In yet another example of why prudence is necessary on the behalf of law makers, who might have a little more faith in the market getting it right the first time: San Francisco spends $14 million on bleach after eco toilets cause a stink Less water per flush means less water pushing sludge along through sewers. Now California has spent $14 million (aside from $100 million in previous attempts to deal with this problem) on bleach that will eventually flow into the San Francisco bay. That doesn't sound very environmentally friendly. See Rand Paul's questioning earlier this week on the issues of low-flush toilets and efficiency standards for light bulbs here. "We don't even save money. We flush 'em ten times. They don't work."
