27 June 1963
Thursday, 27 June 1963 was a sweltering, hot day. Well-dressed dignitaries attending the official launch of Ottawa’s Green’s Creek sewage treatment facility were wilting in the sun. Mayor Charlotte Whitton told speakers to be brief, quipping that given the $8 million cost of the plant, the city couldn’t afford to pay damage claims for sunstroke. A few minutes later, George McIlraith, Liberal MP for Ottawa West, told the assembled crowd that the plant ended the “desecration” of the Ottawa River. He then pressed a button, sending thousands of gallons of Ottawa waste water into the facility for processing.
McIlraith was wrong. The opening of the Green Creek plant did not put an end to the desecration of the Ottawa River caused by the dumping of sewage. It wasn’t even the beginning of the end, but at least it was a beginning.
In the early 1960s, the Ottawa River was a national disgrace. Up and down its length, raw sewage and industrial waste poured in from communities on both sides the river. High fecal coliform counts often rendered the water dangerous to drink and to swim in. Fish kills were common.
The problem was not new. Ever since settlers arrived, the Ottawa River had used as a dumping ground for all sorts of human and industrial waste. When the lumber industry had been at its height during the late nineteenth century, the mills on the Chaudière annually dumped countless tons of sawdust and other waste wood into the river. Immense sawdust shoals collected in quiet bays, blocking navigation, including at the entrance to the Rideau Canal locks. Much settled to the river bottom stifling fish spawning grounds. There, the sawdust rotted, releasing foul-smelling fumes of methene that exploded with disturbing regularity, risking the lives of unsuspecting boaters above.
After decades of prevarication, public pressure finally forced the government to confront Ottawa’s lumber barons and deal with the sawdust nuisance. By the beginning of the twentieth century, this problem had largely been resolved. Unwanted wood and sawdust were burnt in large incinerators, thereby alleviating water pollution, albeit at the expense of worsening air pollution.
But nothing was done about other forms of industrial effluent and human sewage that entered the Ottawa River. With the growing number of people living along side the Ottawa River, water quality continued to deteriorate.
As early as 1898, an expert from the Public Works Department of Ontario urged Ottawa and other municipalities to purify sewage water by filtering it through two layers of coke and a bed of sand. Two years later, the Ottawa Citizen remarked that the capital had not yet adopted any improved system of disposing of its sewage, but that this was a problem city council would eventually have to deal with. It noted the direct link between disease and sewage and said that “the old system” of draining sewage directly into some body of water had been discarded elsewhere with beneficial results. Since London, England began to chemically treat its sewage in 1890, the newspaper commented that Thames’s water quality was improving, and fish were returning.
In Ottawa, nothing was done.
Almost thirty years later in 1929, the Ottawa Citizen opined that it “may be timely,” to think about sewage disposal, musing that there must be a limit to the amount of sewage that could be poured daily into the Ottawa River. The newspaper postulated that federal or joint provincial action would eventually have to take place. Given this, it suggested that Ottawa explore how it might dispose of its sewage “in some less offensive way that by polluting the Ottawa River.” The newspaper also hoped that upstream communities would do likewise, as they were dumping their sewage into Ottawa’s drinking water.
Nothing was done.
In 1937, the Ottawa Citizen described Canada as “backward” in the field of sanitary science. It likened Ottawa to a remote mining camp in the way it treated its sewage. As a consequence, the Ottawa River was “impregnated with sewage.” While cleansing the Ottawa River would require interprovincial agreement, no jurisdictional difficulties stopped Ontario from protecting the Rideau River, or Quebec from protecting the Gatineau River. The newspaper urged action.
Nothing was done.
In 1944, a joint parliamentary committee recommended to Parliament that the federal government share in the cost of constructing a sewage disposal plant in Ottawa. But the following year, Ottawa’s Board of Control, which operated like a municipal cabinet, wasn’t sure that a sewage disposal plant was a priority. Ottawa’s Mayor Stanley contended that unless other communities on the Ottawa River, particularly Hull and Aylmer, also treated their sewage, there was little advantage for Ottawa to go it alone.
