On‐Line Rehabilitation of Large‐diameter Water Mains in Hong Kong
This article reports on one of the largest pipeline rehabilitation programs in the world, replacing approximately 3,000 km of Hong Kong's water mains in four stages at an estimated total cost of approximately HK$14 billion (US$1.78 billion). The article specifically details a section of the first stage of construction work, rehabilitation of approximately 3 km of 700‐mm‐ and 800‐mm‐diameter water mains that run directly beneath the traffic lanes of Tolo Highway, one of the most important transportation links between Hong Kong and mainland China. Project constraints are discussed, along with the evaluation of alternatives to using conventional open‐trench methods. The option of close‐fit on‐line rehabilitation was selected using a polyethylene (PE) liner pipe. Liner design considerations, installation, and benefits are discussed.
