Metropolitan Utilities District currently charges residents in Omaha $1.23 per cubic feet of water use for each home's first 900 cubic feet of water used, $1.73 per cubic feet of water use for each home's usage rate between 900 and 3,000 cubic feet, and $2.22 per cubic feet of water use for anything over 3,000 cubic feet of use. The pricing structure is an example of:
O conservation pricing.
O too few water permits being traded on the local water market.
O over-use and inefficient pricing.
None of these.
