SUBJECT
recommendation
Authorize funding in the amount of $487,000 for an engineering services agreement with HDR Engineering, Inc. for preliminary design of the proposed Wylie Complex Reclaim System Improvements project.
end
PURPOSE
The Engineer will evaluate the hydraulics of the WTP I and WTP II reclaim system , propose modifications , evaluate the capacity of WTP I and WTP II reclaim basins, and develop a matrix of options based on different operational conditions. A Preliminary Design Report will be provided incorporating the results of hydraulic evaluations, pipeline changes and additional reclaim volume options, system modifications, and recommendations.

BACKGROUND
Historically, reclaim return flows at all water treatment plants were returned to the treatment process as raw water enters each plant, downstream of chlorine dioxide addition and mixing boxes. These reclaim return flows contain constituents that affect water chemistry as they are mixed, and the eventual overall finished water quality.
In particular, WTP I reclaim can become overloaded during normal operating conditions, particul...
