Our Services - LA County Public Works

The Budget Unit is responsible for preparing and managing approximately $43.8M annual budget and conducting the necessary studies of short term and long range needs for the Sewer Maintenance Districts and 11 Special Zones.

This unit is responsible for processing of purchase orders for equipment and supplies and for approving invoices, and processing of utility bills for the numerous Districts facilities for payment.

This team is responsible for the Divisions’ State General Waste Discharge Requirements (WDR’s) compliance activities including, Sewer System Management Plan (SSMP) development, monitoring, and updating, and for Sanitary Sewer Overflows reporting and certification. The team is the liaison between the Department and the 42 cities currently served by the Districts on WDR related issues. The team also provides Data Submitting and Legally Responsible Official (LRO) services to all the cities in the District.

Another part of the Engineering System is the Accumulative Capital Outlay (ACO)/Condition Assessment Unit.

The ACO Program fund was established in 1987 as a mechanism to pay for sewer pipe replacements, relief sewer construction, and major improvements to sewage pumping stations. The objectives of the fund are to establish a charge to be collected from each parcel of real property in the Consolidated Sewer Maintenance District and utilize these monies for sewer line repair and rehabilitation projects. Under this Program, a majority of the pipelines built with Portland cement concrete, which have deteriorated from sewage contact in its 50+ years lifetime, have been replaced with more durable vitrified clay material and/or have been protected by an impenetrable lining material. This lining minimizes the effects of invasive root intrusions and prevents stormwater or groundwater infiltration which compromises the capacity of the lines. These preventative measures will ensure a reduction of sewage overflows in your community. Since its inception, 93 miles of sewer lines have been rehabilitated or reconstructed as part of the ACO Program.

Condition Assessment Unit is responsible for using closed-circuit television to inspect the internal condition and structural integrity of the sewer pipeline. Approximately 500 miles of the sewer collection system will be videotaped each year. To ensure that video quality and inspection data are collected thoroughly and consistently, we utilize nationwide standards developed by the National Association of Sewer Service Companies (NASSCO). Upon completion of the televised inspection, engineering

This unit uses CAD and GIS software to maintain and generate operational maps of over 5,000 miles of sanitary sewers maintained by field crews. The unit also oversees the annexation of new parcels to the Sewer Maintenance Districts. The unit has initiated the digital scanning of existing sewer design drawings for storage in the Department’s Document Management System.

This unit is responsible for monitoring sewer service charges and preparing and submitting annual reports to the Board of Supervisors for over 500,000 parcels of property which are assessed annual service charges. The total annual revenues generated for the maintenance of the Districts and Zones are in excess of $40 million.

Sewer Plan Check Unit is responsible for the review of gravity sanitary sewer and pump station plans and specifications prepared and submitted by professional engineers and consultants for projects in the 42 cities within the Sewer Maintenance Districts. This unit is also responsible for conducting special investigations and reviewing environmental impact reports for projects within the County. Second Unit is responsible for determining if sewer facilities in the area are adequate to meet the demand of the second unit and all other properties served by the same facilities.

The operations unit is given the direst sewer findings from the condition assessment unit, field personnel, and CSMD cities to coordinate for repair. Through our as-needed emergency contract, an emergency repair or lining contractor is chosen to bypass and fix sewers in response times as quickly as a few hours. Our office staff in this section locates as-builts, reviews CCTV, meets on-site, and contacts residents, cities, and sister agencies to ensure smooth and seamless repairs of sewers in need. They cover any urgent sewer repairs from small mainlines in residential backyards to 900-foot-long siphons under rivers.

Our unit specializes in overseeing the entire lifecycle of our Division’s asset improvement initiatives, from initial programming and planning through post-construction phases. Our primary mission is to ensure timely, within-scope, and budget-conscious delivery, maintaining high standards and reliable outcomes for the CSMD facilities and assets we manage.
