To ask the Scottish Government how many (a) combined sewer overflows (CSOs), (b) settled storm sewage overflows (SSSOs) and (c) emergency overflows (EOs) in Glasgow are currently monitored for overflow events, and what percentage this is of the total number.
As published by Scottish Water on its website at https://www.scottishwater.co.uk/Your-Home/Your-Waste-Water/Overflows/Prioritisation-of-Sewer-Overflows-in-Scotland, there are some 4,080 CSOs on its network.
Scottish Water publishes data on all monitored overflows on its website, and recently launched an overflow map at https://www.scottishwater.co.uk/Your-Home/Your-Waste-Water/Overflows/Live-Overflow-Map. The overflow map lists the number of monitored overflows by local authority.
