Fleetwood Waste Water Treatment Works
GHA Livigunn were appointed by KMI+ to provide detailed Civil, Structural and Architectural Engineering Design on this £45M Fleetwood WwTW Scheme, which is now nearing completion.
Completed Site
The project is a refurbishment to the existing works required to meet the EA requirements for discharging final effluent into the North Sea. Improvements were made to Fleetwood WwTW to cater for increased population in the catchment. Flows to full treatment were increased to 198,000 m2/3 day.
Working as part of a fully integrated delivery team, GHA Livigunn undertook civil and structural design for the following elements:
- 2 No. detritors
- Ferric storage and dosing system
- 4 No. Primary settlement tanks (PSTs)
- New sludge treatment process building, screens and Pumping Stations
- Odour control plant for the primary treatment and sludge treatment areas
-New roads and hardstandings
Particular attention was paid to the foundation design solutions adopted. This was due in part to the site's former use as landfill and the need to minimise waste material being taken off site. In addition the main inlet sewer had been constructed as a tunnel running underneath the site of the new PSTs. Auger Displacement Piles were adopted which in turn minimised vibration and potential damage to the tunnel whilst also eliminating contaminated arisings.
Innovative Moving Shuttering System for PST Walls
Due to highly contaminated ground conditions, (part of these new works are built on a 1970’s land fill site) special material handling measures were required. This necessitated the production of a 3D model of the site and the production and approval of a materials handling plan prior to commencing the works.
