What Haitian Water Group does

Haitian Water Group Co., Ltd. (海天水务集团股份公司, ticker 603759.SH) is a Chengdu-headquartered, publicly listed Chinese diversified environmental services group operating across two main pillars plus adjacent verticals. Its core business is municipal water supply and wastewater treatment delivered through long-duration concession contracts with city governments across Sichuan, Henan, and selected international markets, supported by nearly 200 environmental factories and more than 50 subsidiaries. The group's second main pillar is new energy and new materials, established in April 2025 through the CNY 502 million acquisition of Heraeus' photovoltaic silver paste business; this pillar is anchored by a priority-purchasing agreement with Tongwei Solar, the world's largest solar cell maker, running through the end of 2030.

The company monetizes through multiple revenue streams: recurring subscription-style fees from municipal water and drainage concessions, hardware sales of silver paste and related PV materials to solar cell manufacturers, managed services for solid waste treatment via joint ventures (notably the Zhonghai Kang vehicle with Kangheng Environment), subscription fees for pipeline direct-drinking-water services using end-point purification, and professional services for engineering construction. Go-to-market is enterprise and government field sales with direct B2B relationships; customer concentration on the PV side rests heavily on Tongwei Solar, while municipal counterparties are diversified across provinces.

Technology assets include 154 international and national patents, 35 standards the company helped draft, a National Enterprise Technology Center designation, and an R&D headquarters that won a Muse Design Platinum award in 2025. The group has expanded beyond traditional water into energy storage (via a strategic investment in Xingzang Century in 2024), pipeline direct drinking water (via the 2025 Sichuan Haitian Sub-meter Water Supply subsidiary), and Middle East market entry (via the 2025 Saudi Haitian registration). Strategic cooperation with China Everbright Environment in January 2025 added a state-owned partner for SOE-private collaboration on environmental projects.
