To ask the Minister of State, Department for Transport what estimate he has made of the water consumption on his Department's estate in (a) 2005-06 and (b) 2006-07, (i) in total and (ii) per full-time equivalent member of staff. (280962)

The Department for Transport reports its water consumption figures through the annual Sustainable Development in Government (SDiG) report. The scope for water consumption changed from offices only in 2005-06 to the entire estate in 2006-07. As a result of this change in scope, the Department reset its baseline for water consumption. Therefore the water consumption figures for 2005-06 and 2006-07 are now as follows:

The above figures represent the whole estate. To break these figures down to office and non-office data would incur disproportionate costs.
