I am trying to dig a septic tank for my newly constructed house at Whitefield in Bangalore. But the digging has come up against rocks in the ground is there an alternate way to handle / build the septic tank in this case . The plot is about 4000sq ft with the building in the majority portion and 1000 sq ft available for the septic tank. The tank should be able to support a 5 bathroom house. I am willing to try alternative technologies as a remedy. Kindly advise on further action.
