Water and Wastewater usage (EIR2503)

We received your request on 1 December 2025.

We have handled your request under the Environmental Information Regulations 2004.

Your request is set out below:

We formally request under the EIR 2004 regulations Act data you hold, relating to the water and wastewater usage and costs within your controlled portfolio / expenditure.

Given the Governments focus on water control, reduction and competition, there is a valid public interest in local taxpayers knowing what the UK’s public sector across both local and central Government comprises.

For the most recent yearly data to hand: -

1. 1. Your total billed water/sewerage usage?
   2. Your total billed water/sewerage cost?
   3. Name of your water provider?
   4. Are you on a standard water tariff or negotiated/contracted rate i.e. via a framework/direct?
   5. Have you switched water supplier?
   6. Have you ever commissioned or undertaken a water and wastewater audit, with a review to reducing your water and wastewater costs?
   7. Is funding prohibiting you from implementing a water and wastewater cost reduction project?
   8. Have you ever carried out a water consumption benchmark exercise to all of your buildings? If so what is the water consumption per person per year?

Do you have a future water strategy, if so, please supply details.
