Village of Ardsley, owns and maintains the sewer collection system in the Village, which is entirely a gravity system consisting of approximately 130,000 linear feet of gravity sewer pipes. The Village is a Municipal Separate Storm Sewer System (MS4) regulated by the NYSDEC with respect to stormwater collection and discharge.

To support the Village’s proactive maintenance of the sanitary sewer system, Delaware Engineering was contracted to perform sanitary sewer mapping and prepare recommendations. The sewer system evaluation characterized the system, identified potential deficiencies, and provided a prioritized list of recommended capital improvements.

The scope of the comprehensive sanitary sewer evaluation included flushing all or some portions of the collection system to remove grease build-up and debris to ensure that video inspection of the entire system possible. CCTV investigation was performed in specific sections to determine deficiencies that need to be addressed. The whole of the evaluation concluded in a prioritized list of recommendations and associated costs for proposed system improvements.

This working document is used to determine the best course of action over the next several years to address sewer replacements and repairs.
