Drain problems start below the floor.
Odours, pests, bacteria and biofilm all begin in the drain. Drain Sentinel finds the drains at risk, seals and treats them, and keeps them that way on a schedule, so your team never has to.

Four complaints. One source.
Odours, pests, bacteria and biofilm are usually handled as four separate problems. They start in the same place: the drain, and the pipework beneath it.
01
Odours and sewer gases
A drain that is rarely used dries out. Once the water in the trap evaporates, sewer gas has an open path from the pipework into the room.
Drain sealing and installation
02
Pest activity
Drain flies and cockroaches breed in the film inside the pipe and use the opening as a doorway into the building. Spraying the room treats the wrong end.
Sealing, treatment and servicing
03
Potential bacterial spread
Drains carry a dense bacterial load. Splashing, backups and air moving through a dry trap can carry it to the surface as droplets and aerosols.
Site drain assessment
04
Biofilm and organic buildup
Grease, soap and food residue bind into a film that coats the pipe. It feeds pests, produces the odour and narrows the pipe until it blocks.
Biological wastewater treatmentOne managed program. Every drain covered.
Four core services delivered as a program rather than a callout. We find the drains at risk, seal the ones that should be sealed, treat the pipework and come back on a schedule.
All services in detail
Site drain assessment
Identify high-risk, low-use and target drains on site, then develop a practical management plan for your property.
Biological wastewater treatment
Target biofilm, grease and organic buildup throughout the drainage network using professional wastewater treatments.
Drain sealing and installation
Supply and install waterless trap-seal units to contain odours, sewer gases, pests and contaminants within the drainage system.
Scheduled preventative servicing
Routine treatment, inspections and product maintenance managed by our team to support consistent performance.
Grease trap treatment Add-on
Ongoing treatment that controls odours and organic buildup between pump-outs, for kitchens and food-service sites.
Fewer callouts. Cleaner air. A hygiene record you can show.
Improved drainage hygiene, stronger integrated pest management outcomes and greater operational efficiency through HACCP-verified methods, reducing odours, pest activity, biofilm buildup and reactive maintenance callouts.
Odours contained
Sewer gas stays in the drainage system instead of the dining room, ward or corridor.
Pest pressure cut at the source
Drains stop working as a breeding ground and an entry point, which makes the rest of your pest program work.
Audit-ready records
Every visit, treatment and inspection is documented, so drain hygiene is evidence rather than a line in a checklist.
No workload for your team
No stock to manage, no reminders to set. Scheduling, product and reporting are handled by us.
Assess, seal, treat, maintain.
Assess
We walk the site, map every drain and grade each one by use, risk and location. You get a written management plan.
Seal
Low-use and high-risk drains get waterless trap seals, fitted in minutes with no plumbing works.
Treat
Biological treatment goes into the drainage network to digest biofilm, grease and organic buildup along the pipe.
Maintain
Scheduled visits keep seals, treatment and grease traps performing, with a report after every visit.

Protection that does not add to your team's workload.
Reactive drain problems land on whoever is on shift. A managed program takes them off the roster entirely.
- No product to order, store or track. We bring what each visit needs.
- Visits are scheduled around trading hours and access requirements.
- One report per visit, one contact for the whole portfolio.
- Works alongside your existing pest control and cleaning contracts.
Anywhere a drain sits close to people, food or patients.
Hospitality
Hotels, pubs, clubs and venues where a drain smell reaches the guest before it reaches maintenance.
Healthcare
Hospitals, aged care and clinics, where drains near patient care are an infection-control concern.
Commercial
Offices, retail and mixed-use buildings with plant rooms, amenities and loading docks.
Food service
Commercial kitchens, food manufacturing and cold rooms, where grease, biofilm and HACCP audits meet.
Managed facilities
Facility managers and strata portfolios that want one program and one report across many sites.
Residential
Apartment buildings and homes with a persistent drain smell, drain flies or a bathroom that is rarely used.
