Designing a WEEDS System

What’s New?

Over the past year or so, several new water spray systems that are based on the WEEDS wildfire protection system have come online – two in California and one in Montana. A number of common questions and problems came out of these installations, and I’d like to take this opportunity to present the lessons learned.

Where are the plans for WEEDS?

Engineering a Miracle - The Story of WEEDS

“I dreamed that we had a fountain on our roof,” she said. “We’d just push this button and out would come this spray of water, pssssssht, far up into the air and all over the house.”

We both laughed at the idea. We were acclimating to the Southern California weather after relocating from the cool dampness of northern Europe, and were experiencing the punishing heat of August to October. Ramona is a hot place, and for some reason our home’s little microclimate is a bit hotter still. We’ve seen 100o in February, and had highs in the 100’s for a week straight. Our local record is 117o. It was not surprising that my wife, Diane Conklin, would dream of cool fountains. Having one on the roof, well, that was a bit odd.
