Such programs may include <br />education programs, incentives and rebates, fixture replacement programs, <br />audits, and conservation rates and surcharges. Emergency conservation <br />programs and drought-response restrictions are not included as long-term <br />water conservation programs. <br />As might be expected, the implementation of water conservation programs <br />varies by provider service area throughout Colorada Many factors are <br />typically considered in evaluating the impact of active conservation <br />36 V.