The Ottawa Citizen ridiculed Ottawa’s position, saying that it was obvious that Ottawa should act without delay to clean up its own portion of the Ottawa River, and that if it did so, the city would be in a strong position to make representations to other communities to join together in the common cause “of an unpolluted flow along one of Canada’s noble and historic rivers.” The newspaper opined that city council was evading “the unsavoury fact that Ottawa’s system of sewage disposal [was] medieval and a disgrace to a modern city.”
Nothing was done.
In 1949, a Toronto consulting firm, Gore and Storrie, issued a report on Ottawa’s sewage and water system for Ottawa’s Planning Board. The consultants made a number of recommendations, including a prohibition on the dumping of sewage and industrial waste into the Ottawa River upstream from the Chaudière Falls and as far as possible along the Rideau River, the separation of septic and stormwater sewers in all new and undeveloped areas, and the construction of a sewage treatment plant at Green’s Creek in Gloucester Township to handle waste from the city of Ottawa.
This report gained some traction. In 1951, Ottawa’s purchased a 320-acre site at Green’s Creek in Gloucester Township as the site for its future sewage treatment plant in line with the Gove and Storrie report. But further action was slow.
In 1954, Dr. Lucien Piché, a University of Montreal chemistry professor, said that the Ottawa River was “an open sewer,” its waters “unsuitable for any use whatsoever,” owing to the “callous” dumping of raw sewage by municipalities along its banks. Piché detailed the main contributors to the damage in the Ottawa area. These included: wood waste and residues, including sulphite liquor, from two E.B. Eddy pulp and paper plants, mixed sewage from a metropolitan area of 300,000 people in Ottawa, Eastview and Rockcliffe; mixed sewage from Hull and South Hull with a population of 45,000; and sewage from Gatineau, including the wood waste, and residue from the Canadian International Paper Company. Of course, inflows of sewage and industrial effluent didn’t stop there. The Ottawa River at Hawkesbury, downstream from Ottawa, was singled out as being in particularly vile shape. In addition to sewage, both locally produced and imported from upriver, fouling the river, the waters in the community had turned “wine-red” due to effluent from another plant owned by the Canadian International Paper Company.
In 1956, it looked like there would finally be action. The federal government, along with the Ontario and Quebec governments and Ottawa’s City Council under Mayor Charlotte Whitton were in agreement; pollution control would take priority over other city improvements. Plans were drawn up to build huge sewers to divert Ottawa’s raw sewage from the Ottawa River to a treatment plant at Green’s Creek. These plans, with an estimated price tag of $25.5 million, were submitted to the Ontario Water Resources Commission for its approval. The city also applied to the federal government for financial aid.
But a change in municipal administration with the election of Mayor Nelms in 1957 caused these plans to be put on hold. While acknowledging Ottawa’s responsibility for polluting the Ottawa River, Nelms said that Ottawa could not afford the project of that magnitude, and to undertake it would impair the city’s ability to address other development needs.
Ex-Mayor Whitton was livid. In her weekly column in the Ottawa Citizen, she thought the new City Council was giving in to big developers who didn’t want to pay sewage charges. The Ontario Water Resources Commission, the provincial agency that approved major municipal water and sewage projects, was similarly unimpressed. The Commission insisted that a sewage treatment plant was the highest priority, and sent a letter to Ottawa City Council in late 1957 stating that it would withhold permission for new sanitary sewers to serve new sub-divisions until a satisfactory program had been developed to address the sewage problem.
Many Ottawa Council members were incensed by the Commission’s action, saying that it was “arbitrary, mandatory coercion.” This view was also expressed by Robert Campeau, one of the big developers affected by the order. But the letter worked. Within months, the required detailed plan was unveiled, consisting of the construction of an elaborate network of tunnels to intercept sewage from existing sewers that would redirect the flow to a sewage treatment plant at Green’s Creek. The project would serve Ottawa, Eastview (Vanier), Rockcliffe Park, as well as portions of Nepean and Gloucester Township.
It still took several years for the project to get underway as the various levels of government haggled over financing. In the end, the federal government provided a $5 million grant though the National Capital Commission while the Canada Mortgage and Housing Corporation providing a cheap $10 million loan. In the meantime, little Nepean got a jump on Ottawa, constructing a sewage treatment plant near Shirley’s Bay in 1960. This plant was designed to service much of Nepean Township, including Lynwood Village, Manordale, Merivale, parts of Bells Corners, and the new Northern Electric Company Research buildings.
