Middlesex Filter Beds 


Middlesex Filter Beds is a ten acre haven for wildlife and a short walk from the WaterWorks nature reserve. Just off the Lea Bridge Road it as suffered from drying out and a new project seeks to restore the wetland site to a biodiversity hot spot once again. 


History of the site 

Middlesex Filter Beds were built by the East London Water Works Company in the mid 1800’s they demonstrate how previously industrial areas can become valuable habitats for wildlife. 


The filter beds also boast Paula Haughney’s monumental Nature’s Throne, made from huge granite blocks salvaged from an old engine house. 


With a variety of habitats the filter beds provide interesting wildlife throughout the year. The brickwork of the old bed walls provides shelter for a range of wildlife. There are good bird populations and more than 200 plant species have been recorded. 


The site has suffered from vandalism and theft including the generators which kept water in the beds to create the wetland habitat. This has been detrimental to the habitat which has dried out over the last ten years. 


A project is in the final stages of investigation to provide a solution to get water into the filter beds.


The project will undertake the following: 

  • Reinstate the water supply to the filter beds

  • Some extra tree planting around the edge of the site to protect the restored filter beds. 


Funding for this project will come from Capital Reserves of the Authority and should be delivered over the winter or 2022/23. 


Head of Projects and Funding Delivery Lee Valley Regional Park Authority said: 

“We are delighted that we are now very near to a solution to bring water back onto the filter beds which will bring the site back to its full biodiversity potential.”

Update March 2024

We have now gone out to tender for companies to complete the works on this project. The habitat works will be completed by the end of March. We hope that once we have a competitive quote in to fit a new generator and pumps, the water supply can be returned to the filter beds. There is still the option of a permanent electric feed from a nearby sub meter which we are also progressing. We still aim to deliver the interim solution for this project over the winter. The permanent electric feed will be progressed and further developments will be advised on this page.
