The City of Saskatoon has suffered more than $1 million in losses and damages due to water contamination in the Aspen Ridge neighbourhood, a lawsuit alleges.

From Jan. 10 to Sept. 14, a “do not use” water advisory was in effect for 19 addresses in the Aspen Ridge subdivision. A black, petroleum-based substance, known as hydrocarbons, surfaced in fire hydrants in the area in December 2016.

A statement of claim filed Nov. 23 at Saskatoon Court of Queen’s Bench names Atlanta-based Mueller Water Products Inc. and Burlington, Ont.-based Wolseley Canada Inc. as defendants.

Mueller constructed the hydrants, which were delivered by Wolseley to the work site around spring 2014, according to the document delivered by the office of the city solicitor.

Hydrocarbons appeared in nine out of the 12 Mueller hydrants installed in Phase 2 of Aspen Ridge, which was physically isolated from Phase 1, according to the suit. At the time, people were only living in the initial phase.

The source of the hydrocarbons remained a mystery for months, forcing Aspen Ridge construction to cease for the winter before resuming in spring.

As the city investigated the source, residents in Aspen Ridge were required to use bottled water, water trucks, and temporary water lines.

In addition to hydrants, the contamination spread to the lead line from the water main and in some cases, hydrocarbons were found in the main water lines, according to the city.

“The City says that Mueller and/or Wolseley knew, or ought to have known, about the potential for the contamination substance to form in Mueller hydrants, and failed to warn the City of this dangerous condition,” the statement reads.

The city contends the companies should have known the hydrants would be connected to its potable water system.

The filing also states Mueller didn’t warn anyone of the potential contamination risk, “and failed to provide any information, procedures, or techniques that could minimize the risk.”

“The full extent of contaminated Mueller hydrants within the City of Saskatoon is not yet known,” according to the document.

None of the allegations have been proven in court. Neither of the defendants immediately responded to a request for an interview with Global News.

From the day they were served, the companies have 30 days to file a response with the court.

The city’s losses and damages are said to include the following:

• Costs of inspecting the water system;
• Cleaning up the contamination;
• Setting up temporary water lines;
• Providing water;
• Retaining experts to investigate the source of the contamination; and
• Identifying the substances.

Other damages are expected to be incurred prior to trial, according the claim.

After the hydrocarbons surfaced, Saskatchewan’s Water Security Agency required the city to inspect nearby hydrants and either remove and replace the affected infrastructure or bring in an engineering consultant.

Stantec Consulting was hired by the city for a preliminary investigation and remediation plan, ultimately finding the Aspen Ridge water supply met Canadian drinking water standards.

In May, a “do not use” order was issued in Saskatoon’s Rosewood area after contaminated Mueller fire hydrants were discovered.

The advisory resulted in temporary water lines being installed at the neighbourhood Costco. The city lifted the notice in August.
