Infrastructure Improvements

Water utility services for the Tesoro Viejo community are provided by the Tesoro Viejo Master Mutual Water Company. Cal Water, serving California since 1926, will be operating and maintaining the water, wastewater, recycled water, storm water, and agricultural water systems on TVMMWC's behalf, and will oversee installation of capital improvements to expand the utility systems.
