In preparation for what is forecast to be a very wet winter, the property owner wanted to take advantage of a dry spell, when his water tanks where at a low level to given them a thorough clean.
As the property is not in mains water a clean supply of drinking water is crucial.
The tank had not been cleaned since installation 5 years earlier so the base and interior walls of the tank where coated in slime and algae.
We used a mix of high pressure water and gentle scraping top remove the layer of grime.
