ES&E NEWStain algae biomass at levels that do not produce toxins that pose a threat to hu-man or ecosystem health, said the EPA.
Since the 1990s, Lake Erie has seen an increase in algal growth that has compromised water quality and threat-ens the Lake Erie region’s recreation-in-tensive economy. The algal bloom in 2015 was recorded as the largest bloom this century, covering over 775 square kilometres in dense scum.
Through the Great Lakes Water Quality Agreement, Canada and the U.S. committed in 2012 to combat the growing threat of toxic and nuisance algae development in Lake Erie. They agreed to develop updated binational phosphorus reduction targets for Lake Erie by February 2016. The 40% re-duction targets are based on 2008 load-ing levels. Canada and the U.S. have committed to develop domestic action plans, by no later than February 2018, to help meet the new targets.

Greatario celebrates 30 years In 1986, Greatario built its first
glass-fused-to-steel water tank for Mid-hurst, Ontario. At the time, council was researching alternative water storage tanks to replace their deteriorating ones.
The community, primarily an agri-cultural region, was very familiar with the Harvestore glass-fused-to-steel structures for animal feed storage. Rec-ognizing their durability and longevity, council asked Glen Gregory, then pres-ident of Ontario Harvestore: “Can you store water in these tanks?” The answer was, yes.

ES&E NEWSport, the firm was able to construct their first potable water storage tank. Con-struction of the Midhurst tank began in the fall of 1986 and it was commis-sioned in 1987. Thirty years later, with only minimal maintenance, it continues to provide the community with clean, safe drinking water.
With the success of the Midhurst tank, Greatario Engineered Storage Sys-tems was developed as a sister company to Ontario Harvestore. The focus of the new company was to service water and wastewater requirements throughout eastern Canada.
In 1989, Greatario’s team came back to Springwater Township to build a
tank in Minesing. President, Scott Burn credits Greatario’s early success to their partnership with Springwater Township and the confidence the council had in the development of glass-fused-to-steel water storage tanks. Since then, over 425 tanks and domes have been built across Canada.

Digital initiative announced to help solve urgent
water challengesGE and American Water have formed
a new digital initiative to identify and explore advances in the “Industrial In-ternet of Things” to help solve pressing challenges in the water industry.
The initiative will include the use of GE’s Predix, a cloud platform built exclusively for industry that powers the Industrial Internet. The companies will collaborate to develop the next gen-eration of software and data analytics solutions to help the industry reduce the environmental impacts and operating costs associated with water production, treatment, transportation and delivery.
“We are developing software, ad-vanced predictive analytics and diag-nostic tools that will give operators the real-time data they need to better man-age their critical water infrastructure as-sets 24 hours a day,” said Heiner Mark-hoff of GE Power.
