Water intake facilities are an integral part of the construction industry. The choice of the water intake scheme, its operational characteristics, depend on the capital costs for the construction of the water intake, as well as the creation of better conditions for the operation of equipment and networks. The cost of these facilities is very high. Therefore, when designing them, it is necessary to choose the optimal design scheme and operating modes during the design life. Operational experience has shown that in order to ensure the most optimal conditions of water intake from an underground source, it is desirable to have a well in one line. In the calculations, the influence of wells on each other is taken into account as in group work, if the distance between them is less than two influence radii. This arrangement of wells allows to reduce the area and capital costs for the construction of water intake, as well as to create the best conditions for the operation of equipment and networks. The calculation of the group of interacting wells is to find the number of tubular wells, the distance between them, flow and levels (static and dynamic). When determining the operation modes of the combined water conduit, it is necessary to take into account the joint operation of clean water tanks and tubular wells. The diameter of the collecting water pipe must be increased, with an increase in the number of wells to be connected, and therefore an increase in the flow rate. The linear scheme of connection of wells on water intake from an underground source of water supply is the most common in the practice of construction and operation of groundwater water intakes, when wells are used as water intake devices and it is necessary to improve the quality of the water extracted from the aquifer before supplying it to the consumer. On water intakes containing a large number of wells located along the river at a certain distance from it, the calculations use a formula that allows the replacement of a real number of wells by a gallery at a rate of 1 m in length.
