Water Act (CWA) 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
Guidance Memorandum. Provides guidance to the regulated community and permitting authorities on the impact of the Supreme Court's decision of County of Maui v. Hawaii Wildlife Fund on CWA Section 402 National Pollutant Discharge Elimination System (NPDES) permit program. Outlines seven non-exclusive factors to evaluate whether a point source pollutant discharge that travels through groundwater can be treated as the equivalent of a direct discharge to Waters of the United States in the context of the existing NPDES framework.
Memorandum on Interim Strategy for Per- and Polyfluoroalkyl Substances (PFAS) in Federally Issued NPDES Permits. Recommended actions for implementing EPA's interim PFAS strategy. Listed actions focus on adapting NPDES permitting practices to increase monitoring for PFAS in NPDES permitted facilities. Additionally, details EPA's future plans to promulgate information-sharing on PFAS monitoring between facilities.
CWA Analytical Methods for PFAS. Information on EPA's development of novel analytical methods to test for PFAS in wastewater, groundwater and surface water.
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.

Federal Funding for Utilities - Water/Wastewater - in National Disasters (Fed FUNDS). The purpose of Fed FUNDS is to provide tailored information to water and wastewater utilities about applicable federal disaster funding programs. The Fed FUNDS Web pages address national-level disasters, but could also apply to large-scale and even local disasters that result in service interruptions and significant damage to the critical water/wastewater infrastructure.
National Environmental Training Center for Small Communities (NETCSC). Through U.S. Environmental Protection Agency (EPA) funding, NETCSC assisted small communities with training materials, information, and referral services in the areas of wastewater and drinking water. Through the efforts of technical assistance providers and trainers the program benefits local decision-makers, operations personnel, regulatory officials, environmental consultants, and others by aiding their efforts to improve the public health and water utilities management of their communities. NETCSC's training materials and products are currently available.

Provides further guidance on conducting system assessments and identifying priority areas for improvement. Information on conducting workshops and trainings on this manual are available in EPA's companion publication, "Workshop in a Box: Sustainable Management of Rural and Small Water and Wastewater Systems Workshops."
Making the Right Choices for Your Utility: Using Sustainability Criteria for Water Infrastructure Decision Making. Provides water and wastewater utilities with a six-step process to compare and choose between competing infrastructure alternatives. The process highlights considerations, including the creation of sustainability and performance goals and the determination of common and relevant evaluation criteria, to ensure a municipality's selected infrastructure will meet its regulatory requirements.
