Re: Proposal for Engineering Services
Water Treatment Plant (WTP) - Filter Media Replacement
Prior Lake, Minnesota
Dear Mr. Monserud:
WSB appreciates the opportunity to submit this letter proposal for performing engineering
services for the replacement of the filter media in Prior Lake’s Water Treatment Plant (WTP).
Engineering Services Goal:
Prior Lake’s goal for this project is to successfully replace the filter media in all six (6) of the WTP’s
Filters - with the work divided into two separate construction years, as outlined below.
A. 2025 – Filter Media Replacement
·Filters No. 4, 5, and 6
B. 2026 – Filter Media Replacement
Filters No. 1, 2, and 3
Following each year’s filter media removal, Prior Lake would like the condition of the existing
underdrain system assessed, to ensure that it can remain in place and that the new filter media
can be placed over the existing underdrain block.
Exclusions
Items and work tasks NOT included in the scope of services provided by WSB include:
1) Survey services.
2) Geotechnical services.
3) Permitting. (No construction permit required for maintenance-related work.)
4) Analysis of, and modification to, the existing water distribution system.
5) Change to Filter Backwash or Chemical Feed Programming
6) Evaluation of media tendency to avoid becoming coated with new treatment (bypassing
the aerator and orthophosphate feed location, etc.).
a.Note – these services will be provided separately, as filter evaluation services,
on an hourly rate basis as requested by Prior Lake
7) Any work, beyond inspection, associated with replacing the existing underdrain block and
system.
