Engineering and economical comparison of the surface runoff disposal options

Summary

The results of an engineering and economical comparison of two surface runoff disposal options are presented. Option 1 involves the use of treatment facilities discharging the effluent into a water body; option 2 involves the use of a storage tank followed by the discharge of surface runoff into a public sewer. The comparison was based on life-cycle costs over a 25-year operational period for new construction of treatment facilities with a capacity of 250 m³/h and storage tanks with a capacity of 6,000 m³. Option 2 involving surface runoff discharge into a public sewer, was determined to be the most cost-effective, with an economic efficiency of 214.75 mln rubles. This 46.59% economic efficiency is achieved by reducing capital expenditures. Furthermore, one of the main expenditure items is the sewer user fee that virtually offsets the difference in operating costs.
