Uses
Most of the uses of water reclamation are non potable uses such as: Washing Cars, flushing toilets, cooling water for power plants, concrete mixing, artificial lakes, and irrigation for golf courses and public parks. Most systems run a dual piping system to keep the recycled water separate from the potable water.
Indirect water reclamation (water passing through a body of water first) will result in potable water usage. While, this is not practiced in the United States, it is in other countries such as Namibia.
Aboard the International Space Station, astronauts have been able to drink recycled urine due to the introduction of the ECLSS system. The system costs $250 million and has been working since May 2009. The system recycles wastewater and urine back into potable water used for drinking, food preparation, and oxygen generation. This cuts back on the need for resupplying the space station as often.
