Suffolk County’s Revolutionary 2025 Septic Regulations Are Reshaping Service Costs for Homeowners

Suffolk County homeowners are facing significant changes in septic system requirements and associated costs as new regulations continue to reshape the wastewater management landscape. Septic improvement and innovative treatment systems are required in Suffolk County in accordance with new changes passed by Suffolk County Legislature in October 2020. The changes are effective July 1, 2021 and require I/A OWTS to be installed under a number of circumstances. Suffolk County Legislature passed new changes in October 2020 that require septic improvement and innovative treatment systems, effective July 1, 2021.

Understanding the New Regulatory Framework

The most significant change affecting Suffolk County residents involves the mandatory installation of Innovative and Alternative Onsite Wastewater Treatment Systems (I/A OWTS) for specific circumstances. New houses built in Suffolk County that are not serviced by sewers are now required to have state-of-the-art nitrogen reducing septic systems under legislation that Suffolk County Executive Steve Bellone signed last Thursday, October 15. The legislation, which the Suffolk County Legislature adopted unanimously, furthers the county’s efforts to reduce nitrogen-loading in the county’s bays and other waterbodies and to protect drinking water.

Nitrogen-reducing systems are required for new family residential construction, major reconstruction projects, new multi-family or non-residential projects, and all new commercial projects. Reconstruction projects are considered “major,” when the costs of reconstruction are 50% or more than the market value of the structure. For example, if a structure’s value is $100,000 and it costs $60,000 to reconstruct or repair, this would fall under the “major reconstruction” classification.

The Environmental Imperative Behind New Regulations

These regulatory changes stem from urgent environmental concerns. Suffolk County has put these new regulations in place to address the problem of nitrogen entering ground and surface water. High nitrogen levels cause harmful algae blooms that impact water quality, create water dead zones, increase the treatment cost of drinking water, and stifle some ecosystems. The Suffolk County Wastewater Plan, adopted in July 2020, estimated that there are 365,000 residential onsite sewage disposal systems installed in Suffolk County, of which 252,530 are estimated to consist of cesspools only.

An innovative/alternative septic system reduces nitrogen output by 70 percent or more, compared to a conventional system. An innovative/alternative system is required to reduce nitrogen to 19 milligrams per liter.

Impact on Service Costs and Homeowner Expenses

The new regulations have created substantial financial implications for Suffolk County homeowners. On average, the cost to replace an outdated system with an approved one is $19,200. Of course, these costs will vary, but the price can be steep for the average homeowner. Some systems can cost even more, with I/A septic systems that can cost upwards of $30,000 — and even considerably more.

Regular septic pumping costs have also been affected by the regulatory changes. Pumping a septic tank typically costs between $300 and $600. However, homeowners with newer I/A OWTS systems may face additional maintenance requirements and costs due to the advanced technology involved.

Licensing and Industry Standards

The county has implemented strict licensing requirements for septic industry businesses. Any work that requires pumping, servicing, cleaning, system rehabilitation services or minor repairs to residential, commercial, and/or industrial conventional septic systems, cesspools, and wastewater holding tanks, and/or performing assessment of the overall health of a conventional septic system and/or coordinating preventative maintenance and pumping with property owners, requires this endorsement.

Successful completion of a Long Island Liquid Waste Association (LILWA) training class and passage of the LILWA certification test; or Successful completion of a similar training program approved by the Department. These requirements ensure that only qualified professionals handle septic services in Suffolk County.

Financial Assistance Programs Available

Recognizing the financial burden on homeowners, Suffolk County and New York State have established several assistance programs. The Suffolk County Septic Improvement Program provides up to $10,000 base grant. There is also up to an additional $10,000 that can be awarded to a grantee that installs a pressurized shallow drain field leaching system ($5,000) and/or toward the unit installation for low to moderate incomes eligible applicants ($5,000).

Currently, Suffolk County and New York State provide grants. For the county, grants rise as high as $10,000. An additional grant of $5,000 can be made available for certain applicants. The state grants can amount to 50% of “eligible” costs, not including sales tax, pumping out of the old system and certain internal plumbing requirements, up to $10,000.
