Chemical Dosing Security

Galliford Try has provided Scottish Water / Scottish Water Services with end-to-end solutions for security since 2004. We have been involved from the initial Capital Expenditures (CAPEX) build up to the final output claim and acceptance from the Water Industry Commission (WIC) and Drinking Water Quality Regulator (DWQR).

Scottish Water was required to bring all of the secondary chemical dosing sites - sites that are located out with the site boundary of a water treatment works which dose chemicals into the treated water main - into compliance with Government security advice notes. All sites, as a minimum, were to be fitted with monitored dual technology alarm system capable of detecting the opening of the housing containing the chemical dosing equipment and liquid chemicals.
