South Lakeport Wastewater Service
The South Lakeport wastewater collection system serves customers in AD 9-1 and AD 9-3, from Lands End, and portions of the Big Valley Rancheria, Soda Bay Road and S. Main Street. Raw wastewater is conveyed through a series of lift stations and the collection system . The wastewater is treated at the City of Lakeport’s Wastewater Treatment Facility through a formal agreement between the two agencies.
Customer Statistics and Infrastructure
AD 9-1 and AD 9-3/ South Lakeport currently includes:
- AD 9-1: 142 service connections (153 Single Family Dwelling (SFD) equivalents) serving approximately 446 residents;
- AD 9-3:54 service connections (80 SFDs), serving commercial establishment and approximately 24 residents;
- 70 manholes (40 – AD 9-1, 30 - AD 9-3) and over 5 miles of pipe within the gravity collection system.
- 5 lift stations (3 in AD 9-1, and 2 in AD 9-3) and over 2 miles of force main piping conveying wastewater flows to the connection point with the City of Lakeport’s wastewater collection system.
The South Lakeport collection systems were originally constructed 25 years ago. The 12-month averaged increase in the AD 9-1 and AD 9-3 customer base averages less than 1%.
The District continues to implement Infiltration and Inflow (I/I) mitigation, and will be investigating any sources of excess flow within these portions of the collection system. Costs for treatment are paid to the City of Lakeport through metered flow measurements. Costs for treatment continue to rise and the elimination of excess I/I is a priority. A rate increase was implemented recently to help pay for increase operation and maintenance costs.
