National Water and Wastewater Conference

In only a few weeks, the National Water and Wastewater Conference is being held in St. John’s, Newfoundland, from November 5-8. The SanEcoTec team has already begun preparations for the Conference where Robert Tyssen, Engineering Project Manager, will be presenting a Case Study on sustainable approaches to drinking water treatment in Newfoundland and Labrador.

Robert will be discussing the strategy behind AVIVE™ Water Programs and their applicability in remediating water systems with challenges like Sunnyside, a small town in Newfoundland where AVIVE™ is used as the municipal water treatment.

Newfoundland and Labrador struggles from major water challenges. In May 2015, a few months before the installation of the Sunnyside AVIVE™ System, there were 216 provincial boil-water advisories[1]. Due to a combination of the chlorine-based water treatment used widely across Newfoundland and elevated levels of organic content in the source water, the province also had many instances of unacceptable levels of disinfection by-products (DBPs). Chlorine, upon contact with organic matter, forms DBPs. There are 600 known DBPs, such as trihalomethanes (THM), but only 11 are regulated. Eight are known carcinogens.

Sunnyside presented the perfect testing ground for SanEcoTec and AVIVE™, as it represented all the challenges of the province in one small community. Sunnyside, under a mandatory boil-water advisory (BWA), faced excessively high chlorine DBPs and its surface water source was directly impacted by variant and extreme weather conditions. Not only did the nature of the source water present challenges, but the Town also had a long distribution network and lengthy hydraulic retention times.

AVIVE™ Water Programs are comprehensive water solutions that incorporate expert knowledge, a silver-ion stabilized hydrogen peroxide called HSP, advanced measurement and control systems and other innovative technologies.

Robert’s presentation is on Tuesday, November 7.
