The conditions for industrial effluent discharges to the municipal sewerage system

The industrial waste waters of an urban area are jointly treated with municipal sewage waters. The operation of the municipal sewage treatment plant depends substantially on the quality and quantity of industrial waste water conducted to the treatment plant for joint treatment and drainage. In order to guarantee the normal run of the plant a number of normative documents have been worked out regulating the discharge of industrial effluents to the municipal sewer network. Detailed requirements for individual industrial enterprises have been elaborated on the grounds of these documents by the local bodies of Water Supply and Sewage Management. The local requirements are coordinated with the institutions for the regulation of water utilisation and water conservation under the USSR Ministry of Land Reclamation and Water Conservation and the Ministry of Fisheries and are confirmed by local municipal authorities. Control over the implementation of obligations is exercised by Water Supply and Sewerage Management authorities. The discharges of industrial effluents to municipal sewer network have to meet both general and specific requirements
