Mr. Jerry Grant:

They are two different things because district meters measure flows into defined areas that one segregates. What we try to do is break a network up into defined areas of about 1,500 premises and that allows us to target leakage and to prioritise. That is all that does. It does not take us any further. Obviously, domestic metering is about the individual premises and its use. It is probably fair to say, and we will come back to it in the next session, that we have saved approximately 70 million litres a day on domestic premises because of following up the first fix programme.
