Sewer Line Unblocking
& Drain Cleaning
Kenya
Blocked drain? Sewage backup? Slow-running system? Maji Hill dispatches trained drain teams across Kenya within 2 hours for emergency response — high-pressure jetting, mechanical rodding, CCTV inspection, root cutting, grease trap cleaning, and gully emptying. We clear the blockage, find the cause, and fix it permanently. Available 24 / 7.
WHY KENYAN PROPERTIES NEED A PROFESSIONAL DRAIN TEAM
A blocked sewer is not just an inconvenience — it is a public health emergency, a business disruption, and a property risk. Raw sewage backing up into a building, overflowing manholes, and blocked grease traps can close a restaurant, render a hotel wing unusable, and expose property managers to regulatory action. Maji Hill provides the trained teams, professional equipment, and documented service that the problem demands.
2-Hour Emergency Response, 24 / 7
A sewage overflow cannot wait until morning. Maji Hill dispatches emergency drain teams within 2 hours across most of Kenya’s towns and urban areas — 24 hours a day, every day including weekends and public holidays. We confirm dispatch by WhatsApp with the team’s name and estimated arrival time.
Equipment That Actually Clears the Blockage
Many drain operators in Kenya use manual rodding that moves the blockage rather than clearing it. Maji Hill uses high-pressure water jetting up to 200 bar — the only method that reliably cuts through compacted grease, dislodges root masses, cleans pipe walls, and prevents immediate re-blockage. We bring the right equipment to every job, not just a rod.
We Find the Cause, Not Just Clear the Block
Treating only the symptom — clearing a blockage without finding why it occurred — leads to repeat blockages at 2-week intervals. Maji Hill investigates the cause of every blockage. Where the cause is structural (root intrusion, collapsed pipe, misaligned joint), we diagnose it with CCTV and give you a permanent repair option — not just a recurring call-out.
All Property Types and Drain Sizes
From a blocked kitchen sink in a Nairobi apartment to a major sewer main serving a hotel complex in Mombasa — our equipment range covers drain diameters from 50 mm domestic waste pipes to 600 mm sewer mains. We work on residential, commercial, institutional, and industrial drainage systems across Kenya.
Documented Service with Job Report
Every Maji Hill drain cleaning visit is completed with a written job report covering the blockage location, cause, method used, volume cleared, CCTV findings where applicable, and any structural defects observed. This report supports insurance claims, maintenance records, NEMA compliance documentation, and property management accountability.
Scheduled Maintenance Contracts
Reactive drain cleaning is always more expensive than prevention. For hotels, restaurants, schools, hospitals, and commercial estates, Maji Hill offers scheduled drain maintenance contracts — regular jetting of high-risk lines, grease trap pump-out at agreed intervals, and annual CCTV surveys — eliminating emergency call-outs and keeping drainage systems running reliably year-round.

DRAIN UNBLOCKING AND CLEANING METHODS WE USE ACROSS KENYA
Maji Hill selects the right method — or combination of methods — for each blockage type and pipe configuration. We never use the same tool for every job.
High-Pressure Water Jetting — Up to 200 Bar
High-pressure water jetting is the most effective method for clearing grease accumulation, compacted silt, root fragments, and scale from drain and sewer lines of all sizes. Water is propelled at up to 200 bar through a flexible hose with a specialist nozzle that simultaneously jets rearward (propelling the hose forward) and forward (cutting through the blockage). Pulling the hose back while jetting cleans the pipe wall completely — not just creating a channel through the blockage. We carry jetting units sized for 50 mm domestic pipes through to 600 mm sewer mains, and our hose lengths reach blockages up to 120 metres from the access point. Jetting is always combined with downstream collection at a manhole to prevent cleared debris from causing a secondary blockage.
CCTV Drain Inspection — Camera Survey
A CCTV drain survey is the only accurate way to diagnose the internal condition of a drain — seeing root intrusion, collapsed sections, displaced joints, cracked pipes, and the nature and location of a blockage precisely. We use self-propelled camera crawlers for sewer mains (150 mm and above) and push-rod cameras for smaller domestic and commercial drains. All footage is recorded with GPS referencing and timestamped defect logging. A written condition report is produced from every CCTV survey, referencing defect locations to standard drainage defect coding. CCTV is recommended after every significant blockage to confirm the pipe is clear and to identify whether structural repairs are needed to prevent recurrence.
