PUBLIC WORKS DEPARTMENT
Mark Houghton, Public Works Director
Sewer Division

Sewer Division's Major Functions:

  • Sewer Lift Station and Sewer Collections: Maintain sewer line infrastructure integrity and sewage transportation reliability, under the Waste Discharge Regulation (WDR)
  • Sewage Treatment: Treat, analyze and discharge treated wastewater and solids in compliance with Federal and State regulatory requirements.
  • Storm Water Management: Follow Best Management practice to prevent and minimize stormwater from street damming through storm drainage, retention and pump station reliability.

Laboratory


The laboratory serves the City of Manteca by providing quality, certified data for the Wastewater Division, Water Division, and the Industrial Pretreatment program. Data produced satisfies California State and Federal monitoring requirements for Drinking Water, Wastewater, and Industrial permits. Process control data (see Note) is also supplied to both Water and Wastewater Divisions as they strive to provide quality drinking water and highly treated wastewater effluent.

Note: (Process control data is the analytical data used for determining directions for operational steps.)

Operations

State Discharge regulatory permits dictate operational treatment and compliance requirements. The Operations team is required to monitor, analyze, configure, adjust, and redirect sewage treatment flow, treatment structures, pumps and equipment to ensure proper process control and meet regulatory discharge permit compliance.

Maintenance


The maintenance team's primary goal is to ensure that each Sewage Lift Station, Storm Water Pump Station, and all sewage treatment instrumentation, electrical, and equipment are maintained for reliable mechanical performance.

Collections / Storm Water


The sewer collections and stormwater team spend the majority of their time at various locations throughout the City of Manteca. Their objectives are to ensure that the collections / stormwater infrastructure are maintained to ensure liquid flow movement throughout the system.

Regulatory Permits


The Water Quality Control Facility must comply with the following regulatory permits:

Reclaimed Water Facilities Master Plan

The City of Manteca proposes to develop a Reclaimed Water Facilities Master Plan to provide the City with a plan to systematically develop and implement the use of treated wastewater from the Manteca Water Quality Control Facility. The City of Manteca Wastewater Master Plan, adopted in 2004 (updated on 2012) and the 2005 Water Master Plan include the future use of reclaimed water to aid in the disposal of wastewater and to reduce potable water demand. The Reclaimed Water Facilities Master Plan is to provide the City with a planning document for the phased development and use of reclaimed water over the next 20 to 25 years.

The Manteca Wastewater Quality Control Facility (WQCF) is located on 210 acres of City owned property southwest of downtown Manteca at 2450 West Yosemite Avenue. The WQCF treats typical municipal wastewater generated in the City of Manteca and the neighboring City of Lathrop.

The Manteca WQCF is a 9.87 MGD average day dry weather (ADWF) rated, activated sludge plant with denitrification. The WQCF consists of an influent pump station, aerated grit tanks, primary sedimentation basins, fine-bubble activated sludge aeration basins, secondary clarifiers, secondary effluent equalization pond, tertiary filters, UV disinfection and effluent pumping station. Secondary effluent is land applied during the spring and summer. Tertiary filtered and UV disinfected water is discharged to the San Joaquin River during the winter.

The Wastewater Master Plan projects a capacity requirement of 27 MGD ADWF at buildout for the WQCF. Expansion of the WQCF to buildout will occur in two phases, which will increase the ADWF capacity to 17.5 MGD and 27 MGD. The Wastewater Master Plan projects a potential reclaimed water use of 3.28 MGD. The 2005 Urban Water Management Plan projects reclaimed water usage of 2 MGD by 2030.

Public outreach meetings will be held throughout the process of developing the Reclaimed Water Facilities Master Plan to provide information and obtain feedback. The group meetings will include major stakeholders and the general public, as well as having City Council presentations. The Notices will be posted below with Location, Date, and Time.

Multi-Agency Post-construction Standards (LID)

The City of Manteca, in collaboration with San Joaquin County, Tracy, Lodi, Lathrop, and Patterson will be preparing Multi-Agency Post-Construction Development Standards to provide consistent guidance for municipal workers, developers and builders working in the region in implementing the requirements under the Statewide Small MS4 NPDES permit (2013-0001-DWQ). The development standards, also known a post-construction stormwater requirements, will become part of each Partners land development process. The Standards will provide guidance source control, site design, low impact development, stormwater treatment and hydromodification management measures. These new requirements will change, and are intended to improve, the way we build or re-construct our community to better manage our stormwater resources in the future. To facilitate the preparation of these Post-construction Development Standards, the City of Manteca, and its partners, will be holding stakeholder meetings and providing draft documents for review from which we are seeking to receive comments and feedback from the community and interested parties. Multiple stakeholder meetings will be held through-out the process of developing the Standards. It is intended that the stakeholder process will provide opportunities for interested stakeholders to learn about the regulatory requirements, provide input and comments, and otherwise help inform the development of the Standards.
