The government has introduced sewage charges. All water users who discharge their sewage to public sewers pay a basic sewage charge and trades and industries whose effluent strength exceeds that of domestic sewage also pay a trade effluent surcharge.

• 政府已实施排污收费制度：所有向公共污水渠排污的用水客户，均须缴付基本排污费；污水量高于住宅用户的工商业客户，另须支付工商业污水附加费。
