The ADOC Boards maintain 85 miles of watercourses………….

…………….12 pumping stations and numerous structures, including  tidal outfall structures.

We aim to carry out some form of maintenance on all of our drainage assets at least once a year unless a watercourse is culverted (piped) or we cannot get access due to inappropriate development of unlawful activities.

Watercourse Maintenance

Watercourse Maintenance activities include:

– Tractor Flail Mowing (grass cutting the banks)

– Weed Control (moving weed from the channel of the watercourse)

– Silt Removal (i.e. sludging – Removing excess silt from the channel of the watercourse)

– Regrading (pulling back slipped banks to their design profile)

– Stabilsation Works (piling or other structural works)

Pumping Station Maintenance

Pumping Station Maintenance activities include:

– Regular servicing

– Screen clearance

– Repair and replacement of moving parts

– Security of buildings
