A Guide to Rainwater Tank Selection
What size tank should I buy?
At NTM we advise to install the largest tank possible that can fit in your available space. Naturally the size of the tank you select is dependent upon your intended usage. Whether you require a rainwater tank as the sole water source for your household or just a 'top up' tank for watering, NTM has the right tank for you.
We supply tanks from as small as 100 gallons to 57,000 gallons. NTM are also happy to custom build tanks to suit your specific requirements.
Poly or Steel?
All tanks manufactured and supplied by NTM are of very high quality and come complete with a 20 year warranty. Poly and Steel tanks both have their own benefits. At NTM we offer a selection of reputable brands to suit different circumstances.
Round Tank or Under eave?
Round tanks have a larger capacity and work out to be a more economical solution. Tanks from our under eave range offer clever, space saving solutions. Our tanks are designed to fit either underneath or along the side of your house or shed.
How much rain will it take to fill the tank?
The 'rule of thumb' calculation is as follows:
For every 1mm of rain (per square meter of surface area) 1 litre of water flows into the tank. In other words, If your roof is 100 square meters and you had a brief rain storm that dropped 1mm of rain on your roof, you would receive 1mm x 100 sqm = 100 litres of rainwater into your tank.
If a heavy storm came through and dropped 20mm of rain, 20mm (of rain) x 100 (square meters of roof area) = 2,000 litres of rainwater into your tank.
The benefits of drinking rainwater.
Collecting your own rainwater is not only environmentally friendly; rainwater that has been properly collected and stored is superior in taste and is wonderful to drink. Millions of households around Australia drink rainwater that has been collected and stored in rainwater tanks.
