It is also proposed to extend the wastew'ater network, so that 50% more people can join the wastew'ater network. For this purpose it is needed to build a 2.3 km long new wastewater netw'ork (including 300 m collectors), which w'ill cost EUR 200 000. Thus, for rehabilitation and expansion of Vardenik’s w'astewater system around EUR 240 000 will be required. For this purpose it is necessary to build a wastewater network of 3.5 km length (of which 1.5 km collector to the w'astew'ater treatment plant).
