Pump House and Holding Tank

Once we reached the area of the pump house, we supported the master bedroom with an extra long steel beam in order to dig underneath for the holding tank. This tank would also be the foundation for another 4 season sunroom and be poured monolithically. As my contractor built the pump house, I laid the PVC piping in layers, carefully placing fine sand so pipes would not touch each other. I compacted each layer with abundant water spray and I pressure tested each line as they were completed. Once this was done, a french drain was placed around the retaining wall.
