Artificial lake calls for unique solution

In 1965, the Gingras family’s dream came true when they purchased a large camping site just outside of Montreal, Canada. And their dream has prospered — the site is now a regular summer holiday spot for hundreds of families, couples and youngsters.

Camping Domaine du Reve in Marieville, Canada has grown with the addition of playgrounds, water slides, canoe hire, volleyball courts, a baseball field, a skate park, and cooking and bathroom facilities. It also boasts an improved lake for swimming, water sports and games.

Because of the number of visitors who used the lake, a significant problem was keeping the water quality consistently high for the benefit of the campers.

“The problem we had to address was the growth of a specific type of organic plant material that stifles all other types of underwater plants necessary for aquatic life and natural filtration,” explains Emmanuel Ammadio from WaterTec, who coordinated the installation of new filtration equipment for the lake.

“The chemical balance of the water was heavily affected and the water became turbid. We tried the injection of specialty chemicals, but the cost and maintenance associated with this option was very expensive and time-consuming.”

The problem then had to be treated manually by emptying the entire 378 ML pond and removing the weeds that were affecting the water’s natural balance and filtration. Needless to say, this was an extremely large task to be performed every three months, which interrupted the visitors’ holidays.

Abdou Slaoui, general manager of Waterco Canada, says the artificial lake needed a unique solution.

“It takes two weeks to empty the lake and pull out all the weeds — so we were happy that Waterco’s Trimline Bag Filter C50 and Supatuf Filter 0.75 HP provided Camping Domaine du Reve with the improved filtration they needed so they did not need to tackle this huge task so often,” he says.

These two Waterco products were chosen to function alongside WaterTec’s 100% natural alternative to revitalise the water oxygenation. This innovative solution, which uses hydrolysis, helps regeneration of water and sanitation but is unable to be effective without a steady flow of 60 GPM and a good prefiltration to 50 µm. This is where the Waterco filter and screener come in.

“The filtration equipment was chosen based on energy efficiency, low noise level, small dimensions and, of course, reliability,” clarifies Ammadio.

“Once filtered, the water is oxidised through the hydrolysis reactor, creating a separation and flocculation of the contaminants while controlling the weeds. The production of hydrogen generated in the reactor also stabilises the pH, giving an even more powerful oxidising effect. A natural settling then brightens bathing water.”

With the new system installed in August 2015, the water quality has noticeably improved, looking cleaner and clearer by the day. Swimmers and staff alike at Camping Domaine du Reve are thrilled with the result.
