c. Recyclinq and Reuse: A city or utility should evaluate the potential of recycling and reuse because these methods may be used to increase water supplies in the utility's service area. Reuse can be especially important where the use of treated effluent from an industry or a municipal system or agricultural return flows replace an existing use that currently requires fresh water from a city's or utility's supply. Recycling of in- plant process or cooling water can reduce the amount of fresh water required by many industrial operations. Currently, the City of La Porte has a water reuse program. Because of its size and daily flows, the reuse of treated effluent for processed water has proven quite economical for the City of La Porte, with an estimated three million gallons per month being used for this purpose. The City of La Porte's Municipal Golf Course along with one of the City parks, Little Cedar Bayou, are irrigated with plant effluent. This resulted in a savings of approximately 60,000,000 gallons of potable water in 2005. F. PLAN OBJECTIVES .:.
