St. Lawrence Septic Grants Start With the Waterbody Map
St. Lawrence County septic-replacement funding is tied to priority waterbodies, so the county map is the early eligibility check.

St. Lawrence County’s septic-replacement program is not a general promise for every rural system. The EFC Septic Repair Program is geography and condition dependent, and income is not part of eligibility.
The geography piece is the heart of it. Funding is tied to septic systems within 250 feet of parts or all of listed priority waterbodies.
The list includes places such as the Grasse River, Oswegatchie River, Raquette River, Star Lake, and the St. Lawrence River. Those names matter because a nearby stream or lake is not enough by itself; the county’s priority list and map still control the early screen.
The county offers an interactive mapping tool. A parcel highlighted in gold is within the 250-foot threshold, but the page warns that the map is not survey quality and may not be exact in every case.
That makes the map a starting clue, not a guarantee. A homeowner should still gather repair notes, contractor estimates, photos if relevant, and the exact property address.
Then the next call can be specific: Planning for the grant path, Public Health for the septic-health side, and a qualified local professional for the actual system work.
