We have constructed two shaft structures at our Heathwall Pumping Station site. The smaller shaft is located within our cofferdam, a dry working area built into the river. This shaft will transport intercepted sewage from the Heathwall Pumping Station to a depth of 28m below ground. Our second, larger shaft is approximately 47m deep. As well as receiving sewage from the Pumping Station via our smaller shaft, this structure will drop intercepted sewage from the existing sewer at this location.
At Heathwall, we are currently removing the roof from the South West Storm Relief chamber. The works are scheduled to begin on Wednesday, 2 November. Due to the nature and location of the works we will be required to work during the low tide working windows (which are approximately eight hours in duration). The works will take around eight weeks to complete.
While the majority of the works that include breaking and cutting will be carried out during core hours (8am to 6pm Monday to Friday and 8am to 1pm on Saturdays), there is the possibility that we will be required to do some noisy cutting and coring outside these hours, due to the early or late tides. These may include early mornings from 5am and later evenings up to 9pm on Monday to Friday and between 1pm and 6pm on Saturdays.
We have constructed extensions walls around the chamber and this will assist in providing extra acoustic barriers against any noise.
