<strong>2011</strong> ANNUAL REPORT<br />

2A. Percentage of wastewater discharged compliant with consent conditions.<br />

<strong>2011</strong><br />
97% 7/10<br />
New Performance Measure<br />
Target 100% by 2020<br />
Compliance with consents at the major urban wastewater treatment plants remained high throughout the year, although overall compliance levels were<br />
influenced by the poor quality of many of the 17 rural wastewater treatment plants transferred to <strong>Watercare</strong> upon integration. More than half these plants had<br />
a history of non-compliance with consent conditions because of process issues, many of which are difficult and costly to resolve. <strong>Watercare</strong> has developed both<br />
a longer-term strategy and more immediate measures, forecast to cost $50 million, to reduce the impacts of these plants on the environment. On a volume basis<br />
and excluding minor and technical breaches, <strong>Watercare</strong> achieved a 97% level of compliance with consent requirements at its wastewater treatment plants.<br />

New Performance Measure<br />
Target ≤15 per 100km of pipe length<br />
Under the SCI, <strong>Watercare</strong> reports on the number of wastewater overflows from its network during dry weather as a measure of the ability of the network<br />
to manage current demand. For the 2010/11 year, <strong>Watercare</strong> achieved a result of 1.9 overflows per 100km of wastewater pipe, well within the SCI target of 15.<br />
