20世纪50年代以后，全球人口急剧增长，工业发展迅速。全球水资源状况迅速恶化，“水危机”日趋严重。一方面，人类对水资源的需求以惊人的速度扩大；另一方面，日益严重的水污染蚕食大量可供消费的水资源。
中国水资源人均占有量少，空间分布不平衡。随着中国城市化、工业化的加速，水资源的需求缺口也日益增大。在这样的背景下，污水处理行业成为新兴产业，与自来水生产、供水、排水、中水回用行业处于同等重要地位。
2007年，中国水污染治理投资达到3387.6亿元，比上年增加32%，占当年GDP的1.36%。中国水环境质量总体保持稳定。2007年，共取缔一级水源保护区内排污口942个，停建二级水源保护区内可能造成污染的建设项目1294个，限期治理931个。
截至2008年10月，全国设市城市、县及部分重点建制镇共建成污水处理厂1459座，日处理能力8553万吨（36个大城市共建成288座，日处理能力为3497万吨），分别比“十五”末期增加60.5%和42.6%，全国设市城市污水处理率已由2005年的52%增加到2007年的63%；在建城镇污水处理项目1033个，设计日处理能力约3595万吨。2008年1至10月，全国已投入运行的城镇污水处理厂累计处理污水达190亿吨，运行负荷率达到76%，同比分别增长了21%和约3个百分点。
在国际金融危机的背景下，中国采取继续扩大内需，促进经济增长政策，把环境保护放在突出的战略位置。2008年四季度新增的千亿元中央投资中，投向节能减排和生态建设的资金达120亿元。用于重点流域的水污染防治工程投资及用于城镇污水和垃圾处理设施、污水管网建设提速的资金高达60亿元，前者投资为10亿元，后者为50亿元。可以说，污水处理行业迎来空前的发展机遇。
