Rehabilitation of the amenities and engineering networks of Gudiashvili Square and surrounding streets in Tbilisi (2017)

The project involved the installation of separate stormwater and wastewater networks from Lermontov Street to Asatiani Street, connecting to the existing main collector. Pipes of various diameters were used for the drainage system, with reinforced trench walls and newly constructed manholes. Additionally, a dual drainage system was implemented to manage groundwater beneath restored buildings. Existing sewer connections were replaced up to individual buildings and yards.
