The storage and distribution system utilizes two storage tanks, three booster pumps, and a system of pipes and valves which deliver the water to users. There is also a system of water hydrants to provide water for fire protection. Click on the "Storage and Distribution" link to learn more about this system.
North Star Engineering provided the Board of Directors with an Engineer's Report in 2004 and another Engineering Report in 2007. The purpose of this report was to evaluate the system.
Inspection Reports are from the Butte County Health Deptment which enforces the clean water laws. The older inspection reports show the many problems with the system before the imporvements. The 2010 Inspection Report shows that all the major problems have been fixed and the system has good capacity and an excellent record of performance.
