Memorandum
Deschutes County Board of Date: August 8, 2008
Commissioners
From: Dick Nichols
Project Name: Sunriver
Subject: Grant for Feasibility Study for Project No.: 1053-102
Extending Sewers from
Sunriver and Reusing Treated
Effluent
Sunriver Environmental LLC is currently in the process of upgrading its sewerage facility to meet
DEQ -mandated treatment requirements required by the existing Sunriver wastewater disposal
permit. This event presents a "once in a lifetime opportunity" to economically expand the
treatment plant and reuse facilities to provide service to areas south of Sunriver that are currently
served by inadequate septic systems. The DEQ is very interested in exploring this possibility and
has granted a time extension to the Sunriver sewerage treatment plant upgrade process to allow
interested parties to explore the feasibility and possibility of taking advantage of this window of
opportunity.
There would seem to be local interest for sewer service, but there are also questions about the
feasibility and cost of providing this service. These issues could be defined and answered
through a feasibility study.
Currently, the Oregon Water Resources Department has grant money's available to conduct
feasibility studies on effluent reuse. Applications for the grant to conduct the feasibility study are
due September 2, 2008. The grant requires a 50% match. The application must demonstrate that
the match money is secured.
The feasibility study would analyze the following issues:
1. Potential areas south of Sunriver that could be cost effectively served through an
expansion of the Sunriver sewerage facilities.
2. Estimated costs of extending sewers to those areas south of Sunriver.

3. Estimated costs of locating and expanding Sunriver sewage treatment and reuse facilities
to accommodate expanded service area outside of Sunriver.
4. How current mandated upgrade costs and potential system expansion costs would be
allocated between current users and potential, new users outside Sunriver.
5. Options for creating a public jurisdiction that would collect revenue, obtain grants, and
administer to the construction, operation and maintenance of the sewage collection
system and which would contract with Sunriver for treating and reusing treated effluent.
6. Changes to land use ordinances necessary to allow for extension of sewers.
7. Alternatives for financing the construction, operation and maintenance of the sewerage
facilities.
A very cursory, ball park figure for the feasibility study is estimated to be $150,000. The match,
then, would be $75,000. This figure would be refined when the application is prepared.
The purpose of bringing this matter to the Deschutes County Board of Commissioners is to
request:
a. Deschutes County to provide the 50% match.
b. Deschutes County staff to help Sunriver prepare the application for the grant.
