Information Commissioner's Office

Southern Water

13 February 2017, Private companies

The complainant has requested the location of all wastewater treatment works (WTW’s) in Southern Water’s area, including addresses and grid references. Southern Water provided a list of names of WTW’s and their postal towns but withheld the more specific location information on the basis of regulation 12(5)(a). Later in the investigation, Southern Water also sought to apply regulation 12(4)(b). The Commissioner’s decision is that the regulation 12(5)(a) is engaged and the public interest favours maintaining the exception. No steps are required of Southern Water.

EIR 12(5)(a): Not upheld
