摘要：
In presented paper two economic analysis of investments for integrated waste water collection and treatment in selected area are presented. The methods of Net present value (NPV) and Capitalised costs (CC) have been used to compare economic efficiency of construction central waste water treatment plant with collecting system and construction of decentralised waste water treatment plants with belonging collecting system for each settlement separately. Two possible solutions have been selected to cover the extraordinary maintenance costs in the life time of each construction solution.
