SAK Construction is nearing completion of a $US2.9 million contract to install 1.5 km of 1.2 m cured-in-place pipe in sanitary sewer lines beneath the 1757 Golf Club in Virginia, US.
The cured-in-place pipe (CIPP) project is a key part of an ongoing rehabilitation of Washington DC’s Potomac Interceptor – an 80 km gravity-fed sewer system that transports wastewater to the Blue Plains Advanced Wastewater Treatment Plant for the District of Columbia Water and Sewer Authority (DC Water).
According to DC Water, the sewer’s vents have become a source of odour, especially in warmer temperatures. In 1999, DC Water began planning for a program to abate these odours with a scheduled completion date of late-2016.
SAK Construction Atlantic Division General Manager Bob Stier said the CIPP arm of the project required SAK to install the liner through two existing manholes and complete the entire project in 240 days without disturbing the golf course.“This was a challenging project that required SAK to configure the necessary bypass pipelines in a way that would not impact the surrounding areas or operations of the golf course,” said Mr Stier.
Despite the handicap, the CIPP project is scheduled for completion in February 2015 – five months ahead of schedule.
