Battersea Case Study
Battersea Water Treament Works Case Study
of Contract: IChemE Purple Book design and build
Programme: August 2003 to January 2005Due to the pressures exerted by the Environment
Agency Thames Water were encouraged to utilise their existing borehole licences. As such an existing borehole on the Thames
Water ring main site at Battersea was earmarked for further development.
Due to the nature of the water quality
it was identified that aeration and GAC were required, however in spite of these treatment processes the water quality still
did not meet strict DWI requirements. It was therefore decided that the water produced from the plant would be blended at
with the water in three strategic mains crossing the site. This entailed six months of planning as the existing water mains
that fed the majority of south London had to be isolated and cut into to insert the new mixer. An additional risk that had
to be considered and managed was the age of the existing water mains which were circa 1908 with lead run joints.
Once complete the plant was capable of delivering 7.8Ml/d into the respective zones.
- Constrained high security site with a highly
populated underground services
in time deliveries due to severe lack of storage
to be undertaken around strategic cast iron water mains
- Complex interdepartmental stakeholder management
