(2) if he will estimate the (a) increase over the last decade and (b) predicted future increase over the next decade of the number of (i) swimming pools, (ii) jacuzzi and other water spa pools and (iii) decorative domestic water features and ponds; and what assessment he has made of the likely impact of these changes on per capita demand for water.
The Government’s Market Transformation Programme (MTP) allows us to assess the impact of a range of products on water use, including toilets, taps, showers and baths. The MTP is also undertaking a scoping study to determine which other products use significant amounts of water. This will include an assessment of the amount of water consumption associated with swimming pools, hot tubs and spa baths. There is currently no evidence to show that ornamental garden water features involve significant levels of water consumption.
The MTP will shortly be setting out, for public consultation, the Government’s current evidence and analysis on showers. This consultation is part of a wider annual review and policy development process, supporting delivery of the Government’s objectives for energy, water and for sustainable consumption and production.
The paper includes indicative targets and eco-design standards for showers which are sold and used in the UK. The MTP work indicates that if no new policy actions are taken, and current underlying trends continue, water consumption by showers is expected to rise by 48 per cent. by 2020 compared to the 2006 baseline. The policy actions proposed in the document show how this projected increase can be constrained.
