Three weeks ago, I asked my noble friend what was happening to change building regulations to reduce the volume of water needing disposal, which would thus be an advantage with things such as storm overflows. My noble friend told me that there were discussions going on, but I realise that this is a cross-cutting matter between departments, and that always makes me nervous. I wonder whether my noble friend would write to me, and put a copy in the Library, about exactly what discussions are going on and what plans there are to change building regulations to reduce the capacity of water, and with some sort of timetable that is being given to developers to make sure that it is complied with.
Lord Benyon (Con)
This comes down to the thorny issue of nutrient neutrality. The problem that we have in this country is that most of our houses have mixed clean water and dirty water going into the same sewer. This is what is causing the problems in the sewage overflows. We have a new legal duty on water companies in England to upgrade wastewater treatment works. A new nutrient mitigation scheme established by Natural England is helping wildlife and boosting access to nature. But the cost to retrofit a separated system would be somewhere around £345 billion to £600 billion, which would be quite a considerable hit on individual households. But there has to be a plan to resolve nutrient neutrality, or the backlog of houses that are needed by people will not be able to be built—so I will certainly write to my noble friend.
Water Companies: Pollution

Lord Benyon (Con)
I am very pleased to make the noble Baroness’s day by saying that we have increased a thousandfold, from £250,000 to £250 million, the upper limit on which water companies can be fined.
Baroness Browning (Con)
My Lords, have the Government given consideration to changing the building regulations, particularly with regard to rainwater run-off, so that the water is recycled and not taken into the system, thus reducing the volume going out of the system?
Lord Benyon (Con)
My noble friend is absolutely right to raise this. One of the problems is that water coming off roofs and driveways—absolutely clean water—goes into the same sewerage system. To separate foul water from clean water has been estimated at costing between £350 billion and £600 billion, which would have a dramatic effect on people’s bills. However, there is nothing to stop us trying to do this with new housing, as well as retrofitting it into existing housing, and ongoing discussions are taking place with other government departments to see if this can happen.
