Irrigation Water Conveyance Pipeline Design

My Desire: What I wanted to accomplish

Design, specify, and draw irrigation delivery pipelines that are served by a main supply pipeline for a Special Agricultural Conservation Program (ACP) Irrigation Water Conveyance Pipeline Project.  This USDA Natural Resources Conservation Service design project was a service to lateral landowners and the Greeley Field Office.

Description of the result

Designed and specified approximately $65,760 worth of delivery pipelines, water control structures, and appurtenances.  Had primary responsibility in surveying the site and developing design drawings.  The area engineer designed the main supply pipeline (main 27-inch pipeline to convey a maximum 24.0 cubic feet per second (cfs) flow) that was to service the delivery pipelines.  Designs were completed and bids were received in the spring of 1992.  The total engineers cost estimate was $366,600.

Any measure or quantities to prove my accomplishment

My lateral design contributions were as follows:

 

Items

Total Quantity

Unit

Cost

 

 

8” to 21” diameter polyvinyl chloride (PVC), SDR 51 pipes

1,437

Linear foot

$22,060

 

 

8” to 18” diameter gates

5

Each

4,000

 

 

2” to 3” diameter air release valves

3

Each

950

 

 

8” to 21” diameter slide gates

13

Each

9,000

 

 

Total pipes and appurtenances estimate =

$36,010

 

 

Reinforced concrete water control structures

» 70

Cubic yard

» 29,750

 

 

Approximate total estimate

$65,760

 

 

The water control structures reinforced concrete volumes were based on a third of the total reinforced concrete volume.  This is a judgment since plans could not be consulted for the development of this document.
