Outfall Safari along the River Ravensbourne - looking for volunteers
It is five years since we ran our first Outfall Safari along the Ravensbourne river catchment and it’s time to run another health check on our rivers. A stretch of the River Ravensbourne flows through the eastern side of Beckenham Place Park.
This is an opportunity for volunteers from Keston to Deptford, from Eltham to Sydenham, to join us and help identify pollution hotspots and raise public awareness around drainage misconnections that can harm our rivers.
The waterways of the Ravensbourne, Quaggy and Pool join the Thames at Deptford and, like all London’s rivers, they can be polluted by chemicals found in detergents, building material, paint etc and by sewage due to misconnected plumbing. Pipes that lead into surface water drains, rather than into sewers, bring these pollutants into our rivers and impact the species that live in them.
While Thames Water and the Environment Agency monitor the river catchment and respond to pollution incidents, it is very hard to create a detailed map of all the troublesome outfalls that have, so far, remained under the radar. An Outfall Safari is the answer.
Designed to be undertaken by local volunteers, an Outfall Safari requires no expertise beyond simple data collection, which is covered by bespoke training in March, and keenness to take walks alongside our rivers.
This is a short-term commitment: it will be run over a period of around one month (April 2022) and relies on lots of small teams of volunteers each doing as much or as little as they want. One team member will record the observations of the group using a simple mobile App, and the uploaded data collected by all the teams will create a detailed picture of the current state of the catchment.
Outfall Safari training will be on Wednesday, March 30th from 10.30am to 12.30pm at the Athletics Hub meeting room in Sutcliffe Park Sports Centre, London SE7 5LW. The trainer is Phoebe Shaw Stewart of the Zoological Society of London. The training is of course free.
An Outfall Safari gathers valuable information. Data from the App is mapped and passed on the Environment Agency and Thames Water. And any severe pollution revealed can be investigated immediately by these agencies. It is a proven method of checking on London’s rivers, already tested on the rivers Crane, Wandle, Hogsmill, Dollis Brook and many more. It relies fully on Citizen Scientists! Which could be you.
