Rainwater tank pumps and tanks are typically used to shop rainwater for later use. Water is a finite resource and should be treated with care. While a rainy day invites you to cosy up on the couch with a good book or watch your favourite movie, there are not many consolations available. However, if you can add another to that list by acknowledging that water supply is a problem around the world, and we can help by installing a water tank to capture rainwater, you’ll be doing your part to protect the environment by reducing your carbon footprint. By installing a rainwater tank pump, you reduce your need for tap water and the amount of rainwater that runs off into the rivers and oceans, and as an added bonus, you reduce your water bill in the long run.
Most people still tend to think of rainwater tanks as big, round and ugly. But like the rest of the world, these tanks have evolved, and there are now many shapes and sizes for you to choose from. In this blog, we will give you a guide to buying a rainwater tank.
Indoor and outdoor use
Before you get a rainwater tank, you should be clear about why you need a rainwater tank and how you plan to use the water. As for outdoor use, you can use it to water your garden, maintain your car, and more. There are many tasks that you can do if you have a rainwater tank installed on your property. In this way, you can save a lot of costs related to water consumption and even more if you choose to use the rainwater for indoor use, such as toilets, hot water systems and washing machines, but for this you will need an experienced plumber to connect the tank to the main line.
What size tank do I need?
Tank size refers to capacity and depends mainly on the size of your household and yard. If you do not have room for a larger tank, slimline tanks are best for narrow spaces and round, squat tanks that can easily fit under a patio.
Aside from your water needs, your roof area and annual rainfall in mm will also determine the size of tank you should choose. If you search online for a water tank, you will find that most manufacturers help users with a calculator. You can also contact your water authority for additional help.
Factors to consider before buying a rainwater tank
Materials
You need to carefully choose the material your tank is made of. Here is an overview of the different types of tanks made of different materials.
Metal tanks: some types of tanks are made of flat-rolled metal that is either galvanised or coated. These types of water tanks have an inner liner made of plastic, which is mainly used to extend the life of the tank and preserve the water inside.
Polyethylene (plastic) tanks: these tanks are popular mainly because they are cheap and durable. Since rust is not an issue with plastic tanks, they are ideal for people who live near the ocean. Other synthetic materials such as PVC and geotextile are used for water bladder storage.
Fibreglass tanks: tanks made of fibreglass are widely known and popular because they are rustproof, chemical resistant, and can withstand extreme temperatures. If you are looking for economical options, you should not opt for these tanks. It should be noted that they are suitable only for above-ground installation.
Concrete tanks: these are commonly used in farms and various industries to shop large amounts of water and avoid problems such as rust, fire or melting of water tanks. They are either delivered ready-made in a factory or built on site where they are to serve their purpose.
