RECOMMENDATION
title
Approve and authorize Agreement No. 250439B (LBRID) with Specialized Utility Services Program dba SUSP Engineering for a maximum compensation of $21,780 for video inspection of sewer pipelines. (Fiscal Impact: $21,780 Expense; Lake Berryessa Resort Improvement District; Budgeted; Discretionary)
body
BACKGROUND
Lake Berryessa Resort Improvement District (LBRID) is a special district of the State of California organized in 1965 under the Resort Improvement District Law (Public Resources Code Section 13000 et seq.) for the provision of water and sewer service to Unit No. 2 of the Berryessa Estates subdivision in an unincorporated portion of the County of Napa.
LBRID operates and maintains approximately seven (7) miles of sewer collection mains within the Berryessa Estates. Most of the District’s sewer collection mains are vitrified clay pipe and roughly half of all collection mains were installed out of the public right of way and within private unimproved easements. At LBRID, the pipeline installed in the unimproved easements has historically shown susceptibility to I/I (inflow from stormwater runoff and infiltration from groundwater) either through separated joints between sections of pipe or through cracks in the pipeline that have occurred from root intrusion or ground shift. I/I is a concern because if left unaddressed it increases wastewater flows entering the collection system, potentially overwhelming pumping capacities and/or causing overboard discharges of wastewater to land.
Close-Circuit Television (CCTV) pipe inspection is one method of identifying sections of sewer pipeline that may be contributing to I/I. District staff has identified approximately 11,000 ft of sewer collection main located in unimproved easements that require inspection. District staff requested quotations for CCTV pipeline services from several vendors, and Specialized Utilities Services Program (SUSP) doing business as SUSP Engineering, provided the low quote of $21,780; however, because the District has an ongoing contract with SUSP for operations and maintenance services of the water and sewer facilities, the annual aggregate compensation to SUSP for water and sewer services exceeds the Purchasing Agent limit of $85,300 established by the Public Contracting Code, and Board approval of the contract is required. The District received one additional quotation from Nor Cal Pipelines for $52,990. All other vendors were non-responsive.
Requested Actions:
1. Approve Agreement No. 250439B (LBRID) with SUSP Engineering for $21,780 for CCTV pipeline inspection services.
FISCAL & STRATEGIC PLAN IMPACT
|
Is there a Fiscal Impact? |
Yes |
|
Is it currently budgeted? |
Yes |
|
Is it Mandatory or Discretionary? |
Discretionary |
|
Discretionary Justification: |
A sewer video inspection is a necessary tool used to detect and determine the severity of the common problems in sewer systems - from damaged pipe, separated joints, root intrusion - that can create capacity issues at the sewer plant or backups in the sewer collection system. The sections selected for the proposed agreement are most prone to common pipeline problems due to their location outside the public right of way. |
|
Is the general fund affected? |
No |
|
Future fiscal impact: |
The video services are expected to wrap up in FY 2025-26. |
|
Consequences if not approved: |
The District will be unable to determine if the sections of pipe selected for the agreement are compromised until such time as a sewer back-up occurs over land or the sewer plant is inundated with excess inflows to Lift Station A and treatment ponds. |
ENVIRONMENTAL IMPACT
ENVIRONMENTAL DETERMINATION: The proposed activity is categorically exempt from the California Environmental Quality Act pursuant to CEQA Guidelines section 15301, as the operation and maintenance of existing facilities involving negligible or no expansion of existing or former use.
