Russian environmental regulations anticipate requirement of rating of contaminants’ discharge with wastewater, of water consumption and draining, calculation and reporting, waste discharge to water bodies control. It is essential to get objective data about wastewater sources, water rotation systems, volume and structure of wastes. This data can be received within the plant’s water industry research with documentation of allocation of sources per production processes and areas, volumes and structure of wastes, with pollutants listing and their volumes. Such documentation is made during waste discharge sources inventory.

Unified guidelines and procedures of waste discharge sources inventory have not yet been developed. Therefore big enterprises have no summary and detailed documents of water industry, full data of the sources and disposal lines locations, accurate quantitative and qualitative characteristics of contaminated water directed to treatment plant, recycle or discharge to water bodies.

During a water industry practical research and waste discharge rating we have developed main approach and regulations of waste discharge sources inventory taking.

Main tasks of inventory have been stated: making a full list of waste discharges with their locations and technological features indication, organization of data on wastewater volume and composition, creation of database for water conservation measures development.

Precedence rule and content of inventory works have been established. They include the following: preparatory stage; fixing of analysis points and responsibility limits of the plant’s subdivisions; determination of qualitative and quantitative characteristics of waste discharge sources according to the list; determination of qualitative and quantitative characteristics of water recycling; metering and analysis; received data validation; final listing of waste discharge sources and their qualitative and quantitative characteristics; listing of sources polluting water recycling; received data analysis; making proposals for reduction of water consumption, draining and waste discharge.

Wastewater inventory at the plants of different sectors were performed. The methods were introduced and improved in the process of work.

In many cases the inventory results allow to work out instructions for wastewater regulation, water consumption reduction, passing of some wastewater to existing or new water recycling systems that lead to respective decrease of wastewater volume and pollution.

Inventory results can be used as follows: planning of water conservation measures (selection of priority-driven pollution sources) for bringing wastewater into line with legislation; enterprise certification in accordance with ISO 14000 (ecological management system); local ecological monitoring system establishment; allocation of pollution taxes to the plant’s subdivisions; working out measures aimed at environmental effect reduction by decrease of natural water intake.
