RE: Town of Windsor, Colorado
Site Application
Pump Station No. 3, (Windsor Eastside Pump Station)
Respected Officials:
Enclosed are Applications for Site Approval for the lift station proposed for construction on the
cast side of Windsor, Colorado. The pump station will allow the Town of Windsor to provide
sewer service in a growth area on the east side of town which has been limited due to the shallow
sewers in their existing sanitary system. We respectfully request that you review, comment, and
recommend approval of this Site Application.
The proposed lift station is a Smith & Loveless recessed, wctwell mounted station. The station
will be equipped with an alarm system to notify the Town of a station failure. A stand-by, gas-
powered backup generator is proposed in case of a power failure. This stand-by generator will be
equipped with an automatic transfer switch.
Sewage will be treated by the Town of Windsor at its sewage lagoon system presently in operation
and operated by the Town of Windsor. The projected additional sewage will not impact the
capacity of their existing sewage treatment plant.
The Engineering Co. and the Town of Windsor would like to thank you in advance for an
expedited review and subsequent approval. If you have any questions during the review of this Site
Application, please do not hesitate to contact our office.
Respectfully yours,

Project Description
Windsor Colorado is a small community with a population of approximately 6,000 people. Their
sewer collection and treatment needs are addressed by the Town. Their sewage treatment facility
consists of lagoons and is located southeast of the Town limits. The Town of Windsor is a rapidly-
growing community with sewer service problems which exist on the east side of Town. Due to the
shallow depth of collection sewers, the east and north parts of Windsor have trouble with gravity
flowing to the lagoon. In the early days, the Town did not consider growth on the east side in the
master planning for sewers. Due to projected interest in the growth of this region, the Windsor
Eastside Interceptor Sewer and Lift Station was formulated to provide a means to provide sewer
service to the property east of State Highway 257.
The Windsor Eastside Interceptor Sewer and Lift Station consists of a sanitary sewer collection
and transmission system, including a lift station,to service the property as outlined on Appendix A.
The projected service area consists of a proposed residential development (Garden East
Subdivision), a planned industrial site (Windsor Industrial Park), and future properties currently
unplanned but zoned residential and industrial. We have, in our planning of the interceptor sewer
and pump station, allowed for future sewerlines to be built to service these unplanned growth
areas.
Design of Sewerlines
Existing and Proposed Sewerlines
Appendix A contains a map of the area illustrating the existing and proposed sewerlines and how
the lift station ties the proposed system into the existing gravity sewer. The sewerlines, force
mains, and lift station that are a part of this work are highlighted. We have also shown on this
Appendix the lines which could be built to provide sewer service to areas of future development
within the service area. It was insured that the sewer we are designing would be deep enough and
that manholes would be aligned in order to facilitate the connection of future sewerlines as
proposed in the overall sewer master plan acknowledged by the Town.
Design Criteria
The design of the Windsor Eastside Interceptor Sewer is in accordance with the Town of Windsor
Sewer Design Criteria adopted October 1, 1987. The minimum public sewerline diameter is eight
inches (8"). The minimum depth of the sanitary sewer is maintained at three feet (3') to protect
against freezing. The sewerlines proposed for residential areas have been designed such that there
is adequate depth to allow for basement construction. As basements generally do not accompany
industrial sites, the sewer was not specifically designed to allow for basement construction.
However, due to the depth of the sewer in the industrial areas, basements could be facilitated. The
minimum slopes for all sewers were designed so as to insure adequate cleansing velocities of 2
ft../sec. A uniform grade and straight alignment has been maintained between manholes.
Manholes have been spaced with a maximum distance of 400 feet to insure accessibility for
maintenance. A drop of 0.1 foot through manholes without deflection and 0.2 foot of drop through
manholes with a deflection in alignment have been used to insure proper flow through manholes.
Manholes were placed at ends of lines, changes in grade, size, and alignment throughout the project
3
941132
as a general rile of design. The flow channel of each manhole invert is specified to conform to the
slope and shape of incoming sewers:
Design of Lift Station
Location of Lift Station
The location of Lift Station No. 3 was selected to best maximize the potential service area. The lift
station was located to facilitate using the existing gravity sewer as well as allow for the continued
operation of an existing six-inch (6") force main servicing the Metal Container Corporation plant.
