Environmental Fail: San Francisco Low-Flow Toilets Sludging and Stinking Like Rotten-Eggs

San Francisco’s implementation of low-flow toilets has turned into a multimillion-dollar plumbing nightmare. Using less water during the flush of the toilet has resulted in an increase of sewage sludge backing up in sewer pipes. The result has been a rotten egg or Hydrogen Sulfide stench near AT&T Park and other areas of San Francisco, especially during dry summer months.

San Francisco is upgrading it sewer system at a cost of $100 million and is using sodium hypochlorite as an odor fighter and disinfectant. Unfortunately, 8.5 million pounds of bleach are being poured down the drain for the cause of saving 20 million gallons in consumption of water.
