SAUGUS – The Department of Public Works has not only helped the town go a little greener, it has garnered some green for the town as well.John Faragi and Vincent Imperial recently wrapped up a plumbing project where the men swapped out old toilets for newer environmentally friendly low-flow sets. The completion of the project netted the town a $3,000 check from the Massachusetts Water Resource Authority and will go far in conserving water for the town.DPW Superintendent Joseph Attubato said he was contacted earlier this year about the project that only 45 communities qualified for.”The MWRA knows us because of the no-interest loan we take every year,” he said. “Which is a good thing. This is a really big help to us.”According to the MWRA it received a $40,000 grant from the Department of Environmental Protection to conduct a low-flow toilet retrofit rebate project. Communities were encouraged to purchase and install toilets that were 1.6 gallons per flush or less or low flow valves for their municipal buildings. The idea was to replace the less efficient toilets and for each toilet it replaced the community would receive a $100 rebate.Attubato said the newer buildings and those that were part of the capital campaign like the DPW, the library and Public Safety and Town Hall, which had been renovated, already had the low flow toilets. That left all six schools and a handful of other municipal buildings that needed to be retrofitted.We did 56 altogether, but only 30 qualified for the rebate,” Faragi said.Faragi said he handled much of the paperwork on the project.”While I actually did the work,” Imperial added quickly.While swapping out toilets might sound simple the job was anything but. Imperial said it took them several months to complete and entailed climbing into ceilings looking for water valves and sometimes slithering into some very tight spaces.”It wasn’t easy at all,” he said.But it was worth it, Attubato said. The toilets make the town a greener place and put $3,000 in the coffers.Attubato said while the MWRA has been good to the town concerning such programs, he is only sorry there is just one more year left to take advantage of the no-interest water line loan.Attubato has been using the loan for several years to complete work on the town’s woefully outdated water system.”The town doesn’t put anything toward it so this is the only money we have,” he said.But it is nowhere near done and Attubato is concerned that once the loan runs out the water lines will fall into disrepair once again.”We have 125 miles of water lines,” he said. “We have maybe half done. The big one I’d like to see done is Route 1 but I do not know when that will happen.”
