Quality of Public Water Supplies

Scottish Water carried out at total of 23,528 tests on tap samples taken in the water supply zones within North Lanarkshire. The table below provides details of the main parameters tested and totals for the other parameters.

Aluminium and manganese compliance has deteriorated slightly, although iron has improved. All the aluminium failures were in zones supplied by Carron Valley WTW.

Details of Selected Water Quality Incidents

De-pressurisation of a water main following a burst main caused an unknown hydrocarbon to be back-siphoned into the distribution system near Motherwell. This caused numerous taste and odour complaints, although public health was not considered to be at risk. Byelaw inspections of a number of industrial premises revealed several non-compliances, although the exact source of the contamination was not conclusively identified.

Details of Selected Water Quality Incidents

Loss of treatment process control resulted in high aluminium concentrations in distribution and resulting exceedences of the regulatory standard. The incorrect setting of a telemetry alarm resulted in a delay in operational response to this treatment failure and in his assessment of the incident, the DWQR requested that Scottish Water ensure measures are in place to make certain that all alarms are correctly passed on and acted upon.
