At this most wonderful time of the year an underground storage tank may not be top of your Christmas list, but we hope by the time you’ve reached the end of this blog post your mind will be well and truly changed.

Above ground water tanks are the more conventional water tank type, but have you considered an underground water tanks as an alternative? They’re surprisingly versatile and provide some genuine advantages compared to standard water tanks.

An underground water tank has a wide range of uses and applications

• Store water harvested from rainwater – an increasingly popular method for gardeners and horticulturalists
• Store municipal water from a range of sources for household use
• Can be used as a water reservoir for water irrigation systems – useful for large areas requiring regular watering such as race courses and sports fields
• Emergency supplies of water can be stored safely underground for a long period
• Emergency water supply for fire fighting
• Water for livestock

There’s a few drawbacks with underground water tanks

• Underground water storage tanks can be pricier than above-ground tanks as they’re more durable and the construction technique is more specialised
• The installation of underground water tanks can be a more costly and difficult process compared to installing above-ground water tanks
• A pump is needed to extract water from underground storage tanks, while above ground tanks may only require gravity to provide enough pressure, especially if a water tank stand is deployed.

Some very good reasons for getting an underground water tank

• If space is limited, especially in private homes, underground water tanks can be located under driveways or lawns
• Above-ground water tanks can be an eyesore whereas underground water tanks can be neatly hidden away from view
• Water stored underground is safe from potential vandals and tampering
• Underground tanks offer protection from fires and other natural disasters
• If you want to locate your underground tank on a farm or nature reserve, underground tanks offer protection from potential damage by animals.
