Item 19: Phase 1, Progressive Design-Build Services for the design of the FM 1978 Water Reclamation Facility

[COSM_Admin]

Consider approval of Resolution 2025-125R, approving a contract with Burns & McDonnell Engineering Company, Inc. to provide Phase 1, Progressive Design-Build Services for the design of the FM 1978 Water Reclamation Facility project in the estimated amount of $3,518,405.00; authorizing the City Manager, or her designee, to execute the contract on behalf of the city; and declaring an effective date.

Pg.557 - Odor Control & on pg. 558

• How is value defined in these scenarios?
  • “3.2.4 Odor Control The DB will consider alternatives for controlling odor from the lift station. The City has a preference for biological odor control processes, but is willing to consider other processes that can provide the best value for the City.”
  • “The DB will not consider secondary treatment processes that utilize membranes. Proposed design alternatives will seek to balance energy efficiency with the ease of operation in both the selection of treatment processes and aeration equipment. The City has a preference for a “plug flow” process design, however alternative treatment processes that provide the best value to the City may be considered.”

pg. 562 - Plant Outfall

• Out of curiosity, how will this discharge process work and is this the final map outlining the direction of the process itself?
• On that same page under Hydraulic Assessment there seems to be missing recommendations: “3.14.2 Hydraulic Assessment A hydraulic assessment of the unnamed tributary adjacent to the plant site has been conducted to determine the feasibility of its use as a receiving stream for the discharge of treated effluent. This assessment has indicated insufficient hydraulic capacity in this unnamed tributary and recommends”

RE: Eminent Domain

• ”Eminent Domain” can cause concern sometimes, so any additional information from staff easing any potential concerns is deeply appreciated as this is a critical project for our city.

Thank you!

Please ensure that the problems we had with the current WW plant regarding smell, took YEARS to fix, will not happen this time. I think we allowed something experimental there, that had worked in Europe. It didn't work here. This was worse that the tortilla chip factory because the smell was a wider territory and ALWAYS smelled, not just sometime.

  • Answer: “Best Value” is defined as providing the most advantageous combination of quality, effectiveness, and whole life cost for each element of the design/construction. The city preference gives the design team a starting point, but we will discuss all options throughout the review process and go with the option that is best value, even if it’s not the starting preferred option.

This assessment has indicated insufficient hydraulic capacity in this unnamed tributary and recommends”

• Answer: The recommendation of piping the treated effluent approximately 1,500 linear feet from the treatment plant site to Cottonwood Creek to avoid utilizing the open channel flow through the unnamed tributary, which has insufficient hydraulic capacity. The Texas Pollutant Discharge Elimination System (TPDES) discharge permit application has been submitted to the Texas Commission on Environmental Quality (TCEQ) identifying the pipeline in lieu of the unnamed tributary to Cottonwood Creek. 3.14.3 requires that the DB, “consider alternatives necessary to discharge treated effluent from the Facility in a manner consistent with the approved TPDES permit.” We are acquiring a wastewater easement for this treated effluent pipe to discharge directly into Cottonwood Creek.

RE: Eminent Domain

• ”Eminent Domain” can cause concern sometimes, so any additional information from staff easing any potential concerns is deeply appreciated as this is a critical project for our city.
• Answer: Understood. We have a separate agenda item to contract legal support services for the eminent domain process. We’ve successfully negotiated agreements with all landowners for the required fee simple purchases and wastewater easement associated with this project and we are going to utilize eminent domain through friendly condemnation to, “quiet the title” on all transactions. All the properties that are needed have clouded title and we can use eminent domain, with landowner knowledge, to resolve the title issues and close with title policies.

Answer: Yes, we will ensure that we avoid that technology and deliver an odor control technology and process that is effective and reliable from the beginning on this plant operation.
