Question Shop Floor Sump Pits

Hello all,

I work in a manufacturing facility where the building is not owned by us. We recently had a random city inspection, where the city came over to inspect the integrity of our sump pits located in the shop floor.

We were using the pits to store hazardous waste water after our shop floor has been washed. Until we can isolate or improve our galvanization process, We know the zinc content in the waste water is too high to release to the sanitary or storm sewer systems.

Cracks were noticed in the sump pits upon inspection but no order was given to install sump liners or repair the cracks. We were given advice to install an "interceptor" in the overflow compartment so that any oils etc. sitting on the top of the waste would not accidently flow into the sewer systems which are connected way down the line to the sumps. This we did.

When we advised the building owner of the cracks, they insisted on filling all of the sump pits with water. Other than a static leak test, does anyone know or understand what their intention would be to leave the pits filled with water indefinitely? I understand filling them to watch or wait for leakage or evaporation, but do not understand why they would fill them, leave them that way, and refill after leakage or evaporation is noticed. Is there a reason for this other than perhaps they do not want us to use them at all? Doe filling them not make them inoperable for their intended purpose? Please help!
