My Lords, I thank everyone who has taken part in this debate, which was interrupted, unfortunately, on Monday evening. Like the noble Baroness, Lady Hayman, I was very struck by the speech of the noble Baroness, Lady Young,
about the difference between Scotland and England in the treatment of wastewater. I must admit that I had not known that. I hope that the Minister and his officials will take note of that discrepancy and consider it an additional indicator of how much we still have to do in England to improve our systems.
I am obviously disappointed that the Government are not yet prepared to place an immediate legal obligation on the water companies to begin to improve, and continue to improve, their treatment plants. I am pleased that the Minister has indicated that he is prepared to meet further. It would be helpful if we could find amendments that are more acceptable to the Government, because I sense a strong cross-party consensus in the House that we have to do more than the Bill currently proposes. I particularly hope that the Government will consider doing more along the lines of the amendments of my noble friend Lord Cameron, on nature-based solutions, and the noble Lord, Lord Teverson, on greywater systems.
There were many good parts to this debate, but the best part was the clear recognition throughout the House that we must do more to clean up our rivers. The Minister has mentioned again this afternoon the disturbingly high estimated cost of upgrading the systems: between £200 billion and £500 billion. Obviously, that is an alarming figure. Is he prepared to write to me explaining how that figure was arrived at? Clearly, the country as a whole would have great difficulty financing that. Nevertheless, we must deal with the problem. It has been a helpful debate, along with the debate we had on Monday evening about storm overflows, but in the meantime, I beg leave to withdraw my amendment.
