The commissioner was initially reluctant to renew the consent and adjourned the hearing in order to receive further evidence. The bores are used to support the Malthouse Lane supply at times of peak demand and provide irrigation water to nearby vineyards. The bores are not heavily used currently but are regarded as important as demand for industrial process water in the Riverlands Industrial Estate and the Cloudy Bay Business Park is anticipated to grow considerably in the future. The new consent was granted in 2014 but the maximum rate and volume of abstraction was restricted and strict consent conditions were imposed to protect the aquifer from saltwater intrusion. The restrictions also protect the rights of other users and the sustainability of the natural environment in line with the Regional Management Plan. Domestic Demand in Picton - The pattern of water consumption in Picton is similar to Blenheim. There is some evidence of a decline in overall consumption whilst the population has grown. The per capita consumption of water also suggests a small decline in water usage. The average of 800 litres/person/day is higher than Blenheim but may be partially explained by the difference in business usage as the gross figures include industrial and commercial water usage. Business consumption in Picton is around 20% of the total supply based on a sample of four years of meter records. Peak demand days are similar to Blenheim at around 1,400 litres/person/day. This estimate is based on usual resident population and does not account for the influx of summer visitors. It is likely the corrected figure would be below the Blenheim consumption. Analysis of the data has revealed that peak demand days are relatively rare. Over the period between 1998-2011 there were 57 occurrences when consumption was greater than 70% of average (18 days only 2003-11.) The same relationship between consumption and evapo- transpiration exists in Picton as Blenheim, suggesting large volumes of water are used for garden irrigation. Page 40
