Hi, what are my options please? I know about the sprinkler type but I'm nervous about never being able to use mould killer in my shower- is this really strict or can I get away with it? I was told that the other option where the truck comes to empty your tank costs $300 four times a year to empty- does this sound right? Thank you

you will have to see what council requires in your area
in my area
a large tank which the liquids drain to a leech field
the solids are emptied every 3 years at $300
new build near me require the treatment plant
which must be serviced regularly
mould killer in the shower is fine in normal amounts
remember a shower will add 80 litres of water to the tank, multiplied the number of people in your house

Your council will have a requirement of what type of system you can install.
We have an aerated waste water treatment system, which discharges fully treated water to a disbursement field and does not require pumping out.
The waste is broken down by bacteria inside the tank so you have to be careful what you put into it - eg bleaches and products like Exit Mould are a big no no.

Just correcting the terminology:
* A system which collects sewerage, that is not aerated, the liquid is drain into absorption trenches and the solids are collected periodically (2 to 5 years depending on the size of the household and the tank) is called a septic system. This type of system has been used forever.
* A system that has multiple chambers, a pump to aerate and converts the sewerage to "useable" liquid is called a biocycle. These are newer. They were very popular for a while, but they must be inspected regularly (at some cost) and some councils will now not allow the liquid to be used in the open.
We built a house recently and went for the old fashioned type because there was little advantage in a biocycle because we were required to discharge the liquid underground, and the downside of the costs for regular inspections.
BTW, you can't use strong disinfectants, bleaches and need to be careful of antibiotic use for either system as they both rely on microbes.

Yeah, I had heard there was legislation coming in banning electric HWS's. I think I'd also read some discussions about exempting HWS's connected to solar PV from this…
