Although the cost of rebuilding the town\u2019s District I sewer plant came in somewhat high \u2014 exceeding $37 million \u2014 First Selectman Rudy Marconi expects the Water Pollution Control Authority can handle it.\u201cThe estimate was $32-or-$33 million. It did come in a little higher,\u201d Marconi told fellow selectmen as they re-approved bonding resolutions for the sewer project.A total of $48 million was approved by voters last November for the sewer project, but that was projected to cover the renovation of the District I treatment plant off South Street, which came in at $37.7 million, and also the cost of closing the District II plant at Routes 7 and 35 and building a pipeline to bring that District II wastewater to the District I plant off South Street for treatment.The work to decommission the District II plant, and build the pipeline to South Street, hasn\u2019t gone out to bid yet. But Marconi said the town Water Pollution Control Authority (WPCA) was optimistic that it could cover the entire project\u2019s costs without going back to the taxpayers for more money.\u201cThe WPCA feels, within its cash flow, it can cover the difference,\u201d Marconi told fellow selectmen. \u201cIt may have to put some of its other projects on hold.\u201d\u201cRight now, we\u2019re covered?\u201d asked Selectman Bob Hebert.\u201cWe\u2019re covered,\u201d said Marconi.That was June 19. The town was awaiting action by the state bonding commission to approve borrowing \u2014 hundreds of millions of dollars \u2014 expected to cover the state\u2019s share of numerous clean water projects, including the one in Ridgefield.Marconi said in a July 1 email to The Press that the bonding commission had approved the big borrowing package. He also said WPCA chairwoman Amy Siebert had signed a contract for the work on the District I plant, and the paperwork was submitted to the state Department of Energy and Environmental Protection (DEEP) before the June 30 deadline to qualify for clean water money \u2014 although the town was still awaiting final approval.
