5.13. The free pressure in the external network of the domestic drinking water supply for consumers should not exceed 60 m.
Notes. 1. Free pressure in a residential area should be consistent with the provisions of SP 30.13330.
2. If the pressure in the network is more than 60 m for individual buildings or areas, the installation of pressure regulators or zoning of the water supply system should be provided.
6. Sources of water supply
6.1. As a source of water supply, one should consider watercourses (rivers, canals), reservoirs (lakes, reservoirs, ponds), seas, groundwater (aquifers, under-channel, mine and other waters).
For industrial water supply of industrial enterprises, the possibility of using treated wastewater should be considered.
As a source of water supply, bulk reservoirs can be used with water supplied to them from natural surface sources.
Note. In the water supply system, it is allowed to use several sources with different hydrological and hydrogeological characteristics.
6.2. The choice of water supply source must be justified by the results of topographic, hydrological, hydrogeological, ichthyological, hydrochemical, hydrobiological, hydrothermal and other surveys and sanitary surveys.
6.3. The choice of the source of domestic and drinking water supply must be made in accordance with the requirements of GOST 17.1.1.04.
The choice of the source of industrial water supply should be made taking into account the requirements imposed by consumers on water quality.
The sources of water supply accepted for use are subject to agreement in accordance with the current legislation.
6.4. For domestic and drinking water supply systems, the available groundwater resources that meet sanitary and hygienic requirements should be used to the maximum.
In case of insufficient operational reserves of natural groundwater, the possibility of their increase due to artificial replenishment should be considered.
6.5. The use of groundwater of drinking quality for needs not related to domestic and drinking water supply, as a rule, is not allowed. In areas where there are no necessary surface water sources and there are sufficient reserves of groundwater of drinking quality, it is allowed to use these waters for industrial and irrigation needs with the permission of the authorities for regulating the use and protection of water.
6.6. For industrial and domestic drinking water supply, with appropriate water treatment and compliance with sanitary requirements, the use of mineralized and geothermal waters is allowed.
6.7. The availability of average monthly water consumption from surface sources should be taken from Table 4 depending on the category of the water supply system, determined in accordance with 7.4.
6.8. When assessing the use of water resources for water supply purposes, the following should be taken into account:

A break in the water supply or a decrease in the supply below the specified limit is allowed for the time of turning off the damaged and turning on the reserve elements of the system (equipment, fittings, structures, pipelines, etc.), but not more than 10 minutes.
Second category. The value of the allowable decrease in water supply is the same as in the first category; the duration of the decrease in supply should not exceed 10 days. A break in the water supply or a decrease in the supply below the specified limit is allowed for the time of turning off the damaged and turning on the reserve elements or carrying out repairs, but not more than 6 hours.
Third category. The value of the allowable decrease in water supply is the same as in the first category; the duration of the decrease in supply should not exceed 15 days. A break in the water supply when the supply drops below the specified limit is allowed for no more than 24 hours.

per day of average consumption - average hourly consumption;
per day of minimum water consumption - the minimum hourly consumption.
Carrying out calculations for other modes of water consumption, as well as refusing to carry out calculations for one or more of these modes, is allowed when justifying the sufficiency of the calculations carried out to identify the conditions for the joint operation of water conduits, pumping stations, control tanks and distribution networks for all characteristic modes of water consumption.
Note. When calculating structures, conduits and networks for the period of fire extinguishing, emergency shutdown of conduits and lines of ring networks, as well as sections and blocks of structures, is not taken into account.
7.10. When developing a water supply scheme, a list of parameters should be established, the control of which is necessary for the subsequent systematic verification by the operating personnel of the compliance with the project of the actual water consumption and uneven water consumption coefficients, as well as the actual characteristics of equipment, structures and devices.
