Water systems may have a Loop or Branch network topology, or a combination of both. If any one section of water distribution main of a loop system fails or needs repair, that section can be isolated without disrupting all users on the network.
The earlier construction of water supply pipe network is mainly branch network in order to save cost, which cause waste of pressure in some part of the pipe network and cannot ensure normal water supply downstream if accidents happen. With the accelerated process of urbanization, we must reform the earlier planning of water supply pipe network to improve the efficiency of water supply and ensure water supply safety. When updating the pipe network, it is common to combine branch network and loop network to make the main-pipes close as loop network. This transformation achieves maximum water transport capacity, ensures water supply safety, and is more economical. The branch-pipes employ branch network, use different water supply systems and water resources to achieve the best water supply effect.
Weltpure’s Closed Loop Network Solution determines the best solution among a large number of closed loop network plans and unicom plans through hydrological modeling and optimization. A variety of water scenarios such as water use seasonal fluctuations, maintaining water stability, water distribution and other factors are considered when determining the best solution, which is in order to meet the following requirements:
>> Improve network layout in accordance with the city planning, the possibility of phased construction of water supply system is considered;
>> Updated network layout need to ensure water supply safety, should reduce water break to a minimum when accidents happen in partial network
>> Pipeline should across the whole water service area, should endure enough water and water pressure when accidents happen
>> Ensure laying pipelines in the shortest distance in order to reduce the cost and energy consumption of water supply
