What water conservation measures it has (a) introduced in the last five years or (b) plans to introduce.

The Scottish Government is working with key business sectors, Scottish Water, the Scottish Environment Protection Agency (SEPA), and other stakeholders to make sure water is used efficiently through conservation measures.
We continue to invest in the public network, reducing leakage and increasing water efficiency which helps conserve water in the environment, and we are working to develop technologies and other approaches to enhance resilience. Scottish Water encourages its customers to use water efficiently. In the last year alone, Scottish Water Business Stream has helped its business customers save over £14 million through water efficiency savings, and since 2008 it has saved £213 million and conserved more than 38 billion litres of water.
