This is done in a lot of places. Especially places with deep sandy soil. Orange county California has a pretty extensive ground water recharge program. They actually inject partially treated water in a line along the coast to prevent salt water intrusion into the water tables as they pull from the aquifers, lowering freshwater tables.

Usually infeasibility is proven based on the underlying soil's conductivity . We have to do infiltration tests as part of the geotechnical investigation for the site prior to design. If the volume of water from the 85th percentile storm can't be infiltrated within a 36 hour period it's infeasible. There are other criteria like nearby utilities, steep slope, contaminated soil etc that can preclude infiltration as well. 85th percentile is based off long term (80 years) local rain gauge data. Never encountered a new fault being discovered, but most geotech investigations don't go deep enough for that.

I'm a civil engineer in CA working mostly in stormwater retention facility design. When building a new development or redeveloping in most areas of California, you have to prove that it is infeasible to infiltrate the full volume of the 85th percentile storm on site before you can consider any other methods of stormwater treatment. Onsite storm water infiltration is already a huge thing in California.

Bob Hoover's autobiography Forever Flying is an awesome read. Highly recommend it.

Reply to Financing an engagement ring for 12 months, 0% interest - is it wise? by [deleted]
I'd be really careful with that. A lot of "0% interest" deals have sneaky clauses where the moment you go over the 12 months you owe all the interest that would have otherwise accrued during that period.
