Rainfall Season


Here at RotoTank prospective buyers of our tanks often ask some recommendations when buying a tank. Of course, when we give advice, we need to understand the customers need more clearly and generally that conversation is a unique one. However, there are some general considerations when buying a tank.


Carefully consider what you intend to use your tank for. Tanks are manufactured for various purposes such as chemicals, sewage, and water. When buying a polyethylene tank three factors need to be considered: The chemical composition of the material to be stored therein; the weight of the material and the value. The combination of these three factors will enable your RotoTank™ technician to suggest the correct product.


Deciding about volume is not necessarily an easy one. Most chemical tanks are selected in a size that suits a production line or process.  Industrial sites often need large volumes but do not have enough space. The smaller footprint but larger size of the 20 000lt tanks and upwards makes them often ideal for factories.

Water tanks for rainwater harvesting are mostly in the 500lt to 5000lt range. Domestic yards often do not have much space requiring a distinctive design such as slim shaped tanks or square wall tanks. Make sure to check the diameters carefully when making your selection and leave enough room for expansion. Ask the local RotoTank™ branch manager for assistance in this regard. Our products are also on display at our branches so it might be worth your while to visit a branch and have a look.


Most people buying a water tank want an assurance that the tank has a black liner to prevent alae growth. RotoTank™ are all lined with ‘n black polyethylene liners which prevents it. However, some manufacturers supply tanks with lose fitting lids and open tank connectors. It is important to remember that these tanks often stand in open air storage for a while and may become home to creepy crawlies, dust, stormwater run-off, etc. When your tank is delivered, I am sure you will want a clean product and RotoTank provides just that. All our tanks are equipped with a secure fitting lid and sealed tank connectors to ensure that the tank arrives at your location


When ordering your tank make sure what your installation needs are. Your local RotoTank branch keeps most accessories to connect your tank, but, for special needs you may want to consult an installer or plumber. RotoTanks connectors are equipped with standard thread sizes and most irrigation supplies will easily fit thereto. We even provide a free leaf catcher for every water tank bought. Make sure that the manufacturer’s recommendations are followed to prevent a warranty dispute. Rigid piping can for example crack a tank due to expansion cycles and customers are often not told about small risks when installing a tank. At RotoTank your friendly adviser will give you ample installation tips.


One often does not think that a water tank may be a dangerous item. But consider for one moment what happens to five tons of water, or more, when a tank busts due to inferior quality. What if small children are nearby? At RotoTank™ our quality guarantee ensures a safe tank. Our water tanks are equipped with a child safe lid preventing small children from trying to climb inside for a splash and our tanks are manufactured with food grade material which is BPA / Bisphenol free will in no way compromise the liquid inside. Our customers can obtain a technical safety date sheet, especially in the case of chemical tanks. From this point of view, it would the expression ‘penny wise and pound foolish’ springs to mind.


While industrial applications are often not too concerned about appearance, the domestic sector normally wants the tank out of sight. Although you might want to boast about your RotoTank™, consider selecting a color which blends in with the color of your house or garden. Not all tanks and green, often a light brown or grey color, give more meaning to a setting in the dry season. Some manufacturers make special square tanks to fit narrow places or to be less obtrusive. RotoTank™ is the only company that up to now has made a ‘rock faced tank’ for aesthetic purposes. But, be warned, these tanks are normally quite pricy in the market.


Water, water everywhere! But every drop saved from your taps, shower and washing machine counts for nothing if you have a cracked drainpipe or leaky outside tap. Therefore, make sure your water saving plans are foregone by a proper maintenance check of all peripherals to the rainwater harvesting process. An innovative idea is to check your water bill regularly to make sure you’re being billed for several liters, which makes sense. If it doesn’t, investigate your property for leaks like some sort of water-saving superhero.


It’s not the cheap option but if you’re strapped for space rather than cash, this could be just the ticket for you. Many companies can hide your tank underground, leaving you without an eyesore in the middle of your carefully tended lawn. Your local RotoTank™ branch will have a full range of underground tanks. But be warned, not every installer is an expert at putting a tank underground. But that is a discussion for another time


Well, there you have it. There’s no time like the present to do your bit and recycle every precious drop.
