Implementation of a constructed wetland wastewater treatment plant for 150 people - Museum in Svätý Anton

This project involves the construction of a constructed wetland wastewater treatment plant serving the museum in Sv. Anton. The manor house was completed in 1750 and its history is closely linked to the Koháry and Coburg families; it is a national cultural monument.

The investor's brief was clear: to build a wastewater treatment plant that is functional, requires no maintenance, requires no electricity or spare parts, and blends seamlessly into the environment. Therefore, the only and most suitable solution for the museum was a maintenance-free constructed wetland wastewater treatment plant—Ekočistička®—and an artificial evaporative wetland.

The constructed wetland wastewater treatment plant not only serves a functional purpose, as it treats wastewater water for 50,000 annual visitors and 25 permanent staff, but it also brings aesthetic value and fosters biodiversity. The constructed wetland works using gravel, sand, and wetland plants, in whose roots live beneficial bacteria that break down bacteria in the wastewater water.  Contaminated wastewater water enters two vertical filters planted with approx.  950 plants, which, in combination with the filter media, purify the wastewater water up to 99%. The treated wastewater water is collected in an artificial wetland. This entire system significantly supports the biodiversity of the landscape. The treatment plant hosts a variety of insects and bees, and the wetland is home to birds, such as ducks. Last but not least, water evaporates into the environment instead of running off into streams and seas, thereby contributing to cooling the landscape and making the environment more pleasant.
