Plan Pare Corporation EXECUTIVE SUMMARY This Water Supply System Management Plan (WSSMP) has been prepared as required under Rhode Island General Laws 46-15.3, as amended and titled “The Water Supply System Management Planning Act” (Act). The legislative authority to effectuate the goals and policies of this Act has been conferred to the Rhode Island Water Resources Board (RIWRB). To this end, the RIWRB has promulgated the Rules and Regulations for Water Supply System Management Planning (“Rules”), last revised in October 2002, as amended to implement the provisions of the Act. The Smithfield Water Supply Board (SWSB), as a water purveyor supplying over 50 million gallons (MG) of water per year, is responsible for updating its WSSMP every 5 years. This document is the 2015 Update of the WSSMP for the SWSB. The WSSMP has been prepared to be consistent with the goals of the Rules as well as the strategies and goals articulated in the RIWRB’s 2012 Strategic Plan and the RIWRB’s Water Use and Efficiency Rule for Major Water Suppliers. It is also consistent with the goals of State Guide Plan Element No. 721 – RI Water 2030 and the goals stipulated in the Comprehensive Plans for the Towns of Smithfield and North Providence. Introduction The SWSB’s primary objective is to operate a water system for the benefit of, and to meet the legitimate needs of, the customers in its service area. In accordance with that objective, the SWSB’s specific goals are to: 1. Promote the efficient use of water through: - conservation and efficient operation of the system in accordance with industry and State standards; and - effective metering and public information programs that encourage water conservation. 2. Comply with all applicable laws and regulations. 3. Protect the integrity of its existing source of supply connection to the Providence Water Supply Board (Providence Water). 4. Cooperate with the overall goals of the Town of Smithfield and the Town of North Providence as outlined in their respective Comprehensive Plans. 5. Provide for service to all locations within its service area. 6. Conform to the overall goals for water suppliers established in State Guide Plan Element No. 721 – Rhode Island Water 2030. Pare Corporation - i - Background The Town of Smithfield, through the SWSB, owns and operates a public water distribution system in a non-exclusive territory, serving portions of the Towns of Smithfield and North Providence. The SWSB was developed from a subsequent Water Supply Commission enacted by the Town of Smithfield. This Commission was authorized and established by Chapter 1676, 1930 Public Laws of Rhode Island with the purpose of developing “an accurate and comprehensive study of the water supply of the Town of Smithfield”. Today, the Town Council acts as the Board of Water Commissioners for the SWSB. Water system management and day-to-day operations are the responsibility of the Water Commissioner and SWSB staff. Mr. Charles Walsh is the Acting Water Commissioner, as well as Deputy Director of Public Works for the Town of Smithfield. The SWSB has two other full time employees, both identified as “Field Observers”. The SWSB operates out of the Smithfield DPW facility at the following location: 3 Spragueville Road Smithfield, Rhode Island 02917 Telephone Number: 401-233-1034 The SWSB’s mailing address is at the Smithfield Town Hall, as follows: 64 Farnum Pike
