PUBLIC UTILITIES BOARD OF PUBLIC UTILITIES RIVERSIDE PUBLIC UTILITIES Board Memorandum DATE: DECEMBER 12, 2014 ITEM NO: 8 SUBJECT: FISCAL YEAR 2015 WELL REHABILITATION PROJECTS; PROFESSIONAL SERVICES AGREEMENT WITH GEOSCIENCE SUPPORT SERVICES, INC. FOR HYDROGEOLOGICAL CONSTRUCTION INSPECTION SERVICES ISSUES: The issues for Board of Public Utilities consideration are 1) approval of the capital expenditure in an estimated amount of $430,000 for two domestic well rehabilitation projects and 2) approval of a Professional Services Agreement with Geoscience Support Services, Inc. for hydrogeological construction inspection services. RECOMMENDATIONS: That the Board of Public Utilities: 1. Approve the capital expenditure in an estimated amount of $430,000 for the following two domestic well rehabilitation projects: a. $215,000 for Work Order No. 1508452, Van Buren 1 Well; and b. $215,000 for Work Order No. 1508453, Van Buren 2 Well; and 2. Approve a Professional Services Agreement with Geoscience Support Services Incorporated for hydrogeological construction inspection services for the Fiscal Year 2015 well rehabilitation projects. BACKGROUND: The Riverside Public Utilities Department (RPU) operates and maintains over 50 water wells throughout Riverside and San Bernardino to supply drinking water to the City of Riverside. Over time, the wells lose efficiency due to normal incrustation of minerals and metals in the walls of the well; and moving components in the pump assemblies deteriorate under normal wear and tear. As a result, water wells and pump assemblies require maintenance. On October 27, 2014, staff issued a Request for Proposals (RFP) to eight consulting firms to provide specialized professional hydrogeological support services for RPU's Fiscal Year 2015 Well Rehabilitation Program. Support services consisted of technical inspection, support for responding to questions from RPU staff and well rehabilitation contractors during the course of the project, technical direction during the work and review and analysis of data collected during well redevelopment and aquifer testing. In order to expedite work and minimize disruptions to well operations, staff obtained Board authorization on November 7, 2014, for three projects to rehabilitate the following water wells: Flume 4, Palmyrita and Garner 6. As part of this Board item, staff was authorized to utilize the Water Division Contractor's Panel to minimize disruptions to these water wells. In addition to these water wells, staff identified two water wells that need maintenance during the current Fiscal Year: Van Buren 1 and Van Buren 2. Staff has recently developed the scope of work for the Van Buren 1 and Van Buren 2 wells that are included in this authorization request. The scope of work for the Van Buren wells includes removal and inspection of the pumping equipment, video surveys, mechanical and chemical cleaning, as needed, and
