WATER MANAGEMENT IN SANITARY PROTECTION ZONES OF VARAŽDIN COUNTY

The urbanization of settlements and cities and the development of industry increase the need for water, while on the other hand the discharge of wastewater increasingly affects heavier pollution of surface and groundwater, and space in the broader sense. By failing to take appropriate measures and endangering the quality of groundwater and spring water, further degradation of its quality can lead to undesirable consequences on water supply, especially in the lowland area of Varaždin County. It should be borne in mind that for some parts or areas, especially those with dispersed individual construction, wastewater drainage cannot be solved through the public drainage system, but the solution is based on individual, basically personal operations (collecting and septic tanks). In this paper the sanitary protection zones of water supply sources for Varaždin County are described, in accordance with the laws and regulations. The aim of this paper is to provide appropriate instructions or guidelines for their protection and performance in order to minimize the possible negative impact on groundwater or the environment in the broader sense.
