LYNN-Water and Sewer Commission Director Daniel O’Neill insists the Walden Street dam is structurally sound and said a state safety non-compliance order slapped on it is confined to spillway repairs.”It’s sturdy as the Hoover Dam as far as I’m concerned. It’s not going anywhere,” O’Neill said.The state order added the 1,000-foot by 29-foot dam to a long list of dams determined to be in need of repair in the wake of a May 2006 storm that caused extensive flooding and collapsed dams.Five Saugus homeowners have filed a lawsuit claiming water released through the dam spillway during the storm flooded their property.Commission attorney Samuel Vitale said the commission will comply with the state order giving Water and Sewer six months to prepare a dam repair plan.”We will conduct an inspection and formulate a plan to do remedial work,” Vitale said.Water and Sewer has two other major projects on the drawing board. It is accepting bids beginning Jan. 22 from contractors interested in completing combined storm sewer work.The commission will spend $1.6 million to complete sewer connections at Sanderson Avenue and Bowler Street and finish work on a backup system at Groveland Street.The work will ensure only storm water is discharged out of the pipe at Kings Beach and reduce the amount of storm water flowing with sewage into the Commercial Street sewage treatment plant.Creating a separate storm and sewage pipe network is crucial to helping the Commission meet a 2009 federal deadline for reducing sewage discharges into the ocean.The project involves drain and culvert construction designed to complete combined sewer work undertaken by USFilter.The firm was completing work in East Lynn in February 2004 when the commission fired it in a dispute over a performance bond.Financial feasibility questions are surfacing around a proposal to build an electricity-generating wind turbine off Commercial Street. Cost estimates for the 250-foot structure are now $2.5 million – an 85 percent increase since 2005.”This whole thing could end up being cost prohibitive?” Commissioner Wayne Lozzi asked Water and Sewer Operations Director Robert Tina.”It could,” Tina replied, adding that a financial analysis firm will weigh the turbine’s construction and site preparation costs against its potential for generating electricity that can be sold to offset costs.
