Many of the irrigation canals would be available to convey additional stormwater reducing the amount of stormwater infrastructure that the cities would need. This benefit is approximately $46 million in today’s dollars.

Logan City would see a reduced amount of infiltration that enters the sewer collection system. Sewer treatment plant operation and maintenance costs would be reduced because of reduced flow. $0.9 million is the calculated sanitary yearly sewer benefit.

The water being used to water lawns in the Crockett service area would not need to be pumped from culinary wells which will create power savings. $130,000 would be saved annually now by reducing pumping of culinary water if a PI system were installed and $359,000 would be saved annually at build out.

Valuable water will be conserved by piping the irrigation system. The value of the conserved water over a 50-year period is $63.75 million in today’s dollars.

Pressurizing the irrigation system may allow more space for trails to be constructed along canal rights of way.

Water rights will be protected from transfer to the Wasatch Front by utilizing surplus water saved through system efficiencies.

• Water usage can be verified through meters used on the PI system.
• Water used in PI systems can be accounted for in a community 40-year water rights plan. This provides long-term protection to water rights.
• Water that has not been used to irrigate land converted to residential use would immediately be put back to beneficial use.

Enclosed irrigation systems are safer than traditional open systems.

Grant opportunities for secondary water systems are more available than for culinary water systems.

There will be more flexibility of irrigation times for PI systems. There is also flexibility on how water is applied to the land. This allows users more control over when and how they irrigate.

Currently the canals require a base flow (carrier water) to deliver any water for irrigation use. Pressurized irrigation does not require carrier water to irrigate. This allows all the water to be used for irrigation or other beneficial uses and will allow water to stay in First Dam which will provide for less restrictions and more available water when demand is high.

Land with pressurized irrigation for agricultural and landscape irrigation purposes is of higher property value than land that uses gravity irrigation or culinary water for irrigation.

The Crockett diversion is aging and will need to be replaced if the Do Nothing Alternative is selected. Construction of a complete PI system will remove the need for a new Crockett diversion structure.
