Question to the Department for Environment, Food and Rural Affairs:
To ask the Secretary of State for Environment, Food and Rural Affairs, what (a) estimate of the number and (b) assessment of the composition of discharges into (i) Liggard Brook and (ii) Main Drain by United Utilities has been made by the Environment Agency in each of the last five years.
There are three United Utilities discharges into Liggard Brook and Main Drain (Ballam Road Pumping Station and Warton Pumping Station respectively) and Lytham Pumping Station at the confluence of the two.
The table below summarises (a) the number of spills from these locations. The figures during 2015 are high due to Storm Desmond. We do not currently hold data from 2016 which is held by United Utilities.
Discharge | FY 2013-14 | FY 2014-15 | FY 2015-16 | 1 Apr 2017 to 30 Sep 2017 | Calendar year 2018 |
Ballam Road PS | 0 | 1 | 51 | 1 | 11 |
Warton PS | 16 | 14 | 0 | 46 | 33 |
Lytham PS | 5 | 3 | 50 | 3 | 26 |
(b) Discharges are from the combined sewer system before it has been treated, so they are made up of sewage diluted by rainfall runoff from roads and roofs.
