Extreme Sewer Makeover
Los Osos, California, is an unincorporated community of approximately 5,000 homes and 15,000 residents situated on the coastline of San Luis Obispo County. The area became a subdivision in the late 19th century and was developed for summer homes and retreats.
Initially, sanitation needs were met primarily through individual septic systems, many on densely developed small lots, often within areas of high groundwater. Due to concerns of failing systems, and a measurable increase in pollution within the community’s groundwater supply, a completely new sewer system was deemed necessary. Once fully operational, this new collection and treatment system will reduce environmental impacts, recycle wastewater, and help restore the aquifer as a healthy source of drinking water for the community.
