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 mms in diameter. In urban and suburban areas where town water is available, it is not recommended to drink rainwater.
In rural areas it may be possible to drink harvested rainwater, but you will need to install a filtration system to do so. Water tanks may also play a role in storing water that is supplied by local authorities. Every home would benefit from having a water tank installed that is large enough to sustain the home for a considerable period of time, even if rain is scarce or the water supply from the local authorities stops.
Depending on the property, a water tank can either be placed on the ground, below or even be elevated above the ground on a stand or platform. Above ground round polyethylene tanks are often the most cost effective option. When choosing the most suitable water tank, it is important that every homeowner takes a few factors into consideration:. These are best installed above the ground.
Benefits of collecting rainwater through tanks Aside from the fact that it is a good alternative to increase water supply especially in the regions North and mid-North Coast, South Coast, Southern Highlands, and other areas in NSW, here are the reasons people should get water tanks: Reduce water bills Protect the remaining natural sources of water Reduce operating costs on infrastructure Lessen the need for new desalination plants or dams How does it work?
This is how water tanks simply work: First, rainwater is collected on a catchment area usually from the roof where it is then funneled to the gutters. Then, it flows water to the pipes and into the tank. Next, a pump pulls water out from the cistern via a small pipe. Then, the water passes through a filter. Afterward, it enters into the pressure tank, which gives sufficient water pressure to the fixtures inside the house.
Conclusion: The NSW Health supports the utilization of water tanks NSW such as concrete rainwater tanks in collecting rainwater for non-drinking purposes. There is usually no problem with installing smaller tanks for just garden watering. You are also required by law to ensure that the mains water is isolated from the rainwater system. This is achieved by using a backflow prevention device.
A qualified plumber must install this and you may be required to have annual checks on this device. Most councils will require you to connect to the mains water if there is a connection available, even if you will only use it as a backup. Check the rules with your local council. Some councils sell these, so check with yours. In areas such as Auckland, with year-round rainfall, a smaller tank might be enough for the garden. If you live in an area with dry summers, or you water your garden a lot, you will need a larger tank.
If you are planning to use rainwater for indoor supply, you will need a larger tank. In areas with year round rain, a litre tank will provide a good proportion of your water use.
If rainwater is your sole source of water, you will need at least a 30,litre rainwater tank. Talk to your local suppliers to find out the size that would best suite your climate and household. If you live in the city and are short of space, you could install a slim-line tank that fits alongside and attaches to a wall on the side of your house.
Water is heavy, so even slim-line tanks need to be well supported. Contact your local rainwater tank supplier you could search for 'water storage' and 'tank manufacturers' using an online search tool or ask your local council for advice on the capacity of your rainwater tank. The most common tank materials are plastic polyethylene , concrete, and coated steel.
The type of material you select depends on your budget, the size of tank, water use and whether the tank will be sited above or below ground. Modern steel tanks have a long life polymer coating on the inside and a wide range of shapes and sizes are available. There are a range of slim-line designs suitable for urban sections available.
Concrete tanks are strong and can be sited below the ground. Plastic is tough, durable and relatively lightweight, and — like steel — there are a wide range of sizes and shapes suitable for urban environments. Other types of tanks include fibreglass and timber. Timber tanks have a plastic bladder liner, and generally come in larger sizes.
