Home Flood-Proofing Assistance Program
About the Program

The Village of Westchester is served by separate storm and sanitary sewers.  During some intense rains, the capacity of the sanitary sewer system is not adequate to carry the peak flow, resulting in pressurized sewers.  When pressurized, the sewage can backflow through house sewers into basements if there is no backflow prevention.

The Village has decided to help the owners of owner-occupied single family homes and two-flats defray a portion of the costs of providing protection from the backup of sewage in the basement.  The grant program’s intent is to offset a portion of the expense that a property owner will incur to revise the house plumbing such that sewage cannot backflow into the house when the sanitary sewer is pressurized.  To revise the house plumbing, there are three basic options available to the property owner, as listed below:

1)      Modification of the soil stack to direct flow out of the house in a new OVERHEAD SEWER and the elimination of all gravity drainage below the basement floor slab.

2)    Installation of an interior or exterior BACKFLOW PREVENTION VALVE and bypass pump on the house lateral in an underground vault.

3)   LIFT STATION system with an inside or outside underground vault. 



Each approach has different costs and degrees of property owner disruption, as well as different implications on the homeowner’s use of the revised plumbing.

A license plumber can determine which option best serves your need.

Updates or enhancements to current overhead sewer or lift station systems are not eligible for this program, however, replacement of an old system is eligible under this program.
