Chinese car wash businesses in the Pinggu district of Beijing have switched to recycled water rather than using expensive drinking water. The reclaimed water is 1/16th the cost of the standard water, according to local news media.
The district’s 56 car washes began trucking in the recycled water from the water treatment plant in August. The companies also didn’t have a choice:
The district government implemented strict measures to control water consumption of these shops by expanding the use of recycled water in August, a report from Beijing Water Authority said on Thursday.
Two vehicles deliver recycled water from a local sewage treatment plant every day to all the car-wash businesses, and each shop has a container of water weighing about 1.2 tons. The vehicles can deliver 80 tons in total every day.
On the up side, the recycled water is much, much cheaper to purchase. While the tap water costs 160 yuan per ton (about $26), the recycled water is 10 yuan per ton ($1.63). It wasn’t clear from the Chinese news report why the water is so much cheaper, but it seems clear the recycled water isn’t undergoing the typical treatment processes.
Best advise the car wash employees not to drink from the hose.
