Installing a water tank the right way helps protect your tank, improve water flow and make your water storage system easier to use. Whether you are setting up a small rainwater tank at home or planning a large-capacity tank for a farm, rural property or commercial site, good preparation is essential.
Great Northern Tanks supplies water tanks and water storage products for homes, farms, businesses and remote properties across Australia. This guide explains the main steps to consider before installation, including site planning, base preparation, delivery access, plumbing, pumps, filtration and ongoing maintenance.
A water tank is a long-term investment. If it is installed on the wrong base, placed in a poor location or connected incorrectly, it may not perform as well as it should.
Good installation helps:
Before installing any tank, always check the product requirements, local regulations and site conditions. Larger tanks may also need professional installation or site-specific advice.
The first step is choosing a suitable location. Your tank should be close enough to your water source, such as roof gutters, downpipes, sheds or water collection points. It should also be easy to access for delivery, maintenance and future repairs.
When choosing a tank location, consider:
For homes, slimline tanks are often installed beside a house, garage or fence. Round poly tanks are better suited to open areas. Steel panel tanks and large-capacity tanks need more space and careful site planning.
A stable base is one of the most important parts of water tank installation. The tank base must be level, firm and able to support the full weight of the tank when it is filled with water.
Water is heavy. A full tank can place a lot of pressure on the ground beneath it. If the base is uneven or unstable, the tank may shift, lean or become damaged over time.
Common tank base options include:
The right base depends on the tank type, tank size, soil conditions and site requirements. Large steel panel tanks may need more detailed base preparation than smaller household tanks.
The base should usually be wider than the tank footprint. It should also be free from sharp objects, roots, rocks and debris that may damage the tank floor.
Before your tank arrives, check that there is enough access for delivery and installation.
For smaller poly tanks, access may be simple. For larger water tanks, especially steel panel tanks, delivery access needs more planning. Rural and remote properties may also need to consider road conditions, gates, turning space and equipment access.
Check:
If the site is hard to access, discuss this before delivery. Planning early helps avoid delays and makes installation smoother.
For rainwater tanks, the tank must be connected to a roof catchment system. Water usually flows from the roof into gutters, then through downpipes into the tank inlet.
A well-designed inlet setup helps direct clean water into the tank and reduce debris.
Helpful components may include:
Keeping leaves, dirt and insects out of the tank helps protect water quality. This is especially important if the tank water will be used inside the home or for drinking water purposes.
Every water tank needs an overflow point. When the tank is full, excess water must be directed away safely.
The overflow should move water away from the tank base, buildings, footings and areas that may become waterlogged. Poor overflow planning can cause erosion, soft ground or damage around the tank.
Overflow water may be directed to:
Always check local requirements before connecting overflow water to stormwater or drainage systems.
Depending on how you plan to use the water, your tank may need a pump, pressure tank, filtration system or pipework.
A pump helps move water from the tank to taps, gardens, troughs, sheds or buildings. Filtration may be useful if the water is used for household purposes. Water monitoring can also help you track levels, especially on farms, remote properties and commercial sites.
Common system add-ons include:
The right setup depends on your property, water use and tank location. For example, a rural property may need pipework to troughs, while a home may need a pump for garden taps or household use.
Some smaller tanks may be simple to place and connect. Larger tanks, steel panel tanks and commercial water storage systems often need professional support.
Professional installation may be recommended when:
Using the right installer can help reduce mistakes and make sure the system is set up correctly from the start.
Once the tank is installed, check the full system before regular use.
Look for:
It is also a good idea to inspect the system after heavy rain, strong wind or the first full fill. This helps identify any issues early.
Different properties need different installation planning.
For homes, the main focus is usually space, gutters, downpipes, pumps and garden or household use. Slimline tanks are helpful for narrow spaces, while round tanks work well in open areas.
For farms and rural properties, installation may need to consider livestock access, irrigation, pipe runs, troughs, pumps and backup supply. Larger tanks may also be needed to improve water security during dry periods.
For commercial and industrial sites, installation may involve higher water demand, safety requirements, site access, filtration, monitoring and connection to existing infrastructure.
After your water tank is installed, regular care helps keep the system working well.
Simple maintenance tasks include:
Good maintenance protects the tank, supports water quality and helps avoid avoidable repairs.
A successful water tank installation starts with good planning. The right tank, base, location, fittings and accessories can make your water storage system easier to use and maintain.
