The schools will be tested over the next year to ensure that the drinking-water and irrigation pipelines are clearly separated. To do this, each water supply has to be run separately to be tested to make sure there is no crossover between the lines. Santiago High, one of the 14 schools, used on average 2.7 million gallons of water a month for irrigation, costing about $5,900. The school will save approximately $15,000 a year in water bills through the recycled water program. Source: Water Technology Online |
