At present, there is no public water supply in the village of Vavřinec. The village is located on the map of drought. Citizens are supplied individually from their own wells. Current resources are insufficient to supply the village of Vavřinec in terms of capacity and quality. For this reason, it is necessary to build a public water supply connected to a sufficient source of drinking water in the residential unit of interest. Together with the implementation of the water supply, the construction of sewerage of the village by pressure sewerage at the Uhlířské Janovice WWTP will also be carried out.
