Rainwater Harvesting Carmarthenshire

Every home owners dream is to reduce outgoing costs and to help contribute to a better environment. Totally Sustainable help homeowners to do just that. we provide support and install rain water harvesting systems to reduce all energy bills whilst making your home or business future proof.

Rain water harvesting systems collect and store rain water which then can be recycled and re used in the future.

Instead of wasting all that rain water that fell over night, why not store it and use it for things such as:

  • Watering the garden
  • Washing cars
  • Jet-washing
  • Topping up swimming pools


The biggest benefit is it saves homeowners money on water bills.

Mains water is a precious resource due to increases in demand as the UK’s population is increasing. There has been a lot of change in rainfall patterns in the UK, which has caused drought and flooding conditions. Rainwater harvesting can provide around 50 per cent of a family’s water needs.

Rainwater harvesting is the collection and storage of rainwater that would normally flow down gutters into the drain. Rainwater is collected from the roof, then re-used within the home and garden. This can provide substantial savings on water bills, as well as making your home more sustainable and efficient.

Rainwater can be used for all outdoor uses: washing cars, watering the garden, cleaning patios, drives and windows, topping up swimming pools, ornamental ponds and hot tubs.  It can also be used inside the house to flush toilets and feed washing machines.  Rainwater use encourages less build-up of calcium deposits in appliances, in comparison to drinking water.  The diversion of rainwater to the storage tank can in many situations attenuate flooding.
The principle uses for rainwater are:

  • Toilets
  • Washing Machines
  • Garden/Outside Use

Studies show that each person in the UK uses in the region of 150 litres of drinking quality water every day.  Around half of this amount need not be drinking water. This means water has gone through an energy and carbon intensive process of filtration, chemical treatment, and pumping from miles away, just to be flushed down a toilet or water the lawn.  Clearly,this is a waste of our resources! By installing a rainwater harvesting system you will do more than help protect the environment and:

  • Reduce water bills by around 50%.
  • Increase chances of your planning gaining permission
  • Provide your garden with water during a hose pipe ban
  • Reduce flood risk
  • Provide your home with soft, lime scale free water for washing machines and toilets; helping to prevent breakdowns and reducing the amount of detergent needed

Completely! Rainwater is better for your garden than mains water because it does not contain the chemicals needed to make mains water drinking quality.

Yes! Typically you will save around 50% on your current metered bill – if you are keen a gardener or have large water requirements, the savings can be even higher!

Yes. Domestic rainwater harvesting systems filter the collected rainwater very heavily and water is stored below ground where it stays at a constant, cool, temperature and away from light – meaning it is practically impossible for any bacterial action to occur. Collected Rainwater stays perfectly clean, clear, and odourless if it is in a properly installed and maintained system.

Water can be boiled and treated with UV filtration to make it drinking quality, yet this is only economically viable where occupants are off grid and have no mains water source. Within a normal system, rainwater is classed as non-potable or non-drinking water by UK water regulations – this means it cannot be used for applications where there is human contact such as drinking, bathing and cooking.

The UK Building Regulations specify rainwater as non-potable water. But if you get the water tested and fit the right equipment you can use your rainwater all over the house even for drinking.

It is vital to get water tested if the users or authorities want to be certain of its quality. There are testing companies all over Britain and one can identify them locally when required. Most council inspectors will want to see test results and a confirmation from a supplier that the equipment will handle whatever might be polluting the water.
