0.3.3 Pipelines
The cost of pipelines is estimated based on experience in water
transmission pipeline work. The least cost type of pipe material
for the various diameters is reflected in the estimate. Pipeline
costs have been compared with pipeline cost estimates from the united
States Bureau of Reclamation (USBR) Dolores Project as well as the
Animas-La Plata Definite Plan Report. Installed estimated pipeline
costs are shown in Table 0.1.

0.3.4 River Diversion Structures

River diversion structures were included for parcels over 30 acres.

The diversion structure would be constructed across the river to form

a pool of water with sufficient depth for the pump to draw from. A

weir type diversion structure consists of a 4 foot high wall with a

footing and riprap on each side for stability and protection from ice

damage. The estimated cost of the structure is $210 per foot. The

diversion structures were estimated to be 50 feet long for the La

Plata River.

It may not be practical to build a massive diversion to serve a small

parcel. A farmer farming a small parcel with low flow requirements

would probabl y ha ve a si mple temporary di ver s ion wh ich could be
nothing more than a berm graded across the river with a backhoe or
dozer to form a shallow pool for his pump to take suction from if
flows in the stream are low. If stream flows were too large to allow
installation of a temporary diversion, a low flow could most likely
be pumped without a diversion.
