Tips For Buying A Rain Water Storage Tank

For homeowners and agricultural customers alike, the purchase of a water tank to store rain water makes good economic sense. Rather than to pay for commercial or governmental provision of water supplies, the home or business owner who installs a high quality rain water storage tank and pump has only minimal ongoing expenses.

Above ground rain water storage tank options

Determining the use that will be made of the collected liquid is an important consideration in choosing storage tanks. The rainwater can be used for household consumption, watering lawns and gardens, or for other purposes. The end use will drive the decision about the materials used in the construction of the tanks, as well as the level of filters which will be required. You will also need to consider the terrain where the tank will be located and distance from the end-use point.

Above ground tanks made of polyethylene are available in a number of sizes and brand names. The Sydney tank firm has more than one thousand units in inventory. The current brands which are carried by the firm include:

* ET tanks* RP tanks* BR tanks* TT Slimline tanks* DP tanks* Underdeck tanks* Colorbond tanks* MO tanks

Above ground rain water storage tank capacity ranges from 500 liters to 5000 liters. The diameter of the unit also has various options in order to best fit in the available space. The shape of the container is available in slim, round or other variations.

A container which sits in plain view may interfere with the usability of the space, Some customers will prefer to place the equipment in a closed building which can also be used for other purposes.

Under ground rain water storage tank choices

Underground tanks are less visible, which is important when you are looking for aesthetic appeal of your home or business. Tanks which are suitable for collecting rainwater and storing it underground can be constructed of polyethylene or concrete. Underground models have very little of the equipment which is visible, and landscaping can be arranged so that the lawn and garden space is still functional for other purposes than containers to store rainfall. In most instances, the purpose for storing rainwater is to be able to use it in a relatively short period, such as until the next rainfall.


Some of the underground storage models which are available include DP flat poly tanks; a TM donut poly and a TM bagel poly. There is also GT Li Lo Poly models. Concrete storage tanks are available from SWT and EC. For these tanks the capacity ranges from 380 liters to 11,500 liters. Concrete tanks tend to be available in much larger capacity.

Rain water storage tank and drainage pumps

Pumping the clean H2O to the end-use location requires a pump. The size of the pump will depend upon factors such as the distance from the container to the end use, the terrain over which the stored supplies are moved, and the pressure or force of the liquid needed at the end-use point. For example, a garden irrigation system which uses a drip feed may require a different sized pump than a garden watering system which relies on sprinklers.

Consideration must also be given to the type of debris which may be present in the pumping process. Periodically, a rain water storage tank may need to be emptied and cleaned, which requires another type of pump configuration.

Some of the pump options include Basic pump systems; garden pump systems and drainage systems. The Basix pump brands which are available include:

* Davey Rainbank* Onga WaterSwitch

The company carries Davey Pressure Pumps and Onga Pressure Pumps in the Garden Watering Systems category. Zenit Drainage pumps are best suited for removing dirty liquid residue from the container, Zenitt also carries a selection of drainage pumps for clean liquid pumping. Each of the listed pumping equipment comes with a two-year warranty.


There are a few accessories which are needed, to go along with a rain water storage tank system. The First Flush Device, Leaf Divertor, Super Head, Hose Kit, Depth Gauge and Pump Cover each help to ensure that the tanks, pumps, and hoses are functioning at peak efficiency.

Working with a customer service representative is the best way to determine the type of system which is best for your needs. The Sydney firm’s location at Warwick Farm is available to speak with customers looking to capture rainwater for future use. Many of the options in the product lines are available at prices lower than the Manufacturers’ Suggested Retail Price (MSRP).
