Enabled by funding from the Glasgow City Region City Deal through the Metropolitan Glasgow Strategic Drainage Partnership (MGSDP), the Drumchapel Surface Water Management Plan has seen the creation of a series of embankments and storage areas along the line of Garscadden Burn in the vicinity of Southdeen Avenue and Kinfauns Drive. The storage areas manage high flows during storm events, using the natural valley area as temporary floodplain storage to hold back water and reduce flood risk both upstream and downstream. By reducing pressure on the combined sewer network, infrastructure resilience is increased which serves to lessen the risks and impacts of flooding on homes and businesses whilst allowing greater scope for future development.
As well as improving the amenity of the area by providing habitats for biodiversity, connectivity has also been improved with the installation of new paths and a pedestrian footbridge over the over the burn.
In parallel, Scottish Water completed the construction phase of its £4.8 million sewer flooding alleviation project on Conon Avenue, Bearsden in October last year. This major upgrade to the waste water network will address internal and external flooding in the Bearsden and Drumchapel areas. This project is now in the reinstatement phase, which has been planned in conjunction with local residents and work will begin shortly.
All of these projects are being delivered as part of a phased, collaborative approach between the council, Scottish Water, and East Dunbartonshire Council, linking with the Colquhoun Park Flood Alleviation Scheme that was completed in 2014, and Scottish Water investment at Summerhill Road in 2016. Consideration of further interventions in the Drumchapel area is ongoing as identified in the recently published Clyde and Loch Lomond Flood Risk Management Plan.
