Abstract
Water supply pumping stations are among the main energy-consuming elements in the water supply system. The energy optimization of a pumping station can significantly affect the energy consumption of a water utility. This article deals with the energy optimization of water pumping stations. The work assumes several variants of optimization of water supply pumping stations through changes in the water supply system, pressure changes in the pumping station, and modification of the number of pumps. After analyzing the network, conducting field tests, and creating a model of the water supply network, the network was calibrated in order to reproduce the existing water network as accurately as possible. Then, a variant analysis was performed, and the best optimization method for the pumping station was selected. In two variants, there was a decrease in electricity consumption; in three there, was an increase; in one, there was no change. By connecting the DMA zones and modifying the pressure in the pumping station, the energy consumption of the pumping stations was reduced. On this basis, it was found that it is possible to optimize the water pumping station by modifying the pumping station and work related to the network layout.
Highlights
As the quality of life increases, people’s need for water increases dramatically
Water supply pumping stations are an indispensable element of any water supply system
In order to analyze the optimization of energy at water pumping stations, field tests were carried out; a hydraulic model of the water supply network was prepared and calibrated in accordance with the assumed variants
Summary
As the quality of life increases, people’s need for water increases dramatically. The optimization problem is very important to water utilities [1,2]. Water supply pumping stations are an indispensable element of any water supply system. They provide water supply to each recipient, and the required pressure on the water supply network for firefighting purposes. The cost of energy is one of the most important components of the price of treated water. They include, among others, costs of pumping and transporting water [3,4,5]. Global trends in electricity savings and constantly growing electricity prices force you to look for savings at “every step”
