Water Storage Tanks FAQs

What type of water tank do I need?

At Tanks.ie, we stock a range of different water tanks. From rainwater harvesting to wastewater treatment, there are water tanks designed for all types of water storage. The type of water tank you need will depend on what you plan to use it for.

If you are storing drinking water, you will need a potable water tank, like these GRP tanks. They are suitable for storing clean water that is fit for human consumption, prepping food and cleaning dishes. They meet government approved standards and regulations for the safe storage of drinking water. Non-potable water tanks store water that can be used for other purposes like flushing toilets and watering plants but is not safe for human consumption.

If you’re storing hazardous materials or liquids, check out our range of IBCs (Intermediate Bulk Containers) or if you’re working in the agricultural, farming or horticulture sector, you may want to have a look at our agricultural water tanks that are built to withstand the changeable outdoor environment. Our rainwater harvesting tanks are great for collecting and storing rainwater, that can then be used to flush your toilets and wash your clothes.

We have many more types of water tanks available at Tanks.ie. If you’d like any help and advice choosing your water tank, don’t hesitate to contact our friendly team.

How long should a water storage tank last?

There are many factors that can affect how long a water tank should last:

  • Usage

The purer the water you’re storing in your tank, the longer your tank is likely to last. For example, if you’re storing salt water, there is a much higher risk of corrosion and damage to the tank. Clean water is much less likely to damage your tank.

  • Materials

Most water tanks will be made from either plastic or metal. Plastic tanks are non-biodegradable so it shouldn’t break down over time. For this reason, you should use a specialist waste disposal company at the end of your tank’s life. A good quality polymer plastic water tank should last between ten and twenty years. Metal water tanks are usually made from steel which can be melted down and recycled at the end of its life. A steel tank should last over 30 years.

  • Location

Where your tank is located could also affect its lifespan. If your water tank is stood in water, it could damage it, so try to ensure your tank is placed on a solid foundation. The UV treatment on plastic tanks can also be reduced if exposed to long hours of direct sunlight.

How much does it cost to install a water storage tank?

Water tank installation and replacement costs can vary greatly based on several factors. 

First, you’ll want to consider the cost of the tank itself. The bigger the tank, the bigger the price tag. The material the tank is made of will also impact the cost, with metal water tanks costing slightly more than plastic ones.

When it comes to the installation, underground water tanks generally cost more to install than above ground water tanks. Underground water tanks need an excavation crew to dig out the area where the tank will go, so you will need to factor in the cost of labour to do this. If you are installing a cold-water storage tank in an attic, the biggest challenge is getting the tank inside the loft through the loft hatch and removing the old tank. Ease and accessibility will play an enormous factor in the final cost.

Finally, you will need to consider the cost of a plumber to connect the pipes. If you’re wanting any additional add-ons for your water tank, such as booster pumps to increase the water pressure, there may be additional costs to consider.

We recommend consulting your local council and homeowners' association to ensure that your water tank installation meets all the required guidelines.

How long do cold water storage tanks last?

Typically, well-maintained cold water storage tanks crafted from durable materials like polyethylene can last anywhere from 20 to 30 years. The high-quality construction of the tanks sold at Tanks.ie contributes significantly to their longevity, with resistance to corrosion and wear-and-tear ensuring reliable performance over an extended period.

Your proactive involvement in regular maintenance plays a crucial role in determining the lifespan of the tank. Timely inspections for signs of damage, leaks, or structural issues can significantly prolong the tank's functionality. Regularly checking fittings, valves, and the integrity of the tank structure is essential to catch and address potential issues before they escalate.

Exposure to extreme temperatures, UV radiation, or harsh chemicals can accelerate wear. Proper installation and placement in a sheltered, well-ventilated area contribute to the tank's overall resilience.

Do I need to insulate my cold-water storage tanks?

Insulating your cold-water storage tank is a wise decision with several benefits. The primary reason to insulate is to prevent heat loss from the water inside the tank. During colder seasons, especially in the Irish climate, uninsulated tanks can experience a drop in temperature, potentially leading to issues like freezing. Insulating your cold-water storage tank helps to maintain a more stable water temperature, reducing the risk of freezing and ensuring a reliable water supply.

By minimising heat loss, you can reduce the energy required to heat the water, which is particularly important if you have a water heating system connected to the tank. This energy-saving aspect not only promotes sustainability but also reflects positively on your utility bills, providing a cost-effective solution in the long run. Regulations often recommend or mandate specific insulation measures to enhance energy efficiency and prevent common issues associated with cold water storage. Ensuring your tank meets these regulations not only keeps you in compliance but also guarantees that your water system operates efficiently and safely.

