Tertiary Wastewater Treatment

Tertiary treatment was necessary to support regulatory requirements for Phosphorous at <2mg/l in worsbrough but teams faced challenges;

Hydraulic challenges within the existing final effluent line
Spatial constraints in location in interception point between FE connection and outfall
Site operations to be maintained throughout build

Working closely with the construction team to gain a deep understanding of the planned construction techniques and to identify a buildable solution.

A pumping station sunk below the level of the adjacent water course, careful management of hydraulic levels and consideration of on site space to deliver a design output aligned with optimum construction technique on first pass.

Solution used a transfer chamber to intercept the FE line and enable a new pumping station to be built offline.
Pumping station facilitated flows through tertiary treatment before gravitational return to outfall.

The Solution

ESL produced a novel design for tertiary treatment works supportive of hydraulic and spatial constraints.
Site upgrades: Design for chemical dosing including delivery bunds, roads and site drainage including novel cable trough solution incorporated into existing lagoon and designed for safe maintenance.
UMON 4 design for storm overflow and building modificaitons to incorporate new poly dosing, new MCC equipment and cabling, sludge thickener upgrades and feed pipe and drain modifications with louvres for climate control and SR4 security rated doors.
