Management and Economics in construction is submitted by this article as a settlement tool for construction justification of blower stations. These buildings with powerful units are under financial provision of communal wastewater utilities. Economic management implemented by usage of LCC analyses, which supposed to support decision making process. LCC analyses refer to its application with and without consideration of discount rates (DR, DR-out, DR-with). Also investigated variants of blower types: multistage without control (v1), multistage with VFD control (v2), single stage dual vane control (v3). The result of LCC analysis (DR-out) shows, that last variant 3 is most cost-effective for investments with economy of: 26,9% to (v1) and 21,7% to (v2) under the identical duty conditions. Consideration of discount rates (DR-with) resulted the same as: 21,5% to (v1) and 19,7% to (v2). The power consumption plays a significant role in LCC estimation. The result of LCC analysis (DR-out) shows the proportion “energy/LCC”: 94,9% (v1); 87,1% (v2); 84,5% (v3). Consideration of discount rates (DR-with) resulted the same as: 92,5% (v1); 81,1% (v2); 76,6% (v3). The reached power saving for all control methods of blower regulation are inside range 14,3–34,9%.
