Construction of Macau’s first treatment plant for wastewater reuse, located in Coloane, got off the ground on Wednesday, the Marine and Water Bureau (DSAMA) announced in a statement that day.
According to Wikipedia, water reclamation, aka wastewater reuse or water recycling, is the process of converting municipal wastewater (sewage) into water that can be reused for a variety of purposes, such as the flushing of toilets, watering plants, road cleaning, car washing, and firefighting. Such water is also known as reclaimed water.
Wednesday’s DSAMA statement noted that reclaimed water in Macau will be used for two purposes, namely the flushing of toilets and watering plants.
The city’s first reclaimed-water plant will be located next to the Coloane Wastewater Treatment Plant near Concórdia Industrial Park.
The statement noted that the reclaimed-water plant will be constructed in two phases. Construction of the first phase, which got off the ground on Wednesday, will last up to 430 working days, the statement said, adding that the plant’s first phase will be able to generate 2,500 cubic metres of reclaimed water per day.
The statement said that after the completion of the first-phase construction, the plant will be able to start supplying reclaimed water to Coloane’s sprawling Seac Pai Van public housing neighbourhood and the University of Macau (UM) campus on Hengqin island in 2026.
