Lord Blencathra (Con)

My Lords, I thank my noble friend for tabling her amendments in this group. I know that the whole House respects her for her commitment to the issue of sustainable drainage, and I pay tribute to her for her persistence in raising this particular matter, because it is about time that we made some progress on it. Our water system is put under pressure when developments are built out and connected up, and my noble friend is right to raise this. Can the Minister please take this opportunity to set out the Government’s ongoing work on delivering a sustainable future for our water systems? We would also be interested to hear what active steps the department is taking to engage with the development sector, including small and medium-sized developers, to ensure that existing non-statutory standards for sustainable drainage have been implemented. My noble friends have mentioned 2010. I can beat that. I think it was in 1992 that, as Environment Minister, I was shown a revolutionary new system whereby the downpipes from our houses are connected to a soakaway and a system of seepage pipes about a foot underground, where the water then slowly leaked back into the soil. For big commercial car parks, the seepage pipes were put down a metre, so they were not crushed. Those systems were in development then, and I said, “This is a jolly good idea, we should do it”, but the word was, “Oh no, Minister, it is not quite the right time to do it yet”. So I would be interested to hear what the Minister can say about that particular area. What development work is going on for seepage systems in ordinary domestic houses? We have millions of gallons of pure raindrops falling on our roofs, we put it into the sewerage system and then the water companies spend millions of pounds taking out the clean water again. Seepage systems must be the way to go in the near future.
