Oil & Gas / Produced Water in Montreal, Quebec
Industrial Wastewater Canada sizes and supplies oil & gas / produced water for plants in Montreal, Quebec. Local demand is driven by aerospace, food & beverage, pharmaceuticals, petrochemicals, discharging under Montreal's sewer-use rules toward St. Lawrence 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.
Applications across the value chain
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.
Separators built to API 421
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.
Limits differ by regulator
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.
Where your water goes next
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.
An industrial discharger in Montreal answers to two regulators at once. The metropolitan community's By-law 2008-47 governs what the city's sewers will accept, while Quebec's environment ministry (MELCCFP) issues the industrial attestations that direct dischargers to the St. Lawrence must hold. Quebec MELCCFP industrial discharge attestations; CMM By-law 2008-47 governs sewer discharge across the metro. That is the regulatory backdrop for oil & Gas / Produced Water in Montreal: equipment gets sized against the local limits on the route to St. Lawrence River, not against a national average.

Oil & Gas / Produced Water on the ground in Montreal
Montreal industrial wastewater lives under a double layer of regulation, CMM By-law 2008-47 for the sewer and MELCCFP attestations for the St. Lawrence, and every compliance file has to stand up in French. In Montreal, the plants asking about oil & Gas / Produced Water are mostly in aerospace, food & beverage, pharmaceuticals and petrochemicals, and each of those sectors puts a different load on a treatment train. Quebec MELCCFP industrial discharge attestations; CMM By-law 2008-47 governs sewer discharge across the metro. Direct discharge toward St. Lawrence River instead requires a ministerial authorization under section 22 of Quebec's Environment Quality Act. A metro of Montreal's size runs enough industrial flow that the municipal plant polices its intake closely, and surcharge invoices arrive on schedule. We quote oil & Gas / Produced Water in Montreal often, and the sizing conversation usually starts from a surcharge bill or a compliance letter rather than from a catalogue.
FAQ
Frequently Asked Questions
Everything you need to know about our services.
Do you supply oil & Gas / Produced Water in Montreal?
Yes. Industrial Wastewater Canada sizes and supplies oil & Gas / Produced Water for plants across Montreal and the surrounding region. Most local demand comes from aerospace, food & beverage, pharmaceuticals, petrochemicals. Send a quote request with your flow rate and effluent type and a sized proposal follows.
What discharge rules apply to industrial wastewater in Montreal?
Quebec MELCCFP industrial discharge attestations; CMM By-law 2008-47 governs sewer discharge across the metro. Aerospace surface-treatment shops, food and beverage plants, pharmaceutical manufacturers and the east-end petrochemical corridor all navigate this double layer. Two regulators, one discharge point The practical consequence is paperwork with teeth: a pretreatment system here has to be documented in French, matched to the attestation's specific parameter list, and able to prove itself with composite sampling rather than grab samples. Plants discharging to the municipal sewer answer to that regime; anything released directly toward St. Lawrence River needs a ministerial authorization under section 22 of Quebec's Environment Quality Act. We size equipment against whichever limit governs your outfall.
How is oil & Gas / Produced Water sized for a plant in Montreal?
From your numbers, not from the city's. We start with measured flow and effluent characterization, then check the result against Montreal's local limits. A processor in a city of 1,763K with aerospace as the dominant sector rarely has the same loading profile as its neighbours, so treatability data drives the selection.
What does oil & Gas / Produced Water cost in Montreal?
There is no list price; every system is sized and quoted per project. The economics are local, though. Aerospace platers worry about chromium and cyanide limits measured in the hundreds of micrograms per litre; a brewery worries about BOD surcharges instead. We build the treatment train around the specific attestation or by-law schedule a plant holds, then set up the sampling and reporting so the compliance file writes itself. Payback in Montreal is usually calculated against those surcharge and compliance costs, and the quote spells that comparison out.
