Merton Council’s highways team is continuing to work around the clock to keep the gullies clear of debris as sewers have become overwhelmed with unusually heavy rainfall.
In a night where some areas of Merton experienced up to 50 mm of rain in an hour, the sewers are struggling to cope with the sheer volume of water. In normal circumstances, 10-15mm in an hour would be regarded as heavy.
Council teams are working their way around the borough focusing on the hardest hit areas first.
More heavy rain is forecast today so it is advisable to only make necessary journeys and to leave more time for journeys home from work, as roads and transport services have been affected.
The Met Office has issued an amber rain warning and the Environment Agency has issued a flood alert for the Wandle and Beverley Brook. Where river levels are high, this may affect drainage in localised areas. Major areas to avoid are, Raynes Park under the railway bridge, Bushy Road, Colliers Wood High Street and Baltic Close, Morden Road and Merantun Way in South Wimbledon.
All polling stations are open. There is a large amount of surface water at Sacred Heart, Burlington Road, but it is open and wellies are advised.
Leader of Merton Council, Councillor Stephen Alambritis said: “We are doing what we can in these difficult weather conditions, working around the clock to clear the drains and keep Merton moving. The huge volume of rain has resulted in a lot of surface water and we would advise people to avoid walking through floodwater as you can’t see where you’re walking and drain covers may have come dislodged because of the water pressure. Where we’ve been informed about drain covers and other issues on our roads, we have made the roads safe and have informed Thames Water.”
