Exhauster services are essential for removing accumulated sludge, sewage, and wastewater from septic tanks, grease traps, pit latrines, and industrial holding tanks. Our high-capacity exhauster trucks safely extract waste using industrial vacuum technology, minimising health risks and preventing overflow, contamination, or structural damage to your waste system.
The Nairobi metropolitan area generates millions of litres of wastewater daily. Most septic systems are on informal or missed maintenance schedules. The consequences of deferred siphoning range from offensive odours and blocked drains to full septic overflow — a public health event.

We offer comprehensive waste management solutions tailored to residential, commercial, and industrial properties:
Scheduled siphoning for household septic tanks (1,000–5,000L) with minimal site disruption.
High-frequency siphoning for hospitality properties with large-volume tanks. Timed to low-occupancy periods.
High-volume industrial vacuum trucks for factories and processing plants with multiple waste holding systems.
Specialist grease trap extraction and jetting for restaurant and industrial kitchens. Prevents sewer blockages.
Same-day emergency dispatch for overflowing septic tanks and blocked systems. 2-hour response in Nairobi.
Scheduled siphoning of portable toilets, site welfare tanks, and temporary holding pits for construction projects.
Our matched exhauster fleet covers all property types and tank sizes across Kenya:

Overflowing septic tanks cannot wait. Our emergency exhauster teams are deployed across Nairobi, Mombasa, Kisumu and 47+ towns, arriving with industrial vacuum trucks within 2 hours in urban areas.
Septic overflow is a health hazard, a liability, and a NEMA violation. Our operations line is staffed 24 hours, 365 days — including holidays.

OmiDrop Africa operates exhauster and siphoning services across Kenya's major urban and peri-urban centres with real truck capacity:
Most septic tanks should be emptied every 2–3 years, depending on household size, tank capacity, and usage. Larger households or smaller tanks may need more frequent emptying. If you notice slow drains, bad smells, or waterlogging near the tank, book a service immediately.
Sludge is the layer of solid waste that settles at the bottom of your septic tank over time. As it accumulates, it reduces the tank's effective capacity and can cause blockages or overflow. Regular exhauster services remove this sludge and restore your tank's function.
