Industrial Wastewater Canada sizes and supplies oil & gas / produced water for plants in Ottawa, Ontario. Local demand is driven by high-tech, food processing, federal facilities, biotech, discharging under Ottawa's sewer-use rules toward Ottawa River. Quote requests with flow rate and effluent type get a sized proposal.

Oil and water separate on their own, given time. The entire discipline of oil and gas wastewater treatment exists because nobody in the industry has that time, and because the last few percent of oil refuses to leave without help. Free oil rises and skims easily. Dispersed droplets need coalescing plates or gas flotation. Emulsified oil, stabilized by production chemicals and shear from pumps, needs chemistry to break before any mechanical device can touch it. Knowing which fraction dominates your stream decides the equipment, which is why we ask for an oil-in-water analysis before we quote anything.
The applications span the value chain. Upstream, produced water from Alberta and Saskatchewan wells carries oil, solids and dissolved salts, and is treated for reinjection, disposal, or reuse in waterfloods, where oil carryover fouls injection formations. Midstream terminals and truck washouts generate slop oil and tank bottoms. Downstream, refineries run API separators as the first line, followed by dissolved gas or air flotation ahead of biological treatment. Gas plants add their own stream: amine and glycol wastes that behave nothing like produced water and should never be mixed with it.
Our equipment for this sector includes API oil water separator packages built to the API 421 gravity-separation design method, corrugated and inclined plate coalescing separators for tighter footprints, induced and dissolved gas flotation units, skimmer systems, and coalescing filter vessels for final polishing where discharge or reinjection specs demand single-digit oil concentrations. For remote batteries and early-production facilities the package arrives skid-mounted and winterized.
Alberta Energy Regulator directives, Saskatchewan disposal rules and federal offshore regulations each define oil-in-water limits differently, so we design against your specific approval rather than a generic number.
Send us the analysis, the flow range and the destination of the water, whether that is disposal well, waterflood or surface discharge. The proposal that comes back will name the separation stages, the expected outlet quality at each, and the turndown behaviour, because oilfield flows never stay at design point for long. A practical note on solids: produced sand and fines shorten the life of every separation stage, so where the well history shows sand production we put hydrocyclones or filtration ahead of the separator rather than letting the API vessel become a settling basin.
Ottawa's wastewater profile is unusual for a city of more than a million: alongside conventional food processors sits the largest concentration of federal facilities, research institutions and laboratories in the country, each generating small but chemically awkward waste streams. Sewer Use By-law 2003-514 governs what reaches the Ottawa River via the city's treatment plant, and it treats lab solvents, photographic chemistry and biotech media with the same rigour as a factory outfall. Small flows, complicated chemistry The typical Ottawa project is not a 1,000 m³/day food plant. Sewer Use By-law 2003-514; large institutional and lab wastewater segment. That is the regulatory backdrop for oil & Gas / Produced Water in Ottawa: equipment gets sized against the local limits on the route to Ottawa River, not against a national average.

Ottawa's industrial wastewater market is dominated by federal labs and biotech facilities discharging small, chemically awkward streams under Sewer Use By-law 2003-514, work that rewards instrumentation over sheer tank volume. In Ottawa, the plants asking about oil & Gas / Produced Water are mostly in high-tech, food processing, federal facilities and biotech, and each of those sectors puts a different load on a treatment train. Sewer Use By-law 2003-514; large institutional and lab wastewater segment. Direct discharge toward Ottawa River instead requires an Environmental Compliance Approval from Ontario's Ministry of the Environment, Conservation and Parks. A metro of Ottawa's size runs enough industrial flow that the municipal plant polices its intake closely, and surcharge invoices arrive on schedule. Projects in Ottawa tend to be one-of-a-kind rather than repeat configurations, which is exactly the case where sizing from measured effluent data matters most.
Everything you need to know about our services.
Yes. Industrial Wastewater Canada sizes and supplies oil & Gas / Produced Water for plants across Ottawa and the surrounding region. Most local demand comes from high-tech, food processing, federal facilities, biotech. Send a quote request with your flow rate and effluent type and a sized proposal follows.
Sewer Use By-law 2003-514; large institutional and lab wastewater segment. It is a 5 to 50 m³/day stream from a vaccine facility, a federal research campus or a microelectronics fab, where the challenge is characterization and neutralization rather than sheer volume. That favours compact, well-instrumented systems: pH control with real redundancy, effluent holding for batch certification before release, and logging the by-law inspector can audit. Plants discharging to the municipal sewer answer to that regime; anything released directly toward Ottawa River needs an Environmental Compliance Approval from Ontario's Ministry of the Environment, Conservation and Parks. We size equipment against whichever limit governs your outfall.
From your numbers, not from the city's. We start with measured flow and effluent characterization, then check the result against Ottawa's local limits. A processor in a city of 1,017K with high-tech as the dominant sector rarely has the same loading profile as its neighbours, so treatability data drives the selection.
There is no list price; every system is sized and quoted per project. The economics are local, though. Food and beverage plants along the city's east end still need classic BOD reduction, and we serve both ends of that spectrum. Payback in Ottawa is usually calculated against those surcharge and compliance costs, and the quote spells that comparison out.
Flow, contaminants, discharge limit. An engineer replies with a sized treatment train and a quote — no obligation.
