Yes, you read that correctly - the dreaded kitchen sink water being reused in his garden! And with a variance from the state plumbing code to boot.
The article is silent on how much the variance cost him, but on the basis of the following information contained in the article, it was probably less than the $90 that Oregon demands for something less sophisticated:
Thesen said that for Palo Alto to approve the design, he had to promise a number of improvements, including a high-level water alarm which will sound if, for example, he left the sink running and it started flooding his yard....For it to be rolled out to the masses, though, Thesen’s pilot test has to be a success. “The city is saying hey, we are promoting people who want to put in place pilot systems,” said Thesen. “We recognize the benefits, we will not say no to putting in systems like this, just give us the data.”
