' DEPARTMENT OF WATER MANAGEMENT Memorandum No. 2009-06 April 1, 2009 TO: Honorable Mayor Carrigan and City Co cil FROM: Ryan P. McCrady, City Manager � John A. Smith, Assistant City Manager for Public Services Keith D. Alexander, Director of Water Management i�� iv� SUBJECT: South Water Treatment Plant Flouride Tank Storage Facility Improvements SUMMARY RECOMMENDATION: Council approve the attached resolution awarding a Technical Services Agreement for South Water Treatment Plant Flouride Tank Storage Facility Improvements to Strand Associates, Inc. for an amount not to exceed $25,800. BACKGROUND: Per State regulation, flouride is added to the City's drinking water supply to reduce dental decay. The 6,000 gallon storage tank that contains the flouride (in solution as hydrofluorosilicic acid) has developed a small leak at the bottom and needs to be replaced. The current flouride storage system is located in the basement of the South Water Treatment Plant (SWTP) and even when not leaking emits slightly corrosive fumes which settle on and slowly deteriorate numerous pieces of nearby equipment, pumps, piping, walls, floors, ceilings and doors. At this time the fumes and leak do not present a hazardous work environment, however, the leak needs to be promptly repaired before it potentially gets larger and creates a hazardous condition. Since the tank is in the basement, the old tank would have to be cut into pieces to be removed, and a new tank would have to be custom built in place. Since this process is rather expensive, and the fact that the fumes will not be eliminated, a new flouride storage system located outside of the SWTP is recommended. Strand Associates, Inc. has been providing the City with high quality engineering services at reasonable costs for the past several years. Since it is anticipated that their services will continue to be needed in the future, a Master Agreement with Strand is proposed. This project will be the first one assigned to the Master Agreement. The City has a similar agreement with Black & Veatch Corporation. The agreements do not bind the City to exclusive use of either firm for professional services, nor do they contain retainage fees. Instead, the agreements merely expedite the formal paperwork process for future projects involving these two firms.
