Locke, California


Read more about Locke in the Technical Reprints section

Locke is an historic, Chinese-settled town south of Sacramento. The original sewer system, built when the town was founded in 1915, transported wastewater to a septic tank and onto treatment ponds.

The Problem

• An antiquated, undersized sewer system discharged to a community septic tank
• Sewage often flowed to an open field instead of treatment ponds

The Solution

• E/One Sewers eliminated the odor problems cited by residents and still protected the historic character of the town

Locke Today

"The construction caused very little disruption in the historic Locke community because the LPS system is far less intrusive than a typical gravity system … Many of our sewer lines were installed by trenchless (horizontal) drilling, which is impossible when constructing a gravity system." — Michael Meyer, PE, Project Manager for the sanitation district
