Sanitary sewage pits
Cleaning and decontamination of sewage pits and wet wells. We remove sludge and solids, disinfect the structure and restore safe, odour-controlled operation.

Industrial Services
Industrial cleaning, inspection, waste management and operational services, delivered on site.
Overview
Industrial cleaning, inspection, waste management and operational services, delivered on site.
We clean and decontaminate sewage and industrial wastewater pits and oil exploration sites, inspect sewer lines by CCTV, and collect, transport, treat and recycle waste and wastewater. Every job is planned around confined-space safety and documented waste handling.
01Cleaning, decontamination and inspection
Every job is planned around confined-space safety and documented waste handling.
Industrial wastewater pits
Cleaning and decontamination of pits that receive process effluent. Oily, chemical and solid residues are removed and handled according to their hazard class.
Oil exploration sites
Cleaning and decontamination of drilling and exploration site pits and work areas, including oily sludge and drilling residues, for a safe handover.
CCTV sewer inspection
Camera inspection of sewer lines to locate blockages, cracks, leaks and misconnections. Findings are recorded to guide repair and maintenance plans.
02Cleaning sanitary sewage pits
Collected waste goes to approved disposal points, with documented handling for every load.
- Secure the site and test the airWe cordon off the work area, set up confined-space controls and test for toxic and flammable gases before entry.
- Pump out liquids and sludgeVacuum tankers remove wastewater, sludge and solids from the pit. Everything is contained and recorded.
- Wash down the pitTrained crews clean walls, floor and pipework with high-pressure jetting until all residues are removed.
- Disinfect and hand overWe disinfect the structure, control odours, inspect the result and issue a completion report.
03Cleaning industrial wastewater pits
Hazardous residues are handled and transported under approved procedures, and documented for every load.
- Sample and classify the wasteWe sample the pit contents and analyse them to identify hazards and choose the right method and protection.
- Isolate and ventilateConnected lines are isolated and locked out, the pit is ventilated and gas levels are monitored throughout.
- Remove and cleanVacuum and high-pressure equipment remove sludge, oily and chemical residues from the pit and pipework.
- Decontaminate and disposeWe decontaminate surfaces, verify the result and send each waste type to an approved facility with records.
04Waste and wastewater logistics
Waste transport
All waste classes. Safe collection and transport of hazardous and non-hazardous waste, with the right vehicles, documentation and disposal route for each waste class.
Waste recycling
Multiple waste streams. Sorting, treatment and recovery of different waste streams into reusable materials and energy, reducing what goes to landfill.
Sanitary wastewater logistics
Transport management. Planning, scheduling and tracking of sewage tanker movements from the source to approved treatment or disposal points.
Industrial wastewater logistics
Transport management. Managed transport of industrial effluent, matched to its characteristics and routed to approved facilities, with records for every load.
How every load moves

Common questions
Is confined-space work done safely?
Yes. Every job starts with a site set-up, isolation where needed and gas testing before entry, and gas levels are monitored throughout the work.
Where does the collected waste go?
To approved treatment, recycling or disposal points that suit its class, with documented handling for every load.
Do you provide records after the job?
Yes. You receive a completion report and the waste handling records for the loads removed from your site.
