California and Texas, the two most populated states in the USA, have been issuing water use restrictions due to devastating drought over the course of the last two decades. New innovations in wastewater management and infrastructure are viewed as the solution to these problems. Wade Miller, executive director of the Water Reuse Association, believes that currently only 7% of all US wastewater is being recycled. Miller optimistically states, however, that this number can increase past the 50% mark in the next decade if the technology and demand stay constant for long enough. With the current state of drought and water scarcity in the United States, these innovations are invaluably important.
A European firm has developed over the course of the last decade a process called “Direct Inline Pumping” which solves almost all problems associated with the current state of municipal wastewater infrastructure. The system does not produce Hydrogen Sulfide as do American systems, and so it has no need for the expensive plastic linings that American recycling plants line their concrete tanks with. The entire system is stainless steel, and so it requires no other expensive corrosion resistant material. The pumps shred debris themselves and are controlled by automated self-cleaning processes, so the pumps do not need to be protected from in-fluent sewage debris. The system has two motors, and so there is no need to worry about the need for backup, as the system can expend efficiency up to 200% baseline. The pump as a whole is believed to be 2 to 4 times more efficient than a traditional wastewater pump. The footprint of the system is small, and all electric components can be stored underground for both longevity and aesthetic reasons. The lack of hydrogen sulfide release leads to little or no released odor. Lastly, the system is equipped with provisions to make future expansion less involving.
