Task 2 - Develop Options and Select Criteria
The purpose of this task is to determine which options will be evaluated in detail
and to define the criteria which will be used to evaluate them. Necessary
background information will be collected including a description of the flows and
loads and regulatory framework. Available options will be described and
appropriate options selected for detailed evaluation. This task will include the
following subtasks:
2.1
Project Management. Project management will consist of reviews by
managerial level engineers, maintenance of scheduling and budget
control, correspondence with Owner, and supervision of project staff.
Project management also covers the procurement, supervision, and
coordination of subcontractors providing specialized or supplemental
engineering services and project closeout.
2.2 Develop available options. This will include the following subtasks:
Describe study area characteristics. The sewerage study area
will be defined and the physical and socioeconomic
environment will be described. The description of the physical
environment will include topography, geology, soils, climate,
and water resources. The socioeconomic environment will
include population and land use based on the city's adopted
comprehensive land use plan. The study area description will
include information on potential irrigation areas surrounding
Ashland.
Project wastewater flows and loads. Existing wastewater data
will be collated. Future flows and loads will be estimated using
published population projections. Historical flow records will be

used to estimate infiltration and inflow (I/I). A more detailed I/I
evaluation will be conducted as part of in-field flow investigation
to be conducted under a later task.
Co
Describe existing wastewater system. The description will
include a history and status of the existing collection system
and a detailed assessment of the existing wastewater treatment
plant including expected life and performance. Describe the
existing sludge handling practices, sludge treatment efficiencies,
current disposal sites and available equipment.
do
Summarize waste load allocations and regulatory requirements.
The regulatory framework will include a description of the status
of new wastewater effluent reuse regulations currently under
revision by the DEQ.
Define wastewater treatment and reuse options. These options
will include but not be limited to those options outlined in the
Draft Program Plan plus wetlands opportunities. General
design criteria and process schematics will be prepared. The
options will be developed in sufficient detail to identify features
or components critical to the screening criteria developed in the
following subtask.
Develop and apply screening criteria. These criteria will be selected
with Owner participation to be used in a pass/fail screening of
possible options. The screening criteria will include the technical,
regulatory, institutional and legal concerns included in the Draft
Program Plan. Capital and operation and maintenance costs will not
be provided for each option at this stage. Costs from established
cost curves which show order-of-magnitude estimates may be used
for options which cannot be adequately evaluated by application of
the other screening criteria. A maximum of four options which pass
the application of the criteria will be retained for detailed evaluation
and comparison.
Conduct a meeting with City staff in the Brown and Caldwell Eugene
office to present preliminary results of the screening procedure and
solicit input.
Select and describe evaluation criteria. These criteria will be used for
detailed comparison of the most promising alternatives.
Prepare draft Phase 1 facilities plan chapters. Draft chapters will be
prepared on study area characteristics, existing wastewater system,
wastewater flows and loads, regulatory requirements, and selection
of alternatives. Other facilities plan chapters including the
Exhibit B
October 3, 1990
Page 4 of 7
introduction, summary and recommendations, evaluation of
alternatives, and description of the recommended plan will be
prepared in subsequent tasks of the project.
2.7
Present draft facilities plan chapters to city staff, city council, and
DEQ. Obtain their comments and incorporate into the draft
chapters.
Task 3 - Collect Field Data and Perform Process Testing
This task of the work is to collect detailed environmental and wastewater process
data which is currently unavailable but necessary for detailed sizing of the
treatment processes. The full extent of this testing will be determined after
completion of the preceding task where the availability of existing data is
determined and the alternatives are selected for evaluation. The following
subtasks can be defined at this time:
3.1
Assist with the installation of Bear Creek flow monitor. Sizing of
alternatives will depend on accurate flow data for Bear Creek at
Ashland. This task assumes that the gaging station will be designed
by the United States Geological Survey (USGS) and installed by
Owner and USGS. This task includes the following subtasks:
Select flow monitoring site and method. The Engineer will work
with the Owner and the USGS to select the monitoring site and
method. Monitoring instrumentation will be recommended
which in the future can be used to control wastewater treatment
plant discharge.
bo
Perform on-going preliminary analysis as flow data is generated
to verify data is reasonable and will be useable at end of the
monitoring period.
Co
Collect and collate flow data. At the end of one year, collect
flow data from Owner and compare flow data at Ashland with
weather data, flow data at Medford and irrigation flows to
estimate statistical variation of flows in Bear Creek at Ashland.
3.2
Infiltration and inflow investigation. Evaluate extent of current I/I
problem using existing data. Use existing data to determine if I/I is
"excessive" as defined by the Environmental Protection Agency
(EPA). Meet with the Owner and DEQ to define the scope of any
required I/I field work.
Exhibit B

3.3
Perform desk top analysis using existing data to provide
recommendations regarding specific in-stream studies. Options for
in-stream study include, but are not limited to, those included in the
Draft Program Plan.
Task 4 - Develop and Evaluation of Alternatives
In this work task, alternatives which remain following the screening in Task 3 are
developed and evaluated in detail. Treatment of the liquid portion of the sewage
flow is considered separately from the solids stream (sludge) for each
combination of alternatives. Following the evaluation of alternatives, at least two
alternatives will be identified for final selection in the next task.
4.1
Alternative Development. The alternatives remaining following the
screening process are described in detail. Design data will be
determined, preliminary layouts and facility sizes provided.
Alternative sites available for the construction of treatment and
disposal facilities will be identified. Elements common to a number
of alternatives will be identified.
4.2
Liquid Stream Evaluation. Using the criteria defined in task 2.3, this
task will evaluate treatment alternatives for the liquid portion of the
sewage flows. Capital and O&M costs will be provided for
comparison.
It is recognized that the required level of treatment for the alternatives
discharging to Bear Creek cannot be identified until summer flows
are estimated in 1991. To be able to proceed with the analysis, the
Bear Creek discharge alternatives will be evaluated assuming two
summer 7Q10 flow levels - a Iow flow and a high flow assumption.
Sizing of treatment facilities will be based upon the treatment levels
required at these two flows.
4.3
Solids Stream Treatment. Solids treatment for the alternatives
identified in Task 4.3 will be developed and evaluated in the following
subtasks:
Provide projections of the biological and chemical sludge
quantities expected from the screened treatment alternatives.
For alternatives with disposal to Bear Creek, two levels of
sludge production will be estimated assuming two levels of
treatment.
Evaluate sludge thickening, stabilization, dewatering and
storage options. Design data will be determined, preliminary
layouts and facility sizes provided. Specific sites available for
Exhibit B

Page 6 of 7
the construction of sludge treatment and storage facilities will
be evaluated. Capital and O&M costs will be provided for
comparison.
Evaluate future sludge utilization/disposal options including
municipal and agricultural land application.
4.4
Summary of Viable Alternatives. Results of the development and
evaluation of alternatives will be summarized. It is anticipated that
two alternatives will remain to be further refined, if necessary, in
Phase 2, following the completion of summer flow monitoring. One of
these two alternatives will then be selected as the recommended
alternative.
A meeting with City staff may be appropriate at this point to discuss
the evaluation process. If requested, such a meeting will be
conducted as an extra scope item.
4.5
Prepare draft Phase 1 facility plan chapter on Alternative
Development and Evaluation. Other Phase 2 facility plan chapters
including the introduction, summary and recommendations,
environmental assessment and description of the recommended plan
will be prepared in subsequent phases of the project.
4.6
Present draft facility plan chapter on Alternative Development and
Evaluation to city staff, city council, and DEQ. Obtain their
comments and incorporate into the draft chapter at the direction of
the Owner.
