<br />Louisville Water Conservation Goals: <br /> <br />While the City of Louisville continues to pursue additional water supplies to meet future <br />needs, the primary goal of the Louisville water conservation plan is to focus on in- <br />creasing overall water use efficiency system wide. By increasing efficiency for any given <br />water use, water conservation is the direct effect With conservation comes additional <br />supplies that can be put to other uses as may be needed for future growth or drought pro- <br />tection. <br /> <br />The City of Louisville currently projects a gross raw water demand of approximately 4400 <br />acre feet (1.4 billion gallons) for the 1996-1997 water year, and a projected ultimate de- <br />mand of approximately 8200 acre feet (2.7 billion gallons) per year by the year 2015. <br /> <br />Approximately ten percent of the current raw water demand is lost to the storage, convey- <br />ance and treatment processes leaving the remaining ninety percent for distribution to the <br />consumers. <br /> <br />In the case of residential water use, approximately fifty five percent of the water delivered <br />to the system is consumed by so called outside uses such as lawn irrigation, and car wash- <br />ing while the remaining forty five percent is consumed by inside uses such as toilet flush- <br />ing, clothes and dish washing, cooking, bathing etc. In the case of commercial and indus- <br />trial consumption the uses vary widely as a function of the type of business involved. By <br />improving water use efficiency in all possible aspects of the water supply process, from <br />storage and conveyance to distribution and finally consumption, significant water savings <br />can be reco gnized. <br /> <br />Louisville developed a comprehensive Raw Water Master Plan in 1992 which recognized <br />water conservation as a key component in the City's water supply planning process. The <br />City's Raw Water Master Plan identified conservation measures that targeted a conserva- <br />tion goal of five percent for indoor water use and six percent for outdoor water use for a <br />combined goal of five and one half percent of the total raw water annual demand. With <br />continued implementation of current conservation measures as well as implementation of <br />future measures total savings of 5.5 percent are significant, yet realistic. Furthermore as <br />new programs are developed and implemented while existing programs become more ef- <br />fective, savings beyond the goal of 5.5 percent may be possible. <br /> <br />2 <br />
