Blackford to Ickenham

POSTED ON: 14/04/2020

In April 2020 Risk Management Limited were instructed by Affinity Water to undertake an intrusive soil investigation to determine the proposed route for a 700mm diameter mains between Blackford Booster and Ickenham Booster. The project was part of a larger 20-year investment programme named Supply 2040

A total of 22 No. boreholes were drilled along 3 proposed linear routes for the mains pipeline using a tracked window sampler rig. Boreholes were drilled to depths of between 2.00m and 10.00m below existing ground level.

A large area of the site comprised a former Landfill and in addition to geotechnical testing on samples recovered to aid sub-structure foundation advice, numerous contamination and waste acceptance criteria (WAC) tests were scheduled to provide information to assist in the best possible route for the mains pipe.
