Sewage Sump Pits
Sewage Sump Pits
(OP)
Guys,
Is it acceptable if multiple sewage sumps are connected to a single large sump pit from where it will then be disposed off to the site sewage network?
All 3 sump pits are at the same level, below grade.

It allows operating pump to not short cycle. If a single pump cannot keep up, then another pump, and possibly another.
All the pumps should be sized, at a minimum, to handle the expected peak flow into the sump pit. I prefer to the last pump as a back up in case one of the others is not operational.

Thanks for the reply but,
I mean to ask if one sump pit can collect sewage from multiple sump pits and then dispose of to the network.

I do not know why you would do this inside a building. Typically the only reason sewage is pumped is that it cannot flow by gravity. In fact most codes require it to go by gravity if it can.
I do not know I would want to depend on two pumped systems in series inside the building. It increases the likelihood one of the pumps will fail and there will be sewage back up inside the building.
