Rihding Water is the concessionaire behind Taoyuan's sewerage BOT project. Established in 2012 under the Radium Life Tech group, it holds a 35-year contract with Taoyuan City Government covering wastewater collection, treatment, and reclaimed water supply, operating the largest public wastewater treatment system in Taiwan.
