UAL's water consumption is at a less advanced stage of monitoring than energy. Due to the way we are billed the most recent data may not be entirely complete.
You can help bring down consumption by reporting leaking taps (you can do this through the carbon dashboard home page), and minimising your use for washing hands and dishes, especially cups.
The information here shows consumption against the previous year for comparison. However this may be subject to significant fluctuations due to reading/billing cycles and not accurately reflect water usage. We're working on improving it.
