- 635 Million Gallons are used to keep freeway shoulders green
- 75% of roadside sprinklers do NOT have smart irrigation systems
- Commercial customers pay $0.003 (less than half of a cent) per gallon of water
- There is no financial incentive for commercial customers to conserve
- Residential customers pay more for water as they use more (incentive to conserve)
