With funding from the EPA Targeted Watersheds Grant program, DCR implemented and monitored the performance of nine demonstration projects that highlighted low-impact development and water conservation techniques. The U.S. Geological Survey (USGS) used data collected from the demonstration projects in a watershed computer model that simulated the effect on river flows if these low-impact development and water conservation techniques were to be applied throughout the watershed.
Low-Impact Development Demonstrations
Four projects demonstrated low-impact development approaches and their potential to decrease stormwater runoff and nonpoint source pollution and to enhance groundwater recharge:
Water Conservation Demonstrations
Five projects demonstrated innovative water conservation approaches and their potential to reduce water demand:
5. Rainwater harvesting
6. Soil and turf amendments at municipal athletic fields
7. Water conservation retrofits and appliance rebates
8. Weather-based irrigation controllers
9. Water meter replacements and monthly water billing
These demonstration projects were located in eight communities within the Ipswich River watershed.
