Kunming Dianchi Water Treatment Co., Ltd. is a leading municipal water utility company specializing in the design, construction, operation, and maintenance of water supply and wastewater treatment facilities across China. Founded in 1989 and headquartered in Kunming, it operates primarily in Yunnan Province, where it accounts for over a third of the region’s designed wastewater treatment capacity and nearly half of its treated wastewater volume. The company’s operations are organized into segments such as wastewater treatment, reclaimed water supply—providing reused water for commercial, industrial, and government clients—and running water supply for residential and commercial use. Kunming Dianchi Water Treatment implements diverse project models, including build-own-operate (BOO), transfer-own-operate, and build-operate-transfer (BOT) concessions, partnering closely with local governments. Its broader services extend to water quality testing, solid waste treatment, logistics, training, and environmental restoration. With a strong track record of technological innovation and a robust portfolio of proprietary patents, the company plays a critical role in implementing China’s environmental strategies, particularly the restoration of Dianchi Lake. Its market significance is underscored by stable concessions, resilient financial performance, and an expanding footprint into Southeast Asia.
