A Major Achievement

Successful in tendering and completion the Rauparaha Street Sewer Pump Station Upgrade Project at a cost of $1.3M. This involved the duplication of the existing pump station down to a depth of 7 meters that linked up the existing / new pump station wet wells with a Low-Level connection. A major variation to the Contract required us to re-design the wet well construction due to unforeseen ground conditions. It included the refurbishment of the existing pump station as well as constructing large diameter bulk sewer mains (at depth in the middle of Te Moana Road) that linked up both pump stations via a large diameter flow splitting chamber. (Contract period – 1 year)
