Wastewater Trunk Line Through San Martin
Wastewater from the City of Morgan Hill travels in a wastewater trunk line through San Martin to the Wastewater Treatment Plant located in the City of Gilroy, where it is treated and discharged. This plant is owned and operated by the South County Regional Wastewater Authority (SCRWA), under a Joint Powers Agreement with the Cities of Morgan Hill and City of Gilroy.
The trunk line travels through the area of San Martin south of California and north of Day Road, west of Monterey Road and east of Santa Teresa.

The City of Morgan Hill has the sole responsibility for the maintenance of the trunk line heading south until Highland Avenue. South of Highland Avenue the maintenance of line is shared.

Significant Rain Storm Events
During significant rain events the wastewater trunk line running through San Martin can become overwhelmed due to infiltration of the wastewater system. This can cause the trunk line to overspill in the area on Harding Avenue between Cox and Highland. This can cause sewage to spill on to properties adjacent to this area.
The City of Morgan Hill Wastewater Team closely monitors the entire City wastewater system, including the trunk line running through San Martin, leading up to and during significant rain storms. Crews are made ready to respond, if necessary, and bypass pumping equipment is ready to deploy and sometimes staged on site in preparation.
In the event of a spill the City of Morgan Hill Wastewater Team works diligently to first contain and sewage released and then to clean any area impacted. Notification is made to the appropriate agencies as required.
If you suspect a wastewater spill please call the City of Morgan Hill Non Emergency Police Dispatch Number at 408-779-2101.
