Pollution load (PSg) in accordance with these terms, using the calculated quantity of waste water per year and the average concentration per year maintenance.
Pollution — direct v ai indirect anthropogenic origin of discharges to the aquatic environment and the thermal regime, the dismantling, which endangers human health, causing damage to the biological resources and to aquatic ecosystems, as well as interference in the use of water resources.
Terrain: vie a water supply system, from which is taken the underground or surface water.
Water use: an action that creates the effect on water quality indicators for quantitative or surface and ground waters (except in ships ' ballast water, the use of which is determined by other legislation), if the following conditions are met: 1 the quantity of waste water in particular) the outlet more than 5 m3 per day;
2) ground water acquired or used in depths exceeding 20 m, or the amount of water used more than 10 m3 a day;
3) is affected surface water hydrological mode or the consumption of surface fresh waters more than 20 m3 per day;
4) the above quantities are not exceeded, but the protection of the environment and regional development Ministry of the competent institution, in its opinion, finds that the possible significant environmental impact. permission to use the water, the document that allows the user to use the water to water and water use is governed by the terms, conditions and rules, as well as setting limits.
Water conditions of use — requirements governing water user action, rights, duties and responsibilities.
Water users: any natural or legal person that collects or uses the drinking water business.
Water margin: the amount of water required for the production of unit or a specific consumer day, if water is used rationally and use technology that enables you to save water.
