The Policy Shift
In October 2024, the Los Angeles City Council approved a 22% sewer service rate hike, the largest single adjustment in years. Additional smaller sewer increases are planned through 2028, with the typical bi-monthly residential sewer bill projected to reach $155.48 by July 2028. Simultaneously, the Los Angeles County Waterworks Districts are seeking approval for a five-year financial plan with water rate increases starting January 1, 2026. These annual adjustments can reach up to 15% in any calendar year, intended to cover inflation and wholesale water cost increases. Together, these two programs create a compounding effect on commercial water costs.
The Math: Commercial Financial Impact
Using SmartValve's integer-math billing engine, we modeled a baseline commercial facility consuming 300 kGal per month in Los Angeles. Current combined rate: $24.93/kGal (water $14.97/kGal weighted average + sewer ~$9.96/kGal). Post-sewer-increase combined rate: $27.12/kGal (22% sewer hike: $9.96 → $12.15/kGal + water unchanged for this calculation). Previous monthly volumetric cost: $7,479 ($24.93 × 300 kGal). New monthly volumetric cost: $8,136 ($27.12 × 300 kGal). That is a $657/month increase, or $7,884 per year in additional operating expenses from the sewer hike alone. When the County's water rate increases take effect in 2026, the total impact will be even higher.
Why This Is Happening
Los Angeles has one of the largest and oldest wastewater systems in the nation. One-third of the city's sewer pipes are over 90 years old, requiring urgent replacement and rehabilitation. The 22% sewer rate hike funds critical repairs and upgrades to prevent system failures, environmental violations, and public health risks. The parallel water rate increases from LA County Waterworks reflect rising wholesale costs from the Metropolitan Water District and the need to fund infrastructure modernization across the county's waterworks districts.
Mitigation Strategy
Los Angeles commercial operators face a dual cost squeeze from simultaneous sewer and water rate escalations. At $27.12/kGal combined (and rising), facilities consuming above 200 kGal/month should evaluate air compression valve technology (Smart Valve), which reduces metered volume by 15-25%. At the new rate, a 20% volumetric reduction on a 300 kGal facility saves approximately $19,526/year. This is particularly impactful in LA because sewer charges are typically calculated as a percentage of metered water consumption — reducing metered water automatically reduces sewer costs too.
Calculate your LA facility's total water + sewer cost exposure under the new rates.
The Smart Valve compresses air in your water line, ensuring you only pay for actual liquid and stay under penalty thresholds.

How much did LA sewer rates increase in 2024-2026?
The LA City Council approved a 22% sewer service rate hike in October 2024, with additional increases planned through 2028. For a commercial facility using 300,000 gallons per month, the sewer increase alone adds approximately $7,884 per year in operating expenses.
Are LA water rates also going up?
Yes. LA County Waterworks Districts are implementing a five-year water rate plan starting January 1, 2026, with annual increases of up to 15%. Combined with the 22% sewer hike, commercial operators face compounding cost increases through 2030.
Why are Los Angeles sewer rates increasing so much?
One-third of LA's sewer pipes are over 90 years old and require urgent replacement. The 22% rate hike funds critical infrastructure repairs to prevent system failures, environmental violations, and public health emergencies across the nation's second-largest city.
