GILFORD — Town Administrator Scott Dunn told selectmen Wednesday the piping system for the Town Hall forced-hot-water heating system will likely need to be replaced along with two boilers in 2017.
Dunn said the piping deficiencies were noticed by the construction crews installing the heating system in the new police station addition.
"They are afraid to cut into those pipes," Dunn said, explaining to the board that as the police station is being constructed, crews need to tie into the existing boilers.
"The piping for the circulation is extremely corroded," he said.
He said the crews fear that the existing piping is "very brittle" but have to cut into it to complete the loop. He said the construction team will test the water in the system now and then flush it.
He said it appears the water is "just eating away at the pipes". Dunn said the water in the system is filtered and runs through a water softener but the pipes are made of steel which corrodes faster than does copper or plastic piping.
There are already a few leaks in the system and Dunn said the hope is that connecting the new police station system won't create any more.
He said yesterday that the two of the three boilers in Town Hall are already scheduled in the Capital Improvement Plan for 2017. He said it is very likely the piping system for the Town Hall will be added to the plan.
Dunn said that the pipes in the police station will not need replacing in 2017 because they will be new.
In other town news, the Selectboard unanimously accepted the proposed 10-year road construction plan prepared by Public Works Director Peter Nourse.
Nourse said his goal is to protect as much of the good roads by implementing an "robust" road sealing plan that will "save the town hundreds of thousands in road construction over time."
He will also address poor sections of "connector" roads first. A connector road is a road that connects a number of different roads — like Morrill Street and Belknap Mountain Road — and that, given a $1-million annual budget with a 5 percent compounded annual increase, the department can either repair or reconstruct all of the main connectors in five years.
Nourse's plan calls for spreading the work geographically around Gilford unless is makes sense to do a section of road at one time. To that end, he added that many of the roads in Gunstock Acres will be addressed sooner rather than later.
His recommendations for 2016 summer road reconstruction projects include a portion of Mountain Drive, the west side of Summit Avenue, Saltmarsh Pond Road, Poor Farm Road, a portion of Cumberland Road and Weeks Road.
Nourse recommends shims and overlays for several other roads in 2016 including Foxglove Road, a portion of Deer Run Lane, Hickory Stick Lane, Buckboard Drive, Crestview Drive, Hermit Road, and Forest Drive.
His total proposal is $1 million and a total of 5.25-miles of road will be addresses. His estimated cost per mile is $240,000 for reconstruction and $105,000 for shims and overlays.
