Boxers Lake A Cause For Concern

The aim of the project is to reduce urban pollution such as road run-off in the Salmons Brook by creating sustainable urban drainage systems (SuDS) in 6 locations along the brook and its tributaries, including Boxers Lake on the edge of N21.. Thames 21 tests showed that there are very high levels of phosphate,Phosphate can cause algae and duckweed to grow very vigorously, which can then cover the surface of water, block out sunlight and reduce oxygen for other plants and fish. Sometimes the algae can be dangerous too, in the case of blue green algae, which can be seen in some other lakes in the borough. The water here is also warmer than elsewhere, which suggests that outfflow from misconnected pipes from houses near the lake is causing the problem. Thames 21 Project Manager Aimee Felus, who conducted the tests says that that misconnections, whereby a property is plumbed incorrectly are common,.

 

Thames 21 estimate that around 10% of homes are misconnected and this is a problem along the whole of the course of the River Lea. This means waste water from washing machines, showers or toilets is going down the drainpipe instead of into the sewer pipe. Drainpipes are just meant for rain – many lead to local rivers. With thousands of properties polluting their river it adds up to a heavy burden on the environment. For example a washing machine or dishwasher (dishwasher tablets are high in phosphates) might be connected to the drain meant for rainwater (which goes straight to the local stream) instead of the sewers (which go to the treatment works). A Lonsdale Drive resident has noted that the swans and geese appear to be spending less time in the lake than in the past and have been waddling up the road awy from lake, causing a potnential accident hazard. People can check if their house is misconnected using the checker on the ConnectRight website and Thames 21 will contiue to work with residents, Enfield Council, Thames Waterand

 

The Environment Agency to ensure that there are improvements in water quality. http://www.connectright.org.uk/ As part of the treatment Thames 21 are SuDS, which are 'green sponges', which are being planted and will naturally intercept and remove pollution, provide storage for flooding, and create new areas of wildlife habitat. All the work will be done alongside local people, and sites will only be selected if local people want to have SuDS there. Key to the success of this project is ensuring we collect excellent data to establish current levels of pollution and show the positive effects of SuDS installation, which we are doing in collaboration with University College London. Thames 21 are looking for volunteers to help with its projects. This presentation provides an update of the SuDS project, wih plans for creating new wild spcaes that local residents can use.
