Save Space, Water, and Money with Underground Water Tanks

Underground water tanks have become ideal, especially for urban residents who do not have enough space to install above-ground water tanks. Harvesting rainwater in underground water tanks also saves you money as you reduce the amount of water you take from the utility company. 

Underground water tanks save you space since you can use the area for other purposes, such as a driveway, especially if the tank is covered with a concrete slab. Rainwater harvested in underground water tanks can be used to irrigate a kitchen vegetable garden. This will reduce the amount of money you spend buying vegetables for your home. The water is also used to water grass and flowers in the compound.


Benefits of Underground Water tanks

· Saves space as you can install one under a lawn or driveway

· Hidden from view as they are underground

· Water is safe as it cannot be vandalized and tampered with especially in areas where civil unrest is common

· Water tanks that are placed underground have protection from natural disasters and fire, unlike those that are above ground.

Types of Underground Water tanks

There are two types of water tanks that are ideal for underground installation.

1. Poly Tanks

Plastic underground tanks are manufactured with food-grade polyethylene that is UV stabilized. Their design is specially made for strength, and they are available in various sizes and shapes. The plastic is so strong that it endures the weight of a car above ground. Also, you do not need to dig a very deep trench to install them as you can install them shallowly.

2. Concrete Tanks

You can pour a concrete on-site or have them precast and then reinforce them with concrete for maximum stability and strength. They are unaffected by tree roots, corrosion, or rust. Concrete tanks are strong enough to the point of installing other structures above them.

Considerations when installing an underground water tank

· Available Space on the Property

When installing an underground water tank, you will excavate the ground to create room for the tank. Locate an area where the excavation will not affect operations in the compound and where it will not interfere with other installations such as electricity cables or the sewer system.

· Plumbing

Locate the water tank near your water pipes to reduce costs. The tank should also be in a location where it receives rainwater efficiently without contamination. 

· Purpose of the Water

The purpose of the water in the tank is another important consideration. If the water is for watering the garden, place it close to the garden, and if it is for house use, place the tank near the house.

· Type of Soil 

Underground water tanks should be installed in areas where the soil drains well and where underground water levels are low. Avoid installing underground water tanks on soils that retain water for a long time.In conclusion, with the reducing rainfall in Australia, we need to conserve as much rainwater as possible. The use of underground water tanks is encouraged as they will store large amounts of water free of contamination. There is no exposure to elements such as sunlight that may affect the quality of water. Consult a professional when installing this type of water tank as it requires professional skills to install one.
