2025 August continued - Plumber greywater installation day 2

     The pipes from the bathroom. There is the laundry tub which includes the washing machine, then the hand basin, then the shower/bath. The floor drain in the middle of the bathroom floor is a separate minidrain.

     The bathroom drainage system required an air vent, so this goes up the south side of our house to vent above the roof level. You can also see the strapping which is hanging down from the floor joists to hold the pipes in place. All the pipes have to be sitting at exactly the right height and the right angle to give it the right amount of fall so that gravity can send the water downhill. The plumber did an amazing job.

     The pipe drops down into the ground at the end of the house, and goes through an inspection point and then a pipe 30cm below ground level.

     The pipe goes down to another inspection point and then turns a corner where it splits into two pipes, which each split into two pipes and lead to more of those purple upside down buckets with holes in them, where the waste water can drain under the ground.

     The bathroom has 4 drainage points while the kitchen only has 2. This is because of the larger amounts of water expected through the bathroom.

     A raised swale of dirt was required on the uphill side of the drainage areas, so that any water running down the hill will be diverted. This will keep the drainage area as dry as possible to help with the absorption of the wastewater from the house.

     The rest of the area is flattened off so that it can be just mowed over when the grass grows back. There could be the option to plant shrubs around the drainage area but it's better to have short green grass to help protect the dwelling from bushfire.

     This second day required twice as much sand to fill in the pipe trenches, so Josh had to move 2 tonnes of sand purely by muscle strength! We got there in the end, and are very happy with the results. The council inspector approved the system with constant photo updates sent by the plumber. We have been very happy with the results and highly recommend this system. Go to greywater.com.au for more information.
