Water Tank Cleaning and System Chlorination
Water tank cleaning is an essential practice for the prevention of Legionella. Water testing and chlorination should be carried out regularly as a part of your good water hygiene program. Our experts have a wealth of experience and knowledge use a number of different water system and tank chlorination methods, including gravity feed and direct injection.
The Water Tank Chlorination Process
The standard method for water tank chlorination is to dose the header tank with sodium hypochlorite, to a chlorine level of 50ppm. This solution is then run through each system by opening the relevant taps and valves. The water system chlorination is complete after leaving the solution in the system for one hour. A water system sample is taken to check there is no dramatic drop in chlorine levels, if so the process is repeated. The water tank is then drained and filled with fresh water, this water is then used to flush through the system and remove the chlorine.
For closed systems such as mains feed, the water system chlorination is carried out using a drum and mobile dosing pump. The procedure used is the same as the gravity feed, only the drum is dosed instead and the pumps are used instead of gravity.
Water system and water tank cleaning can be carried out with other chemicals, such as chlorine dioxide, which is more effective against Legionella and bio-films. Water chlorination chemicals can also be neutralised, saving large amounts of water and in turn cost.

Our Chlorination Process In Practice
On a recent job carried out at Lower Culham Farm. Our engineers carried out the water tank cleaning and system chlorination on two cottages and a bore hole which fed them. The bore hole had been contaminated with a high level of e-coli. A full clean of the bore hole was undertaken and a chlorination of the pump sets, pipework and water systems was carried out. As a result Water Tanks and Services was awarded the contract for all Lower Culham Farm’s water hygiene services.
