The Village of Bronxville has hired Professional Consulting, Inc., the same engineering consultant that helped with last year’s sewer manhole digital mapping project, to design a program to clean out and install cameras inside approximately 39,000 feet of sewer main.
During the mapping phase, New Jersey-based PCI helped the village’s Department of Public Works locate approximately 517 manholes—some of which clearly required rehabilitation—as well as evidence of sewer line backups and flow deficiencies.
Now that these entry points have been recorded, PCI will design a plan to clean and then install video cameras to “televise” the flow of sewage along mains in the village’s primary business district, Lawrence Park and Pondfield Road, thus making it easier to identify internal structural problems that may require attention in the future.
The Board of Trustees authorized Republican Mayor Mary Marvin to enter into an agreement with PCI at its May 12 meeting for the company to design and oversee the implementation of the program, which will run the village $14,500 for design services and $16,800 for construction oversight services.
“We will be putting out another contract for the actual cleaning and televising of the sanitary sewer line,” Bronxville Public Works Superintendent Rocco Circosta said.
“What [televising the insides of the lines] provides is documentation, obviously, to see if there are any issues within the interior structure,” Circosta said. “To do a good televising, you really want to get the lines clean. There will probably be some sediment and debris or grease along the pipes before we can really get a good visual.”
Circosta said the sewer cleaning and televising work will cost around $200,000.
Within the next month, the village will go out to bid for a construction company to do the work. There is a possibility the board will hire a company at its July meeting, the public works superintendent said.
This construction company will make use of PCI’s plan design and the technologically advanced sanitary sewer map system PCI created in winter 2013 as part of the $30,000 sanitary sewer capital plan it developed for the village.
The Bronxville DPW has been using the map since June 2013 to identify manholes and for a record of the size and elevation of sewer pipes.
The $2.78 million public works portion of this year’s $3.5 million capital budget, which is based on an annual capital improvement plan spanning five years, was approved April 7 and includes $275,000 to fund renovations and repairs to the village’s 100-year-old sewer pipes.
The focus of the five-year capital plan the board came up with this year, Marvin has said, is infrastructure and fixing roads, while last year’s focus was technology.
Mayor Marvin could not be reached for comment as of press time.
