Summary: At the Warren Facility, the secondary treatment process produces high-quality,
permit-compliant treated effluent and consists of eight treatment trains (A-H), with each train comprising
an aerobic biological reactor followed by 26 final clarifiers. Since its construction in 1977, Secondary
Treatment Train A has experienced progressive concrete deterioration. This project will rehabilitate
deteriorated concrete throughout Secondary Treatment Train A, restoring the structural integrity of the
facilities and ensuring the long-term reliable operation of the secondary treatment process and continued
compliance with the Warren Facility's effluent discharge permit limits. Pursuant to authority previously
granted by the Board, the project will be completed utilizing the Job Order Contracting Program, which
relies on pre-established, competitively-bid construction tasks that will accelerate project delivery and
reduce administration and design costs. Staff has determined that the activities described are not subject
to the provisions of the California Environmental Quality Act (CEQA). The activities described herein
do not constitute a “Project” as that term is defined in California Public Resources Code Section 21065
and Title 14 of the California Code of Regulations (“CEQA Guidelines”) Section 15378. This item is
consistent with the Districts’ Guiding Principles to protect financial and facility assets through prudent
investment and maintenance programs; and commitment to operational excellence (protection of public
health and the environment, regulatory compliance, and cost effectiveness).

Summary: Annually, the Districts reviews approximately 350 miles of CCTV inspections of its sewers
for condition assessment and to prioritize sewer rehabilitation capital improvements. In June 2025, the
Districts’ video inspection processing work was consolidated under the WinCan software suite to
increase efficiency by eliminating the need to convert and transfer videos from one format and platform
to another. Over the past year, WinCan has consistently provided high-quality support services and has
demonstrated a strong understanding of the Districts’ CCTV inspection program requirements. Their
performance has been instrumental in reducing the backlog of sewer video inspection reviews. In
addition to their technical capabilities, WinCan has been responsive, reliable, and collaborative in
addressing project needs and operational challenges. Districts’ staff has been satisfied with WinCan’s
overall performance and recommends approval of this sole-source purchase order for another year’s
worth of CCTV software and inspection support services to ensure continuity of services, maintain
progress in inspection review efforts, and provide essential support for the Districts’ sewer condition
assessment and capital improvement programs. This item is consistent with the Districts’ Guiding
Principles to protect financial and facility assets through prudent investment and maintenance programs;
and commitment to operational excellence (protection of public health and the environment, regulatory
compliance, and cost effectiveness).

Summary: The Secondary Influent Pump Station (SIPS) is a critical pump station that utilizes five
engine-driven pumps to convey primary effluent from the Primary Treatment process to the Secondary
Treatment process. In September 2022, SIPS Pump No. 3 failed due to a broken shaft. The failed pump
was subsequently replaced with one of two new pumps procured in 2023. To maintain the reliability of
the pump station and reduce the risk of future failures, it is recommended that the remaining four pumps,
including SIPS Pump No. 2, be replaced on a phased basis with new or rehabilitated pumps. As the next
phase of the rehabilitation program, staff recommends that Flowserve remove the existing pump at SIPS
Pump No. 2 and install the remaining new replacement pump. The other three pumps will be replaced
with rehabilitated pumps in future phases to ensure the continued reliable operation of the SIPS, which is
essential for conveying primary effluent to the secondary treatment process and maintaining compliance
with the Warren Facility's effluent discharge permit limits. Flowserve is the original equipment
manufacturer and the sole authorized service provider for these pumps. This recommendation is
consistent with the Districts' Guiding Principles to protect financial and facility assets through prudent
investment and maintenance programs; and commitment to operational excellence (protection of public
health and the environment, regulatory compliance, and cost effectiveness).
