What is a rainwater tank used for?

A rainwater tank (sometimes called a rain barrel in North America in reference to smaller tanks, or a water butt in the UK) is a water tank used to collect and store rain water runoff, typically from rooftops via pipes.

Beside this, what are the benefits of rainwater tanks?

Advantages of rainwater tanks are that they:

  • minimise water usage when used in the toilet, laundry or garden.
  • reduce strain on the stormwater drainage system.
  • retain water close to source.
  • reduce site run-off and flood peaks.

Beside above, is a rainwater tank worth it? Rainwater tanks are a great alternative to soakwells when it comes to managing stormwater, particularly if you have a space that doesn't impact your usable yard. The water can be used outdoors, but can also be plumbed to parts of the home to complement standard water supply.

In this regard, how does a rainwater tank work?

When it rains the roof of the house becomes the water catchment area. The gutters on the roof funnel rainwater into the pipes, which connect the gutters to the water tanks. The water is then transported via pipes to the water tanks installed above or below the ground.

Where can rainwater be used?

Simply placing a tap on a rainwater tank can supply rainwater for outdoor uses such as garden watering, car washing, or topping-up your swimming pool or spa. Using water indoors for toilet flushing, clothes washing, bathing, showering, and in your hot water service will require additional plumbing and a pump.

Is rainwater safe to drink?

It is possible, therefore, for us to drink untreated rainwater. This is because rainwater is pure, distilled water evaporated from the sun - nothing else. This water (groundwater) is relatively safe for drinking. However, rainwater that falls to the ground does not just get absorbed into the soil - it goes everywhere.

Can you drink rain water from a tank?

Generally yes. A properly maintained rainwater tank can provide good quality drinking water. Providing the rainwater is clear, has little taste or smell and is from a well maintained water catchment system it is probably safe and unlikely to cause any illness for most users.

Why is rainwater better for plants?

Besides being natural, rainwater is usually soft, which makes it a good option for watering your flowers and plants. Actually, the absence of those very chemicals that make tap water safe for drinking makes rainwater a better choice for your outdoor watering needs.

What happens when water tank is full?

An empty tank will close the downstream pipe, since it cannot drain any more and a full tank will close the upstream pipe, since it can't fill any more. Once the opposite conditions occur in the system, the pipe(s) will automatically open back up.

Can you shower in rainwater?

Most people are comfortable with washing clothes or flushing toilets using rainwater. But experts say that rainwater is completely safe for bathing and showering. Also, bathing in rainwater has some great health advantages. Rainwater is soft by nature, this means there are less minerals dissolved in it than hard water.

How much rainwater do I need?

A general “rule of thumb” is to assume it rains every two weeks. So take your maximum potential annual rainwater collection and divide it by 26 (the number of fortnights in a year). Assuming 240,000 litres of potential rainwater collection divided by 26 fortnights then a tank of around 9,000 litres would be required.

How long can rainwater be stored in tanks?

Rainwater can be stored from anywhere between one week and indefinitely. The more consideration you put into your storage system – using the right materials, preventing algae and mosquitos – the longer your rainwater's shelf-life.

Do plants prefer rainwater?

As long as you live in an area that isn't subject to extremely acidic rain, rainwater is preferable because it's missing things like excessive minerals or disinfectant chemicals. If your plant is not special plant such as carnivorous plant, any water from the tap is okay.

Do rainwater tanks need a pump?

This all means you will need to connect and pump your precious rainwater from your tank into your house. Your water tank pressure pump will obviously need power to pump the water to where it is needed. For domestic purposes, you will want a flow rate of 20L per minute (which is equivalent to your mains water supply).

Do you need to filter rainwater?

Water filters should not be necessary to maintain microbial, chemical or physical quality of rainwater if catchments and tanks are well maintained. Some filter systems will require a power supply. Rainwater supplies may need to be filtered to ensure effective UV treatment.

What happens when rainwater tank is empty?

When the tank is empty, it automatically allows mains water to flow directly into the home. It also ensures that the pump does not turn on when the tank is empty. That means your pump is protected from running dry (i.e. being damaged because it is running without any water in it).

How do you empty a rainwater tank?

The cleaning process normally requires vacuuming the dirty water out of your rainwater tank through a hose and pump. Alternatively, if your tank is big enough to enter, then you can drain the rainwater from your tank and hose and sweep it out.

Do rainwater tanks save money?

Large rainwater tanks may seem expensive to install, but they last a long time. All the water you collect once installed is also free to use – so you can save money in the long term. Every time the price of your mains water supply up, you will save even more with a rainwater system.
