Recent Updates in the Scottish Water Industry: What You Need to Know

In the ever-evolving landscape of the UK business water market, policy changes are continuous. The latest shift in the Scottish Water’s Return to Sewer (RTS) allowances could mean significant savings for businesses, especially Golf Clubs like yours.

What is Return to Sewer (RTS) Allowance?

Return to Sewer (RTS) allowance pertains to the amount of water consumed that is assumed to be returned to the sewerage system. For billing purposes, it is the volume of wastewater you’re charged for as a percentage of water recorded by your meter. By default, this stands at 95% in Scotland. However, based on recent modifications, this might not be the most cost-efficient rate for you.
