ACTION FORM
PROCEEDING: Utility Committee AGENDA ITEM NO.: 07-09-2007
DEPARTMENT OF ORIGIN: Public Utilities – Water DATE SUBMITTED: June 1, 2007
PREPARED BY: Ronald Lunt – Public Utilities Director
SUBJECT: Agreement with Tidewater Regarding Water Service Rights – Wilmington College
REFERENCE: N/A
RELATED PROJECT: Scarborough Road Interconnection (Tidewater Utilities)
APPROVALS: City Council
EXHIBITS: Agreement Regarding Water Service Rights
EXPENDITURE REQUIRED: N/A AMOUNT BUDGETED: N/A
FUNDING SOURCE (Dept./Page in CIP & Budget): N/A
TIMETABLE: City Manager to sign agreement following receipt of appropriate approvals.
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 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)
Página 12
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.
