How to Check for the Best Site for Your New Inground Water Tank

Water storage is has become a big deal in Australia, with more people investing in one type of storage tank or another. They are an environmentally friendly way of harvesting rain water to use for different purposes including cleaning and watering the garden. They area also require very little maintenance and the entire installation pays for itself purely on the amount of water saved. In fact, some homes around Sydney have recorded a 50% saving on water since they installed a water tank. This has led to an increase in water tank providers within the different cities, providing different types of water tanks including concrete and plastic reservoir.
When it comes to deciding what sort of tank you want for your home, your options lie between an above ground and an in-ground water tank. In-ground tanks come with less intrusion on the aesthetics of your home, and more importantly can be installed in a relatively small space since they will be buried in the ground. When choosing where to install your new in-ground reservoir, here are some of the things you should consider:


Ground elevation is a huge contributor to choosing a place to set up your tank. This is because it determines how much work will have to be done before the install is complete, with regard to the excavations that are required.An even ground more often than not leads to a seamless and easy installation. On the other hand, when the ground is uneven, the excavation work that is required doubles. This is because you cannot install an in-ground water tank on uneven ground. If your preferred location is a hill, you will obviously have to put in work to settle the ground, which might prove expensive. It would be cheaper to avoid such inconveniences if you can, by choosing a flat, easy to work with location. This will also determine how easy it is to construct the cover for your tank, regardless of whether it is made of plastic or from concrete.

Soil structure

When working with in-ground tanks, the soil composition matters a lot. It should be easy enough to excavate, while remaining firm enough to hold the tank. The idea here is to avoid loose soil which as easy as it is to dig out, will also be easily washed away by water or blown away by the wind. It also makes it hard for the tank to remain in one place, by being easily displaced during the changes in water level in the tank. This movement could cause damage to our tank over time, and could even lead to leaks.
Avoid choosing a location where the soil is made up of rocks and other debris. To begin with, the rocks will make the excavation process expensive and lengthy, with specialised equipment being required to remove particularly large rocks. You will also be required to line the hole either with concrete or another type of soil, then compact it, to reduce chances of damage to the tank. Sharp rocks are a hazard that could result in a leak, which is expensive to repair.


The ideal situation is to have the tank installed as close to your home as possible. Proximity to your home is more than just about the distance; it factors in on the cost. When you tank is installed a distance from your home, you will be forced to spend more on plumbing materials to get the water to the home. The length of piping needed is increased which of course means you will spend more on plumbing to send water to the home, and to drain water from your roof to the water tank. You will also have to pay the plumber more for work done. In some instances, you might even be required to invest in a more expensive water pump with more power, since the water cannot make its way to your home on a smaller one.

Available space

People with smaller compounds have to factor this in when choosing a site for their in-ground tank. This is because the land has to be utilised for other things other than the tank. Some people have successfully installed a water tank, and then built another structure on top of it, such as a driveway or even a garden shed. This means that you ave to make sure the concrete cover for your underground water tank is strong enough to withstand certain weights. This is an expensive endeavour since you will have to spend more on construction material. Unfortunately, if your compound is tiny, you may not have an option other than investing in such an undertaking.
