                            Project Description and Request for Proposals

Jemez Pueblo Wastewater Treatment Upgrade

Project Description:
The goal of the project is to develop a feasibility study and design of a significant upgrade for wastewater
management for the Jemez Pueblo, New Mexico. This is a real need for the community, and already coordination
between ICAST, CH2M Hill, and CU is underway. All currently available documentation will be made available to
the project team. Currently the wastewater is discharged to 3 lined lagoons from which the water evaporates. Due to
the lack of designed discharge no permit or water quality monitoring has historically been required. However, as the
population of the Pueblo has continued to grow, evaporative processes are no longer keeping pace with wastewater
generation. In addition, the water is a valuable resource the could be used for agricultural irrigation rather than
simply lost. The community needs a short term solution to prevent the discharge of untreated wastewater in the
winter months (starting in October 2003) and a longer term solution for wastewater management as the community
grows. It is likely that the community WILL implement your solution, and as such your design will have input from
licensed engineers at CH2M Hill who would be responsible for final approval of all design document. Due to the
urgency and real need for this project, a larger than normal team will be assembled to satisfy the project
requirements.

Objectives
 Determine a short term solution that can be implemented in October, to avoid the discharge of untreated
    wastewater
 Evaluate options for wastewater management. These include (but are not limited to):
       continue use of non-discharging evaporative ponds by adding additional surface area
       various discharge options, such as to agricultural fields, groundwater, or surface water
       appropriate and sustainable methods to treat the wastewater to achieve water quality that is compatible
          with the end use (processes using solar or wind power are of specific interest)
 Design the upgrade to the wastewater management facilities. These should be sized to accommodate 20 years
    of community growth. Plans should be as specific as possible, with specific equipment compared and
    recommended.
 Estimate the cost of the treatment system. Determine what costs can likely be deferred by grants and those that
    will be charged to the community.
 Determine a plan by which the new facilities can be constructed while maintaining adequate wastewater
    handling.
 Produce an operations and maintenance manual that addresses start-up, monitoring for regulatory compliance,
    and routine maintenance

Constraints
 Minimize operator skills and time by simple, reliable processes. At present, no plant operator has been needed.
 Ensure that process is compatible with local climate conditions.
 Minimize both capital and operation/maintenance costs. The reservation has a small population with a fairly
   low average income.
 The facility must meet all applicable federal, state, local, and tribal regulations and standards.

                       iii. Various disinfection methods
       all options should include sustainable power sources such as solar and wind, as appropriate
