Blog Post WSW Freshwater Friday Post ‘Save Water Save Wildlife’ by Nathan Richardson

Why is freshwater important?

  • Freshwater is essential for our planet. It is vital for humans & wildlife to survive. Freshwater environments include rivers, lakes, wetlands, streams and underground aquifers – these are all crucial to the water we need and drink.
  • Only about 3% of earth’s water is freshwater, with 1.75–2% frozen in glaciers, ice and snow, 0.7–0.8% as fresh groundwater and soil moisture leaving less than 0.01% of it as surface water in lakes, swamps and rivers.
  • Population growth & climate change is causing a huge impact to freshwater availability and by 2030 nearly half of the world’s population will live in areas of high water stress.
  • The combination of population growth, spiralling increase in water use and pollution have put huge pressure on our rivers and streams. Research shows that a third of the water we take from rivers is wasted.

What can I do?

  • The average roof collects about 85,000 litres of rain in a year. This could fill 450 water butts with free rain water.
  • It’s okay for the lawn to go brown, it helps it to build up resistance and recover immediately after rainfall.
  • Sprinklers can use as much as 1000 litres per hour! This is more than a family of four use in a whole day. If you have to use a sprinkler, try to use it in the early morning/late afternoon when evaporation rates are the lowest.
  • Pressure washers should be used sparingly. Look out for water efficient models that are available.
  • Attaching a trigger nozzle onto your hosepipe will halve the amount of water used and help direct the flow to the root of your plants.
  • Watering cans can significantly reduce the amount of water used whilst getting the desired amount to your plants.
