maintenance records, property files, PIMS/LIMS. These sources of information are rarely consistent and considerable effort is required to determine the accurate and reliable data. An exercise has been undertaken with technical administrative staff preparing LIMs/PIMs reports to determine the quality of information needed for their purpose. A protocol was established to record the degree of accuracy; the source of information transcribed into the AMIS/GIS system and to confidence grade the source. Underground services that can be recorded to within 300 mm, with a high degree of certainty are given a confidence grade of 1. Confidence grade 2 is within one metre accuracy and confidence grade 3 is less certain. Similar grades are given to the material type and age of an asset. Two temporary contract employees were given permanent contracts in 2011. They have been systematically transferring data from the various hard copy sources to the electronic information systems. The systematic ‘sweeping’ of areas has been mapped to record and communicate progress to other staff. There is a margin of variance between the different networks but around 65% and 75% have been ‘swept’ to a consistent and high standard. There are instances within the asset register of data that has been estimated or taken from less accurate sources. For example the installation date of some pipes in Picton was recorded as the date the record drawing was created and not the correct installation date. Some errors and estimates have been tolerated as adequate in the circumstances but need to be corrected through further research.

Unaccounted for Water A number of technical reports on water supply have included a desk-top assessment of leakage and unaccounted for water. The apparent levels of leakage in Picton, Havelock and Renwick are very high. Further investigation and evaluation is required but leakage control strategy should be included in an overall demand management strategy.

Growth pockets have been identified and re-assessed for land suitability following the liquefaction issues experienced in the Canterbury earthquakes. Seven zones to the north and west of Blenheim have been zoned for urban residential development. The Assets and Services Department are preparing more detailed plans for the urban development Page 88
