Pollution Control

Pollution Control & Sewage Treatment

Pollution Control is responsible for the operation and maintenance of the Leamington Pollution Control Centre and a network of municipal storm and sanitary pumping stations.

The Leamington Pollution Control Centre is located at 435 Seacliff Drive East, Leamington, Ontario. The plant treats sewage from the serviced urban area, as well as hauled waste from septic systems. It is a conventional activated sludge plant with a rated capacity of 35,000 cubic meters per day and a peak flow rate of 70,000 cubic meters per day. The plant consists of screw pumps, bar screens, grit removal, primary clarifiers, aeration system, secondary clarifiers, ultra-violet disinfection and a storm water retention basin.

The collection system is comprised of 13 sanitary pumping stations and 3 stormwater pumping stations. Discharges to the collection system, for treatment at the plant must meet the requirements of the Leamington Sewer Use By-law.

Public Education

Protecting the Sewer System and Wastewater Treatment Plant

How can you help?

  • Your kitchen sink and toilets are not a garbage disposal. Leftover grease and oils from cooking should never be flushed or poured down the drain. Instead, soak or collect the grease and dispose of in the garbage.
  • The tiny stickers on fruits and vegetables should be removed and thrown in the garbage. They can cause maintenance issues at the treatment plant.
  • Flushable wipes or baby wipes should not be flushed down the toilet (even though they say flushable)! These products should be disposed of in the garbage as they can get caught in sewers or pumps causing maintenance issues. They could even get caught in your sewer connection and cause a sewage back-up in your house.
  • Do not flush: wipes, feminine products, band-aids, dental floss or soiled tissues.

Sludge produced in the wastewater treatment process is lime stablized and dried on-site using the patented N-Viro process. The N-Viro process is a cost effective and efficient sludge recycling operation that produces a uniform product for agricultural land application. The final product is registered as a Schedule 1 Fertilizer with the Canadian Food Inspection Agency. For more information visit the N-Viro website.
