Wastewater Pump for basement laundry room for 20 unit MFH

[Jordan F.]

Hi Everyone,

We are thinking of installing a laundry room for a 20 unit apartment building that has no laundry onsite.  We have a basement available but would need to install a sump pump or some other pump to pump the water into the drainpipe which is in the crawlspace.  There is already a sump pit but I'm wondering about what kind of pump and the durability of a pump that might have to pump water 12 feet up and 5 feet across for 3 or 4 washing machines at the same time.  Any ideas?  Thanks.
