Litres Large round plastic Water Tanks are used on many applications for irrigation, municipal water supply to potable drinking water supply for shows and industrial chemical storage.  Enduramaxx manufacture a range of water tanks from 50 litres to 40,000 litres and low is a few applications for these larger water tanks.  We list out a few applications for these large plastic water tanks which Enduramaxx manufactures at our factory In Lincolnshire.    ## Large Plastic Rainwater Harvesting Tanks  Enduramaxx rainwater tanks are designed for both domestic and commercial applications and available up to 40,000 litres.  Our range of rainwater harvesting tanks, known as vertical storage tanks or water storage tanks, provide the water storage element for rainwater harvesting systems. Available in 40 sizes, up to 40,000 litres, our plastic water tanks allow rainwater to be stored and used at your convenience.  These tanks are a one-piece, rotationally moulded polyethene tank with no welds or seams. This also means there are minimal installation and assembly costs compared to traditional, sectional metal tanks, which can be quickly installed and be ready for filling within a couple of hours of delivery. These tanks are generally available from stock for quick delivery. View our Frequently Asked Questions For Our Large 20,000-litre plastic water tank [here.](https://enduramaxx.co.uk/news/20000-litre-water-tank-faqs/)   ## Large Plastic Potable Drinking Water Tanks  Our Large Plastic Potable Drinking Water Tanks are  [WRAS](https://www.wras.co.uk/) Approved for Potable Drinking Water storage up to 40,000 litres. These tanks are also food-grade for a stock of foodstuff and drinks with a smooth interior to allow easy cleaning. These tanks are UV stabilised so these can be sited outside for many years of use.   All our potable drinking water tanks are WRAS Approved in black, boat blue or natural DWI approved and meet the specific requirements of Regulation 31.   View the Frequently Asked Questions for our large 30,000-litre plastic water tank [here](https://enduramaxx.co.uk/news/30000-litre-water-tank-faqs/)  ## Large Plastic Tanks for Fertiliser Storage  These large plastic tanks for fertiliser storage are manufactured with thicker walls so can be used for tanks being used for water, we manufacture a heavy-duty range that can be used for fertiliser, molasses, and chemical storage.

These tanks have thicker walls to allow liquids up to 1.5 SG or 2 SG to be stored in the tanks. These tanks can be customised with outlets, PN16 flanges and pipework to suit project requirements. A range of side access, top hatch access and ladders are available.  Examples of chemicals that can be stored in plastic chemical storage tanks – [Sulphuric acid](https://enduramaxx.co.uk/product-tag/sulfuric-acid-tanks/), [Hydrochloric acid](https://enduramaxx.co.uk/product-tag/hydrochloric-acid-tanks/), [Hydrofluoric acid](https://enduramaxx.co.uk/tanks/chemical-storage-tanks/bulk-chemical-tanks/), Nitric acid, [Sodium hypochlorite](https://enduramaxx.co.uk/product-tag/sodium-hypochlorite-tanks/), [Sodium hydroxide](https://enduramaxx.co.uk/product-tag/sodium-hydroxide-tanks/), Ammonia solution, [Ferric sulphate and chloride](https://enduramaxx.co.uk/product-tag/ferric-chloride-tanks/), [Aluminium sulphate, ](https://enduramaxx.co.uk/product-tag/aluminium-sulphate-tanks/)[Polymers](https://enduramaxx.co.uk/tanks/specialist-tanks/polymer-make-up-dosing/), [PAC](https://enduramaxx.co.uk/tanks/specialist-tanks/polymer-make-up-dosing/). View our plastic chemical tank range [here](https://enduramaxx.co.uk/tanks/chemical-storage-tanks/)  ## Bunded Chemical Storage   Our bunded chemical tanks have been specifically designed with pollution control in mind. Selected for integral protection from leakage and overfilling.  These plastic bunded storage tanks are constructed using rotationally moulded mid-density polyethene.   Bunded chemical tanks contain a minimum 110% volume of the inner tank. Simply put, a bunded tank is a ‘tank within a tank’ that helps customers conform to current health and safety legislation.  ## Rotational Moulded Large Plastic Water Tanks  Rotational moulding involves a heated hollow mould that is filled with a shot weight of the polymer. The mould is then slowly rotated bi-rotationally causing the softened material to disperse and stick to the walls of the mould rotating at all times of the heating phase to avoid sagging or deformation.   The plastic takes the shape of the mould of the [storage tanks](https://enduramaxx.co.uk/tanks/enduramaxx-water-tanks/), and once it has completely formed, the mould is removed from the oven, the tank then cools and reveals the final product. The whole process takes anywhere from 20 minutes to more than 3 hours depending on the size of the tank and wall thickness.  View a short video of a rotational moulding oven in action below.    Enduramaxx moulds tanks in two locations with its head office in [Lincolnshire](https://www.google.com/maps/place/Enduramaxx+Limited/@52.7244198,-0.3449614,14.75z/data=!4m13!1m7!3m6!1s0x48781e39d0c947fb:0xa4a68618b3b28bd6!2sThe+Fen,+Baston,+Peterborough+PE6+9PT!3b1!8m2!3d52.7263943!4d-0.3350111!3m4!1s0x0:0x540d6992ae39b632!8m2!3d52.7195219!4d-0.3340262).  These rotational moulding ovens can manufacture vessels from 50 litres up to 40,000 litres and tanks as large as 4000mm in diameter by 3900mm tall.  For more details on our Large Round Plastic Water Tanks, chemical tanks or to discuss manufacturing a custom bunded tank, please contact the sales team or email [Sales@enduramaxx.co.uk](mailto:Sales@enduramaxx.co.uk).  [![Get in Touch -
