Design parameters of the household water consumption rates
and pressures in a water distribution network

Summary

Being a part of the water supply system, a water distribution network provides for the water distribution around a community and supply to the consumers. To ensure standard water supply to the consumers the minimum free pressures that guarantee uninterrupted water supply shall be provided in the water distribution network. With the introduction of the revised version of CP 31.13331 of 2021 «Water supply. External networks and structures», the principle of determining the design values of minimum free pressures at the entrance facility above the ground surface in the water distribution network of a community or city at the maximum household water consumption has changed. According to these data, the minimum free pressures in the water distribution network were calculated and their values were compared with the free pressures in the public water distribution networks that had been designed before 2021.
