Sewage treatment

From the raw water to the tap water, to the tap water supply customers, to the sewage treatment plant after the final treatment, and then into the natural water body after completion of the treatment, the industrial chain of sewage treatment is a closed loop of water circulation. From the era of planned economy to the present, China's sewage treatment industry has gradually entered a stage of rapid development. China's urban sewage treatment has developed rapidly in both quantity and quality. National policies encourage multiple investment entities to jointly develop urban sewage treatment. Since 2014, the PPP model of the sewage treatment industry has gradually emerged. Based on “share of benefits, risk sharing, and long-term cooperation”, the infrastructure of the government and the company in sewage treatment facilities has gradually become full. According to China's "13th Five-Year Plan", the water treatment industry will exceed the trillion market size, with huge market capacity and numerous investment opportunities.
