JULY EDITION

Works located next to drainage channel leading to the River Lodden -
On returning to site after the Christmas break the site was found to be flooded. This washed away
temporary roads and turned the site into a mud bath.
To cope with the heavy rainfall, the team have installed a french drain which filters the water through to
one of the on-site structures that is acting as a holding tank. It is then pumped to a settlement tank and
discharged to an area of land agreed with Thames Water (via a TWOSA).
Management techniques
• Water sampling - to ensure minimal silt accumulation
• RAMS - specific to dewatering
• Recorded using the Permit to Pump form - the site records pictures of settled out sample bottles
and test the pH.
Traffic Management
• Due to space constraints, efficient traffic management has been imperative. The use of a one way
system for deliveries to site, as well as clear pedestrian walkways and barriers have been effective
in reducing the risk moving vehicles pose to site personnel.
• Banksmen are also used to negate any potential problems caused during the operation of
excavators, dumpers and rollers.
No Injuries on site in over 67,800 man hours
IN THE SPOTLIGHT
BASINGSTOKE CHP
The Basingstoke Thermal
Hydrolysis Plant (THP) that
includes additional digester
capacity and CHP generation
is part of the AMP6 strategy to
eliminate lime sludge treatment.
The end goal is that after start-up,
the THP and generation system will
be self-sufficient. Surplus power
generated, will be consumed by the
rest of the works and any surplus
above this will be exported to grid.
