Wastewater cleaning bacteria find a good home in the igloo dome shaped Poo-Gloos, and offer an affordable way for small communities to treat their wastewater. The Poo-Gloos, made by Wastewater Compliance Systems (WCS), Salt Lake City, Utah, USA, are lined with a bacterial biofilm and placed in existing water treatment plants.

Each Poo-Gloo is 6ft (1.83m) in diameter, 3ft (0.92m) tall, with a 1ft high (0.3m) base with seven biofilm lined plastic domes inside each Poo-Gloo to maximize bacteria surface area. Inside the Poo-Gloos, heterotrophic bacteria digest raw sewage carbon-based materials and autotrophic bacteria take care of the ammonia and nitrogen compounds, with pump fed sewage and air piped into each Poo-Gloo. Other bio-films are being researched that could remove other harmful contaminants from the sewage.

Developed initially in 2002 at the University of Utah by Dr. Kraig Johnson, now chief technology officer for WCS, each Poo-Gloo plant costs around US$100,000-200,000 (€76,300-152,600) compared to millions for a conventional sewage treatment plant. They also require very little power to run, and could be powered by renewable energy which is possibly very good news for the thousands of municipal wastewater treatment ponds that have to meet tougher environmental standards.
