For the folks at Green Squared, we have been working on a couple of retrofit projects where WATER retrofits have provided substantial paybacks under 18 months.

Plus, several cities including Houston and Colorado Springs, are in the process of raising water rates as much as 50%, so those paybacks will likely shorten even further.

GreenerBuildings.com ran a great article on water last month that is worth the read.

To highlight some great points:

1. Fix all leaks and install water-saving flow restrictor aerators in faucets and showers.
2. Retrofit existing toilets with flushkits for greater efficiency or for dual-flush capability.
3. Upgrade irrigation controls.
4. Retrofit irrigation system with controls that incorporate smart technology on a plug-and-play basis.
5. Replace toilets with higher efficiency fixtures. Consider dual-flush models.
6. Install low-flow or waterless urinals.
7. Install low-flow, sensor-activated faucets in restrooms.
8. Outdoors, change the way you water with a drip irrigation system
9. Change what you water.

Great stuff.
