STORM DRAINAGE LEVELING OPTIMIZATION
The paper proposes an optimization procedure of storm water drainage system leveling. The life-cycle costs of a wastewater disposal system are taken as optimization criteria. The optimization procedure is based on a multi-step incrementation of conditionally optimal solutions by the dynamic programming scheme. The parameters to be optimized are the slopes of gravity sewers, heads of pumping stations and drop structures. Conducted computing experiments have shown that wastewater disposal system optimization by the life-cycle cost criterion allows to find the option with the lowest operating costs including the costs of electrical power.
