Water Quality Awareness 101 7 | P a g e 7. SECURITY Site security of all water assets is an important part of protecting drinking water systems from source to customer. Where possible, limit access to catchment areas and control who can enter water treatment facilities, pumping stations, disinfection dosing sites and treated water storage tanks. It is important to have a security record and plan in place and be able to monitor who is accessing drinking water related sites and what activities they are carrying out on site. Having an up to date key register and installing security cameras will allow sites to be monitored accordingly. Regularly check for evidence of unauthorised access (e.g. graffiti, fence damage, tyre tracks etc.) and inform the appropriate persons in your organisation if anything suspicious is noticed. Know who has access to the site and what activities are conducted SECTION 2: SPECIFIC ADVICE This section should be read by personnel involved with specific activities involving contact, or potential contact, with treated drinking water.

If the location of the main repair is within the reticulation system, downstream of the water treatment plant, there will be no way to prevent contaminants reaching
