INTRODUCTION AS A. BACKGROUND INFORMATION 1. THE COORDINATED WATER SYSTEM PLANNING PROCESS In 1985, the Connecticut General Assembly passed Public Act No. 85- 535, " An Act Concerning a Connecticut Plan for Public Water Supply Coordination, " codified in Connecticut General Statutes as 25- 33c through 24- 33, initiating a procedure to coordinate the planning of public water supply systems. The objective of Public Act No. 85- 525 is the efficient and effective development of the state' s public water supply systems through a coordinated planning approach. Administration of the planning process is the responsibility of the Department of Health Services ( DOHS) in consultation with the Departments of Public Utility Control and Environmental Protection, and the Office of Policy and Management. In order to implement the coordinated planning process, a Water Utility Coordinating Committee ( WUCC) must be established in each of seven water supply management areas. Each WUCC will be comprised of representatives from area utilities and regional planning organizations. The WUCC in each region is responsible for preparing a required Areawide Supplement as part of the Coordinated a" Water System Plan. In addition to the Areawide Supplement, the large Mc utilities in each area or utilities required by the DOHS are to prepare individual water systems plans, ( large utilities in this context are public water systems serving 1, 000 people or more) . The South Central am Water Supply Management Area WUCC is made up of the members listed in Table 1- 1. c 2. MAJOR COMPONENTS OF THE COORDINATED WATER SYSTEM PLAN r The major components of the Coordinated Water System Plan are shown on Figure 1- 1. Within the Areawide Supplement, which is to be prepared by each WUCC, there are three parts: o Water Supply Assessment wr o Exclusive Service Area Boundaries Report AM o Integrated Report MA 1- 1 TABLE 1- 1 SOUTH CENTRAL WATER SUPPLY MANAGEMENT AREA WATER UTILITY COORDINATING COMMITTEE MEMBERS Aaron Manor Convalescent Home, Chester Idleview, MHP, Naugatuck Ansonia- Derby Water Company Krayeske Water Supply, Guilford a, Beechwood MHP, Killingworth Lake Grove at Durham Bernice' s Court, Guilford Lakeside Water Company, Guilford Beseck Lane Water Company Middlefield Leetes Island, Guilford Bittersweet Ridge, Middlefield Legend Hill Condos, Madison am Blue Train Acres, North Branford Lorraine Terrace, Middletown Bradley Home, Meriden Meadowbrook Rest Home, Essex Bridgeport Hydraulic Company Meriden Water Department Cedar Grove MHP, Clinton Metropolitan District Commission Central Naugatuck Valley COG Middletown Water Department Connecticut River Estuary RPA Midstate RPA Connecticut Valley Hospital , Middletown Mill Pond Elderly Housing, Durham Connecticut Water Company Mount St. John School , Deep River Country Manor Health Care Ctr. , Prospect New Lakeview Convalescent Home, Cheshire Crestview Condo Assoc. , Cheshire Nod Hill Apartments, Clinton Cromwell Fire District Water Dept.
