AGENDA STATEMENT
Item No. C.i.
For Meeting of: October 20, 2020
ITEM TITLE: Water Treatment Plant Receives Gold Certificate of Achievement
for 10 years of Outstanding Performance producing drinking water
SUBMITTED BY: Scott Schafer, Director of Public Works
David Brown,Assistant Director of Public Works, 509-575-6204
Jeff Bond, Water Treatment Plant Supervisor
SUMMARY EXPLANATION:
The Office of Drinking Water began the Treatment Optimization Program (TOP) in 2001 in an
effort to recognize and improve performance at rapid rate filtration surface water treatment
facilities like the one operated by the City of Yakima. The objective of the voluntary program is to
maximize public health protection provided by surface water filtration plants. The City joined TOP in
2006.
This is the third award the Water Division has received. The first was a Bronze Award in 2013,
followed by the Silver Award in 2015. For the calendar years 2010-2019, the City of Yakima's
Water Treatment Plant produced finished water turbidity of 0.10 NTU or less, at least 95 percent
of the time; meeting TOP's turbidity goal and other stringent criteria related to public health
protection and the accomplishment of obtaining the Gold Award. Achieving consistently high
drinking water quality like this is the mark of highly dedicated and skilled Water Treatment Plant
operators.
Beginning in 2001, in an effort to keep our customers informed about Yakima water, we have
provided the annual Water Quality Report in both English and Spanish. This report is also a state
mandate. The 2019 report is included and can also be viewed at
https://www.yakimawa.gov/services/water-irrigation/.

Dear DAVID BROWN:
I would like to recognize the staff at the City of Yakima Water Division's drinking water treatment plant
for their contribution to outstanding performance and treatment optimization.
The Office of Drinking Water began the Treatment Optimization Program (TOP) in 2001 in an effort to
recognize and improve performance of rapid rate filtration surface water treatment facilities. The objective of
this voluntary program is to maximize public health protection provided by surface water filtration plants
like yours,
Over the past almost two decades,participants in the program have committed themselves to attaining
treatment optimization goals for particle removal and disinfection that are more stringent than existing
regulatory requirements. Because turbidity is a readily measured indicator of treatment performance for
conventional and direct filtration plants, TOP tracks finished water turbidity data for all of these plants in
Washington.
For the calendar years 2010-2019, your plant's finished water turbidity was 0.10 NTU or less, at least 95
percent of the time, meeting Tt)13's turbidity goal. Achieving consistently high drinking water quality like
this is the mark of a highly dedicated and skilled water department staff.
To receive this award, a plant must also meet other stringent criteria related to public health protection. Your
plant is one of eight to receive an award this year. Please accept this Gold Certificate of Achievement
(enclosed) and my congratulations for I 0 years of outstanding performance.
Sincerely, 1
Mike Means
