Bolivar Wastewater Treatment Plant Odour Control Project

The odour control project at Bolivar Wastewater Treatment Plant was designed to eliminate nuisance odours and reduce nutrient levels.

This involved replacing the existing biological filters, which were the main cause of odours from the plant, with a new activated sludge treatment process to significantly reduce nitrogen and odour levels.

York Civil was the prime contractor undertaking all works using its own plant and labour.

Works involved the construction of a reinforced concrete reactor consisting of four tanks, detailed excavation for footings, concrete floors, footings, walls and soffits, and supply and installation of fifty cast-in pipes.
