- Client: Watercare Service Limited
- Year: 2010
The main contract was awarded to Service Engineers Limited who subcontracted Coastline Construction Group for all civil and building work, and Current Electrical for electrical works.
The contract involoved all works required for raising the Outlet Structure of Secondary Settling Tank No1, pipe capacity increase and flow meter installation in Lagoon 2 bypass line and modifications to the Low Lift Pump Station to accomodate a future Lagoon operating procedure in a more energy efficient manner.
Service Engineers Limited's scope included civil demolition, construction of concrete weir areas inside Low Lift Pump Station, the fabrication and installation of a 1300 diameter pipe spool, installation of the flow meter and building a concrete structure/tank for raising outlet structure and associated mechanical extension for penstocks.
The project has presented challenges with confined space, as well as keeping the plant operational where possible. There was also restricted timeframes for out of service areas such as the Low Lift Pump Station modifications.
All staff working on the site had to be fully immunised against all possible diseases and infections associated with waste water treatment plants. There was also a risk of engulfment in work areas and working within confined space.
The project was delayed due to overseas delivery of penstocks but is now on schedule for completion in mid December 2010.
