Case study 
The North Kaohsiung Reclaimed Water Promotion Project connects wastewater treatment with industrial demand. The Ciaotou and Nanzi reclaimed water plants are designed to supply industries, including semiconductor manufacturing, with the aim of reducing competition between industrial and domestic water uses during droughts. Their combined planned capacity is 105,000 cubic metres per day, with the plants expected to reach full capacity in 2027 and 2030, respectively. The case provides an entry point for cities seeking to coordinate water reuse, industrial development and adaptation planning, with careful attention to water quality and phased implementation.
This publication is part of the Kaohsiung-ICLEI Climate Neutral and Smart City Case Study Series, highlighting innovation in the City of Kaohsiung.
