5 Best Septic Tank Companies in Winnipeg (2026) — Reviewed & Ranked
Septic problems don't wait for business hours. We reviewed every major septic pumping and cleaning company serving Winnipeg and surrounding communities — checking Manitoba's registered sewage hauler list, BBB profiles, service ranges, and emergency availability.
How We Reviewed These Companies
For this Winnipeg roundup, we looked at the factors that matter most to homeowners and property owners: whether the company clearly serves Winnipeg or nearby communities, the range of septic services listed, emergency availability, how transparent the site is about service areas and contact details, years in business when publicly stated, and third-party trust signals such as Manitoba's registered sewage hauler list and BBB profiles where available.
This is a public-information review — no company paid for placement. Every company listed here appears on Manitoba's registered sewage hauler list, which confirms they are legally permitted to transport and dispose of sewage waste in the province.
Septic problems don't wait for business hours. Whether you're a Fort Garry homeowner due for a routine pump-out, a rural property owner in the Perimeter who just had a backup, or a developer breaking ground on a new build outside the city's sewer grid, you need a company that shows up, knows the work, and is properly registered with the province.
We checked Manitoba's registered sewage hauler list, BBB profiles, and each company's own published service details to rank the five best options serving the Winnipeg area.

In Business Since: 1985 | Experience: 40+ years | BBB: A+ Accredited | Location: Headingley, MB (serves Winnipeg and area)
Manitoba Hauler List: Yes (registered as Kings Septic and Portable Toilet Service Inc.)
King's Services takes the top spot because it offers the strongest overall mix of experience, service range, and Winnipeg-area coverage. Serving the city since 1985, King's handles septic tank pumping, inspections, emergency septic service, and full system installations — making it one of the few local providers that can manage both routine maintenance and major septic work under one company. They appear on Manitoba's registered sewage hauler list as Kings Septic and Portable Toilet Service Inc., confirming full provincial licensing.
Pros
- ✓ 40+ years serving the Winnipeg market — among the longest track records locally
- ✓ BBB A+ Accredited — top-tier third-party trust credential
- ✓ Full service range: pumping, inspections, emergency calls, and complete installations
- ✓ Registered on Manitoba's provincial sewage hauler list
- ✓ Strong fit for both scheduled maintenance and urgent septic failures
Cons
- ✗ Based in Headingley rather than within Winnipeg proper — north-end response times may be longer

2. A-1 Environmental Services
Founded: 1951 | BBB Rating: A+ Accredited | Location: Winnipeg, MB
Manitoba Hauler List: Yes | Services: Septic tank cleaning, grease trap cleaning, liquid waste removal, emergency service
Visit A-1 Environmental Services →
A-1 Environmental Services is one of the oldest and most credentialed companies in this roundup. Operating since 1951, their septic offering goes beyond basic pump-outs to include grease trap cleaning, liquid waste removal, and high-pressure steam cleaning — services that make them a natural fit for commercial and light-industrial clients alongside residential customers. Their BBB A+ accreditation and spot on Manitoba's registered hauler list provide strong third-party verification of their legitimacy and standards.
Pros
- ✓ In business since 1951 — one of the longest-established operators in Manitoba
- ✓ BBB Accredited with an A+ rating — strongest third-party trust signal on this list
- ✓ Services extend to grease traps, liquid waste, and steam cleaning alongside septic
- ✓ Emergency service available
Cons
- ✗ Broader environmental-services focus — may feel less tailored for a simple residential pump-out
- ✗ Website covers many service lines; septic information is not as narrowly presented as competitors
Best for: Commercial and industrial clients who may need septic work alongside grease trap or liquid waste removal, and anyone who prioritizes a BBB-verified, long-established Winnipeg operator.
3. Biff's Septic & Portable Toilet Service
Emergency: 24/7 | Location: Stonewall, MB (serves Winnipeg and perimeter)
Manitoba Hauler List: Yes | Service Area: Winnipeg, Headingley, West St. Paul, East St. Paul, St. Andrews, Rosser, Rockwood
Visit Biff's Septic & Portable Toilet Service →
Biff's earns its place here primarily because of two things: its 24/7 emergency septic service — clearly promoted on the site, not buried in fine print — and its explicit coverage of Winnipeg's suburban ring communities. If you're in West St. Paul, East St. Paul, Headingley, or anywhere else just outside the Perimeter, Biff's is one of the few providers that names your community by name. Their service lineup covers septic tank cleaning, system inspections, and grease trap cleaning — a solid core offering for both residential and small commercial properties.
Pros
- ✓ 24/7 emergency septic service — clearly listed, not just implied
- ✓ Explicit coverage of Winnipeg's suburban and perimeter communities
- ✓ Core lineup covers cleaning, inspections, and grease trap services
- ✓ Registered on Manitoba's provincial sewage hauler list
Cons
- ✗ Registered business is based in Stonewall — not within Winnipeg proper
- ✗ Brand is split between septic services and portable toilet rentals — not a dedicated septic specialist
- ✗ Smaller company; may have limited availability during peak spring season
Best for: Homeowners in Winnipeg's suburban ring — Headingley, the St. Pauls, Rosser, Stonewall — who need 24/7 emergency access or scheduled septic maintenance without driving to the city.
