Contract No.: 16 Project No. : 150338 Date: April 16, 2018
Client: Kittitas County
Project Name: Consumptive Use Pilot Study
Description of Work Cost
Aspect Consulting, LLC (Aspect) understands that Kittitas County and
Patrick Deneen are partnering on a pilot study to quantitatively determine
the percent of consumptive use associated with indoor-only domestic use.
The results of the study will be used to determine the efficacy of alternative
mitigation strategies in subbasins currently without suitable mitigation
options (e.g., yellow and red zones). We understand that the parties have
requested Aspect provide oversight during design, implementation, and
reporting of the study results.
Based on this understanding, Aspect will complete the following tasks:
Task 1 - Preparation and Presentation to WTWG. Under this task,
Aspect will prepare all materials and present the basis of the pilot-study to
the Yakima Basin Water Transfer Working Group (WTWG). We will use
the existing materials as the basis for the presentation.
We understand the group would like to present at the May 7th WTWG
meeting, requiring submittal for draft materials by May 30th. We do not
expect an official endorsement from the group, but rather a facilitated
discussion to get feedback and general agreement on the pilot study
concept and methodology.
Task 2 – Pilot Study Methodology Design. Using the existing narrative
and feedback from the WTWG, Aspect will develop a basis for design.
The design will not only include the physical requirements of the pilot
study (meters, membrane bioreactor, cisterns), but also the approach,
including necessary measures for quality assurance and control.
We anticipate facilitating one meeting with key basin stakeholders
(Yakama Nation, WDFW, Ecology) to review and discuss design details,
including proper site-specific siting of the drain fields and supplemental
cisterns. Proper siting will be important to ensure all potential tributary (i.e.
Fowler Creek) impacts are mitigated.
These services will be
provided on a Time and
Materials basis.
Task 1: $2,000
Task 2: $3,500

Project No. 150338

The final design will include a technical memorandum outlining the
problem statement and investigatory methodology, with details describing
the construction details, vendor specifications, quality control measures,
and input from basin stakeholders.
Task 3 – Implementation and Monitoring. Under this task Aspect will:
• Conduct a site inspection to document construction of a
representative home and septic, including confirmation of meter
installation (per manufacturer specification) and locations.
• Conduct site measurements in accordance with design (Task 2).
• Take construction photos and GPS measurements to correlate with
parcel information.
We anticipate the pilot study to be at least 16 to 24 months in duration. We
assume the County will provide the raw telemetry water meter data on a
monthly basis. Aspect will evaluate this data (assume two hours per month)
and provide an email status update, including an estimate of consumptive
use. The update will be suitable for distribution to basin stakeholders.
Task 4 – Preparation of a Technical Report. Under this task Aspect will
compile and produce a technical report documenting design, construction,
and implementation of the consumptive use pilot study. The report will
conclude with an estimate of consumptive use and additional observation
and/or recommendations, as needed. To promote cost efficiency,
documentation produced under Task 2 will be directly incorporated into the
report. A draft report will be provided for early group review. In addition,
we have budgeted for one meeting with the group to discuss findings of the
report. Following resolution of any comments, a final report will be
produced.
Task 3: $7,500
Task 4: $3,500
