Force Main
BKAAC can install a force main when gravity flow isn’t sufficient to carry water and sewage through the gravity sewage line; the force main uses the pressure from water entering the pipes combined with the pressure from gravity-fed pipes so there won’t be any backflow in the system.
Sewage Pumping Stations
We can also install sewage pumping systems to move wastewater to higher elevations so that gravity flow can be established: the sewage is stored underground in a wet well before being pumped through pipes to a gravity manhole, and then moved by gravity to a treatment plant.
