Abstract
The paper is devoted to the problem of optimal design, construction and operation of water supply systems and their elements. The key element of the system is a water well. The quality of its design and construction determines the operation of the water intake as a whole. Disadvantages in the construction of a well lead to disruption of the entire water supply system of a particular object. The paper proposed a methodology for selecting the optimal diameter and length of the well filter of a water well. Based on the methodology, an example of filter parameters selection for hydrogeological conditions of the city of Kursk is given. The above calculation showed that the use of the entrance velocity criterion in the design of wells can significantly reduce the cost of well construction while ensuring the design flow rate and allowable lowering of the water level. The cost of the filter, depending on the well design, is 20-30% of the total price for its construction. The most important filter parameters affecting the cost of a well are its length and diameter. Justifying the minimum diameter of the filter that ensures the designed water intake and allowable dewatering can significantly reduce the cost of the well, taking into account the fact that modern pumping equipment allows the use of columns of small diameter above the filter.
Highlights
Due to the growth of individual residential construction and the development of lifesupport communications, problems arise in the design and construction of water supply systems for small communities, individual residential and industrial facilities.The most important element of the water supply system are water inlet structures, which determine the operational reliability of the entire system and its technical and economic indicators [1]
In solving common problems of drinking water supply from underground sources, an important role is played by the tasks of optimal design, construction and operation of water supply systems and their elements
The choice of a water supply system for individual consumers from borehole water intakes is the key to normal operation and maintenance of buildings
Summary
The most important element of the water supply system are water inlet structures, which determine the operational reliability of the entire system and its technical and economic indicators [1]. In solving common problems of drinking water supply from underground sources, an important role is played by the tasks of optimal design, construction and operation of water supply systems and their elements. One of the most common problems of well operation on water is the clogging of the filter zone and the well filter.
