Summary
Pump Station Design Point: 120 gpm @ 160 TDH
Total Available Water Rights:82 gpm
Water Supply
The property is serviced off of the McDonald Lateral (Headgate#417), located south of the site.The
development has an independent delivery.

The gravity irrigation water enters the development site in the southwest corner and continues
north, draining to a piped discharge in Bancroft Square Subdivision to the north.
Water Demand
The typical calculated demand within the Boise Project Board of Control is 0.33 inches of water per
day over the sum of the irrigable acreage.The approximate maximum irrigable area is 5.75 acres,
resulting in a constant max demand of approx 36.2 gpm.
Irrigable Area: 250349 sf = 5.747 acres

This number has been noted as a 'maximum' as it is the total acreage subtract the hardscape
acreage.The site will utilize a variety of other surface treatments such as artificial turf and rock
cobble in the landscape plan that will not be consumptive users of irrigation water and will lessen the
demand on the system.
Delivery to Pumping Plant
Irrigation water is diverted to the pump station's wet well in the screen box. Check boards restrict
flow bypass of the screen and allow water to flow to the wet well. When delivery water flow exceeds
pump station consumption the water can overflow the boards.
Screen Box
The concrete screen box contains a Clemons CW-400 screen.The screen requires 20 gpm to operate;
this demand has been added to that of the pump station.The screen is not a consumptive use of
water; it can be recycled back into the screen box.The screen is located in the screen box and feeds
directly to the pump station.
Wet Well
The concrete wet well will have a diameter of 48".The depth will be 14.0 feet from top of wet well
to top of floor(to be verified by pump supplier),with 12.0 feet of total design water depth. Manhole
steps will be provided for maintenance inside the wet well.
Pumps
A pump with a capacity of 120 gpm at 160 TDH has been designed for this pump station. Plans
show one (1) submersible turbine pump but a vertical turbine is acceptable if desired by
developer. A jockey pump will be provided if determined to be necessary by the pump supplier.
Hydraulic Analysis
The developer has elected to use a 'design-build' system provided by the landscapers for this
development so this civil engineer has not completed a hydraulic analysis of the entire pressure
system. The 4" discharge line from the pump station is sized appropriately to minimize head
loss and keep an appropriate velocity upon discharge. Using Q=vA gpm the velocity at the
outlet is 3.03 ft/s, well below the typical maximum velocity of 5 ft/s.
