Bedford Hills – Katonah Business Sewer District

The Town has taken the next steps on the sewer project with the hiring on June 6 of the engineering firm, Woodard & Curran, for the design of the sewer system. The Town Board’s action followed the successful referendum on March 30, 2017 among the property owners in the Bedford Hills – Katonah Business Sewer District voted in a Special Election authorizing the creation of the sewer district and a $1.2 million sewer bond (less than 5% of the cost of the project).  The design of the system requires enormous detail and care to ensure that the system is constructed in a cost-effective manner, is robust and best serves the property owners in the district.   It is anticipated that the design phase will take approximately 12 months and actual construction another year.   While it will be each property owner’s responsibility and expense to construct the waste lines from the owner’s building to the property line, we will be available to work with owners and their contractor to help reduce owner costs. We also will be available regarding the Westchester County and NYS Department of Environmental Conservation requirements for “decommissioning” the septic system.

The Town Board has asked staff to prepare recommendations regarding the unallocated capacity of the wastewater treatment plant (WWTP) which the Town will take over from the NYS Department of Corrections and Community Supervision (presently serving only the Bedford Hills Correctional Facilities).   After creation of the sewer system, the WWTP will serve the central business districts of Bedford Hills and Katonah, the correctional facilities, Katonah Elementary School, property of St. Mary’s Church in Katonah and Bedford Park Apartments in Bedford Hills (together with a few other public buildings).   There will be remaining capacity of approximately 64,000 gallons per day (GPD).  As a point of reference, the average household would utilize approximately 400 GPD.   The Town Board will implement a sewer law governing everything from permissible waste to capacity allocation. As part of the capacity allocation component, the Town Board is considering staff recommendations that the unallocated capacity be distributed as follows:

  1. Sewer District Properties

Properties within the proposed sewer district will be permitted to use up to 15,000 gallons per day of uncommitted capacity on a first come/first served basis.

  1. Out of District Properties

Residential or commercial properties outside the sewer district with cesspools or with failing septic systems and along a newly installed sewer main will be permitted to connect to the sewer main at the property owner’s cost on a first come/first served basis. These properties will be able to use up to 15,000 gallons of uncommitted capacity. Properties in this situation may utilize the Town’s Septic Reimbursement Program to pay for 50% of the cost to either connect to the sewer system or to repair a failed system.

  1. Sewer Law Review

The newly enacted Sewer Law will include regulations governing the future connections to the sewer system. In this case, the law would specify the 15,000 gallon limits in items 1 and 2 above. The law will also determine estimates of sewer flow from newly connected uses, calculations for uncommitted capacity, application procedures and requirements, and costs and fees for future connections.


Review of the Sewer Law by the Town Board will be required for the following reasons, whichever first occurs:

  1. Five years from the adoption of the original Sewer Law.
  2. Sewer District properties using uncommitted capacity over 15,000 gallons per day.
  3. Out-of-District properties using uncommitted capacity over 15,000 gallons per day.


In its review, the Town Board will be permitted to modify any of the initial capacity allocation requirements or any other provision of the law. Of course, the Board could conclude that no revisions would be required.
