Abstract: This paper presents a case study covering the solution to treatment of municipal wastewater originating from small villages located close to each other in a protected landscape area. A high environmental efficiency of treatment is required. Two scenarios of the technical solution are compared. In the first scenario, separate wastewater treatment plants will be built and operated in each of the villages. In the second one, sewerage networks will be built in each village and wastewater will be collected and treated in a wastewater treatment plant of a chemical factory located down the stream; the factory is planning to reconstruct and modernise its wastewater treatment plant. Analyses have shown that the second scenario is environmentally beneficial – ensuring high water quality in watercourses in the protected area, using purified water for industrial purposes primarily, and replenish the water balance and flows in dry periods. The second scenario also appears to be beneficial from a socio-economic point of view. Cost savings, appearing mostly at the side of the factory, creates space for negotiation and an agreement between these entities. The factory image will also improve if implementing the second scenario.
