Effect of roof tanks filling on the hydraulic performance of water supply pipes network

Abstract EN

Assiut city suffers from lack of available lands to build houses.

The price of an apartment in Assuit city is considered the highest price in Egypt.

So, people are forced to replace the old houses with 11 floors ones.

This situation makes the city infrastructure under pressure and challenges.

One of these challenges is the drinking water supply network, which is designed to lift water only to the third floor.

In this situation, to feed the floors above the third floor with water, roof tanks are built above towers and are supplied with water from the main network through private pumps.

These pumps fill the tanks through a short period and operate for limited times at a day.

The water supply network is not designed for such type of operation.

In this research, the effect of existing roof tanks on the flow behavior in the water supply pipes network is studied.

Different Scenarios are considered for roof tanks filling through changing the period and time of filling.

The actual pipes network is planned to serve new area and all the building in this area have 11 floors towers.

For each scenario, pressure head, velocity and water age at different nodes and pipes in the network are predicted through extended period simulation.
