PLAN OF DEVELOPMENT

I

Physical plan

I

The planned water-distribution system is proposed to serve the more

densely populated areas of rural Morgan County--generally the irrigated

portions of the county. The proposed layout shown in Figure 2 was

established to provide service to most areas in which there now exist at

least four households per square mile. The proposed system will not serve

the cities and town of Fort Morgan, Brush or Wiggins, which have established

municipal supplies. The system shown in Figure 2 would serve those small

communities that do not have central supplies such as Orchard, Goodrich,

Weldona, Snyder and Hillrose. The estimated 1975 population of the proposed

service area is 7000-7200. (See footnote 2, page 2, RE: Narrows Reservoir.)

Other physical aspects of the plan include four wells and pumping

plants located in Section 5 and 8, T3N, R61\v. A 15-inch transmission line

is proposed to conduct water from the well field to the western edge of the

district (about 5-1/2 miles). Three storage reservoirs are planned to

provide supply regulation as well as supplies during breakdowns or other

emergencies. It is expected that the water will be chlorinated prior to its

introduction into the distribution system, but that no other treatment will

be required.

Design

II
I

Design criteria and standards are summarized below.

I

Pipeline sizing. Pipeline sizes are selected to provide adequate

capacity for peak flow demands. Peak flow demand for the preliminary design

was assumed to be 1000 gallons per day per tap. Final design refinements

will take into consideration variations in expected uses, particularly

identifying large users such as feedlots. Minimum pipe size in the

distribution system is 2 inches.

I

Pressures. The design criteria for minimum and maximum pressures are
25 and 90 psi, respectively. The system is analyzed by computer using the
Hardy-Cross method to insure pressures within this range. Pressure reducing
valves are specified in areas where elevation differences cause excessive
pressure. A booster pumping station is indicated to be necessary to serve
an area north of Fort Morgan.
