The basic water fee is the water resource fee for personal use, and the sewage treatment fee is the fee charged by the urban centralized sewage treatment facilities for providing sewage treatment services to the polluters in accordance with the regulations. These two charges are nationally recognized and determined by local government departments after holding a hearing. The sewage treatment fee is determined according to the principle of compensating the operation and maintenance costs of the sewage pipe network and sewage treatment facilities and making reasonable profits. The taxes levied on sewage treatment fees are income from engaging in qualified environmental protection projects.
