Water Act (CWSWA) regulations, local governments are
responsible for designing, planning, constructing, financing,
operating and maintaining wastewater treatment facilities, and the
conveyance systems, known as publicly owned treatment works (POTWs).
POTWs collect wastewater from homes, commercial buildings, and
industrial facilities and transport it via a series of pipes, known
as a collection system, to the treatment plant. Here, the POTW
removes harmful organisms and other contaminants from the sewage so
it can be discharged safely into the receiving stream. Generally,
POTWs are designed to treat domestic sewage only. However, POTWs also
receive wastewater from industrial (non-domestic) users. The General
Pretreatment Regulations establish responsibilities of Federal,
State, and local government, industry and the public to implement Pretreatment
Standards to control pollutants from the industrial
users which may pass through or interfere with POTW treatment
processes or which may contaminate sewage sludge.
collection and treatment activities may also include laboratory
operations, biosolids management and disposal, chemical
storage/hazardous materials management, and vehicle/equipment
Office of Wastewater Management (OWM). OWM oversees a
range of programs contributing to the well-being of the nation's
waters and watersheds. OWM focuses on control of water that is
collected in discrete conveyances (also called point sources),
including pipes, ditches, and sanitary or storm sewers. OWM is also
home to the Clean Water State Revolving Fund, the largest water
quality funding source, focused on funding wastewater treatment
systems, nonpoint source projects and estuary protection.
Technologies. The Agency provides both direct and
indirect assistance in the area of municipal wastewater treatment
technologies. Direct assistance includes one-on-one discussions about
design, operation and maintenance of systems, and the identification
and solution of problems.