We are placing a new manhole so that both the proposed force main from Lift Station No. 3 and
the existing force main from Metal Container Corporation will empty into it and continue by
gravity to the existing sewer system. We have secured an easement from the property owner to
place the station as well as build the interceptor sewer. We have made provisions by means of a
sewer stub out of the wetwell of our proposed lift station to the south for future use by the property
to the east of the station. It is highly conceivable that, in the near future, the property to the east of
the proposed pump station will develop and would require a tie into this station. We have also
made provisions to eliminate the force main from Metal Container Corporation by a joint
construction of a gravity sewer to service the property to the east of the station by dumping into
this future gravity sewer. The location of this proposed lift station is such that it is not within any
floodplain or natural hazard area.
Immediate and Future Design Flows
Initially,the Windsor Eastside Interceptor Sewer will service only the businesses in existence at the
time of construction. This includes the newly-constructed Universal Forest Products component
yard. This business currently employs 35 people in a light industrial capacity with a projected
growth to a maximum of 75 employees. Sewage projections include only that generated from the
normal daily use of toilets, drinking fountains, and wash sinks. Garden East Subdivision is
currently under construction with a projected capacity of 58 single-family homes. We anticipate a
complete build-out within a year if current building trends continue in this area. Currently under
planning consideration is the Windsor Tech Business Center. This planned development is
projecting 12 lots for mixed, light industrial use similar to that of Universal Forest Products. This
summarizes the immediate foreseeable loading on the sewer and lift station. However, the sizing of
the sewerlines,force main, and pump station takes into account future growth to the north and east
of the project. This projected growth is consistent with the Town of Windsor master plan. The
Town of Windsor staff has been involved with the planning of this project by providing
information related to future growth and its impact on the sizing and placement of the sewer
system.
Wastewater flows consist of residential and light industrial mixes. Residential flows were
calculated using 100 gallons per capita per day(gpcpd)which includes infiltration allowances. We
also assumed each lot would contain one home with an average household count of 3.5 person per
house. Light industrial loading was projected by comparing the density of Universal Forest
Products per acre and projecting this density to future light industrial parcels. The same loading
per person was used for light industrial, as was used for residential, at 100 gpcpd. A peaking
factor of 4.0 was used to estimate peak wastewater flows. Using these guidelines, the following
calculations were made for average and peak, immediate and future sewage loading.

Total Dynamic Head
Total Dynamic Head is calculated as the sum of the static head, friction losses, and local
("minor") losses in the force main and the fittings. In order to figure the static head, we
prepared a preliminary design of the proposed sewer route and rechecked our results after
a final design was complete. We took into account the depth of sewer requirements for
each of the projected users of the sewer system. We then determined the projected depth
of the pump station would be deeper than pumps at this altitude (5,000 +/-) could lift. As
a rule of thumb, we use fifteen feet (15') as the maximum allowable suction head for
pumps at this altitude. As our preliminary design required a suction head of some twenty
feet (20'), we looked for an alternative to our design. The recessed, canister-type of lift
station became an option we could work with. Future build-out conditions warranted a
deeper wetwell which, in turn, enforced our need for a recessed, elevated wetwell. The
static head was then calculated as the difference between the lower wetwell water elevation
subtracted from the invert of the gravity manhole. Pipe friction losses are minimal using
plastic pipe and having the force main length equal to thirty feet(30'). Losses in the pump
station were also figured in determining the total dynamic head(TDH).
Force Main
Several factors were considered in the design of the force main. Because our length of
force is short,thirty feet(30'), friction losses are negligible. Therefore, we sized the force
main to match the diameter of the suction lines and pump diameter. We believe the force
main was sized to best suit our economic feasibility and pumping needs.
Pump Selection
The various design parameters and conditions of the pump station are as follows:
Pump Station No. 3 is required to lift approximately fifteen feet (15') [measured from the
low level elevation to the pump discharge elevation] with a pumping discharge flow of 200
gpm at high level and 150 gpm at the low level. We have selected a pump to perform best
at a speed of 875 rpms. We have selected a recessed, wetwell mounted, non-clog pump
station by Smith & Loveless. The pumps, valves, motors, and controls would be housed
in a weatherproof, ventilated steel enclosure mounted over a 6-foot diameter standard
manhole. A fiberglass lid provides access into the enclosure..
