Infiltration under an underground parking lot?
Infiltration under an underground parking lot?
(OP)
We are working on a mixed use development, and the city has a couple of different options with how to handle the water for their requirements. The first one they prefer is to capture to the 3/4" storm and infiltrate. This particular project takes up the entire site and has 2 levels of underground parking. Is it possible to infiltrate under a building?
On a side note what are the best ways to get water out of an infiltration tank system if you can't bubble out of the outlet. We try to stay away from infiltration whenever possible, but it looks like this will slowly be the only method we can use in certain cities.

As for bubbling up from the outlet, If it will not flow by gravity and you cannot infiltrate, then pumping is the only option left, an option not allowed by many municipalities. Some have allowed it with a backup emergency generator in the case of an extended power outage - an additional cost.

And we try to stay far away from pumps as possible. Those lately have been a nightmare to deal with. I keep hearing it doesn't rain in California the last few weeks from way too many contractors and Architects.

Keep it under the parking lot...that works with proper design and construction.

I don't care who says it's OK. As a licensed structural engineer, I would never stake my reputation on it, let alone the lives of others.
