Conserving water

Water is a precious commodity; life would not be possible without it.

This page outlines how to conserve water.

Water scarcity and flooding are problems in different kinds of weather.

Cleaning, recycling and redistributing water use electricity and add to our carbon footprint.

Rising populations are also putting strains on our resources. Roughly speaking we each use about 160 litres of water every day per person.

Climate trends

More and more, the climate is running to extremes. Either we have no water, or more than we can cope with. That’s due to climate change.

In spite of the heavy rain of recent times, the water supply in England remains under long-term threat. It may seem hard to believe, but London gets less rain than Rome or Sydney!

Tips to save water

There are simple ways to cut consumption:

  • Do you have a water meter? This helps us stay aware of how much we are using, and rewards us for using less by cutting water bills
  • Check for leaks on pipes and taps. If you do have a water meter, turn off all the taps and the main stop valve, where the water enters the building. Take two readings a couple of minutes apart. If there is any change in the reading you may have a leak
  • Fix leaking taps and make sure they are fully turned off. In a public area, consider a sign to not leave taps running. New taps can be spray types, or have limiters, or a timer to turn off automatically
  • Lag your pipes. This saves on your heating bills, and prevents burst pipes in winter. But don’t insulate a loft floor underneath your water tank – it may freeze
  • Save both water and electricity by only boiling as much water as you need, whilst making sure the electric heating element is fully covered
  • Make sure sinks have plugs and use a bowl to wash up
  • When replacing your washing machine or dishwasher, choose the most efficient type. Run them full but not over-full
  • Collecting rainwater in a water butt, and use it for the garden.

Drainage

Most parts of London have combined drainage of surface water and foul waste. Surface water comes from roof, roads and pavements; foul waste comes from toilets and sinks. They are cleaned together, then returned to the River Thames in East London.

Unfortunately in heavy rain, the sewers overflow, tipping foul waste together with surface water into the River Thames, which kills the fish. This is made worse when we pave over our patios.

In outer areas, and outside London, water and waste are kept separate. Rainwater runs straight into the nearest river. It doesn’t get cleaned, so it’s important not to pour anything harmful into an outside drain.

Our water supply comes from ground water, i.e. from gardens and parks, and from the rivers. The water is subject to rigorous tests so it’s safe to drink.

Concerns have been raised about glyphosate weedkiller getting into our water supply. Thames Water actually prefer glyphosate to other weed killers. They say it degrades quicker before sinking into the ground water aquifer which supplies much of our water. See also Weedkillers.

Benchmarking water use

The Diocese’s Energy-saving Benchmarking scheme now also extends to assessing how efficient your church is in its use of water.
