Drake, sorry I haven't been on this part of the forum for a while and didn't see your question until just now. The water from the bath goes through a sand filter and then into a 250 gallon tank. The toilets are plumbed directly to this tank, which has a solar powered pressure boost pump on it. When the toilet is flushed, the pipework pressure drops, which turns on the tank pump. It runs until the toilet fills, the valve shuts, pipeline pressure rises above a preset point and then turns the pump off. This saves a massive 43% on our water usage. Cost to install was $50 for the 1000 litre IBC tank, $70 for the pump and then a bit of cable and pipe. Water here is $9 per 1000 litres. Typically our 4 person house does 35 flushes a day at 6 litres each, so this saves $1.89 per day, or $690 a year. Our actual water bill is $918.14. It was $1608.48.
