Brush Creek Pump Station Improvements Project

Brush Creek Pump Station

Notice of Non-Mandatory One-on-One Meetings with Engineers and Contractors

Non-mandatory one-on-one meetings with Engineers and Contractors for the Brush Creek Pump Station Improvements Project were held June 8 – June 12.  A PDF of the agenda for the meetings is attached. 

The Brush Creek pump station preliminary engineering report (PER) was originally completed by HDR in August 2022 and updated in 2026 to incorporate the current wet weather forcemain plan, project cost estimate, and schedule.

​

Total projected project cost: $12 - $17 M.

​

The PER determined that the pump station will need to be replaced and will have:

  1. Influent screening

  2. Sized for dry weather and wet weather conditions

  3. Installation of dry weather submersible pumps

  4. Odor control

  5. Electrical and control room

  6. Site work and landscaping

 

The pump station is located by a city park in a residential area. Community outreach and close coordination with the City will be important.  

​It is JCW’s desire to use collaborative delivery, preferably progressive design-build; this is pending Board review and approval.
