The services required in this lot are based on provision of trained/skilled leakage maintenance technicians, to undertake field based observational activities in specified DCC water network areas. There is also a requirement for office based analysis to undertake data reviews and advise field based terms on work planning and scheduling. Tasks shall include delivering and undertaking sounding on all DCC assets and locating possible leakage instances, reporting these into DCC systems. Field resources will be required to undertake comprehensive leakage detection surveys on DCC assets. Areas will be pre-defined by in work packages let by the DCC leakage team, with the main purpose of the work under this lot to reduce leakage. There will also be a requirement to undertake leakage and demand investigations/surveys on trunk main service reservoir assets. The scope will focus on installation and maintenance of logger, control devices and other consumables (LRP’s, Pulse units/cables) purchased by DCC under separate supply agreements. DCC’s current logger estate is c.10 000 and predominantly comprises of cellos to monitor both flow and pressure, this is likely to grow by a further 10-20 % over the next AMP period.
