With water levels just 45.6m below ground level and rising at the rate of 3 metres per year, London’s water table poses a serious long term threat to the capital.
How do I find out my water table level UK?
The water table can be viewed directly by drilling an observation well into the groundwater body and waiting for the water level to stabilise. Repeated measurement of the water level in this well over a year will reveal that the water level fluctuates, perhaps by a metre or more.
Is there an aquifer under London?
There are three principle aquifers within the Thames Basin: the Chalk, the Oolitic limestones of the Jurassic and the Lower Greensand. These aquifers provide about 40 per cent of the region’s water supply and support significant river flow and wetland habitats.
How deep is the water table usually?
50 to 300 feet
Although the water table varies throughout the Oglalla Aquifer, it is generally 15 to 90 meters (50 to 300 feet) below the land surface. Industrial agriculture and development in the 1940s and 1950s contributed to lowering the water table by more than a meter (3.5 feet) year.
Is the water table rising in London?
Current situation

How do I find my ground water table?
The most reliable method of obtaining the depth to the water table at any given time is to measure the water level in a shallow well with a tape. If no wells are available, surface geophysical methods can sometimes be used, depending on surface accessibility for placing electric or acoustic probes.
Can you dig a well anywhere?
You probably can drill your own well on your property. You, of course, would have to contact your local building department to see if there are any regulations that must be followed.
