RE: |
Wastewater Facilities Master Plan Recommendation |
Project Details
As has been stated
previously, there has been a lot of change since the completion of the 2003 Wastewater Master Plan. Population
growth rates have been less than projected and better technical information is
now available on the location of the wastewater assets and flows in the system.
In addition, millions of dollars in improvements have been completed. A new master plan will incorporate all of this
information to provide a new review and recommendations for improvements to the
wastewater system.
The plan will include a
review of the timing for the construction and initial capacity of the Wakarusa
Water Reclamation Facility (WWRF), a comprehensive Capital Improvement Program
(CIP), a Rehabilitation & Replacement Program (RRP) and a review of the
wastewater rates necessary to support all of these projects. Of most interest
to the Commission are the recommendations on the WWRF and the future wastewater
rates based on different population growth scenarios. In order to provide a
comprehensive WWRF recommendation for the Commission, some initial work will
need to be completed.
This work includes a review
and/or modification to several growth scenarios and modifications to the
wastewater rate model. This process could take three or four months to complete.
This result will only provide what impact the WWRF has on rates not the future
rates needed to support the CIP and RRP in addition to the WWRF. In order to
provide future rates, the master plan would need to be completed as outlined
above.
The results of the master
planning effort will be a plan that maintains the existing wastewater
infrastructure, plans for future growth and provides the rates necessary to
fund the plan. It might be advisable to conduct a study session with the
Commission to clearly define the objectives and underlying growth assumptions
that will form the basis of the plan. This would include the la
The cost of the project as
outlined in the RFP is estimated to be $300,000 to $350,000.
Project Status
On
March 11, 2008, the City Commission authorized staff to advertise a Request for
Proposals for professional engineering services to prepare a wastewater
facilities master plan including a
review of the scope and timing of the Wakarusa Water Reclamation Facility.
On April 25, 2008 in response to the Request for Proposals,
staff received proposals from four (4) groups interested in the project.
Proposals were received from George Butler Associates, Inc., Burns &
McDonnell/BG Consultants, Carollo and Black & Veatch.
A review committee of staff
members from the Departments of City Manager’s Office, Public Works and
Utilities evaluated the four proposals. As indicated in the RFP, the following
criteria were used to rate the responses:
Project
organization & approach 30%
Firm
experience with similar projects 30%
Schedule
to complete the project 30%
Value
added concepts proposed by consultant 10%
Staff consistently ranked
Burns & McDonnell/BG and Black & Veatch as the two highest qualified
respondents for the project. Based on the rankings, the Burns & McDonnell/BG
team is recommended to begin contract negotiations.
Project Funding
The project could be
funded with a budget authority transfer from the Non-bonded Construction
account to the Operations and Maintenance line item for Professional Services.
The current balance of the Non-bonded Construction account is $7.78 million.
Recommendation
Authorize
staff to begin contract negotiations with Burns & McDonnel/BG for an update
on the Wastewater Facilities Master Plan
