RECOMMENDED ACTION: Approve agreement regarding water service rights with Tidewater Utilities regarding service at the Wilmington College Property and authorize the City Manager and Finance Director to execute the agreement. BACKGROUND AND ANALYSIS The City of Dover has served potable water and provided fire protection service to the Wilmington College building located 3282 North DuPont Highway since March 2004. This building is located within Tidewater Utility’s Certificate of Public Convenience and Necessity (CPCN) territory. As such, City staff has been working with Tidewater to develop an equitable agreement which results in the City receiving the right to serve this customer and Tidewater relinquishing its rights under the current CPCN. The result of these negotiations is the Agreement Regarding Water Service Rights which is attached. Conditions of this agreement include the following: 1. Construction of a twelve-inch (12”) diameter water main along the northern property line of Wilmington College in an easterly direction to a proposed interconnection location with Tidewater Utilities. (This project was completed in FY 2007.) 2. Construction of valves, vault(s) and meter(s) at the proposed interconnection location. (This project is proposed for FY 2008. Work is to be completed by the Public Utilities Construction Division and expenses are to be equally shared between the City of Dover and Tidewater Utilities.)

Water Quality Update Utility Committee Presentation July 9, 2007 Public Utilities Department Water / Wastewater Utilities

Water Quality Overview Water Quality issues (i.e. brown water) began in 2002 following implementation of mandated chemical addition. As is the case with other systems nationwide, Dover’s water system was not designed for chemical addition. Complex system 3 aquifer sources Multiple entry points (1 Water Treatment Plant and 15 unmanned wells with treatment)

Water Quality Overview Black & Veatch has been utilized as a Water Quality Consultant to assist in analyzing the system and finding solutions to brown water issues. “Magic Pill” or “Textbook” solutions do not exist. It will take the dedication of staff time and financial resources to address all components relating to this problem.
