All the rainwater and sewage pipework has been connected into the external tanks.
Rainwater from the main and side roof areas is going to a tank in the front lawn .. about 3750 litres in a large concrete holding tank with a pump to return the water into the house for toilets etc. With extra treatment it could also be used for drinking water but no plans for that at present.
The wastewater and sewage goes to a P60 sewage system in the garden. The percolation area has been cleared and pipework laid. By tomorrow it should all be covered over and we can begin to bury it all underground and prepare the levels.
