Sewer System Optimization for California Facilities

California Sewer Infrastructure Optimization

California's sewer systems represent a critical component of the state's water infrastructure. From the Central Valley farming communities to the dense urban networks of Los Angeles County and the San Fernando Valley, efficient sewer operation directly affects public health, environmental compliance, and operational budgets.

The California Wastewater Process Optimization Program (CalPOP) specializes in identifying and implementing energy savings opportunities within sewer and wastewater treatment processes. Our CPUC-funded program has helped more than forty California facilities since 2001.

Sewer System Challenges in Southern California

The Los Angeles basin and surrounding regions face unique sewer system challenges driven by geography, climate, and aging infrastructure:

• Aging clay and cast iron pipes — much of LA County's sewer infrastructure dates to the 1940s–1970s, with significant deterioration and capacity limitations
• Grease accumulation — the region's restaurant density and warm climate accelerate FOG (fats, oils, grease) buildup in commercial sewer lines
• Infiltration and inflow — seasonal rainfall and groundwater fluctuations increase hydraulic loading on sewer treatment plants
• Seismic vulnerability — the Northridge earthquake (1994) caused extensive hidden damage to underground sewer infrastructure across the San Fernando Valley
• High aeration energy costs — biological treatment processes at wastewater plants are among the largest energy consumers in municipal operations

CalPOP Sewer Optimization Solutions

Aeration System Optimization

Aeration is typically the largest energy consumer at wastewater treatment plants. CalPOP's engineering team analyzes dissolved oxygen profiles, blower performance, and diffuser efficiency to implement aeration cycling programs that dramatically reduce energy consumption without compromising treatment quality.

High-Efficiency Blower Upgrades

We have implemented blower upgrades ranging from small installations at rural lagoon facilities to a 400 HP high-efficiency blower upgrade for a large coastal community — all covered under Program funding.

Process Control Improvements

Modern SCADA and process control systems enable real-time optimization of sewer treatment processes. CalPOP helps facilities implement appropriate control systems tailored to their scale and operational requirements.

Residential Sewer Services in Los Angeles

For homeowners and property managers in the Los Angeles area dealing with sewer line issues — from root intrusion to pipe corrosion — professional sewer inspection and repair services are essential to protect your property and comply with local regulations.

The San Fernando Valley and Burbank area have extensive sewer infrastructure from the post-war development boom. Many homes built between 1945 and 1975 still have original clay or Orangeburg sewer pipes that are approaching the end of their service life.
