One essential to keep tourists happy and healthy is fresh water, and most resorts rely on desalination to provide it.
For nearly 100 years the district has provided reliable water to farm and residential customers—through population growth, drought years, and changes in land use.
Transporting over 5 billion gallons of water each year, the district has hundreds of miles of pipeline and more than 30 remote sites.
A lot of control engineers do, especially in fields like water treatment, refrigeration, thermoforming, refining, food processing, and energy or building management.
There are a variety of temperature sensors on the market—ICTDs, thermocouples, RTDs, thermistors, infrared sensors. Accuracy, cost, wiring complexity, and environmental conditions are some of the factors that determine which one is best for your application.
Nothing like a cold shower to get you moving:
Most of us never give any thought to our hot water service pilot flame. But when it goes out...cold shower first thing in the morning, anyone?
The first time it happened, I simply re-lit the pilot and showered with cold water. After the third cold shower, I knew it was time to be a little more proactive!
Avoiding this kind of mess is especially good when your business includes storing and disposing of liquid waste from industry and manufacturing.
That's the business Plummer's Environmental Services is in.
Along with a variety of other services—including hydro excavating, manhole rehabilitation, and emergency spill response—the Michigan-based company collects liquid waste from Midwest industrial and municipal customers, stores it, and treats it.
Monitoring the water mains:
As mentioned in my blog last week, it was not until I monitored my water usage that I found out I was not monitoring ALL of my water usage.
My whole house water meter was just that, the whole house. It did not show any of the garden/lawn water use.
Let's talk about how we might get that data and what it could mean for conserving water in all aspects of our lives.
The biggest user of water in our house is not human:
A web browser is installed on most of the key devices we use every day. PCs, smart phones, tablets, even our TVs now have a modern web browser installed. I can even surf the web from my Android smart watch (a Moto360).
It makes sense then, does it not, to view everyday data on an interface that we use every day?
How much water flows through our house was the subject of last week's blog... It both surprised me and pleased me to find out that the biggest user of water in our house was not a human.
The U.S. Drought Monitor at the University of Nebraska-Lincoln currently categorizes more than 94% of the state's total area as in "severe drought" or worse, and notes that snowpack statewide (from which we get most of our water through the year) is at only 5% of normal.
The worst-hit area is the center of the state, especially the Central Valley that produces many of the vegetables, fruits, and nuts that appear on dining tables throughout the U.S.—and the world.
Visualizing water usage with groov:
As an Australian living in southern California I have been conflicted lots of times driving around seeing green lawns in baking hot sun.
When we moved to California from Australia in 2008, one of the worst droughts in history was still very much a huge issue for Victoria, the state we lived in. So when we arrived, the seemingly endless sea of green really, really surprised us all.
Australians have had little choice but to let their lawns brown off (often totally die) in the summer for many, many years...... It's just a fact of life of living in a sunburnt country.
As soon as we were able to buy our own home, I knew that monitoring our water usage was up near the top of my to-do list.
The challenge was how to share the data with the family, my wife and two teenage kids.
