Drinking Water Quality

Tardis H2O on site are well practised in ensuring your drinking water supply is fit for purpose.


Certain tests are carried out by UKAS approved laboratories giving detailed and in-depth reporting on bacteria levels.

We take the samples and working to DWI (Drinking Water Inspectorate) and H&S guidelines, the samples are stored in controlled conditions before being passed to the labs.

Common tests include testing for the presence of E. coli, coliforms and Legionella.


UKAS accredits laboratories to provide traceable calibrations and measurements. UKAS is recognised by the UK government as the national accreditation body.


Tardis H2O on site follows strict guidelines set out in ACOP L8 (2013) Legionnaire’s Disease, the control of Legionella bacteria in water systems. Also the DWI (Drinking Water Inspectorate guidance document on the implementation of the water supply (Water Quality Regulations 2000 as amended in England 2012)
