On 30 November 2021, Macao Water, a SUEZ subsidiary, officially commissioned the newly completed Seac Pai Van Water Treatment Plant. The new facility will increase Macao Water's total daily water supply capacity from the current 390,000 m3 to 520,000 m3, a level sufficient to meet Macao's growing water demand for the next decade. The project represents a new chapter for Macao's water supply industry. In light of Macao's urban development master plan, and to enable complementary water supply in the north and the south, the Macao SAR Government reached a cooperation agreement with the Mainland China water authorities, to jointly construct the fourth water supply pipeline to Macao and build a fourth water treatment plant (WTP). This new WTP will be based on Macao's outlying island and will have a daily treatment capacity of 130,000 m3, mainly providing water supply services to local residents, as well as to industrial and commercial customers. This new development will further improve the security and stability of Macao's entire water supply.