On 14 June 1961, it was Ottawa’s turn. Charlotte Whitton, by now returned to the mayor’s chair, happily plied a shovel to break ground at the site of the $8.5 million Green’s Creek sewage treatment plant. Irascible as ever, Whitton complained that the NCC would likely get all the credit.
The sewage treatment project consisted of four parts: the main building and related structures ($3.5 million); the primary digestion tanks and sludge lagoons ($4.6 million); a pumping station ($0.3 million); and an elevated water tank ($0.1 million) for a total of $8.5 million. The Green’s Creek plant was designed to handle an inflow of 40 million gallons of sewage daily from a population of 350,000. However, it could be expanded to handle 75 million gallons from a population of 590,000.
Additional contracts with a value of $12 million were tendered for new sewers, including the construction of the 2.44-mile-long interceptor sewer from Fleet Street in LeBreton Flats to John Street in New Edinburgh, designed to “intercept” sewage from the existing network of sewage feeders and collectors. An outfall sewer, eight feet in diameter and 4.8 miles long, was also constructed from John Street to the Green’s Creek sewage treatment plant. Construction of both the interceptor and outflow sewers required tunnelling deep underground—as much as 185 feet below ground level at Rockcliffe Park—often through solid rock.
Initialy, Ottawa’s sewage only received primary treatment, which included the removal of solids, grit and grease. The remaining liquid was then chlorinated to kill any bacteria before being pumped into the Ottawa River. Secondary treatment was to come later.
The treatment of Ottawa’s sewage had a dramatic impact on the quality of the water in the Ottawa River. Just two years after the Green’s Creek plant commenced operations, the Ottawa Journal reported that the Ottawa River was on the way to rehabilitation. However, many communities along the river continued to dump raw sewage into the Ottawa River, including Pembroke, Renfrew and Arnprior, upstream of Ottawa on the Ontario side, and Aylmer and Hull on the Quebec side. Two industrial plants on the Quebec side—E.B. Eddy’s and the Canadian International Paper Company, which were accused of generating as much effluent as a city of 2.5 million, were still pouring their waste into the Ottawa River.
It was decades before all communities on both sides of the Ottawa treated their sewage. It took until 1982 for the Gatineau Wastewater Treatment Plant to be commissioned. The small village of Quyon was reportedly the last community on the river to treat its sewage with a plant built in 2004. However, even with all communities finally treating their waste water, raw sewage continued to flow into the Ottawa River during the spring thaw and during thunderstorms due to older stormwater drains being interconnected with the sanitary sewers (combined sewers). The sanitary sewers were not capable of handling sudden large surges in stormwater, leading to emergency outflows of untreated sewage into the Ottawa River to avoid back-ups. This problem in Ottawa was mostly addressed in late 2020 with the opening of the Combined Sewage Storage Tunnel. The CSST is designed to temporarily hold surges in wastewater from the combined sewers so that the Green’s Creek sewage facility, today known as the Robert O. Pickard Environmental Centre Wastewater Treatment Plant, is not overwhelmed leading to back-ups. Work continues on separating the stormwater and sanitary sewer systems.
Waste water at the Pickard Centre receives primary and secondary treatment and is disinfected with sodium hypochlorite before being returned to the Ottawa River. The centre meets all provincial guidelines. If you are wondering, the extracted biosolids (over 50,000 metric tonnes in 2022) are use to enrich agricultural lands.
Today, the Ottawa River’s water quality is infinitely better than it was in the 1960s. However, according to the Ottawa Riverkeeper, a grassroots charity, there is no one government agency charged with monitoring its health. Instead, testing is done in a piecemeal fashion, which makes it difficult to monitor long-term trends in the quality of the river’s water. We do know, however, that the legacy of past abuse lingers. Large fish, especially predator fish, that live in the Ottawa River are contaminated by heavy metals, such as mercury. The Ontario government advises pregnant women and young people to strictly limit their monthly consumption of certain types of fish caught there.
