Us, S Africa & Aus Turding (Sewage) Wastewater Into Drinking Water

Recommended Posts

Turd skimming alert !

Until very recently, we used to point to the only one DPR (direct potable reuse)

scheme in the world, which has been operating in Namibia since 1968. But since 2011, new schemes have come online in the US at Cloudcroft (New Mexico), Big Spring (Texas) and Wichita Falls (Texas).

More significantly, a number of very large Californian cities such as San Diego, Los Angeles and Sacramento are now all actively considering the development of DPR schemes as a major contributor to future water supplies. Major changes to regulation (such as the California Water Code) have been implemented to facilitate these potential projects.

This has been accompanied by significant research efforts on the part of the US water industry to address a number of key issues including enhanced treatment process reliability, regulatory requirements and issues related to public perception and acceptance.....

Reusing highly treated municipal sewage effluent is not a new idea. It has traditionally been achieved by a process known as indirect potable reuse (IPR). Examples of unplanned IPR exist throughout the world, such as in Adelaide. In such cases, conventional sewage treatment plants discharge effluents to rivers (in Adelaide’s case into the Murray-Darling Rivers), which are then used as drinking water sources for cities downstream.

Alternatively, planned IPR usually involves treating the sewage effluents to a very high degree by advanced water treatment processes before releasing the purified water to a lake or groundwater system used for drinking water supply.

While planned IPR has been an important water supply strategy for a number of decades, an alternative approach, known as direct potable reuse (DPR) is now rapidly gaining favour in countries including the US, South Africa and Australia.

This process refers to taking treated municipal wastewater from a sewage treatment plant and, after further treating it to a level suitable for drinking, re-depositing it directly back into a drinking water distribution system. It differs from IPR by not discharging the water back to an environmental system, such as a river, lake or aquifer,.........

Interesting discussion on Rad 4 about Texas Experience with DPR

Meanwhile, to preserve water supplies in Wichita Falls evaporation suppressants are being sprayed onto reservoirs and water companies say they've started 'direct potable reuse' - reducing the stages between flush and faucet - which has garnered an interesting response.
