Re High Service Pumping Station Improvements
For Service To The
Northwest Denton Area
Dear Mr Nelson
We herewith offer you our planning and engineering services for the design and
development of a high service pumping facility to serve the growth in the
higher elevations of the northwest Denton area
The proposed facilities will generally include two vertical turbine high
service pumps each with a capacity up to approximately 750 G P M Each pump
will be operated with a variable speed controller which will provide a
variable flow at a constant pressure The project will include the
utilization of some existing water distribution mains and installation of new
controls, piping, metering, electrical, gates valves, check valves, fittings,
gearr
and hr related motor t control center, recordersr,g and to her considered
enclosure of
The projected construction cost for the proposed improvements is $225,000 00
This construction cost projection has been prepared for budget purposed only
and is not guaranteed as the exact amount which will be bid for furnishing and
installing the proposed improvements.
A Pre-Work Conference
We will meet with the City Staff to discuss the design criteria,
alignments, public relations with property owners, right-of-way
acquisition, work program and schedule, procedures of communication,
additional surveys, preparation of preliminary layouts, assignment of
personnel, and any other matters that may have a direct or indirect effect
upon the completion and conferences will be scheduled throughout the~progress tof the workd for review