4. Pump-Tech Plumbing & Pump Repair
Experience: 20+ years | Location: Lockport, MB (serves Winnipeg and rural Manitoba)
Manitoba Hauler List: Yes | Certification: Manitoba Conservation certified
Visit Pump-Tech Plumbing & Pump Repair →
Pump-Tech stands out as the most full-system option on this list. While most septic companies focus on pump-outs, Pump-Tech explicitly covers inspections, maintenance, repairs, upgrades, and complete system installations — making them the right call for properties that need more than a routine service appointment. Their Manitoba Conservation certification signals a higher regulatory standard than basic provincial licensing alone. With 20+ years serving homes, farms, businesses, and cottages across Winnipeg and rural Manitoba, they have the range to handle both city-adjacent and remote properties.
Pros
- ✓ Full system capability: inspections, repairs, upgrades, and complete installations
- ✓ Manitoba Conservation certified — above-average regulatory standard
- ✓ 20+ years experience across homes, farms, businesses, and cottages
- ✓ Serves both Winnipeg-area and rural Manitoba properties
Cons
- ✗ Based in Lockport — north of the city; south Winnipeg response times may be longer
- ✗ Emergency service is available on request rather than prominently advertised as 24/7
- ✗ Also covers water, sewage, pump, and lift-station work — not a septic-only firm
Best for: Property owners who need more than a pump-out — new system installations, system upgrades, or complex repairs — especially on farms, rural properties, and new builds outside the city sewer grid.
5. Gotta Go Septic Services
In Business: 22 years | BBB Rating: A+ Accredited | Location: Grande Pointe, MB (serves south Winnipeg)
Manitoba Hauler List: Yes (registered as Gotta Go Portable Toilets)
Visit Gotta Go Septic Services →
Gotta Go rounds out the list as a legitimate local option, particularly for south Winnipeg homeowners. The company has been in business for 22 years and holds a BBB A+ rating — one of only two companies on this list with that credential. Their septic page focuses on pumping services for the south end of Winnipeg, and their spot on Manitoba's registered sewage hauler list confirms provincial compliance. That said, their public-facing septic information is thinner than the top four, with less detail on inspections, repairs, or installations.
Pros
- ✓ BBB A+ Accredited — strong third-party trust signal
- ✓ 22 years in business — well-established local operator
- ✓ Good fit for south-end Winnipeg residential pump-outs
- ✓ Registered on Manitoba's provincial sewage hauler list
Cons
- ✗ Septic service page is short — less public detail than competitors on inspections, repairs, or installations
- ✗ Primarily positioned as a portable toilet company; septic is a secondary offering
- ✗ No mention of 24/7 emergency septic service on their site
Best for: South Winnipeg homeowners who want a BBB-verified, locally established company for routine septic pump-outs.
Does Your Septic Company Need to Be Licensed in Manitoba?
Yes. In Manitoba, any company that pumps and transports sewage must be registered as a sewage hauler with the province under The Environment Act. This registration is publicly searchable, which is why we cross-referenced every company above against Manitoba's registered hauler list. If a company isn't on that list, they are not legally permitted to haul and dispose of septic waste in the province — full stop.
When you're getting quotes, you can ask any septic company directly for their Manitoba sewage hauler registration number. A legitimate operator will provide it without hesitation.
How Often Should You Pump Your Septic Tank in Winnipeg?
The general rule across Manitoba is every 3 to 5 years for a standard residential tank, though the right interval depends on tank size, household size, and daily water use. Winnipeg's cold winters can stress septic systems — frost-heave, frozen inlet pipes, and sluggish bacterial action in cold soil are all real concerns that make regular maintenance more important here than in milder climates.
Signs you shouldn't wait for your next scheduled pump-out:
- Slow drains throughout the house (not just one fixture)
- Gurgling sounds in pipes
- Sewage odour inside or near the tank in the yard
- Unusually green or wet patches of grass over the drain field
- Sewage backup in the lowest fixtures of your home
Any of these symptoms warrant a call to a licensed Winnipeg septic company right away — not a wait-and-see approach.
Which Winnipeg Septic Company Should You Call?
For most Winnipeg homeowners, King's Services is the best starting point — 40 years in the market, a BBB A+ accreditation, a full service range, and a track record on both emergency and scheduled work. If you need a company geared specifically toward commercial and industrial multi-service contracts — septic alongside grease traps and liquid waste — A-1 Environmental Services is the clear choice. For properties in the perimeter communities around Winnipeg, Biff's Septic offers the most explicit coverage and the only advertised 24/7 emergency line. And if you need a full system installed or upgraded rather than just pumped, Pump-Tech Plumbing is the most capable option on the list.
