Reducing the phosphorus levels of Black Creek

As a result of high volume flows as well as anticipated further growth in the area, the Acton Wastewater Treatment Plant (WWTP) required expansion in order to service the Town of Halton Hills, and related environmental services associated with the Black Creek water quality.

In an effort to reduce the phosphorus levels of Black Creek to meet the Ministry of Environment (MOE) phosphorus level requirements, IBI also provided the preliminary design, detailed design, contract administration and inspection services for the capacity expansion of the WWTP facility from 4.5 Megaliters per Day (MLD) to approximately 5.6 MLD in Phase 1, and approximately 7.0 MLD in Phase 2.

The expansion included new primary clarifiers, new aeration tanks and secondary clarifiers, new deep bed sand filters, UV system and a new digestion system.