Root Cutting and Intrusion Removal
Root intrusion is one of the most common causes of repeat blockages in older drainage systems across Kenya, where clay and concrete pipes with open joints allow tree and shrub roots to enter and grow progressively until they cause a full or partial blockage. We remove root masses using high-pressure jetting with a root-cutting nozzle for soft root material, and a mechanical root cutter (chain flail or blade cutter driven by a flexible drive shaft) for established root masses in larger pipes. Root cutting is always followed by a CCTV inspection to confirm the pipe is clear and to assess whether the joint allowing root entry requires a structural repair — such as a patch liner — to prevent re-growth.
Grease Trap Cleaning and FOG Management
Grease traps in Kenyan hotels, restaurants, school canteens, and food processing facilities capture fats, oils, and grease (FOG) before they enter the drainage system — but only if they are cleaned at the correct frequency. A grease trap that exceeds 25% of its capacity in accumulated fat will begin passing grease into the drain system, causing downstream blockages that are significantly more costly to clear than a routine pump-out. Maji Hill carries out grease trap pump-out, full clean of the trap chamber, inspection of inlet and outlet baffles, check of the trap capacity against current kitchen output, and a service certificate. For high-volume catering operations we offer weekly, fortnightly, and monthly scheduled service contracts.
Mechanical Rodding for Localised Blockages
Mechanical drain rodding uses rigid fibreglass rods connected in sections to apply rotational and pushing force directly to a blockage — effective for localised soft blockages in domestic waste pipes where the access point is close to the obstruction. Rodding is faster to set up than jetting for straightforward blockages and is used as the first response tool for simple household drain blocks. Where rodding fails to clear a blockage completely — or where the blockage is beyond the reach of the rod set — we escalate to high-pressure jetting. Rodding alone does not clean pipe walls and is not an alternative to jetting for grease-accumulated or root-blocked lines.
Gully Emptying and Silt Trap Cleaning
Surface water gullies, yard gullies, silt traps, and interceptor chambers accumulate silt, grit, leaf debris, and sediment that — if not regularly cleared — back up into surrounding hard surfaces, contribute to downstream sewer surcharging, and in industrial settings can cause NEMA effluent compliance failures. We clean gullies using combination jetter-sucker units that simultaneously jet the chamber and suction out the dislodged material — clean, efficient, and leaving no debris on the surrounding surface. Silt trap and interceptor cleaning is carried out with full waste manifesting for regulatory compliance.
8 SIGNS YOUR DRAIN OR SEWER NEEDS URGENT ATTENTION
Most sewer and drain failures give early warning. Recognising these signs and acting immediately prevents a minor blockage from becoming a major sewage overflow or structural drain failure.
Sewage Backing Up into Toilets or Showers
Raw sewage appearing in fixtures — particularly in ground-floor toilets or floor drains — is a complete main sewer blockage. This is a public health emergency requiring immediate response. Call Maji Hill now on +254 710 573 334.
Sewage Overflowing from Manholes
An overflowing manhole indicates the sewer is completely blocked or surcharging downstream. It is both a public health hazard and a NEMA compliance issue. It requires same-day emergency response — not a scheduled visit.
Multiple Slow-Draining Fixtures Simultaneously
When several fixtures across the property drain slowly at the same time — toilets, showers, sinks — the blockage is in the main sewer line rather than an individual branch. This is a developing full blockage and needs professional jetting before it becomes a complete overflow.
Gurgling Sounds When Draining
Gurgling or bubbling from drain outlets when a toilet is flushed or a bath drains indicates air being displaced from a partially blocked line. It is an early warning of an imminent full blockage — addressing it now costs significantly less than an emergency call-out when the blockage is complete.
Persistent Sewage Smell Inside or Outside
A sewage odour inside the property — particularly from floor drains or ground-floor fixtures — or around manholes and the soakaway area indicates a partially blocked or backed-up sewer. Odour is also caused by dry or broken p-traps, but recurring smell with no obvious trap cause points to a main line issue.
Drain Blocks Frequently and Repeatedly
A drain that blocks every few weeks despite regular clearing is almost always a structural problem — root intrusion, a displaced joint creating a low spot, a partially collapsed section, or a pipe that has been incorrectly graded. Repeated rodding treats the symptom; a CCTV survey finds the cause.
Grease Trap Overflowing or Smelling Strongly
A grease trap that is visibly full, overflowing into the surrounding area, or emitting a strong rancid odour is already passing grease into the downstream drainage system. Immediate pump-out is required to stop the FOG loading on the sewer and prevent a full drain blockage in the kitchen drainage line.
Wet Patches or Lush Vegetation Over the Drain Route
A saturated area of ground or a strip of unusually lush grass following the route of an underground drain indicates a drain fracture or an open joint through which sewage is escaping into the surrounding soil. This is both a structural failure and a ground contamination issue requiring prompt CCTV investigation and repair.

