History
The Kowloon Reservoir was the first of the group to be built. Construction commenced in 1907 and it was completed in 1910, making it the first reservoir in the New Territories. On completion, the capacity was 353 mg.[clarification needed] The total cost of construction was $619,000.
Construction of a water tunnel connecting the Kowloon Byewash Reservoir to the Lower Shing Mun Reservoir started in 2019. The project is scheduled to be completed in 2022. The Inter-reservoirs Transfer Scheme (IRTS) consists mainly of a water tunnel, 2.8 km in length and 3 m in diameter, connecting the two reservoirs.[1] The purpose of the tunnel is to reduce the quantity of the overflow from the Kowloon Group of Reservoirs into the Lai Chi Kok Transfer Scheme (LCKTS) and to make better use of the water collected by the Kowloon Group of Reservoirs which will otherwise overflow into the Butterfly Valley and discharge into the sea.[2]
