How Do Rainwater Tanks Work?
How Do Rainwater Tanks Work? They work by storing rain when it falls. This is know as Rainwater Harvesting. The roof of a house is the most common catchment area. The gutters funnel the rainwater directly into the tank.
After you have decided what shape tank you need (round or slimline) and what size tank you want, you will need to decide where to locate it (them) and prepare the site.
What Fittings and Accessories Do You Need?
Rain can be harvested from your roof, instead of flowing away from your property. It can be collected in the gutters and then sent via a pipe from a point in the gutter to the top of the tank. Of course, you can have more than one tank and/or more than one pipe coming from different places in the gutters.
Select water tanks come supplied with a special inlet filter on the top of the tank. They contain two parts: The first part consists of a fine mesh to act as a filter to keep debris and insects from entering the tank while still allowing the water to enter.
The second part consists of a black plastic tray designed to keep any light from reaching the water stored in the tank to minimise the growth of algae. This tray has slots around its edge to allow the water to flow through into the tank. You can tell us where on the top of the tank you would like the inlet filter to be located so it will be most convenient for the pipe coming from the gutter. A cover for these inlet filters can be purchased.
Select water tanks also come fitted with an overflow fitting which is normally placed as high up the tank as possible. This consists of a small pipe fitting to allow any excess water to flow from the tank. It contains a fine mesh to prevent insects from entering the tank. Again, you can tell us where on the tank you want this fitting to be located so that it is in a convenient location to suit your tank and site. They can be either 90mms or 100mms in diameter.
Select water tanks also come with a standard water outlet fitting unless you specify something different. This consist of a ball valve and a tap which come in two different sizes. You can also order outlet fittings that are fire-fighting compliant. You can tell us where on the tank you want it located. Some people also order an additional ‘bucket tap’ which is located high enough up the tank so a bucket can be placed underneath it for ease of filling it with water.
If you need to capture and store a large volume of water you may wish to order multiple tanks. For example, you may wish to order three round tanks and have them linked up so that they work together to deliver the volume of water you need.
Select does not automatically provide pumps or filtration systems. We can provide them for an additional cost or you can provide them yourself. We do however, make a special product called the Puretec Hybrid Plus Filtration System. The Hybrid Plus Series is a range of “All in One filtration system” within a weather cabinet. The lockable cabinet has gull-wing style access doors for ease of access for maintenance and incorporates adjustable feet to ensure a neat and tidy finished installation.
Select will deliver the tank(s) to your property and place it/them on the site (pad, slab, stand) you will have prepared. There is a delivery cost. We can coordinate with a crane service to lift it/them into place if that is necessary.
Select will not hook up the tanks to your local water supply. We recommend that you use a local plumber so that any connections meet local requirements and you will then have access to a local expert if needed in the future.
