block. This ' a-c voltage should be slightly higher than the normal d-c output voltage of the rectifier. If there is no a-c voltage at this point, then ' the problem is in the transformer. If, however there is a-c voltage at this point and no d-e output voltage, then the rectifier assembly, or one of the connections, is at fault. Bad con- nections can usually be repaired by the person making the checks. I£ the transformer or recti- fier is damaged, a new component must be in- stalled. ' -19- B. Rectifier Output voltage Normal - No Output Current 1. Install resistor across output terminals. Amster fshould operate in accordance with ohm's law, i.e. : Rectifier Current - Rectifier Volta e Resistance Between ':'erminals ' 2. If current flows in Step 1, then check cables to structures or anodes. If cables are broker., t-:ey must be excavated and repaired. 3. If no current in Step 1, then meter defective, Door connections, or rectifier stack open-circuited. ' 4. If rectifier stack defective, replace with new unit. ' C. Rectifier Output Current Normal - No Output Voltage 1. Check voltmeter by attaching portable voltmeter with correct range across output terminals of rectifiers. 2. if portable voltmeter reads correctly in Step 1, then repair connections or replace meter in rectifier. • _20- B_ i . . 1 1 i 1 1 1 1 1 1 1 1 1 1 1 1 1 APPENDIX 1 1 DRAWINGS i N YJT lY ) NO1NlM V •. 1 : - Y - I � CRCF.F INlp Z.y�O<M4 T/ON ; 1 I = CRItL ANO rAP Nat{s FpR I%i° LONDNIr AS :MOWN `,j .PIpU/RLDl.

Olsen, Utility Engineer City of Renton 200 Mill Avenue South Renton, WA 98)55 Subect: Renton Medical Center Dear Mr Olsen: The Renton Group Health Medical Center urgently needs additional parking spaces in order to serve safely and efficiently the increasing number of subscribers in the Renton Community. If we were to obtain additional leased space for staff at the Mount Olivett Tower parking lot, our problem would be reduced considerably in scope by removing more staff from our lot on the medical center property. I'd appreciate you and your staff reviewing this request. : would be most happy to work with you to insure the proposed development would fall completely within City guidelines. We concurrently are conducting an in-depth study to mavinize the parking capability of our existing lot; however, the unusual site plus the drastic yrade changes limn most possibilities of adequate change. Offsite parking of staff would affect the greatest change. Thanks so much for your attention and cooperation.
