If there are septic tanks in a community, there can be shelters underground

38. Thanks for the info

As an aside, one of my clients owned an apartment building...which burst into flames one night. Apparantly, the gas station across the street had a leaky tank, which slowly created an underground plume of fuel...it eventually reached the basement of the apartment building, and the furnace touched off the vapor.

The Dept of Health and Environment came and dug a trench on his property, which repeatedly filled with gas and water...they would pump it into a truck and take it off-site. My client had to pay for all of this - the theory being it was his property, so the bill goes to him. And it is left to him to sue the gas station later.

The tank had recently passed a pressure test, but they pulled it out of the ground...pin holes everywhere! Apparantly not enough to fail pressure test, but enough to leak alot of gas.

Anyway, I can certainly see the utility of secondary containment. I assume the monotoring wells at gas stations are in the secondary containment?
