Underground Storage for Detention
Underground Storage for Detention
(OP)
Have a project where we will have a small amount of underground storage serving as part of our detention system. It will be 5 runs of 18" diameter pipe (double wall w/ corrugated exterior and smooth interior) and each run is 200 feet long. Looking at the how the manifolds were constructed, they used heated fusion to create the tees and have straps that overlap the pipe and fittings. My question is how well do these fittings and fused seams hold up under pavement.

If you're stuck with 18", I'd say take a hard look at HDPE instead, for corrosion reasons.

I've finally got a few projects where we're speccing the Stormtech system from ADS. It's slick, just not always cost effective. Probably beats a manifold made only of 18 inch pipe though.

Biggest one I can fit given the cover constraints and fall, if it's primary objective is storage, because the biggest ones are the most cost efficient. If the primary objective is infiltration, then I back-figure the required planimetric area of infiltration bed to match the required first flush drawdown time, which is a function of site soil permeability, and I do some cost optimization about how best to cover that area with chambers. For systems that provide both functions, I do a bit of both.
I don't use the system exclusively. There's at least a dozen similar products out there.
