H/O permit for a BBQ island. H/O is a structural engineer. I told him that he would have to cover the sink. This is what he did. He even provided a glass of water so that I could test it.

Wastewater utility prerogative . . . not a code requirement.ICE said:Justin,Just in case it rains. We don't want rain water getting into the sanitary sewer system where it will be treated.
A conservative guess on the number of these in our jurisdiction would be 5000. The gallons that they capture can't be close to 100 each, probably closer to 25. That comes out to 125,000 gallons. In a wet year that could double. I could be way off. A drop in the sewer treatment bucket.Architect1281 said:So the scope of the problem would be a 6"/24 hour 100 year rainfall event in a hole max say 6.5 square feet that produces less than a 30 gal trash can full of water. I can see where that would tax the system.
curious would the average annual rainfall even exceed 100 gal
No problem, four bricks, one at each corner and wind/rain combo cover is good to go.mark handler said:Ask the homeowner/engineer to design it for wind and rain combo
Welcome to our California world!Rio said:The amount of water that a sink like that will introduce to a sewer, as pointed out, is negligible. Outside floor drains encompassing hundreds or thousands of square feet are a valid concern but to be putting the screws to somebody because a a counter with a sink will get some rainwater in it seems to be pushing it.
