Project Summary

The Ross Creek Sewer Removal project is designed and currently in the permitting phase. The project will remove an abandoned 24-inch diameter sewer from the creek bed of Ross Creek at the Shady Lane bridge. 

In order to minimize upstream erosion, natural rock features will be used to create a sustainable riffle structure in place of the sewer (which was originally installed in 1926 and a replacement siphon was installed 7.5 feet below the streambed in Oct. 2019).


All RVSD projects and work activities being conducted adhere to the District’s COVID-19 Exposure Control Plan to prepare for and, mitigate against the risk of COVID-19 exposure to the District’s office staff and field workers.

These upgrades to old or outdated system infrastructure will enhance local wastewater system reliability and efficiency.

In addition, the abandoned sewer removal from the streambed will have aesthetic benefits of a more natural-looking water feature as viewed from the Shady Lane bridge, as well as the environmental benefits of improving conditions for anadromous fish migration of the native steelhead trout population of the Corte Madera Creek watershed.
