*Qatar could develop a number of small, decentralised sewage treatment and water-recycling units instead of relying on centralised plants that receive all the greywater and blackwater through a communal system* is what a UNESCO advisor is recommending. *Independent sewage treatment facilities, if installed at housing complexes, shopping centres, and institutions with a large number of employees, would streamline the entire process and save huge quantities of fresh water*.
Previous postings have discussed greywater reuse in the Middle East, specifically this excellent document published by the Canadians and this posting about the importance of greywater to national security in the Middle East. Dr. Peter Gleick of the water thinktank Pacific Institute came out with a comparable challenge to centralized water distribution and wastewater treatment in this posting, suggesting *The old centralized model of water purification, delivery, and wastewater treatment could use some competition from small-scale, distributed systems that may produce better local benefits. This includes expanding local efforts to use greywater*. And who can forget this classic posting on the challenge to the wastewater treatment industry's local pocketbooks with decentralized water/wastewater systems.
How big is the market? According to this article, *Distributed water purification could, potentially, also finally open up the long-awaited flood of investment into water...The field of water treatment could be worth hundreds of billions of dollars a year...A shift to distributed water and private sector customers could accelerate the market. You could even see companies like IBM, Bechtel or Siemens offering the complete off-the-grid package to new housing developers and contractors*.
Contesting the status quo in Qatar just might be what it takes to make a shift from *protecting the power* of the proponents of centralized water/wastewater treatment. According to the UNESCO official studying the Qatar situation, the region is very dependent on desalination plants that *...are not really clean factories...They cause brine pollution in the marine environment with the output of higher saline water, which in turn brings biodiversity down...The desalination plants, which cause thermal pollution by heating the water a little bit, are also responsible for substantial air pollution as they are using fossil fuel*.
“Of course, the more water needs to be produced, the more these plants will pollute the air. So taking care of the waste water, trying to recycle it, is in all of our interest, it is in the interest of our environment, and human health,” Dr. Boer added.
