A UK Water Company has expressed its intention to apply best practice and demonstrate increased due diligence to the regulator and their customers. As a result WRc were approached to apply this concept as the basis for establishing an effective disinfection policy.
The project will deliver a:-
-
Disinfection Policy: based on consistent good practice drawn from guidance available from WHO, EU and implemented in member states (most notably Netherlands & Sweden), Australia, United States of America and Canada with consideration given to making the output consistent with DWI’s Regulation 26 requirements;
-
Compliance Assessment Tool: an MS Excel based tool to assess the adequacy of a range of treatment methods applied to water sources to eliminate pathogens for:
-
Groundwater not known to be under the influence of surface water with minimal treatment,
-
Groundwater impacted with surface water with marginal chlorination,
-
Groundwater impacted with surface water with full chlorination,
-
Surface water with conventional physical treatment (clarification and rapid gravity filtration) and full chlorination, and
-
Surface water with slow sand filtration and full chlorination.
The project will enable:
-
Alignment of the disinfection policy with international best practice and improved reputational standing;
-
Improved understanding of necessary disinfection protocols and disinfection activities made; accessible to managers and operators of a range of different water sources and treatment processes;
-
Reduction in customer and corporate risk;
-
Demonstrating due diligence to the water quality regulator with an evidenced supported approach to ensuring the microbiological safety of drinking water.
