Hydrologic Cycle

Development Changes Hydrologic Cycle

Barriers to acceptance of Water Conservation Potable water revenue pays for centralized water centralized wastewater, and extras? City raw water contracts - take or pay Balance of water use reduction with demand increases Can we be too successful?????
