What is a potable water tank?

A potable water tank is installed for the safe storage of drinking water. They require specific internal liners that ensure the purity of the contents.

From small capacity tanks starting at 1,000 L, to large commercial sized tanks up to 250,000 L, our robust range of long-lasting, potable water tanks are the perfect solution to help conserve our water resources and reduce your water bills.

Example applications

  • homes
  • gardens
  • offices
  • industrial sites
  • schools
  • commercial sites

If you would like to conserve water for non-potable uses, please visit our rainwater harvester page for solution which meets your needs.

How does a potable water tank work?

The average person in Ireland uses approximately 142 L of water daily. This water is treated and distributed by expensive municipal systems, and yet only a small fraction of it is used for appliances that actually require potable water.

The scale of water waste is huge - and so is the opportunity it gives us to conserve our precious drinking water supplies.

Clean water storage

Manufactured from robust GRP, our Rewatec potable water tanks hold clean water until there is demand for it generated by a single dwelling or a commercial business. When you need access to water, whether it be for drinking or bathing for example, our potable water storage tanks will provide you with instant and clean water.

Our Rewatec potable water tanks can be installed above or below ground. All 22 sizes conform to WRAS (Water Regulations Approval Scheme) standards and regulations for the safe storage of drinking water.

Potable water tank maintenance

Protect your investment in your Rewatec potable water tank by having it regularly inspected by Premier Tech.
