My Lords, I put my name to Amendment 189 of the noble Baroness, Lady Parminter, on domestic water efficiency. I understand that the Government are committed to water efficiency standards and labelling, as signalled in their recent ministerial Statement on reducing water demand. The Government’s helpful brief on the water issues in the Bill says that they are currently considering the most suitable and effective mechanism for water efficiency labelling. This amendment does the job for them. I hope the Minister accepts it and makes swift progress to tackle the demand side of the supply-demand balance.
For too long, the water products industry has dug in, dragged its heels and resisted labelling. I remember being involved in endless discussions on water efficiency and labelling products 15 years ago. We are drinking in the last-chance saloon—if that is not a pun in the context of water.
As I said earlier on the Bill, our average water consumption has barely changed over the last 15 years. The Government have a target of at least 125 litres and preferably 110 litres per person per day. The national average is currently 142 litres, so we have a way to go. Reducing water use, both cold and hot, reduces greenhouse gas emissions created by water processing and heating, so there is a double benefit. Voluntary schemes have not worked. Research and evidence from schemes already in place have shown that mandatory water efficiency standards and labelling water-using products could reduce household consumption by as much as 20%. It is a no-brainer and has been for 15 years or longer. Pushback from the manufacturers needs to be put in its box and there needs to be better join-up between Defra and BEIS. I ask the Minister to just do it.
Smart water metering is in that category too, having been shown to deliver significant water savings of around 17%. Meters can help water companies to detect and fix leaks, and customers to understand and manage their water use and reduce their carbon impact. At the current rate of water meter rollout, we will reach only 83% of homes by 2045, which is not exactly speedy; we need 1 million smart meters a year. Reducing water demand means avoiding environmental damage and the high cost to consumers from major water infrastructure, such as reservoirs. You know it makes sense, Minister; accept this amendment and just go for it.
