H CITY ATTY CITY MGRi: RECOMMENDED ACTION: Adopt Resolution No. oo"J'7^ approving a consultant agreement with Wilson Engineering Incorporated for the design of the Agua Hedionda Sewage Pump Station, authorizing the sole-source purchase of pump station equipment, and appropriating funds for the project. ITEM EXPLANATION: Currently, sewage from the City of Vista and the northern sections of the City of Carlsbad flows through existing sewer lines to the south side of the Agua Hedionda Lagoon and pumped a short distance to the Encina Water Pollution Control Facility. The existing Agua Hedionda Sewage Pump Station is jointly owned by the Cities of Vista and Carlsbad, however, operated by Encina. This pump station presently has two (2) new 8,000 GPM (gallons per minute) and two (2) older 3,500 GPM pumps with an effective pumping capacity of 24.5 MGD (million gallons per day). Replacement of the two (2) older, smaller pumps would increase the stations capacity to 34.5 MGD and alleviate increasing maintenance frequency and costs. The present pump station capacity is expected to be exceeded in late 1988 with seasonal rain water infiltration adding to the sewage flows. On February 13, 1988, a sewage spill occurred at this pump station when increasing demand exceeded the capacity of the pumps. This situation is enhanced when one of the pumps removed from the system for maintenance purposes coincides with rainfall which increases the pump station's requirements. Upgrading the Agua Hedionda Sewage Pump Station will include two (2) new 8,000 GPM pumps, a new system control panel, 400,000 gallon overflow basin, new standby generators, and a mechanical bar screen designed to remove materials which would otherwise clog the pumps. The concrete walls of the pump station will be enlarged to accommodate the bar screen and the variable frequency motor drives for the new pumps. These improvements will expand the station's capacity to meet forecasted demand, reduce maintenance cost, and minimize future sewage spills, a. For easy maintenance and interchangeability of parts, the two (2) replacement pumps are recommended to be ordered identical to the existing 8,000 GPM pumps. The City Council is requested to authorize a sole-source prepurchase of the two (2) new pumps from the same manufacturer of the existing equipment. Staff believes there to be significant economies and maintenance flexibility to specifying identical equipment within the pump station. The pumps require several months lead time for manufacture and S a. O delivery. With the City Council's approval, the City will 8 Page 2 of Agenda Bill No. prepurchase the two (2) pump assemblies at the quoted price of $60,210 with delivery anticipated this coming fall prior to construction of the pump station's improvements. Five (5) proposals from qualified engineering consultants were reviewed by staff from the Cities of Vista and Carlsbad as well as Encina. Wilson Engineering Incorporated was identified as the firm considered the most qualified for this project. The design proposal includes complete system design and specification of all pump station improvements as well as inspection and project management services during bidding and construction for a lump sum cost of $109,100. Staff recommends approval of the attached consultant agreement. FISCAL IMPACT; The Agua Hedionda Sewage Pump Station project is identified in the current Capital Improvement Budget to be upgraded in 1992- 1997. The recently completed City-wide Sewage Master Plan Study lists the replacement of the Agua Hedionda Sewage Pump Station equipment as a priority for the continued efficiency of the City's sewage transfer system. Staff recommends proceeding at this time to upgrade the Agua Hedionda Sewage Pump Station in an effort to minimize increasing maintenance costs and reduce the potential for sewage spills into the Agua Hedionda Lagoon. The City Council has previously appropriated a total of $2,520,000 in the 1985-1986 and 1986-87 Capital Improvement Program budgets for the Vista/ Carlsbad Sewer Interceptor replacement project. Construction of this project is not anticipated to take place until approximately 1990 and is not considered as high a priority as the Agua Hedionda Sewage Pump Station upgrade. The City Council is, therefore, requested to approve a funds transfer in the amount of $200,000 from the Vista/Carlsbad Interceptor project account No. 512-820-1850-3182 to the Agua Hedionda Sewage Pump Station project account No. 512- 820-1850-3303 to enable proceeding with the design at this time. A summary of the estimated design costs for the Agua Hedionda Sewage Pump Station Project is as follows: Project design, inspection, and construction administration $109,100 Prepurchase of two (2) pumps 62,210 Staff time and contingencies 30.690 $200,000 Approximately one-half of these costs are reimbursable from the City of Vista as joint owner of the Agua Hedionda Sewage Pump Station. The precise ratio of ownership, and therefore reimbursement, will be determined by Wilson Engineering's study of sewage flows through the station. The City Council will be Page 3 of Agenda Bill No. requested to appropriate funds for construction of the pump station upgrade in the 1988-89 CIP budget. EXHIBITS : 1. Location Map. 2.

