operational updates

Walthamstow Wetlands is a Thames Water operational site which serves 3.5 million people with drinking water. To ensure clean and safe drinking water, there will be times when maintenance works will need to be carried out onsite. To keep visitors safe, these works will occasionally affect the access to Walthamstow Wetlands and the various activities allowed onsite and there will be occasions when areas of the site will need to be closed. Whilst operational work is taking place onsite, we kindly ask visitors to take care and avoid entering the affected area.

Below you will find details on upcoming operational works that will be taking place at Walthamstow Wetlands. Please note, these dates are subject to change and we would ask all visitors to check back to this page for the most up to date information.


As part of ongoing site maintenance works, the height of the Coppermill Gate Entrance is being raised for security purposes. As part of these works, there will be no access to the site through the Coppermill Gate Entrance on Thursday 11 April and Friday 12th April.


As part of ongoing site maintenance, there will be works taking place on the gates and fencing at Walthamstow Wetlands over the months of March and April. As part of these works, the height of all the entrance gates will be raised for site security purposes. For more information, please ask at the front desk at the Engine House.  


As a nature reserve, we have to occasionally limit access to certain areas to protect nesting birds or special wildlife habitats. Please stay on the marked paths and trails and look out for signs - they are there to protect both you and the wildlife.

Currently the path running along Reservoir 1, 2 & 3 is closed due to the area being used as a nesting and breeding site for many birds.
