Bureau of Reclamation for the Design and Construction of the Expansion of the
Recycled Water Tertiary Treatment System; Authorizing the City Manager to
Execute All Necessary Application Documents; and Authorizing the Mayor to
Vote to Support the Inclusion of the Project in the North Bay Water Reuse
Authority Grant Application
RECOMMENDATION
It is recommended that the City Council adopt the attached Resolution authorizing the submittal
of a financial assistance application to the Bureau of Reclamation for the design and construction
of the expansion of the Recycled Water Tertiary Treatment System; authorizing the City
Manager to execute all necessary application documents; and authorizing the Mayor to vote to
support the inclusion of the project in the North Bay Water Reuse Authority grant application.
BACKGROUND
Following the adoption by the City of Petaluma of the Recycled Water Master Plan in 2004, the
General Plan in 2008, and the certification of the Recycled Water Environmental Impact Report
in 2008, the Public Works and Utilities Department staff and consultants have pursued studies,
engineering, and funding for the next phases of the recycled water expansion program. On
November 16, 2015, Council held a workshop on Recycled Water program plans.
The Recycled Water Master Plan and subsequent studies have projected recycled water demands
for urban and agriculture uses that exceed the production capacity of the Ellis Creek Water
Recycling Facility and the existing "purple pipe" distribution system. In order to take advantage
of reuse opportunities, reduce potable water demands, and expand the City's wastewater disposal
options, the recycled water expansion program includes increasing tertiary treatment capacity
and expanding the urban and agricultural "purple pipe" distribution system. The tertiary filtration
and ultraviolet (UV) disinfection system would increase from 4.68 to 6.8 million gallons per day
(mgd).
The City constructed one portion of the urban recycled water system expansion last year (to
serve Kaiser Medical Center and portions of the Oakmead Business Park) using a contribution
from Kaiser and Wastewater Enterprise Funds. Another portion of the urban system is in
construction (Sonoma Mountain pipeline) funded with a state Proposition 1 grant and
Wastewater Enterprise Funds.
To assist in funding the recycled water expansion, the City became a member of the North Bay
Water Reuse Authority (NBWRA) to pursue federal funding from the U.S. Bureau of
Reclamation (USBR) Title XVI program along with other regional funding opportunities. The
Title XVI program could provide up to 25% grant funding for construction and related costs. The
City has participated in NBWRA since 2013 and the City's recycled water system expansion
projects are included in Phase 2 of the NBWRA program. The City has contributed $13M to
NBWRA for a scoping study, a feasibility study, environmental review, and program fees.
DISCUSSION
USBR recently released a Funding Opportunity Announcement for $ l OM in grants for this
federal fiscal year. Additional funding opportunities are expected in future years. USBR funding
provides an ideal opportunity for the City to finance part of the expansion of the recycled water
facilities by leveraging local and state funds. USBR grants can be used to fund up to 25% of
eligible project costs, including construction allowances. At least 75% local cost share match
must be provided.
Funding limitations and program requirements will affect the financing and phasing of the
recycled water expansion program. USBR intends to fund 4 -8 projects this year, and NBWRA is
competing against 37 other projects for these funds. Projects funded in this funding cycle must
complete construction by September 30, 2019. In order to qualify for USBR funding, the
Environmental Impact Report/Environmental Impact Statement Record of Decision (ROD) must
be completed. The NBWRA Phase 2 ROD is expected to be completed in fall 2018, so this is the
first opportunity for the City to apply for USBR funds. No other NBWRA members are
submitting funding requests this year.
The highest priority project was identified as the expansion of the Tertiary Treatment System
consisting of the addition. of five filter cells in. the mirror image (i.e., same size and type) as the
currently existing filters and the installation of ultraviolet lights into the existing unused third
channel. The estimated construction cost is $5.4M. The estimated cost of this project, using
USBR calculations for overhead and other costs is $9M. The requested USBR grant would be
$2.25M (25% of total project costs).
The design of the tertiary treatment expansion is underway and is expected to be ready to bid in
mid -2018. If the City is not awarded the entire requested grant amount in this funding cycle, the
remainder can be requested in future cycles. (For example, Napa Sanitation District's full project
in NBWRA Phase.1 was funded over four cycles). Future USBR Title XVI funding could
include any remaining unfinished elements of the urban distribution system, and the agricultural
distribution system.
2
In order to expedite the Proposition 1 funding process, Council is asked to authorize the City
Manager to sign all required application materials.
FINANCIAL IMPACTS
The current action authorizes submittal of the application and supporting documents. If
successful, the grant amount will be up to $2,250,000 in support to the current CIP project,
C66401416. The current CIP anticipated USBR grants of $4,138,000 for the tertiary treatment
and recycled water pipeline expansions through FY 21/22 with the project funding match paid
from Wastewater Enterprise Funds. The proposed action is consistent with the current CIP
budget.
The 5 -year financial forecast model was used to evaluate the impact of the CIP project on future
year fund balance reserves. Based on recent savings with other water recycling facility CIP
projects and projected revenues, the wastewater enterprise fund balance would dip to a projected
low of $12.5 million in FY 20/21 before stabilizing in the $17.5 million range for the next
several years. These are considered healthy fund balance levels for a similarly sized utility.
