Temporary Water Supply during Watermain reconstruction

Temporary Water Supply during Watermain reconstruction

Temporary Water Supply during Watermain reconstruction

(OP)
Does anyone have standards for temporary water supply to residents during a watermina reconstruction project.  Any help with minimum pipe sizes, both for main and services, or perhaps a specification detail would be greatly appreciated.

RE: Temporary Water Supply during Watermain reconstruction

Your main problem is maintaining a minimum fire water supply ??

RE: Temporary Water Supply during Watermain reconstruction

What exactly are you doing.  Replacing with open digging, pipe bursting, lining, etc.?

If you are just laying a new larger main by open digging, then keep the existing main in service during the laying process, get it connected (so 2 mains will be in service), switch the services over, disconnect and abandon the old main.

Other options (bursting/lining) could require temporary above ground pipe or connection of hydrants.  Length and size of existing main that will be replaced in one pull will help you decide what size temporary you will need.  I'd do a system analysis to see what flows are available when specific lines are out of service.

If your lines are looped, you might not need any temporary.  Why not specify that the line length being replaced cannot exceed what can be reconnected within one working day?
