If you’re in need of more potable water for your property, here’s a quick guide on the ins and outs of a cistern tank installation for your property.

What is a Cistern Water Tank?

A cistern tank is primarily used for storing water in rural areas where potable water isn’t available through municipal services. They’re also used as an alternative to well water, which can experience issues with inconsistent yield or poor groundwater quality.

Why Consider a Cistern Water Tank?

If your well runs dry or doesn’t produce enough water to sustain your household, a cistern tank offers a reliable solution. They are also extremely popular for cottages with seasonal or occasional use, as they’re easy to maintain and hassle-free.

How to Determine the Right Size

When deciding on the size of your cistern tank, it’s essential to consider your daily water consumption. On average, cistern owners will consume approximately 110 litres of water daily per person. Using this calculation, a family of four, being conservative with their water usage, will need an average of 440 litres daily or 13,200 litres monthly. This estimation can help determine the appropriate size for your cistern tank to meet your needs efficiently.

Best Practices for Installing a Cistern Tank on Your Property


Site Assessment: Ensure the chosen location is easily accessible for maintenance and has a stable foundation to support the tank’s weight.

Capacity Planning: Evaluate the water needs based on the size and type of business to determine the appropriate tank size.

Regulatory Compliance: Adhere to local regulations and obtain necessary permits before installation.

Professional Installation: Engage experienced professionals to ensure proper installation, which includes appropriate connections to the building’s plumbing system and any necessary filtration systems.

Maintenance Plan: Establish a regular maintenance schedule to check for leaks, clean the tank, and ensure the system functions optimally.
