Innovative/Alternative Onsite Wastewater Treatment Systems Task Force

The I/A OWTS Task Force works to accelerate new parcel and cluster level OWTS technologies into the market, targeting Nitrogen effluent levels of <10-11 mg/L. We are collaborating with US EPA Southeast New England Program (SNEP) which includes Rhode Island, the Massachusetts South Coast, and the islands of Nantucket, Martha’s Vineyard and Block Island.  Ultimately, these systems will have applicability to all New England and beyond.
