By the late 1980s the system had reached the end of its useful working life. Morton Dam was decommissioned and emptied of its water. In 1993 a new state-of-the-art treatment plant was built. Water is now taken directly from weirs in both the Wainuiomata and Orongorongo catchments. The new plant produces up to 60 million litres of high quality water per day and supplies about 15 percent of the water used by greater Wellington.
