Signs the whole system is due

  • A steel tank, or a tank no one can find a record of
  • Backups and surfacing effluent at the same time
  • A system that predates the house additions, with more bedrooms now than it was built for
  • A failed inspection during a sale
  • Repairs every year for several years running

What a full replacement includes

A replacement is designed as one system: a new tank sized to the bedroom count, a distribution box, and an absorption area sized to the soil. Under New York's standard, new designs use at least 110 gallons per day per bedroom, and tanks start at 1,000 gallons for one to three bedrooms. Older homes with older fixtures are designed for more flow, 130 or 150 gallons per bedroom.

The design is prepared by a NYS licensed professional engineer or architect, reviewed by the county health department, and inspected before backfill.

Which county reviews it

Most of this service area is in Onondaga County, where the Health Department's Division of Environmental Health handles septic review. Homes in Hastings are in Oswego County, where engineers submit four sets of plans to the county Health Department with a plan review fee, $125 for an individual system. Homes in Sullivan are in Madison County, whose public health department reviews alternative system designs and observes percolation and deep hole tests.

Crews that work across the three counties know the differences, and the contractor you are connected with should be able to say which office will review your job and what it asks for.

The state replacement fund

New York's State Septic System Replacement Fund, created by the Clean Water Infrastructure Act of 2017, reimburses up to 50 percent of eligible costs to a maximum of $10,000, or up to 75 percent to $25,000 for enhanced treatment systems. Design, installation and system components are eligible. Routine pump-outs, permit fees, sales tax and connecting to a public sewer are not.

Eligibility is set by the county and limited to properties near specific waterbodies. In Onondaga County that means within 250 feet of Skaneateles Lake and its tributaries, Otisco Lake, the Seneca River between the Cross Lake outlet and Klein Island, Jamesville Reservoir, or Upper Rush Creek. Madison and Oswego counties take part for their own listed waters.

Choosing the system

Where the soil allows, a conventional trench field is the cheapest and simplest. Where it does not, the design moves to a raised or mound system, a shallow trench, or an engineered design. Across much of Onondaga County the soil ratings make that second list the likely one, and it is better to hear that at the first visit than after the perc test.

House under contract and the system failed

Replacement is a design, a review and a build. Call early and say what the inspection found. A contractor can tell you the realistic timeline and what can be done to keep the house usable meanwhile.
