LYNN-Low water levels are forcing the Water and Sewer Commission to tap the Saugus River to supply reservoirs.Water Superintendent Rick Dawe blamed the low levels on a meager autumn rainfall and said a wet winter should push water levels to 80 percent or 90 percent by early spring.”We need a really good soaking to bring up the Ipswich River.”Dawe said water supply levels in local reservoirs are at 48 percent of capacity compared to an average 64 percent capacity for this time of year.”I’m concerned whenever it drops below 50 percent, but we’re not in panic mode,” he told Water and Sewer commissioners Monday.The Ipswich River is Lynn’s primary water source and Dawe said the river’s lower-than-normal water levels have forced Water and Sewer to draw from the Saugus.Commission members are not overly alarmed by the low levels, noting other parts of the country are experiencing water supply shortages. In other business this week, commissioners denied a request by a Pine Hill developer to have the commission share the cost of water flow improvements to his project.Thomas McGovern spent $49,400 to have a water pipe supplying a hydrant next to his Lois Lane development relined after fire inspectors said the aging pipe could not meet a 1,000-gallon per minute flow requirement.The Pine Hill native started building six single-family homes on Lois Lane off Linwood Street during the summer.McGovern said he wanted to split the bill with the commission, but an expense report reviewed Monday by the commission indicated he wanted Water and Sewer to cover $30,000 of the relining costs.He argued he paid the cost of repair work that the commission or another developer ultimately would have been required to do. But Commissioner Scott McPherson said McGovern should have discussed a payment arrangement with Water and Sewer before doing the work.”You made the decision on your own to take on the project and, by doing so, got the results you wanted,” McPherson said.He said developers of the Cannon Rock, Phaeton Rock and Ferris Road projects paid for water and sewer improvements benefiting their projects without asking the commission for a reimbursement. McGovern said those project upgrades differed from the pipe improvement he financed.Commissioners Wayne Lozzi and Frank Zipper favored reimbursing McGovern with Lozzi suggesting the commission cover the $10,607 expense involved in relining the hydrant pipe from Lois Lane to the end of Linwood Street.”If Mr. McGovern went away, this would have been on us,” Lozzi said.McPherson, Walter Proodian and William Trahant, Sr. voted to deny McGovern’s request.
