just put down a shallow well to water your garden.
theres probably water only a few feet below you.
you say I guess that the thames water company is your supplier so
does that hint that your water comes from the thames?
if so then if your property is less than 29 ft higher in elevation than the thames you could easily get the water from the water table.
unless the uk gov has made natural water usage illegal.
which is what is happening all over the us also.
sad , but there are ways around it.
when they ( the gov ) steps in and causes the the water in the water table to stagnate by refusing to allow people in cities
to use the water that is just a few feet below their property they are causing the water in the water table to retain the toxins that would naturally be cleansed by garden watering.
P.S.
you can put down a shallow well using a 1/2 inch - 3/4 inch pvc pipe !!!
just hook up a 20 ft pvc pipe to your water hose , point the open end downwards and the water coming out of the pipe will drill the well for you.
unless you hit a rock , that is.
