The Basics
What Are Exhauster Services?
Exhauster services refer to the professional emptying, cleaning and maintenance of septic tanks, soak pits and other wastewater containment systems. Using specialised vacuum tanker trucks, technicians pump out accumulated sludge and effluent and transport it to approved disposal or treatment facilities.
In Nairobi, the high density of estates, commercial buildings and institutions on on-site sanitation means these services are needed regularly. Without timely emptying, septic systems can overflow, causing environmental contamination, foul odours, health risks and costly structural damage.
“A well-maintained septic system is the foundation of a healthy and hygienic property. Regular exhausting and cleaning should not be treated as a luxury but as an essential part of property management.”

What We Do
7 Key Services and Activities
Professional providers do far more than simple tank emptying. Understanding these services helps you decide the type and frequency of maintenance you need.
Service 1
1. Septic Tank Emptying and Draining
This is the core service. A vacuum tanker truck connects its hose to the septic tank access point and suctions out all accumulated sludge, scum and liquid waste. Tanks serviced range from small household units of 500 litres to commercial installations exceeding 20,000 litres. Residential tanks typically need emptying every one to three years, depending on tank size, number of users and waste accumulation.
Service 2
2. High-Pressure Drain Jetting
After emptying, technicians often use high-pressure water jetting to clean the tank walls and drain pipes. This removes stubborn biofilm, grease deposits and encrusted solids that pumping cannot dislodge, and it clears blocked drainage lines throughout a property.
Service 3
3. Septic System Inspection
A thorough inspection checks inlet and outlet baffles, the condition of the tank walls and lid, the state of the drain field or soak pit, and signs of structural compromise or groundwater contamination. Many providers issue a written report, valuable for owners, buyers and health authorities.
Service 4
4. Bio-Treatment and Odour Control
After exhausting, technicians may apply biological enzyme treatments or bacterial activators. These introduce beneficial microorganisms that speed up the breakdown of organic waste, extend intervals between exhausting sessions and reduce odours.
Service 5
5. Grease Trap Cleaning
Restaurants, hotels, schools and other food-handling facilities use grease traps to keep fats, oils and grease out of the main drainage system. Regular cleaning prevents blockages, pest infestations and compliance failures with environmental regulations.
Service 6
6. Drain Unblocking and Root Removal
Technicians use mechanical augers, flexible drain rods and high-pressure jetting to remove blockages caused by grease, hair, soap, foreign objects or invasive tree roots. Prompt unblocking prevents sewage backup and structural damage to pipework.
Service 7
7. Soak Pit Rehabilitation
Soak pits clog over time from excess solids, root intrusion or soil saturation. Rehabilitation involves emptying, inspection, and sometimes excavation and reconstruction of the pit or its perforated lining to restore absorption capacity.
“Many property owners only think about their septic systems when something goes wrong. Proactive maintenance through regular exhausting and inspection is far less expensive than emergency call-outs and repairs.”

Timing
How Often Should You Use Exhauster Services?
Frequency depends on tank size, number of users, whether a garbage disposal unit is connected, and the age of the system.
Household
A tank serving a family of four should generally be pumped every two to three years.
Commercial and institutional
Higher-usage systems may need servicing every three to six months.
Signs you need exhausting immediately:
Sign 1
Slow drains
Slow-draining sinks and toilets
Sign 2
Gurgling
Gurgling sounds in the drainage system
Sign 3
Foul odours
Smells indoors or around the drain field
Sign 4

Safety & Law
Why Professional Services Matter
Managing septic waste without professional equipment and expertise poses serious health, safety and legal risks. Human sewage sludge contains pathogens including bacteria, viruses and parasites. Improper disposal of waste removed from a tank is a public health offence under Kenyan environmental regulations, including the Water Act and the Environmental Management and Coordination Act (EMCA).
Certified providers are authorised to transport and dispose of waste at approved treatment sites, ensuring legal compliance and minimising environmental harm.
“Hiring a certified and experienced exhauster service provider is not just about convenience. It is about protecting your family, your neighbours, and the environment from the serious risks posed by improperly managed sewage waste.”
