State of The Rainwater Supply Address

So far this year I've had .67" of rain.  Out of a total storage capacity of 21,000 gallons - I have 10,850 gallons on tap.  90,105,69,0,B

What has been your lowest amount?
Have you ever had to bring in water from outside sources?

Very impressive!

If I was there I would probably buy a used mini excavator for under 10k and start digging for water, maybe create a pond..

Zole...I have not had to haul any water since I got the greenhouse built and catchment hooked up. Since then I have never had less than 9,000 gallons on tap. Antidesign...ponds evaporate too quickly out here to make them worth the labor and expense.

John, What is your wettest month? Here in Austin area it is May.
How hot does the water get the tanks in mid summer?

John Wells said...

June - October is when we tend to get rain. Water at the top of the tanks gets warm but it is cool coming out the bottom.

Dang, less than an inch. Now I know why you have that much storage.

Mr. Wells prudently provided to accommodate the potentially most catastrophic contingency. People could learn from him how to become a well-adapted desert dweller.

Whats your typical humidity during the day / the seasons? Have you ever revcorded this like you do with temps / wind ?

Integrating all psychometric conditions out there over the average year, the net evaporation (evaporation minus precipitation) from a pond out there is about 40 inches per year.

There is some variation based on wind conditions.

Going from memory here.
