Some significant infrastructure projects got approved this month by the North Chautauqua County Water District board.

At its monthly meeting, the board backed the most expensive of three options laid out by the district’s engineers, CPL (formerly Clark Patterson Lee).

It’s an estimated $8.2 million plan that officials think they can pay for mostly with grant and loan funds.

CPL’s Eric Weis told the district board that when planners eyed grants to pay for new master meters between municipalities, they decided to look at other projects.

The projects — all included in the CPL option passed by the board — are:

— A new water main along Route 60 to connect existing lines in the towns of Dunkirk and Pomfret. Projected cost for $1,502,948.

— A new main for the east end of Williams Street in the town of Dunkirk for $245,788.

— A third new transmission main, this one on Route 5 in Portland, that makes any potential interconnection with the town of Westfield system possible for $627,388.

— Replacement of an existing water main along Route 20 in the town of Portland for $1,043,835.

— A replaced main for Route 5 in the town of Dunkirk, east of the city for $1,140,428.

The rest of the $8.2 million comes from a contingency fund, and legal, engineering and administrative costs.

All three of CPL’s options included the eight master water meters. The second option omitted the Route 5 projects and the third contained only the meters.

The meters are intended to check water flow between municipalities, both to help with billing and to assist in troubleshooting problems.

“It would give us a clear delineation between each municipality on water used,” said Dan Pacos, water district board chairman and Pomfret town supervisor. “It would also help us find water loss.”

He said the option to do all five water main projects “gives us two loops, Route 5 and Route 20,” which will be helpful in the event of an emergency. The option also “maxes out our funding, if we can get it. This all hinges on funding.”
