The size of your tank depends on a number of factors such as the average rainfall where you live, the size of your roof or catchment area and the number of uses you have for your tank. Renew’s “Tankulator” can help you work out the best tank size for your needs. Once you know your ideal tank size, either browse our range or call to speak to one of our experienced staff members
Two of the main factors that influence how quickly your tank will fill are the size of your roof and the amount of rain that falls in your area. As a general guide, every 1mm of water that falls on 1m2 of catchment space will yield 1 litre of water.
An important part of calculating how fast your tank will empty is the number of uses for your stored rainwater and how often or extensively they are utilised. For example, a rainwater tank used solely for flushing toilets in a two-toilet house using 20 litres per flush, will use around 150 litres per day. A household that uses stored rainwater solely for watering a large garden will have increased usage in the summer months (due to a combination of higher evaporation and lower rainfall) but will require approximately 10 litres per square metre of garden per week.
Our wide range of tanks has plenty of options to suit the many different scenarios for tank placement. We have tanks as low as 1370mm, which are ideal to place under a window, as high as 2240mm and from 650mm wide to 3620mm wide. The tank dimensions are located on each individual tank page, but our experienced staff can quickly answer your queries when you call. If you’re still struggling to fit a tank into your space with our round and slimline range, why not use an underground or under-deck tank and reclaim your yard?
Our smallest tank by litreage is the 501lt round tank having 700mm in diameter and 1370mm in height. However, if you’re after a tank that fits into a short space, our under-deck tanks are as low as 700mm whilst providing a whopping 1800lt capacity.
Our largest tank is the 25,000lt round tank at 2760mm high and 3620mm in diameter. However, if you’re after larger capacity water storage it’s common to see several 25000lt tanks joined together to provide over 100,000 litres of water.
Yes we do! As you can imagine, not many of our customers have a vehicle big enough to load a tank on the back so we have our very own fleet of utes, vans, trucks and trailers to bring the tank to your door. Make sure that you tell our staff your location has a difficult access so we can send the right vehicle to make sure we can get the tank to you. See our Delivery page for more information.
Our pricing structure includes delivery in the price of the tank. In locations outside of NSW or remote areas, we have a secondary pricing structure to cover the increased delivery costs. We endeavour to keep these costs to a minimum by sharing loads to these areas so please contact the office and speak to our staff who can provide you with a quote for your location. See our Delivery Information page
Poly Water Tanks’ specific expertise lies in the manufacturing of water tanks and we hand over the process of installation to licenced plumbers so that we can get the tanks to you quickly.
Because we deliver to a large portion of the Australian east coast, we don’t have relationships with plumbers in all delivery areas. Your best option is to contact your local plumber who can follow our installation guidelines if required.
All of our tanks come with a 25mm or 40mm outlet (depending on the size of the tank), a 90mm overflow and a leaf strainer. For fittings outside of the abovementioned standards, we stock a variety of non-standard brass outlets, PVC overflows, spigots, strainers and strainer lids. See our Accessories page to see many of the available options - if it's not there, we can order any custom fittings when you place your order.
Basic cleaning of your tank involves removing leaves and debris from the inlet strainer and a general visual inspection to check for cracks or leaks. For a more detailed explanation of how to clean your tank, what's required when using your tank for drinking water and how to maintain your pump, please see our general maintenance article.
