I'm designing a retention pond based on Urban Drainage (Colorado Front Range) which requires 1.5 times the 24-hour 100 year storm plus 1 ft freeboard.
I'm familiar using the 1 - 6 hour point rainfall values for varying design storms because it's listed in Urban Drainage. However I don't...
Thank you guys for your input.
I'm a little awestruck, because I thought the majority of hydrants in local developments were rated for flows above 1000 gpm but most designs I see are with 6" laterals.
Anyways thanks you for all the info, I will use it wisely.
Thank you, so that means in order to meet a fire flow requirement of 1500 gpm I would likely always need 2 hydrants?
So then in WaterCAD what is the best way to model hydrants, should you add actual 6" lines with hydrants and look to total flows based on the specified hydrant spacing. Or pull...
This may be a silly question, but then how would standard fire flows (ranging anywhere from 1500 gpm to 3500 gpm) be required from a hydrant that is typically off a 6" lateral?
I ran another model with a hydrant attached to a 16" main with plenty of pressure and attached to reservoir and I...
I'm not extremely familiar with WaterCAD v8 and working on a smaller commercial site that needs a service stub and fire hydrant. Existing infrastructure consists of a 16" main in the frontage road to the project with an 8" lateral stubbed at the project entrance.
I've set up a model with a...
