Population growth fills sludge lagoons to capacity

CALGARY – The city’s booming population growth is filling more than the suburbs: Calgary’s sewage lagoons are also close to overflowing.
The city pumps its biosolids from wastewater treatment facilities into the southeast Shepard sludge lagoons. Even through the city has a sophisticated system for turning sludge into fertilizer for farmer’s fields, the treatment program cannot keep up with the increasing volume of biosolids, the utilities committee heard Wednesday.
“We are very close to capacity for biosolids and we’re running out of room. We’re a growing city,” said Ald. Brian Pincott.
Planning for a massive composting facility partnered with water and waste services could be the answer.
“One of our solutions is our composting facility and looking how we partner. It’s about efficiency and cost savings,” Pincott said.
“The environmental liabilities of having organics in the landfill are astounding.”
