At present, the Třešť-Buková district has no public sewerage and wastewater treatment plant. Wastewater is collected in technically unsuitable pits and septic tanks, with an ambush into the Bukovský creek. The project deals with the construction of a new sewage sewerage system and a new WWTP with a capacity of 120 EO in the city district Třešť – Buková. Connecting the new sewage sewage system to the new wastewater treatment plant ensures the removal and cleaning of sewage waters in accordance with the applicable legislation of the Czech Republic.
