Simultaneity and diversity for water supply infrastructure

[tj00343]

Hello,

Is anyone familiar with the French Standard DTU for water supply infrastructure networks. I'm not understanding how to apply the diversity factors and coefficient of simultaneity to calculate the instantaneous maxumum demand and where to apply it. I was thinking of applying the formula for simultaneity to each building internally and this would account for diversity inside the building but would completely disregard it outside leading to an over sized network .Especially since I plan to apply the flows in water cad at the nodes that represent the inflow to the building as the flow requirements of the buildings differ. Any advice on how I can account for diversity in the network with this method

Hello,

I am familiar with the French Standard DTU for water supply infrastructure networks. The diversity factors and coefficient of simultaneity are important considerations in calculating the instantaneous maximum demand for a water supply network.

To apply these factors, you will need to first determine the peak demand for each building or area in the network. This can be done by analyzing historical data or conducting a survey of the water usage patterns in the area. Once you have this information, you can apply the diversity factors and coefficient of simultaneity to calculate the instantaneous maximum demand for the entire network.

It is important to note that diversity factors and coefficient of simultaneity should be applied to both internal and external flows in the network. This will ensure that the network is properly sized to meet the demand of all buildings and areas.

In terms of applying the flows in water cad, you can use the peak demand values calculated with the diversity factors and coefficient of simultaneity to determine the appropriate flow requirements at each node in the network. This will help ensure that the network is properly designed and can meet the water demand for all buildings and areas.

I hope this information helps. If you have any further questions or need clarification, please don't hesitate to ask. Best of luck with your project!
