D.3.3 Pipelines

The cost of pipelines is estimated based on experience in water

I

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.

D.3.4 River Diversion Structures

River diversion structures were included for parcels over 30 acres.

I

The diversion structure would be constructed across the river to form

I

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

I

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

damage.

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

The

I

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

I

River.

I

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

I

would probably have a simple temporary diversion which could be

I

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
