Dreaming of vast bodies of water nestled amidst urban landscapes? Welcome to the High Maynard Reservoir, a vital part of London’s water supply system. This reservoir in Walthamstow serves a crucial purpose. It is part of the Lee Valley Reservoir Chain, ensuring Londoners have access to clean drinking water.
The High Maynard Reservoir’s story began in the mid-19th century. The East London Waterworks Company saw the potential of the marshland here. In 1852, they secured permission to develop the land for reservoirs. By 1870, the High Maynard Reservoir was completed adding to the growing network.
The East London Waterworks Company constructed the High Maynard Reservoir. They transformed former marshland into a vital water storage facility. Today, Thames Water owns and manages this important reservoir.
But the High Maynard Reservoir is not just about storing water. It is a haven for wildlife. It has been designated a Site of Special Scientific Interest due to its ecological importance. During the winter months, cormorants gather here in nationally significant numbers. These birds find a safe roost on the reservoir’s island. The reservoir’s fringes also boast a variety of uncommon plant species, making it an important habitat within Greater London.
Beyond its ecological value, the High Maynard Reservoir offers recreational opportunities. The water is open to the public. Birdwatchers flock here hoping to catch a glimpse of the diverse avian life. Walkers enjoy the paths around the reservoir. Anglers cast their lines seeking a peaceful day by the water.
The creation of the High Maynard Reservoir was part of a larger effort to provide London with a reliable water supply. Between 1863 and 1904, ten reservoirs were built in the Walthamstow area. Each new reservoir showcased Victorian and Edwardian engineering prowess. These reservoirs have continuously supplied drinking water to millions of Londoners.
The reservoirs faced challenges during World War II. Walthamstow was bombed, and several reservoirs sustained damage. The water level in Lockwood Reservoir was lowered to mitigate potential flooding. Despite these challenges, the reservoirs continued to serve their vital function.
Over the years, ownership and management of the reservoirs have changed. The Metropolitan Water Board took over in 1904. The Thames Water Authority became the site manager in 1973. Today, Thames Water continues to oversee the operation of the High Maynard Reservoir. The High Maynard Reservoir stands as a testament to the ingenuity of Victorian engineers and the enduring importance of water management.
