Water Quality


 

Croatia is one of thirty most water rich countries in the world. Environmental protection and drinking water supply have become a major problem and challenge for the survival and development of civilisation. Drinking water is becoming the main resource in the 21st century because of increases in population and changes in living standards.
Today we can hear on a daily basis how drinking water is likened to “new oil” and that wars will soon be fought for water. Zagreb has enough drinking water for its future generations and there are no signs of any shortages.
From the beginning of Zagreb’s Waterworks (1878), citizens of this city can boast to be drinking water that is, in view of the soil structure of Zagreb’s Sava aquifer, of exceptionally good quality and at the same time bacteriologically and chemically sound.

Water quality control in the water supply systems of Zagreb and Samobor is carried out by the Water Quality Control Service, the internal laboratory of Vodoopskrba i odvodnja d.o.o. while the official control of water safety for human consumption is carried out by the authorised laboratories of the following institutions:

1.    Andrija Štampar Teaching Institute of Public Health – controls water safety for human consumption at the hydrants of all water wells, water storage sites, and in the distribution network of the City of Zagreb,
2.    Institute of Public Health of the County of Zagreb – controls water quality in the distribution network that is managed by Vodoopskrba i odvodnja d.o.o.in the area of the County of Zagreb (Town of Samobor and suburban areas).

The Water Quality Control Service of Vodoopskrba i odvodnja d.o.o.defines the Water Quality Monitoring Programme for the Water Supply Systems of Zagreb and Samobor in accordance with the “Act on Water for Human Consumption” (Official Gazette 56/13, 64/15) and the Ordinance on Conformity Parameters and Analysis Methods for Water for Human Consumption (Official Gazette 125/13, 141/13, 128/15), on the basis of daily value measurements of water quality indicators in underground water, which is collected at the wells of water sites, and in water for human consumption delivered to consumers via water supply facilities and the distribution network.
