Case Study: Hunter Water Corporation improves air diffusion at Toronto WWTW with Pensar

Hunter Water Corporation upgrades 2 EATs with Pensar, keeping operations running

Hunter Water Corporation faced the challenge of upgrading the Extended Aeration Tanks at its Toronto wastewater treatment works to improve air diffusion. The project required navigating a brownfield environment to install new diffusers and undertake significant concrete repairs while maintaining full plant operations. Pensar was engaged to provide a solution for this critical infrastructure upgrade.

Pensar successfully designed and constructed the upgrade, which included installing new diffuser systems and a specialized lifting frame. The team expertly managed the decanting and hydromining of sludge from the tanks, a process that provided a large cost benefit for Hunter Water. Through ongoing collaboration, Pensar delivered a successful outcome for all project phases, ensuring the new systems were commissioned while keeping the existing services fully operational.
