Abstract
The main goal of this study is evaluation of reconstruction options for water pumping stations, regarding various factors (equipment purchase cost, maintenance, energy consumption). The search for the most profitable solution was carried out using the life cycle cost methodology for the urban water supply system’s first lift pump station. An analysis of the operating modes of the pumping station was carried out using curves of pumps and system. It was found that the option with a higher purchase price has the best technological indicators, including energy consumption. The expediency of the complete replacement of pumping equipment is confirmed by an analysis of life cycle costs.
Highlights
According to the forecast of Analytical Center for the Government of the Russian Federation technological energy conservation will become the main direction of reducing energy intensity in housing and communal services for the period until 2040
The introduction of innovative technologies for the consumption of energy resources will lead to a reduction in harmful emissions into the environment and technogenic impact on the climate
When a reconstruction of a pumping station is planned, it is necessary to carry out an inspection of a system, which should include a study of existing operating modes of the system, a monitoring of hydrological regimes of a water supply source
Summary
According to the forecast of Analytical Center for the Government of the Russian Federation technological energy conservation will become the main direction of reducing energy intensity in housing and communal services for the period until 2040. This event can give from 25 to 30% of the total energy saving in the industry. It is necessary to strive for increase in efficiency of resource use at system level for sustainable and economical operation of urban water systems [3]. Improper matching of pump operating conditions and operation or system requirements are the main causes of lower efficiency [1, 14]
