County of Madera


Maintenance District 10A, Madera Ranchos

MD-10A Alerts and Updates:

Maintenance District 10A, Madera Ranchos, is located in the area of Avenue 12 and Road 36 in Madera County. The district provides water service to over 900 active connections, including approximately 41 businesses. In addition, there are about 95 remaining standby connections. Water is supplied by three of the five available wells from an aquifer approximately 400 feet below the surface. The combined production of the wells in use is approximately 2100 gallons per minute.

The system was taken over by Madera County in 1996. Since that time, we have drilled two wells (and hope to add a third by summer 2006), installed several fire hydrants, one backup generator and over two miles of pipe to relieve low-pressure conditions. Of the wells not currently in use, the Sparta well tests high in Nitrates, and the Fernwood well has tested positive for bacteriological contaminants. Chlorination of the system is required only if the Fernwood well is pressed into use during peak summer-use periods. Otherwise it is not chlorinated.

The distribution system is steel, asbestos cement and plastic pipe. All recently installed piping has been plastic. The majority of the distribution system runs across easements in back yards at or near the property lines. Maintenance and repair of these lines has proven challenging from the standpoint of accessibility, dogs, landscaping and other encroachments onto the easement.

Madera County Engineering Department routinely monitors for contaminants in your drinking water according to Federal and State laws. Our constant goal is to provide you with a safe and dependable water supply. A Consumer Confidence Report is prepared annually and delivered to all residents served by the water district. These reports, prepared especially for this district, are available for viewing below. Adobe Acrobat Reader, which may be downloaded free of charge from Adobe�s website, is required to view and/or print them. Be aware that there is a one year lag time in these reports; i.e., the report dated 2004 contains test results collected in 2004, but the report is not written or released until approximately June, 2005. Future dates will be posted as they become available.  

To report an after hour or holiday emergency relating to your sewer or water service in the districts listed above, please contact the Sheriff’s Department at (559) 675-7769 for Valley locations, or (559) 642-3201 for Mountain locations.  During office hours, please contact the Special Districts Division directly at (559) 675-7820.

If you have any further questions regarding this service area please contact the Madera County Resource Management Agency, Engineering and General Services Department, Special District Division at (559) 675-7820.