Wilson, President Title APPROVED AS TO FORM: ATTESTED: Assistant City Attorney City Clerk EXHIBIT "A" SCOPE OF SERVICES Project Description The design of the Vista/Carlsbad Interceptor and the Agua Hedionda Lift Station Upgrade involves two interrelated projects. The design and the construction of the improvements to the Agua Hedionda Lift Station need to be fast-tracked so that construction on these improvements is completed by December, 1988. The station is nearing capacity and the operation of the station would be more reliable, especially during the winter months, if the additional capacity was available. The Vista/Carlsbad Interceptor Reaches VC5 through VC10 and Reach VC10A are not yet at their design capacity. However, they are nearing design capacity and agreements between Vista and Carlsbad call for the design to be completed so the improvements can be constructed quickly when needed. This project is also being designed so that portions can be installed concurrent with downtown Carlsbad street improvements. Improvements to the Agua Hedionda Lift Station Task 1 - Coordinate and track the prepurchase of the two new pumps. Task 2 - Conduct field investigation to as-built present mechanical, electrical and control equipment. Under this task we will also verify the adequacy of the present electrical service and work with the Encina Water Pollution Control Facility staff to determine proper replacement equipment for the existing level control system. Prepare biddable plans and specifications for the Agua Hedionda Lift Station. These plans shall be separate from the Interceptor work. Designs shall include the following elements. A.

May 12, 1988 102-001/24 City of Carlsbad 2075 Las Palmas Drive Carlsbad, CA 92009 Attention: Gary Kellison Subject: Prepurchase Pumps for Agua Hedionda Pump Station We recommend that Fairbanks Morse Pumps, identical to those now operating at Agua Hedionda Pump Station, be prepurchased for the upcoming upgrading project. During the last upgrade of the Agua Hedionda Pump Station in 1986, we evaluated whether or not to purchase additional Fairbanks Morse pumps or open the bidding up to Allis Chalmers and allow them to also bid on the project. We obtained two firm price quotes for these pumps from the manufacturers and compared the two bids. Although the Allis Chalmers pump was lower in capital cost, we felt that the benefits which the Encina Water Pollution Control Facility would derive from matching existing equipment far outweighed the difference in cost of the two pumps. In fact, we paid additional money during that upgrade so that Fairbanks Morse would use their old casting for the pumps so that all parts would be interchangeable on the new and old pumps. We felt this led to lower maintenance costs and greater reliability at the station. The reason for this reduction in costs follows. 1. Interchangeability of parts on the pump. 2. Spare part stocking for only one brand of pump. 3. Personnel familiarity with the pump. The prices which we obtained for the two pumps for this upgrade are actually lower per pump than the pumps purchased in 1986. This is due to the fact that we are buying two 2185 FARADAY AVENUE, SUITE 14O CARLSBAD. CALIFORNIA 92OO8 (619) 438-4422 pumps instead of one. We feel that the price for the pumps is fair and recommend that two Fairbanks Morse pumps be prepurchased for the Agua Hedionda Pump Station. Please call if you have additional concerns or questions regarding this matter. Wilson Engineering Kevin E. Schmidt KES:jaa