WHAT CLIENTS ACROSS KENYA SAY ABOUT MAJI HILL DRAIN SERVICES
Feedback from homeowners, hotel managers, and facilities teams whose drainage emergencies and planned maintenance Maji Hill has handled across Kenya.
“Sewage backed up into our ground-floor bathrooms at 9 PM on a Friday. I called Maji Hill and their team was on site within 90 minutes. They jetted the main sewer, cleared a massive grease and root blockage about 40 metres from the building, then did a quick CCTV run to confirm the pipe was clear. Written report in hand before midnight. Absolutely professional under pressure — exactly what you need in a crisis.”
“Our restaurant kitchen drain had blocked three times in two months. Previous contractors just rodded it and left. Maji Hill came with a jetter and a push camera. They cleared it completely with high-pressure jetting, then showed us on the camera footage exactly where the grease trap outlet was compromised and fat was building in the line. They fixed the outlet baffle, recommended a fortnightly grease trap schedule, and we haven’t had a block since. That’s the difference between a repair and a solution.”
“We manage a school in Mombasa with 800 students and an ageing drainage system. Maji Hill did a full CCTV survey of all our sewer lines during the school holidays, produced a condition report with footage, and identified four sections with root intrusion that needed cutting before the next term. They cleared all four zones and put us on a termly maintenance contract. No drain emergencies since. Every school should do this.”

What causes a sewer line to block in Kenya?
The most common causes of sewer blockages in Kenyan properties are fat, oil, and grease accumulation from kitchen waste — by far the most common cause in hotels, restaurants, and domestic kitchens; root intrusion from trees growing into joints in older clay or concrete pipes; accumulation of non-flushable items including wipes, sanitary products, and rags; collapsed or displaced pipe sections in old or poorly bedded drainage; soap scum and hair build-up in bathroom drainage; and silt accumulation in flat or under-graded sewer lines. Grease accumulation and root intrusion account for the majority of repeat blockages in commercial properties, and both require high-pressure jetting and a structural assessment to solve permanently.
What is high-pressure drain jetting and how does it work?
High-pressure water jetting propels water through a flexible hose at pressures between 80 and 200 bar — powerful enough to cut through accumulated grease, break up root masses, and thoroughly clean pipe walls up to 600 mm in diameter. The jetting nozzle simultaneously jets rearward (propelling the hose forward into the pipe) and forward (cutting through the blockage). Pulling the hose back while jetting cleans the full pipe wall rather than just creating a channel through the obstruction — which is why jetting is significantly more effective at preventing re-blockage than manual rodding. We collect the dislodged debris at a downstream manhole to prevent secondary blockages forming further in the system.
What is a CCTV drain survey and when do I need one?
A CCTV drain survey uses a camera — either a self-propelled crawler for larger sewer mains or a push-rod camera for smaller pipes — to inspect the interior of drainage pipes, producing a recorded video of the pipe condition. It is the only accurate way to see root intrusion, collapsed sections, displaced joints, cracked pipes, and the exact location and nature of a blockage. A CCTV survey is strongly recommended after any significant blockage to confirm the pipe is fully clear and to check whether a structural defect is causing the problem. It is also standard practice before purchasing a property with older drainage, before any major building or extension work, and when a drain is recurring-blocking despite regular clearing.
How often should commercial grease traps be cleaned in Kenya?
Commercial grease traps in Kenyan hotels, restaurants, school canteens, and food processing facilities should be cleaned at minimum monthly — and in high-volume operations, weekly or fortnightly cleaning is often necessary to keep grease levels below 25% of trap capacity. Once a grease trap exceeds 25% full, it begins allowing grease to bypass into the drain system downstream, causing blockages that are far more expensive and disruptive to clear than a scheduled pump-out. The correct interval depends on daily meal volume, food type, and trap size. Maji Hill offers grease trap maintenance contracts with fixed-frequency service visits, a service certificate after each pump-out, and a capacity-to-output review at the initial visit to confirm the correct cleaning frequency for your kitchen’s actual output.
My drain has been blocked three times this month. What is causing it?
A drain that blocks repeatedly despite regular clearing almost always has a structural cause — not just a usage issue. The most common structural causes of repeat blockages are root intrusion through open joints in older clay or concrete pipes (roots re-grow rapidly after cutting if the entry joint is not repaired); a displaced or sagging pipe section creating a low spot where solids accumulate; a collapsed section reducing pipe diameter; a misaligned joint creating a ledge that catches debris; and a grease trap that is undersized for the kitchen output, allowing grease breakthrough regardless of cleaning frequency. A CCTV survey after jetting identifies which of these is the cause and allows a permanent repair to be designed and costed — stopping the repeat call-out cycle.
