I have a fairly narrow lot 12.5 x 30 and our estate does not have recycle water system in place, because of which I need to install a tank. I was wonder if the council will allow me to have a slim tank on the side rather than at the back, as I would not have a large back yard. The side set back would be about 915mm.
The alternative is to have an underground water tank, I was wondering what would be the cons on that - anybody here have experience on placing the tank underground and will there be any maintenance issues?
Appreciate any information on this.

What is your mandated volumetric retention?
You can buy tanks that are slimmer than slimlines.
You are not restricted to just one tank and multiple tanks don't have to be grouped.

Thanks for the link.
This tank is bloody awesome! I have no idea on the mandatory volumetric retention, is that something I could find out from the council?
My land is located in NW Sydney, I need to check with my builder if they stock these tanks OR I must find a way to get this done by own.

In NSW, the required on site retention is determined by BASIX as far as I am aware but the council could have a say. With a bit of luck, Stewie will be able to advise as to the procedures.
There are many types of tanks and if you have a raised decked area, fitting one or two suitable tanks underneath the deck would also be good. My advice though is to steer clear of bladder tanks because they don't breathe plus they are expensive. If applicable, have a look at the type of tank in the ATA link below.
The thin tanks are pricey for their size but they are made to solve a space problem plus they can also create privacy. Delivery areas include Sydney.

If you decide to use these tanks, you also need to tell your builder that the tanks require leaf diverters to be fitted to the downpipes.
One thing that concerns me is the vertical riser that diverts the water to the top of the tank and I would stipulate having a flush valve fitted at the bottom of the wet system to flush out the wet system a couple of times every year. This may by necessity entail plumbing a pipe extension to another area to release the water.
Another concern is the very low position of the outlet valve that supplies the pump. Regardless, if the water is to be plumbed to the cisterns and/or laundry and there will be more than one tank, it is best to set the tanks up as a settling system so that the pump draws clean water. This entails having all of the water diverted to one tank and the pump drawing decanted water from the last tank in line. You need to make sure that the water is diverted to the first tank's furthest end from the second tank.
Also be careful that the builder doesn't make you have a large (and more expensive) pump...you don't need one to fill a low flow end fixture like a cistern or washing machine. One of the smaller good quality Grundfos pumps is often ideal.
Also don't be fooled into accepting that you have to have an automatic mains water switching device like a Davey Rainbank...because you don't. You can also have a much cheaper and bullet proof manual device like a MainRain or an unpowered automatic device like the Acquasaver that operates by mains water hydraulic pressure.

Have a look at Sanden heat pump hotwater. Not cheap but you can run them from a solar panel or mains(only draw 1kw when heating). Reviews seem to be very good as well.…
