Over 200 miles of sewer pipe link 85% of residences and 100% of commercial properties to Fairfield’s Water Pollution Control Facility (WPCF), operating under the authority of the Water Pollution Control Authority (WPCA). The facility is valued at more than $100 million, and is operated by 18 certified town employees.

Each day the WPCF returns about 8.5 million gallons of water, cleaned in accordance with state and federal standards (>95% of pollutants removed), to the Long Island Sound.

Fifteen percent of residences are on septic systems (see link below for tips on maintenance).

Achievements to date

  • The WPCF operates with 100% renewable energy coming from a solar array installed over old landfill in 2017 and a fuel cell, online since late 2019
  • Wastewater sewer pipes are separate from stormwater pipes
  • In a process unique in the state, the 500 tons of biosolids generated annually at WPCF is combined on site with local wood debris to make valuable compost

Challenges Ahead

  • Optimizing the effective and efficient operation of WPCF
  • Protecting the WPCF from storm damage and flooding
  • Maintaining separation of wastewater and stormwater systems

Benefits of Modern Wastewater Management

  • Lower sewage fees because facility runs on renewable energy
  • Town receives rebates from the state for producing outflow that exceeds state nitrogen standards – which also protects the health of Long Island Sound.
  • Town gets revenue from the sale of compost and keeps 500 tons of biosolids out of landfill yearly

2030 Plan Goals*

  • Approval and implementation of WPCA long-term Facilities Plan
  • Completion of berm to “harden” the WPCF against 100-year flood conditions
  •  20% reduction in WPCF/sewer pipe emergency calls to relieve “fatberg” obstruction (a fatberg is a large mass of fat and waste material that forms in sewers

*Some goals are ambitious, and may need more time to achieve target participation rates; others can be achieved sooner, but work on all goals should begin as soon as possible

How Do We Reach Our Goals?

  • A detailed, 25-year Facilities Plan awaits approval by the state. The plan will bring about important upgrades to aging equipment and further enhance operating efficiency
  • Ongoing program to detect and repair pipe disruptions to reduce stormwater I&I (inflow and infiltration) into wastewater collection system
  • Ensuring that stormwater management is an integral part of infrastructure and construction planning
  • Promote commercial and residential water conservation measures: reducing wastewater reduces unnecessary throughput at WPCF, lowering operating costs.
  • Protection of WPCF and private sewer connections through education of consumers to refrain from putting any form of grease into the drain, and not flushing so-called “flushable” wipes
  • Consider regulations for “graywater” management as feasible; reusing graywater will reduce throughput at WPCF and conserve drinking water
