Description
This course is designed to provide landscape architects with continuing education credits for occupational license renewal. Water conservation is not a concern of a few isolated areas, as the supply of fresh, clean water is a scarcity for millions of people on this planet.

The conservation of fresh water supplies has become a local, national and global issue. Conserved water is a “water source.” By redistributing existing water supplies through conservation efforts, there are economic, environmental, and political advantages. The recovery, purification, and distribution of water consume large amounts of energy. Therefore, water conservation also conserves energy.

Drip irrigation, using low-volume irrigation products correctly, can conserve significant amounts of water. Estimates and studies range from 50% to 90% water savings. Drip irrigation may also be beneficial to safety, maintenance, and repair issues by keeping water off of sidewalks, streets, walls, and windows.

Learning Outcomes
* Be aware of the conservation aspects of drip irrigation
* Compare the advantages and limitations of low-volume irrigation.
* Make informed decisions based on the project, site conditions and intended use.
* Establish a procedure for designing a low-volume irrigation system.
* Determine an appropriate design approach based upon the planting scheme.
* Identify low-volume irrigation components.
* Be aware of the climate’s affect on evapotranspiration and application efficiency.
* Identify dense or sparse planting schemes.
* Determine the “base plant” in dense and sparse planting schemes.
* Calculate the crop coefficient and the factors that affect it.
* Determine the exact spacing between rows of in-line emitter tubing.
* Evaluate minimum watering depths, emitter spacing, and areas wetted by emitters.
* Determine the run time for low-volume irrigation hydro-zones.
* Understand the relationship of the type of soil to the maximum run time.
* Calculate the irrigation interval of the low-volume irrigation system.
* Calculate the minimum flow rate based upon the pre-determined run time.
* Determine the quantity and type of emitter based upon the pre-determined run time
and the water requirement of the “non-base” plant.
