About wastewater

The Environmental Services Department is responsible for the maintenance and operation of the Exeter Wastewater Treatment Facility (WWTF); associated sanitary pumping stations; forcemains and the wastewater collection systems in Crediton, Centralia, Huron Park and Exeter that convey wastewater to the Exeter WWTF.

The Department is also responsible for the operation and maintenance of the wastewater collection system and associated sanitary pumping stations in the Grand Bend Area that convey sewage to the Grand Bend Area Wastewater Treatment Facility. The Grand Bend Area WWTF is jointly owned by the Municipality of Lambton Shores and South Huron and are operated by OMI Limited. The Department is responsible for the enforcement of the Municipality's Sewer Use By-Laws.

Wastewater collection system (sanitary sewers)

South Huron's wastewater collection system is designed to collect and direct wastewater to a wastewater treatment facility. Wastewater is treated in order to make it acceptable to be introduced back into the environment. To protect the health of our residents and the safety of the environment, we use modern technology at our sewage treatment facilities. The following components are part of the system to convey and treat wastewater generated by residents and businesses in South Huron:

  • 62 kilometres of sanitary gravity sewer
  • 10 kilometres of forcemain
  • 500 sanitary access manholes
  • 6 sanitary pumping stations
  • 2 sewage treatment facilities

Sanitary sewers carry wastewater from homes, commercial buildings and industrial sources to one of two wastewater treatment facilities. After treatment the water is returned to the Ausable River. During heavy rainfalls, older sanitary sewers, especially in Exeter, can become overloaded and may overflow into the Ausable River. To address this environmental and financial issue, South Huron has begun a program that aims to reduce the inflow and infiltration of storm water in our older sanitary sewers.

Wastewater discharged into sewers is regulated by South Huron's Sewage use by-laws for Exeter, Huron Park, Crediton and Centralia. Wastewater rates and charges are regulated by the Water and Wastewater Rates and Charges By-law. You can obtain an official copy of these by-laws by contacting the South Huron's Corporate Services/Clerks Department at 519-235-0310.
