Project Description:
The Project will include upgrades to the biosolids facilities of the NEWPCC, including systems to convert sludge produced on site and hauled from the City of Winnipeg’s (the City) South End Sewage Treatment Plant (SEWPCC) and the West End Sewage Treatment Plant (WEWPCC) for beneficial re-use. As such, upgrades to accept, store, treat and stabilize the sludge produced from the treatment of wastewater are required. The Project scope includes design and installation of:
- a hauled raw sludge receiving facility to receive sludge from the WEWPCC and SEWPCC;
- a phosphorous release facility to promote the release of phosphorous as a separate byproduct, available for resell purposes;
- a pre-digestion sludge treatment facility to screen, blend and equalize sludge, dewater the sludge, and thermal conditioning of the dewatered sludge through the Cambi Thermal Hydrolysis system;
- an anaerobic digestion facility to digest and store the sludge from the Cambi Thermal Hydrolysis System;
- a biosolids processing and loading facility, including Ostara phosphorous recovery, chemical and phosphorous storage areas, dewatering centrifuges, truck loading area, area control and automation, field control station and employee amenities;
- a digester gas handling facility to receive gases collected from the anaerobic digestion facility for treatment to remove moisture and hydrogen sulfide, a major cause of odors; and
- associated works, such as yard work, tunnels, internal piping galleries, external wastewater/stormwater piping and water distribution, roads, landscaping, fire protection, etc.
The Work is to be performed while minimizing impact on the operation of the existing NEWPCC facility.
