A set of four different scenarios for irrigating the alfalfa field at the Acoma Waste Water Treatment Facility (WWTF) was presented to RMCI and IHS. Scenarios development is a useful planning and decision-making tool.  The posts that follow this one will demonstrate some of the differences in the cuts and fills and total earthwork as required by each option.

Each option has three associated maps :

i. a waterflow-bench map,

ii. a cut-fill map, and

iii.a dimensioned materials drawing

and tables to summarize key information.

Each option has its own advantages and disadvantages like options that use less pipe and fewer valves but require more earthwork.

The below table outlines the Materials Requirements for each Irrigation Options.
