www.wwtonline.co.uk | JUNE 2018 | 9 Water company GOAL 1: Improve customer experience Customer experience aer PR19 will be measured by the new C-MeX index which is in development and is a succes- sor to the Service Incentive Mechanism (SIM). Water company GOAL 8: Reduce pollution incidents Defined as category 1 – 3 pollu- tion incidents per 10,000km of sewerage network, as reported to the Environment Agency or Natural Resources Wales (sew- erage companies only) Water company GOAL 4: Reduce supply interruptions Supply interruptions greater than three hours are counted, averaged out and then expressed on a per-property basis. Water company GOAL 11: Reduce mains bursts This asset health metric is de- fined as the number of mains repairs needed per 1,000km of water mains per year in a water company's area. Water company GOAL 2: Improve developer experience This is to be measured by a new developer services meas- ure of experience (D-MeX) based on a survey of developer customers. Water company GOAL 9: Build drought resilience This measure is the risk of se- vere restrictions in a drought, defined as the % of the popu- lation that would experience severe supply restrictions in a 1 in 200 year drought. Water company GOAL 5: Reduce leakage Leakage is in megalitres per day and expressed as a three- year average. Ofwat has stated its expectation that water com- panies will achieve an average 15% reduction in leakage over five years. Water company GOAL 12: Reduce unplanned outages This measure of asset health takes account of instances where there is an unplanned, temporary loss of production capacity – such as a treat- ment works having to be taken offline. Water company GOAL 3: Improve drinking water quality Water quality compliance as measured by the Drinking Wa- ter Inspectorate's Compliance Risk Index (CRI). Water company GOAL 10: Protect against floods This new risk-based resilience metric for wastewater meas- ures the risk of sewer flooding in a storm – defined as the percentage of the population at risk of sewer flooding in a 1-in-50 year storm. Water company GOAL 6: Reduce water consumption This is expressed as per capita consumption for a water com- pany's area – i.e., the amount of water used per person per day. Water company GOAL 13: Strengthen sewer resilience The number of sewer collapses per 1,000km of sewer per year (sewerage companies only] Water company GOAL 7: Reduce sewer flooding The number of internal sewer flooding incidents per year (applies to sewerage compa- nies only). Water company GOAL 14: Improve environmental water quality Wastewater treatment works compliance, as measured by the Environmental Perfor- mance Assessment conducted by the Environment Agency.
