Irrigation Reuse

Potential benefits of non-potable reuse include:
. Improves M&I reliability.
. Maximizes successive uses of water.
. Maximizes beneficial use of water.
. May not require new diversion structures.
. Lesser environmental impacts than a new water
supply project.

. Does not use higher quality drinking water
for irrigation.

Potential issues and concerns include:

. Can be very expensive.

. Must have consumable effluent to reuse or
identified return flows.

. Wastewater treatment plant needs to be
near irrigation demands.

. Must have storage to regulate year round
effluent flows and meet demands during
irrigation season.

. As M&I users develop or expand the reuse
of existing reusable return flows via water
rights exchanges less water may be
available to downstream users.

. Previously unused reusable effluent historically
resulted in reduced or more junior river calls
controlling the river.

. River calls may become more senior, impacting all
users.

. Public acceptance of the reuse of effluent for
landscape irrigation must be achieved.
