Welwyn Weir Works

Welwyn Weir WorksAWM were tasked to replace three weirs controlling water levels upstream of a mill on the River Mimram near Welwyn Garden City.

 

These weirs will be modified in due course as part of a project to improve fish passage through the catchment.

Arundel Flood Defences

Arundel Flood DefensesWorks were completed in 5 areas around the historic town of Arundel to repair low spots in the flood embankments protecting the town and surrounding farmland from the tidal River Arun. The works were for the Environment Agency and lasted 8 weeks. In this photo a long reach excavator fitted with a vibrating plate compacts a blend of imported material to ensure a sound free draining repair.

We have just installed this maintenance platform to enable safe weed clearing from a drainage channel for the Environment Agency near Rye in East Sussex.

Oxford River Wall

Oxford River WallDue to it’s age and the burrowing of Signal Crayfish, this 40 metre section of historic wall in central Oxford on the River Cherwell required re-building.

So it has been brought into the 21st century with new crayfish proof footings and a solid concrete wall behind faced with the original stone and incorporating new drainage.

Aquatic planting was included at the toe of the wall and wildflower turf at the top as wildlife mitigation and to improve the aesthetics.

Green Bank Protection

Green Bank protectionThe banks were badly eroded on this stretch of the Alder Brook in Cranleigh, Surrey. AWM installed these soil filled Flex MSE bags for Waverley Borough Council which lock together with spiked plates to make them additionally secure. They will be hydraseeded with a suitable seed mix which will grow through into the soil in the bags to produce a soft green sustainable solution to a common problem.

River Mole Fish Pass

Once commissioned next week it will enable fish and eel passage to the upper reaches of the mole for the first time in several hundred years!
