A 50 year old house on the fringe of Sydney. We don't have town water so we have 2 old concrete tanks connected to the gutters - the front of the house connects to a dry system and the back to a wet system. The pipe is 90mm round
The house is a single story, long rectangle with a lounge room sticking out the back. Its 30m long and 9m wide. The lounge room is 7mx 5m. The roof is tile and pitched. The gutters are half round
The concrete tanks are not level. The main tank which all the roof pipework currently feeds is about 20cms lower than the 2nd tank. The main tank has an overflow about 10 cm down from the top. The other tank has no overflow. The top of the highest tank is about 15cm under the bottom of the gutter
The house has only 3 downpipes - 1 which takes the entire front of the house and 2 for the back - 1 which takes about 80% and the other the remainder (ie the lounge room)
The concrete tanks have 2 outlets in them.. 1 right at the bottom which I use to drain the tanks when I clean them and the other about 60cm (guessing) above the base which is used to feed the pump (and equalise the tanks)
What I'd like to do
- Get rid of all the existing ugly pipework
- Capture more rainwater (we lose a fair bit during big storms)
- Make the system easier to maintain
What do I need to do ?
