Any reduction in water demand through conservation saves <br />taxpayers dollars. <br /> <br />4.3 Effects of Water Use Efficiency <br /> <br />The impact of increasing water use efficiency can be both beneficial and can potentially <br />create problems. Benefits include energy savings; reduced pumping and distribution costs; <br />postpone and or reduce acquisition of further water supplies; reduced potable water <br />treatment costs, and curtails the immediate requirement to build new facilities; and <br />environmental protection by reducing the degradation of surface and ground water levels. <br />Potential problems which can occur include reduction of water utility revenues; risk that <br />conservation would not continue in the future; growth inducement from increased supply; <br />decreasing the ability of the public to save additional water during drought conditions; and <br />alteration of the quality of life for current customers and residents. <br /> <br />4.4 1Lovnn Efforts <br /> <br />Water conservation efforts also apply to the Town of Castle Rock itself. The Town <br />maintains approximately 290 acres of developed park land, common areas, greenways and <br />undeveloped land. The Parks and Recreation Department has implemented procedures to <br /> <br />22 <br />
