Water
Water is a precious resource and we must ensure that we use it wisely. The average person in the UK uses 150 litres of water a day but this is not sustainable in the long-term. Businesses can reduce their water consumption by undertaking simple steps and can save money at the same time. Read more about how you can reduce your water usage.
Saving Water in Business and Industry
Being waterwise is good for your business. All commercial organisations use water, but how many know exactly how much of this precious resource they are using? Predictions are that in Suffolk the summers will be getting hotter and dryer. The East of England is the driest part of the country and water is a valuable resource.
Costs
If you are a manufacturing industry then water bills could be costing your company over 1% of business turnover.
If you are in the retail, hospitality or service sector you could save up to 50% of your water bill. Even if your water use is only for the offices you occupy, there are ways to save water with pay back periods measured in months!
Carbon Footprint
We estimate that currently the delivery of water to consumers produced 344 grams of CO2 per million litres. Treating wastewater is 745 grams per million litres. This is not an exact science and these figures are subject to review.
So what can you do as a business?
The first thing you need to do if you want to save water is to work out how much you use. Conduct a water audit and produce a water management plan that will deliver savings and help the environment. CRed Suffolk's free Environmental Business Adviser can help you address the issue of water conservation.
