About this file
This document is an optimization project list for the NCC (likely a water or wastewater treatment facility) that outlines capital upgrade recommendations and associated costs. The technical review team has identified multiple infrastructure improvements necessary to enhance operations and reduce operations and maintenance costs. Key projects include pipe burst trenchless installation of the influent pipeline (6,500 feet), replacement of flow meters, Gregory Gulch reconstruction to minimize sediment buildup, mix tank replacement or modification for improved pH control, installation of an isolation valve, and procurement of internal jetting equipment for maintenance activities. The primary infrastructure project involves replacing a 12-inch corrugated metal pipe (CMP) using pipe bursting technology, with alternative options including manhole insertion and replacement. Additional recommendations focus on instrumentation upgrades, pH control system adjustments, and equipment modifications to optimize facility performance. No specific quantities, response dates, due dates, or bidder meeting information is provided in this document.
The total estimated project cost is $2,268,005, with individual project estimates ranging from $2,000 for isolation valve installation to $2,031,068 for comprehensive pipe burst and infrastructure upgrades. Cost breakdowns include engineering support, survey work, permitting, traffic plan development, equipment procurement, labor, and contingency allowances (typically 10 percent) plus five percent markup on various line items. The document references specific vendors including Brute Jetters, Outlook Enterprises Inc., and Browns Hill, and includes research from commercial sources such as DuraCable and Grainger for equipment pricing. No information is provided regarding funding sources, set-asides, incumbent contractors, contract term, renewal options, or site visit scheduling.

Recommendation Equipment necessary Estimated Cost Source Notes
For long-term operations, the technical review team recommends a review of the existing collection system infrastructure to identify potential capital upgrades for implementation to improve operations and reduce O&M costs. The upgrades would include improved access and modifications to prevent or reduce potential for plugging in the collection system.

The technical team recommends replacing the existing mix tank with a smaller and more appropriately sized unit is likely required for better pH control to allow operations at this lower pH setpoint.
As an alternative, the technical review team recommends reviewing the pH control loop and potentially making adjustments to reduce pH fluctuations.
Replacing the existing lime mix tank in the lime silo with a smaller and more appropriately sized unit is likely required for better pH control and to allow switching to a lime slurry feed system.
An isolation valve is recommended to be installed above the mix tank.
The technical review team recommends that the site team consider procuring new jetting equipment so smaller flushing activities can be performed by operations/maintenance personnel, thereby limiting contractor effort for off-site jetting of source lines and for
