Wellesley Water Division

The following report is a requirement of the Federal Safe Drinking Water Act (SDWA). The SDWA requires that most community water utilities furnish to their customers an annual record on water quality and tap water-related issues. That report covers the season 2017 but also includes relevant data from other years. The analytical results provided in our report are conducted by way of independent certified laboratories. The following annual report will help the Wellesley DPW to see consumers about the sources and quality of their drinking water, approximately the decision-making process the fact that affects their drinking water. General population participation opportunities are available at the monthly Board of People Works meetings. For further data, contact Water Superintendent, Bill Shaughnessy P. E., by 781-235-7600 x 3350 and located at 20 Comunitario Way The MWRA is mostly a regional utility that uses surface water supplies during central Massachusetts at the Quabbin and Wachusett Reservoirs as well as Ware River. The MWRA water quality report certainly is the final page of this doc and is available on their website. 12 months 2017 results of all diagnosed contaminants in MWRA liquid are included in this insert. The moment reviewing the water quality info, it is important to keep in mind that a mixing up of the MWRA and some of our local waters will cause right after in the two glasses of water to moderate. The diversity of individuals water supply sources provides for mobility so that a reliable supply of mineral water is available to serve the needs you have. In addition to these active resource sources, the Wellesley standard water distribution system is also connected with four other criminal court water suppliers for communal emergency preparedness. These some other water suppliers happen to be Natick, Needham, Weston, and Wellesley College. The Ma Department of Environmental Coverage completed its Source Liquid Assessment Program (SWAP) Article for all of Wellesley’s local hydrant sources. Copies of this survey are now available upon the need of the Wellesley Water Split (see ADDITIONAL INFORMATION). The report is intended to be used as being a planning tool to support native and state efforts to increase water supply protection. As for best suburban locations, the susceptibility of Wellesley’s groundwater record zones (i. e. Region II’s) is high. The assessment helps focus coverage efforts on appropriate very best management practices and moving water source protection measures. MINERAL WATER DISTRIBUTION SYSTEM There are roughly 140 miles of avenue mains that distribute each of our water throughout the town. That distribution system also includes two large storage facilities that contain a capacity of virtually six million gallons. Due to the configuration of the distribution Droit and the storage facilities, normal water from any given supply supplier has the capability of reaching any sort of point within the town. STANDARD WATER TREATMENT SYSTEM Wellesley runs three water treatment comforts. The primary purpose of these establishments is to provide the regulatory permitted treatment technique (TT) to get corrosion control under the A safe drinking water supply Act’s Lead and Real estate agent Rule. These facilities provide you with the same treatment processes to all or any of our wells. Figure #1 illustrates the treatment processes found at these facilities. The good water is oxidized and its particular pH is adjusted previous to filtration. The filter practice removes the naturally occurring in terms of iron and manganese minerals inside raw water. The filter units consist of anthracite, oriental sand and garnet mud. After filtration, the water chute through a tray aerator, which removes naturally occurring carbon dioxide in the water. This aeration method removes the acidity through the water. The water is fluoridated and finally, the water is disinfected with hypochlorite and held in large holding containers before being pumped in the distribution system. SYSTEM CHANGES Our water system is often inspected by the Massachusetts Team of Environmental Protection (MassDEP). MassDEP inspects our system due to the technical, financial, and bureaucratic capacity to provide safe drinking water for your requirements. Our water system is inspected in 2016 and improvements were made to our program based on that inspection. To make certain we provide the highest quality of liquid available, your water method is operated by a Massachusetts professional operator who oversees the master plan operations of our system. Together with our ongoing commitment to you personally, in 2017 we crafted the following improvements to our program: • The filter advertising of the 9 feet height filters at the Longfellow WTP was replaced to restore the filters to their original filtration capacity. • The Wellesley Avenue gravel pack bore holes were cleaned by chemical p treatment and one perfectly was provided an additional cure by Aqua Freed cure to provide a more effective restoration of this well. The well high heel platform sandals were cleaned, inspected and reinserted and one good pump and motor failed inspection and was swapped out. • The Wellesley Path TFC well screen and well casing failed plus the 24-inch diameter good was rescreened with a great 18 inch well tv screen and brought back into assistance. • The chlorine place at the Wellesley Avenue WTP was refurbished and innovative chemical feed pumps are installed. • The MWRA 48 inch transmission mineral water main that supplies Wellesley and Needham was removed from the line for repair from leaks. An above perspective 24-inch bypass main is installed to provide temporary standard water to meet.
