Plastic Tank FAQs
Plastic fuel tanks typically have a 10-15 year lifespan, supported by a 10-year warranty in the case of many major fuel and oil tank manufacturers. The lifespan of these containers can be affected by a wide number of factors, including the design (bunded tanks tend to outlast single skin tanks), conditions, and maintenance. Regularly maintained plastic fuel tanks can last for up to 20 years.
For those looking for a tank set to last over the 20-year mark, steel fuel tanks may be a safer bet. Though slightly pricier, steel tanks are generally less prone to age and environmental damage.
The price of a plastic fuel tank is highly dependent on its size, design, intended function, features, and brand. Whilst single skin tanks tend to be the least expensive plastic offering on the market, some with enhanced safety features may be listed at a higher price point than a small bunded plastic fuel tank.
Generally, single skin tanks are less expensive than bunded tanks, with the price increasing with size or capacity. RPM fuel’s range of plastic fuel storage tanks ranges from approximately £900 to £5000 in accordance with the above factors.
Both plastic and steel fuel tanks can be used to safely store a variety of fuel types.
Safe fuel storage is reliant on both a high-quality tank, and its correct installation, use, and maintenance. A well designed, well maintained, and correctly placed plastic tank can last for up to 20 years without incident. It is, however, important to note, that single skin plastic fuel tanks are more likely to suffer damage as a result of age, a lack of maintenance, or exposure. If left unnoticed, this damage may lead to leaks, causing significant environmental damage. For this reason, it is important to consult an OFTEC registered technician when first installing a fuel tank of any sort, and secondly, inspect your tank for signs of damage on a regular basis.
Plastic tanks, particularly when located outdoors, are subject to a number of harsh conditions that may cause strain and cracking – especially in the case of single skin plastic tanks.
Tanks subject to extreme temperature changes, incorrect installation, low levels of maintenance, continued exposure to sunlight, and heavy rain are particularly subject to damage, much of which cannot be repaired after it has occurred.
- Uneven bases – cause an uneven distribution of pressure throughout the tank, which may lead to cracking, especially when the tank is full.
- Incorrectly closed caps and lids – tanks subject to open lids can intake a high amount of rainwater if conditions are right. Water contamination can cause bacterial growth, particularly where diesel is being stored.
- Sunlight – single skinned plastic tanks, particularly those not composed of materials designed to withstand UV exposure may warp, whiten, and weaken when exposed to direct sunlight on a regular basis.
- Temperature changes – cold weather, particularly heavy snowfall, can cause plastic to become brittle and break.
In order to avoid these common causes of damage, it is important to ensure the correct installation of your tank, and to inspect it for damage, or signs of strain on a regular basis.
The lifespan of diesel in storage, like any fuel, is highly dependent on the conditions it is stored in. Diesel stored in an allocated plastic container that receives correct maintenance will generally last for between six and twelve months, so long as it is kept relatively cool, and completely dry – that is, water is not allowed to leak into the container. In order to extend diesel’s lifespan past this in storage, stabilisers are generally used.
The information above applies to diesel fuel only, not biodiesel or blends.
Dedicated diesel fuel storage units, both steel and plastic, can be found in the diesel section of RPM Fuels’ website.
The size of diesel tank required to adequately meet your fuelling needs depends on a number of factors, including the fuel efficiency of the vehicles or machinery to be powered, the frequency of use and refuelling, and how often you would like to refill the tank itself. Clients looking to avoid frequent refuelling, or looking to take advantage of current and future diesel price fluctuations may consider purchasing a larger tank for further storage.
For example, a tank with a capacity between 1000 and 1500 litres would be most suitable for those fuelling farm vehicles covering 1-20 acres of agricultural land, those fuelling between 1 and 10 light commercial vehicles, or between 1 and 2 heavy vehicles, such as HGVs.
Regardless of storage method, all fuels stored over a long period of time will degrade. This is particularly true of diesel, which can be stored from anywhere between 3 and 12 months, sometimes longer when the correct additives and preservatives are added. Biodiesel fuels are less predictable than diesel fuels, with five main factors influencing the amount of time they stay fresh for in storage – microbe contamination, light, storage temperature, oxygen exposure, and feedstock.
Microbial contamination is a prevalent issue in biodiesel storage, as biodiesel provides an excellent environment for microbes to feed. Microbes may be introduced to fuel any time it is contaminated by water, meaning it’s important to keep your storage tank secure, and your fuel dry.
In addition to this, it’s important to avoid unnecessary oxygen exposure to prevent a loss of oxidative stability.
Waste oil tanks allow for the on-site storage of contaminated or waste oil prior to removal and disposal. Though typically smaller than oil or fuel storage tanks, waste oil tanks are available in both bunded and single skin formats. RPM Fuels currently stock a large range of plastic bunded waste oil tanks, manufactured by Harlequin.
After storage in a waste oil tank, waste oil may be disposed of in multiple ways, including sending it to a licensed disposal site, such as a garage, or waste disposal facility permitted to handle oil and fuels.
All water tanks sold on a regulated basis in the UK today are safe – so long as they are installed and maintained correctly.
Before the introduction of modern regulations, many ‘potable’ water tanks were constructed of unsuitable materials such as galvanised iron, which could result in the contamination of water over time. Now, tanks are most commonly constructed from a high or medium density polyethylene or plastic – making water stored within them safe for consumption.
Further regulations put in place to ensure the safety of water tanks on the market today include size guidelines (water tanks too large for the amount of water consumed do not allow for frequent replenishment with fresh water), and a general requirement for close-fitting covers, tight, securely fastening lids, screened vents, and insulation in any new designs.
Potable water storage tanks are used to store potable water – water that is safe for human consumption. These tanks tend to be constructed of a food-grade, medium density polyethylene, and approximately 250 litres in capacity on average – but can range from anywhere between 5 to 30,000 litres.
Non potable water storage tanks, on the other hand, are used to store water which may no be used for human consumption. They are commonly installed on agricultural and commercial properties. It’s important to note that in general, the majority of plastic water tanks on the market are non potable due to the porous nature of many commonly used plastics – so look out for potable or non potable product labels or descriptions before selecting your storage tank.
