The Realities of Water Usage
Location Impacts Usage
only Some Precipitation Makes It to Water Sources
- Of the rain and snow that do fall each year, around 70% of it goes back up into the atmosphere through evaporation. A heavy rain or snowfall doesn’t replenish water as quickly as some may believe. If you get an inch of rain during a storm, only 3/10s an inch of that rainfall is going to return to the area’s bodies of water. You should also consider how much water accumulates in …
Deteriorating Infrastructure Is Another Problem
- Adding to the issues of public water systems is the deteriorating infrastructure the U.S. is experiencing. Roadways, bridges, and rail systems aren’t all that make up the infrastructure. The underground piping that brings water from a water treatment plant or water storage tanks to homes and businesses is also a big part of the problem. The EPA estimates that in the next 25 y…
We Need to Work Together
- Homeowners and businesses should do their part by reducing consumption by fixing leaks, updating older appliances that are water hogs, and collecting water in rain barrels for watering gardens and lawns. Limiting the time spent in a shower and proper maintenance of septic systems also helps. Water treatment plants must also do their part. Water tre...
