The Benefits of Plastic Underground Water Tanks

Plastic or poly underground water tanks are becoming increasingly popular in South Africa for a number of reasons. Space considerations are one reason. Underground water tanks are also safe from vandals and they keep water cool. Where bush fires are a potential hazard, underground tanks are also well protected from fire. The article below elaborates on some more benefits of plastic or polyethylene underground water tanks.

Why Choose Polyethylene Underground Water Tanks?

With space increasingly at a premium one should not be deterred by the presence of bulky water tanks on your property. Burying water tanks underground is an increasingly popular method of benefiting from the storage capacity of rainwater tanks, without the space implications of above ground tanks. Water tanks can also help you extend the life of your garden during those long hot summer months, and can be used for other tasks around the home such as topping up your pool or washing your car on the weekend. Tanks are typically buried out of sight beneath a driveway or under your front or rear lawn, which also helps to keep the water cool!

Rainwater harvesting systems
 are one of a range of water efficiency measures aimed at minimising the water needs of individual households. The Australian Government also offers rainwater tank rebates to offset the initial set-up costs involved, which is a real incentive to start saving precious water and cash!

Plastic or polyethylene
 (poly) is a versatile material that is light and durable and also safe for human use. Underground tanks come in a variety of sizes, so choose based on your specific requirements. Avoid plastic tanks that are moulded with a seam, as this is often a weak point that results in the tank splitting.

Underground Tank Tips

Installing an underground water tank on your property requires careful planning and budgeting. Make sure you follow these guidelines:

  • Consult your local council regarding specific regulations for the installation of water tanks
  • Determine plumbing, installation and maintenance costs
  • Use an accredited plumber or green plumber for the installation
  • Choose your underground tank based on the amount of rainfall in your area, as well as the size of your roof
  • Ensure that your underground tank is certified to AS/NZS1546.1 standard, and is able to take a load
  • Plastic or poly underground tanks should also be constructed from ‘food grade’ materials, which make them safe for storing water for human use
  • Some plastic water tanks need to be installed on a concrete base, so check with your supplier before purchase as this will add to your costs
  • Make sure your installer checks for underground cables and sewer pipes as well as the water table in your area
