Fire Department's Water Re-use Project wins national environmental award

This video was shot in July, 2010. Parts of it focus on the Water Re-Use Project. The sound isn't perfect, but there are good visuals of Firefighters using the water from the treated wetlands.

A first-of-its-kind system that utilizes the water from a man-made wetland for firefighting training excercises, which is then and then recaptured, treated and reused has won a national environmental award.

The Calgary Fire Department has won the National Municipal Environment Award from the Canadian Association of Municipal Administrators for the Water Re-use Project at the Fire Training Academy in the Calgary's southeast.

“We are very pleased that we have been able to implement such an environmentally responsible and sustainable program into our operations,” said Acting Fire Chief Ken Uzeloc. “The fact that it is now attracting recognition from our counterparts across Canada is a real honour.”

The Calgary Fire Department's training operations use up to 150 million litres of water per year. In essence, the Training Academy will virtually cease consumption and waste of potable water for training exercises.

Recognizing an opportunity to reduce its environmental footprint and to participate in The City’s 30-in-30 Water Efficiency Plan (to reduce Calgary’s per capita water consumption by 30 per cent from 2003 volumes by the year 2033) a system was constructed to capture and reuse the large quantity of water expended by the Calgary Fire Department’s Training Academy in practice fire exercises.

The City of Calgary’s Parks Department assisted in the design of the treated wetland and associated infrastructure and will operate the water treatment system, as well as oversee the irrigation and maintenance of the grounds.

“This project was and is a unique partnership between the Fire Department and Parks," said Anne Charlton, Director of Parks.
"It took the skills of landscape architecture, engineering and irrigation water management and combined them in a new, more industrial way to realize a very sound environmental project for Fire Training. We’re delighted to have been part of this very successful project.”

The systems works through a series of ponds that capture, treat and put water used in training exercises back into an internal hydrant system. There are three reservoirs that water must pass through before it can be put back into the system and reused again.

Using gravity, the first pond collects spent water from training courses on the tarmac area. The water is then pumped into a second shallow treatment wetland. Third, the water goes into the clean water reservoir. This is covered to keep the water clean and to keep fowl off the water. From here, this non-potable water then goes into a pump system to supply the hydrants at up to 40,000 litres per minute.

The clean water reservoir is also both clean enough and deep enough to accommodate the Fire Department’s Aquatic Rescue Team and will be used as a dive tank to conduct dive and water rescue training on site. Eight times the size of a traditional backyard swimming pool, serves as a year-round training facility.

A fourth pond captures water for irrigation. This storm pond receives water from the recycle system overflow, parking lots and building roofs. This pond stores up to three million litres of water for irrigation and has the capacity to store up to another four million litres of water in the event of a storm surge.

A final system upgrade includes the installation of a training manifold system, which allows the Fire Department to train pump operations without one drop of water hitting the ground. Since it’s a closed-circuit system, no water is lost through evaporation. Training can take place year-round without putting ice on the tarmac or wasting water.

The Calgary Fire Department’s Water Re-use Project, which began construction in June 2009 and opened July 2010, is the first of-its-kind in Canada.

The Calgary Fire Department’s Water Re-use Project has also been named a finalist for other awards including, the Globe Awards for Excellence in Urban Sustainability and the Emerald Awards, which will be given out on June 15th in Edmonton.
