Wastewater Treatment Facilities (WWTF)

Nineteen major wastewater treatment facilities in Rhode Island purify some 100 million gallons of human and industrial sewage every day. Hundreds of miles of sewer lines – from a few inches to 9 feet in diameter – and hundreds of publicly and privately owned pumping stations add up to a sizable investment in clean water, most of which is the responsibility of Rhode Island's cities and towns. DEM's Wastewater Treatment Facilities Program regulates this infrastructure through two programs:

  • The Planning & Design program provides reviews and approvals of wastewater facility plans and issues Orders of Approval for design plans and specifications for the construction of wastewater treatment plants and wastewater collection systems to ensure adequate and effective transport and treatment.

The O&M program also supports Rhode Island’s wastewater operator certification program, providing training and assistance to wastewater personnel.