The Smith & Loveless pump Model No. 4B2B met both the immediate and the future
build-out conditions. The advantage is that, for the future build-out conditions, the pump
station will remain largely intact. Only the impellers will have to be exchanged. The
pump efficiency is in an acceptable range for our immediate pumping requirements.
Initially, it is at 65% for the high water condition and at 58% for the low level condition.
At our future projected condition (with a 10- 1/8-inch diameter impeller) our pump
efficiency is at 72.8 % for the high level condition and drops to 72% for our low level
condition. We have selected 2 - 3 horsepower motors for our use.. Reference Appendix
C for the specification of the packaged pump station and Appendix D for the Pump Station
and Electric drawings.

941132
The system-head curve was calculated using the total dynamic head of the pump station
site and design. The system-head curve represents the total dynamic head against which
the pumps will be required to operate. It consists of the static head plus the friction losses
in pipe and fittings plotted against the projected flow. The change in the slope of the
system-head curve is an indication of the head losses due to friction. The maximum
system-head curve corresponds to the highest wetwell level and the lowest system-head
curve corresponds to the lowest wetwell level. The manufacturer's pump curve is plotted
on top of the system-head curve, and their intersection represents the operating range of the
station. (Refer to Appendix E for calculations of the system-head curve calculations).
The system-head curve and pump characteristic curves for Pump Station No. 3 are
attached on the following page.
The net positive suction requirements were checked for the pump station. Smith &
Loveless recommends twenty feet (20') maximum suction head limitation for sea level
recommendation with a deduction of one foot per thousand feet of elevation above sea
level. With this recommendation, fifteen feet(15') of suction head is allowed for the pump
station. Pump Station No. 3 has a maximum suction head equal to 14.4 feet which is
below the maximum allowable as previously discussed. The suction lines were sized for
build-out flows and checked for use with initial flows. We have attached a flanged end
with a bell to protect against vortex action as the velocities were too high using a plain end
for the suction lines.
The wetwell levels were set to optimize the pump cycling and ensure that the sewage in the
wetwell will have a detention time no longer than 20 minutes with average sewage inflows.
This is necessary to avoid septic conditions. The sales representative for Smith &
Loveless, as well as ourselves, will work with the operator to set these levels based upon
the initial flows to the station which will be limited until more growth occurs.
Soil Investigations
Soils investigations were conducted by this office, and the results indicate that standard
construction procedures will be used in the construction of the pump stations. Reference
Appendix F for a complete listing of the soil boring locations and logs.
Floodplain Analysis
The pump station site selected for construction are outside the 100-year floodplain as
determined by using the Flood Insurance Rate Map (FIRM) published by the Federal
Emergency Management Agency(FEMA)published for Weld County.
Analysis of Alternatives
In analyzing the alternatives to provide sewer service to the east side of Windsor, we
searched to find a means by which we could construct a gravity sewer to the wastewater
lagoons. The inadequate depth of a line to the Town's existing sewers and the cost of a
new collector line to the plant proved to be overwhelming when considering a gravity
sewer. A lift station was then researched to provide a sewer large enough and deep
enough to provide service to the study area.
7
941132
Our final design included the construction of a sewer system to collect and transport sewer
to a lift station where sewer could be lifted to an existing sewer manhole. The final
location of this lift station was selected because it could provide a place where gravity
sewers could service the entire study area and was also located within a few feet of a
gravity sewer. We, therefore, addressed two issues with the selection of this site. The
existing Town of Windsor plant is capable of treating the projected sewer flow as
illustrated in their current master plan of the Town.
Administrative Arrangements
Appendix H contains a letter from the Town of Windsor regarding the legal and financial
arrangements for the construction of the project and its' long-term management.
Implementation Plan and Schedule
The project is currently under bid and will begin construction of the sewerlines this fall.
We will await your approval prior to the placement and installation of the lift station.
