A $40 million phosphorus recovery facility will be constructed by the Des
Moines Metropolitan Wastewater Reclamation Authority (WRA

under a plan presented to the city's Urban Design Review Board last week.

   - The WRA anticipates tougher state and federal regulations to limit
   phosphorus and is trying to get ahead of them, Larry Hare, the WRA's
   treatment manager, tells Axios.

Why it matters: Phosphorus is a naturally occurring element but when there
is too much of it — usually from fertilizers, manures or sewage — it can
lead to reduced oxygen in water. That can result in toxic algae that can be
harmful

to
humans and animals.

The intrigue: WRA's staff developed and patented a new method that absorbs
more phosphorus from wastewater, Hare said.

   - The facility will run an estimated three times more efficiently as
   compared to others that use more common techniques that involve chemicals.
   - It will reduce phosphorus in water cleaned by the WRA by an estimated
   80%.
   - The removed phosphorus will be converted into pellets and sold to
   fertilizer markets, likely covering the cost of the plant's future
   operating costs, Hare said.

State of play: The project has been under consideration for about five
years. It was delayed partly because WRA staff was studying how to make the
plant more efficient, Hare told Axios.

The big picture: The WRA is made up of 17 metro communities and is the
largest sewage treatment plan in Iowa.

   - Its efforts could have a big impact in reducing Iowa's levels of
   excess phosphorus that in recent years have contributed to thousands of
   miles of "dead zone

   as "red tide" in places like Florida.
   - The dead zone is an area of low oxygen that can kill fish and other
   marine life, according to the NOAA.

What's next: The WRA will seek construction bids for the project at its
southeast DSM facilities in coming months.

   - Completion is expected in 2025, according to the plans
