What We Do
The Department of Water Resources and Conservation provides comprehensive and integrated management of Petaluma's water resources. Delivery of potable water and collection and treatment of wastewater are conducted 24 hours a day, 365 days a year.
Water purchased from the Sonoma County Water Agency is distributed to the City's customers through seven pump stations and 11 storage tanks/reservoirs. The Utility Operations and Maintenance Division continually monitors and adjusts the pressure and flow of water to meet customer demands.
After the water is used and discharged by the City's customers, it is collected through an underground network of over 200 miles of collection system pipeline. A system of nine collection system pump stations pumps the wastewater to the City's wastewater treatment facility. After receiving secondary treatment, the wastewater is discharged to the Petaluma River during the winter, and recycled during the summer for irrigation of 800 acres of agricultural land and a golf course. The City recycles approximately 50% of its annual average dry weather flow of wastewater.
Surface water management is achieved through a network of natural creeks, mechanized channels, and storm drains which flow to the Petaluma River. To meet federal regulations, upgrade and improve the surface water infrastructure, and help protect the Petaluma River, the Department of Water Resources will be expanding its surface water management program.
