The Conservation Board consists of up to nine members appointed by the Town Board. We function in an advisory capacity to the Town Board, Planning Board and Town Engineer.  Present efforts are focused on public education related primarily to protection of our surface and groundwater resources. Ninety-five percent of North Castle residents rely on drilled wells for their water supply.

In recent years, the Conservation Board has prepared public education information on Lawn Care & Pesticides, groundwater, leaf composting, pesticides & toxic free living, wetland buffers, and Septic Systems How they work and how to care for them.  All information relates to the protection of our drinking water - both surface water and water pumped from wells.

The recent adoption of a Town law, effective May 1, 2011, requires property owners in the Kensico and Croton watershed areas of North Castle to have their septic tanks pumped once every five years. These watersheds are only a small area of the Town.  The Byram Lake, Byram-Wampus and the Mianus watersheds cover the majority of the town.

Properly cared for, a septic system is a highly effective way of handling household wastes.  One of the most important things you can do to keep your septic system functioning efficiently is to have it pumped out regularly to help protect the leaching fields and avoid problems that may lead to a huge future expense.