 

What’s a potable water tank?

Water tanks can be classified as ‘potable’ and ‘non potable’. If you are storing clean water for human consumption, whether it be for drinking, prepping food or cleaning dishes etc, then a potable water tank is what you are after. All potable tanks must conform to the WRAS (Water Regulations Advisory Scheme) so that the liquid is safe for human consumption.

Non-potable tanks are for the safe storage of non-drinking water or for ‘not suitable’ for human consumption, in many different environments and applications. Non-potable tanks can be used in applications like rainwater harvesting, irrigation, agriculture & horticulture and commercial purposes where mains water is not available.

The difference in classification between the two comes from the materials used during the manufacturing process, specifically the type of plastic used to line the inside of the tank which comes into contact with the contained water. Non potable tanks are more porous, making it easier for the bacteria to grow and can sometimes let off gases which can contaminate the water. The WRAS approved material lines the inside of the tank, making the tank fit for human consumption, either ingested or used on the skin.

What is the difference between Potable and Non-Potable water tanks?

potable water tank is suitable for storing drinking water and must adhere to specific government regulations. A non-potable water tank stores water that can be used for other purposes like flushing toilets and watering plants but is not safe for human consumption.

All potable water tanks, like these GRP tanks, must be submitted to the WRAS for testing, approval and accreditation and be approved in line with the Water Supply (Water Fittings) Regulations 1999. Potable water tanks are usually constructed from food-grade polyethene and finished with a smooth interior to protect against bacteria growth. Our potable water tanks come in a wide range of capacities, from 4 litre to 250,000 litre.

Non-potable tanks store water that can be used for plumbing purposes, such as flushing the toilet and in washing machines, as well as for gardening. They are often used in industrial and commercial premises, horticultural and market garden applications, agricultural irrigation and civil engineering situations where mains water is not available. In fact, non-potable water tanks are suitable for any application where the water or liquid stored will not be consumed by humans or animals.

 

 

What materials are the plastic tanks manufactured from?

Plastic water tanks can be made of lots of different materials, however the majority of tanks we offer are made from either a medium density polyethylene (MDPE) or a high density polyethylene.

What outlet do I require?

The majority of our water tanks come with an outlet as standard. We can offer a range of water tanks where the tanks can either ‘Drilled’ or ‘Undrilled’. ‘Drilled’ meaning allowing water to escape from the tank via the outlet, whereas ‘Undrilled’ is when the outlet will remain sealed, preventing liquid from coming out and ensuring the contents of the tank is only touching plastic.

If the position of the outlet is required in an alternative position to the standard one offered or extra to the one positioned, we can offer a plastic Fusion socket. This can be welded anywhere on the tank using a drawing supplied by us, positions marked out by you, then fitted by the manufacturer.   

Plain tanks (with no outlets) can also be offered.

If you require a plastic fusion socket or a plain tank, then please contact our Customer Service Team, who will be happy to help with your requirements.

Tap or hose tail kits, what’s the difference and when would I need one?

We offer a range of tap kits, each displaying the size of the hosetail and the outlet size the kit will suit. Tap Kit 5 (TPK5) is the best solution if you require a garden hose to be fitted. Our range of Hosetail kits allows you to attach a hose or pipe to the tank, leak-free. They are designed for continuous flow and come in varying sizes depending on the outlet.

All our tap kits come with a Jubilee clip and PDFE tape for that secure fit.

What’s a standard hose pipe size?

UK hose pipe diameters range from ½” to ¾” inch diameters. The majority of standard size garden hoses are 3/4” BSP, however we do offer accessories for the ½” hose, if required.

Baffled Water tanks, what are they and when are they recommended?

Baffled water tanks are tanks with an intergral wall system, which is primarily designed to strengthen and support the structure of the tank, when the tank is full of water.

Due to the structure of the baffles they can also be used for transporting water. The Baffles distrupt the movement of water, from surging from one side to the other. However, if you are transporting water, water tanks can be extremely hazardous when transporting large volumes of water. Please make sure the water tanks are installed and secured correctly, by a suitable qualified person before transportation. Baffled water tanks are an ideal solutions for car valeters, window cleaners or anyone who has to transport liquids using plastic water storage tanks and containers.
