DOLAN General Manager-Chief Engineer DATE December 17, 1980 SUBJECT TYPE OF ACTION AUTHORIZE $35,000 FOR INFilTRATION/INFLOW (1/1) MONITORING AND ANALYSIS SERVICES FOR AN 1/1 INVESTIGATION AND CORRECTION PROJECT IN ORINDA CAPITAL FUNDING AUTHORIZATION SUBMITTED BY James R. Coe INITIATING DEPT./DIV. erations ISSUE: Older sections of the weather flow last winter. In significant amounts of 1/1, a analysis project is proposed. Orinda area sustained up to ten times normal dry order to cost effectively locate and seal off detailed, accurate flow monitoring and computer BACKGROUND: American Digital Systems, Inc. (ADS) offers a rainfall and sewer flow monitoring and computer analysis program which is capable of locating and isolating sections of the sewer system which contribute up to 80% of the 1/1 from approximately only 20% of the sewers. We propose to contract with ADS to monitor about 70,000 1 ineal feet of sewers in the northwest protion of Orinda. The rainfall and sewer flow data gathered from approximately 20 flow measuring devices and one or two rain gauges in the area would allow the C.S.O. Department to systematically renovate the 14,000 lineal feet which would be the SOUTce of up to 80% of tb:eJ / I p'roM ern <for that area. The information and experience to be gained from this project would allow us to assess our repair and rehabilitation methods as they relate to 1/1 reduc- tion, to determine the cost effectiveness of an 1/1 reduction program, and to analyze the potential for a more comprehensive long range 1/1 program which may qualify for grant funding. The proposed authorized cost of $35,000 includes a 15% contingency over the ADS contract price which is intended to cover unfores€en field conditions and unpredictable weather. RECOMMENDATION: Authorize $35,000 for Infiltration/Inflow monitoring and analysis services by ADS for an 1/1 investigation and correction project in Orinda.

POSITION PAPER VIA: ROGER J. DOLAN General Manager-Chief Engineer DATE Dec. 1, 1 98 t) SUBJECT TYPE OF ACTION AUTHORIZATION OF $3,000 FOR THE REPAIR OF CONDUIT FROM THE DRAINBACK STRUCTURE TO MUX 82, LOCATED IN SUBSTATION Capital Expenditure 82 SUBMITTED BY D. G. Ni les INITIATING DEPT./DIV. Plant 0 erations De artment Issue: The treatment plant has experienced loss of power and control data from the drainback structure to Substation 82. Background: District forces have attempted to repair the broken conduit connecting Substation 82 with the drainback gate to no avail. It has been proven impossible to remove the existing cables from the conduit, indicating a probable rupture in the conduit itself. This may be due to settlement of the ground in this location. It is unknown at this time if the existing conduit can be replaced. A bid has been obtained for replacing the conduit in the amount of $3,000. Repair may consist of cable replacement only with repair of conduit and would appear to be in the approximate amount of $1,000. In either event the use of outside forces will be required for this task. Recommendation: Authorization of $3,000 for the repair of cable and conduit from the drainback structure to Substation 82.

DOLAN General Manager-Chief Engineer DATE December 3, 1980 SUBJECT TYPE OF ACTION AUTHORIZATION OF $4,000 FROM THE SEWER CONSTRUCTION FUND TO PLACE A THREE-INCH CAST-IRON DRAIN FROM MANHOLE NO.3 TO THE EXISTING SUMP IN THE DIVERSION STRUCTURE Capital Expenditure SUBMITTED BY D. G. Ni les INITIATING DEPT./DIV. Plant Operations Department Issue: The water infiltrates the high voltage electrical system at the Filter Plant and collects at manhole No.3. Background: During the past winter the Plant Operations Department encountered electrical difficulties in the high voltage conduit system at the Filter Plant. One of the major causes was due to deterioration of the system by excessive ground water infiltrating the conduits and draining to the lowest elevation at manhole No.3. This manhole fills up with three to four feet of water during storm flow. In the past a sump pump was utilized to periodically drain the system. It is possible to drain the manhole by placing a three-inch cast-iron drain from manhole No.3 to an existing sump located within the diversion structure; thus maintaining a drier system throughout the entire year. Estimates of t~e work cost have been obtained from local construction companies and appears to be in the amount of $4,000. Recommendation: Authorization of $4,000 for the construction of a three-inch cast- iron drain from manhole No.3 to the existing sump pump located in the diversion structure.

DOLAN General Manager-Chief Engineer DATE December 15, 1980 SUBJECT AUTHORIZATION FOR THE PRESIDENT OF THE BOARD TO EXECUTE AN AGREEMENT WITH WEGMAN/CAROLLO FOR PROFESSIONAL ENGINEERING SERVICES TYPE OF ACTION SUBMITTED BY INITIATING DEPT.!DIV. John Larson, Senior Engineer-Project Manage ent Special Projects Engineering Division BACKGROUND Central Contra Costa Sanitary District has accepted a $438, 431 Preconstruct ion Grant from the California State Solid Waste Management Board (CSS~1B) for Predesign Engineering on the District's Solid Waste to Energy Project. Proposals were received from nine engineering firms for this work and the four most qualified firms were in- terviewed by a selection committee. A joint venture between Leonard S. Wegman Company of New York and John Carollo Engineers of Walnut Creek was selected as the most qualified firm. A contract has been negotiated and approved by the California State Solid Water ~funagement Board. That contract is now complete and ready for execution. The Board of Directors authorized $516,000 from Sewer Construction Funds on June 19, 1980, to cover the cost of this work.

POSITION PAPER VIA: ROGER J. DOLAN General Manager-Chief Engineer DATE Dec. 9, 1980 SUBJECT AUTHORIZATION FOR t~NDLE WHIPPLE, SUPERVISING SURVEYOR, TO ATTEND THE WESTERN FEDERATION OF PROFESSIONAL LAND SURVEYORS CONFERENCE FEBRUARY 17-20, 1980 IN RENO, NEVADA AT AN ESTIMATED COST OF 580 TYPE OF ACTION BUDGET & FINANCE SUBMITTED BY Ja INITIATING DEPT./DIV. BACKGROUND: The surveying requirements for the District are varied and complex, requiring a broad range of surveying knowledge and experience. Our Survey Division is able to accomplish the diverse surveying tasks for the District with only one regular crew with a second crew being needed about 10% of the time. The current total cost to the District for fielding one survey crew is $766.40 per day. In order to utilize our surveyors as effectively as possible, the District Survey Division maintains a proficiency in, and an awareness of, best surveying practices. Participation in the annual State Land Surveyors Conferences and the annual American Congress on Surveying & Mapping conferences is part of our training program. This provides a continuing education process which is conveyed to all the District survey personnel. The California State Land Surveyors Conference for 1981 has been combined with the Western Federation of Professional Land Surveyors Conference. The total estimated cost for this conference is $580 and it provides over a dozen programs specifically applicable to District needs (see attachment). The 6-hour workshop at this conference on Adverse Possession and Prescriptive Rights is in answer to a request by our District Surveyor and requests from surveyors for other utilities. The District is interested in this subject because of the large number of undocumented easements in the Martinez and in the Los Lomitas area in Danville which need to be acquired. Funds have been included in the 1980-81 budget for this conference. RECOMMENDATION: Authorize payment of $75 for registration, plus actual expenses for meals, lodging, and transportation for attendance of Wendle Whipple, Supervising Surveyor, at the Western Federation of Professional Land Surveyors Conference in Reno, Nevada, February 17-20, 1980.
