Scope of works
Five valves were found to be seized by the main contractor during a refurbishment project on a service reservoir. Two valves were scours, two were the reservoir outlets and one was a line valve.
Penstock release at Hampton Loade Treatment Works
During routine operations for pump replacement at Hampton Loade Treatment Works a critical penstock on the High Lift Pump Suction Wells jammed. Investigations by site staff ascertained that the penstock was ‘stuck’ in a midway position. This did not prevent the suction well from being returned to service, but would stop any further similar work from being undertaken until resolved.
