CLEAN WATER SERVICES

Cleaning used water takes a lot of energy, but we generate some of our own from renewable sources (cogeneration of fats, oils and grease and methane gas from our digesters) and from solar panels. We meet about 37 percent our electricity needs through these methods... We recover and reuse several nutrients through the treatment process. Solids that settle out during primary and secondary treatment are routed to digesters where they are heated and mixed for about a month, resulting in 31 dry tons a day of nutrient-rich biosolids that are used as a soil amendment on local farms and rangeland. Our larger facilities process phosphorus and other nutrients into a slow-release fertilizer.
