Hall Water Treatment Works
GTM JV (Galliford Try and Imtech Process) managed this project on behalf of Anglian Water, which required the delivery of various schemes to increase the supply of treated water to the Lincoln distribution network by 20 Ml/d from a new water treatment works.
The mandate for this project covered the construction of Hall WTW and associated pump station(s), and the connection into two existing distribution mains with nitrate blending control system. The proposed solution was a new green field stand-alone water treatment works located in the vicinity of the existing Newton WTW and borehole site, producing 20 Ml/d of treated water.
The treatment process of the proposed works at Hall is as follows:
- River Water Abstraction via Inlet Pumping Station
- Raw Water Reservoir Storage
- GAC Roughing Filters
- UF Membrane
- UV Peroxide
- GAC Absorber Filters
- UV Disinfection
- Distribution via storage reservoir
