I believe the most important part of the plan is reduction in leakage. Leakage is expensive as it it is usually finished product which we have all paid to be processed. The increase in water metering points is vital if you are to identify leaks and general leak locations. Of course this can be most effective if metering is online IE dynamic. Speed of leak identification and determination of leak location will save everyone money.

We made this leakage/usage monitoring suggestion to Yorkshire Water circa 1990. At the time they were losing a great deal of finished product.
It will most efficient if in addition to regional metering, all water usage is also metered at point of use, not only tp pinpoint leaks but to identify leaks off your system on customer premises. 

I wish you every success
