Oil Water Separators in Calgary, Alberta
Industrial Wastewater Canada sizes and supplies oil water separators for plants in Calgary, Alberta. Local demand is driven by oil & gas services, food processing, chemicals, logistics, discharging under Calgary's sewer-use rules toward Bow River. Quote requests with flow rate and effluent type get a sized proposal.
Every vehicle wash bay, machine shop, fuel depot and refinery in Canada faces the same line item in its sewer-use bylaw: oil and grease, typically capped somewhere between 15 and 100 mg/L depending on the municipality. An oil water separator is the standard way to meet that cap. It exploits the density difference between oil and water: flow slows inside the vessel, droplets rise and coalesce into a surface layer that gets skimmed, and cleaned water leaves from below.
Two designs, one choice
The choice that matters is between the two main designs. A gravity API separator is a long rectangular basin sized to Stokes' law, built to let droplets of roughly 150 microns and larger rise out. It is robust, tolerant of solids and easy to maintain, which is why refineries still standardize on it. A coalescing-plate separator adds inclined plate packs or oleophilic media that intercept far smaller droplets, down to about 20 to 60 microns, so it reaches better effluent quality in a fraction of the footprint. Our coalescing configurations hold effluent under 10 ppm oil and grease in free-oil service, and many sites pair an API basin with a coalescing polishing stage.
Above-grade, below-grade and API 421
We quote both, in above-grade and below-grade tanks, with API 421 compliant configurations where the specification calls for it. Options include oil-stop valves that close automatically when the oil layer reaches capacity, high-level alarms, and sludge baffles for streams that carry grit. What a separator will not do is remove chemically emulsified or dissolved oil; if your stream carries surfactants from a wash process, we will tell you plainly that you need chemical treatment or flotation ahead of the separator, because selling you a tank that cannot meet your limit helps neither of us.
Sizing from your real flows
Sizing depends on flow rate, droplet size distribution and oil type, which is why the search term oil water separator, at 480 searches a month in Canada, so often ends in a mis-sized purchase from a catalogue. Send us your flow, a recent lab analysis or a description of the process, and your discharge destination. We return a sized configuration, budget price and delivery timeline, reviewed by a process engineer before it reaches you, for any site in Canada. Installation support and commissioning are quoted per project, and replacement plate packs and media remain available for the life of the vessel. Below-grade installations ship with traffic-rated covers where the separator sits in a drive lane, and we keep skimmer parts and alarm components on the shelf so a maintenance call does not become a compliance gap.
Calgary sits at the junction of two wastewater markets. Inside city limits, well over a million people and a growing base of food processors, chemical blenders and logistics operators discharge under Wastewater Bylaw 14M2012, with the Bow River as the receiving water. Outside the city, the surrounding basin runs on produced water and work-camp utilities, a market with no municipal sewer at all. City of Calgary Wastewater Bylaw 14M2012; large produced-water and camp wastewater market in surrounding basin. That is the regulatory backdrop for oil Water Separators in Calgary: equipment gets sized against the local limits on the route to Bow River, not against a national average.

Oil Water Separators on the ground in Calgary
Calgary plants answer to Bylaw 14M2012 and a trout river with no assimilative capacity to spare, while an hour away the produced-water market needs wastewater treatment skids that run unattended at −30 °C. In Calgary, the plants asking about oil Water Separators are mostly in oil & gas services, food processing, chemicals and logistics, and each of those sectors puts a different load on a treatment train. City of Calgary Wastewater Bylaw 14M2012; large produced-water and camp wastewater market in surrounding basin. Direct discharge toward Bow River instead requires an approval under Alberta's Environmental Protection and Enhancement Act. A metro of Calgary's size runs enough industrial flow that the municipal plant polices its intake closely, and surcharge invoices arrive on schedule. We quote oil Water Separators in Calgary 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 Water Separators in Calgary?
Yes. Industrial Wastewater Canada sizes and supplies oil Water Separators for plants across Calgary and the surrounding region. Most local demand comes from oil & gas services, food processing, chemicals, logistics. Send a quote request with your flow rate and effluent type and a sized proposal follows.
What discharge rules apply to industrial wastewater in Calgary?
City of Calgary Wastewater Bylaw 14M2012; large produced-water and camp wastewater market in surrounding basin. Bow River limits meet oilfield volumes The Bow is a cold, clear trout river with little assimilative capacity to spare, so the city keeps its bylaw limits tight and its sampling frequent. Meanwhile an oil and gas service company an hour away may need to treat 500 m³/day of produced water to reuse or disposal standards with nothing but a skid and a generator. Plants discharging to the municipal sewer answer to that regime; anything released directly toward Bow River needs an approval under Alberta's Environmental Protection and Enhancement Act. We size equipment against whichever limit governs your outfall.
How is oil Water Separators sized for a plant in Calgary?
From your numbers, not from the city's. We start with measured flow and effluent characterization, then check the result against Calgary's local limits. A processor in a city of 1,307K with oil & gas services as the dominant sector rarely has the same loading profile as its neighbours, so treatability data drives the selection.
What does oil Water Separators cost in Calgary?
There is no list price; every system is sized and quoted per project. The economics are local, though. We design for both ends: sewer-compliance pretreatment for plants inside Calgary, and self-contained packaged systems for camps and well sites where winter operation at −30 °C is a design requirement, not an edge case. Payback in Calgary is usually calculated against those surcharge and compliance costs, and the quote spells that comparison out.
