Client: The Moray Council
Value: £9.5 million
Location: Forres
The second scheme to be delivered as part of the Moray Flood Alleviation contract, the purpose of which was to attenuate flood waters of the Burn of Mosset upstream of Forres, and providing sufficient storage capacity for a 1 in 100 year event plus an allowance for climate change.
The works comprised the construction of an earthworks dam with sheet piled cut-off to create the required storage capacity; a piled reinforced concrete control structure (baffle crump weir) through the dam, limiting the downstream flow to the capacity of the existing channel through Forres; and a number of secondary embankments to contain floodwaters around the perimeter of the flood storage area; channel improvements remote from the main site at Rafford Burn and within Forres.
The site had badger, otter and salmon activity and licenses were required, and seasonal constraints had to be taken into account in programming the works. A temporary diversion of the watercourse, to allow construction of the control structure, was designed to dissuade spawning fish in this area.
The water supply to Benromach Distillery has its source within the site and crosses beneath the dam, which required great care in constructing a permanent diversion. This project received a Project and an Environmental Commendation from the Saltire Society.
