We've moved into a subsection of a large commerical building with a concrete
slab and no basement. We want to install a sink, but there is no obvious
sewer nearby to connect with. Usually buildings like this have drains all
over the place, but this one appears to have very few. The closest floor
drain is 100' feet away. Maybe the others are buried in the concrete, but
we don't know and the landlord has no blue-prints.
There is a sink in the warehouse about 50' away and it has been suggested
that we drain into a 5 gallon pail and use a sump pump to pump the
wastewater over to the warehouse sink. I've seen this done before and the
pail water can be very rank. Is a sump pump arrangment like this code?
What other options are there? Is there a way to discover sewer lines buried
in the slab?
