Know exactly what's
failing in your sewer line — before it fails you.
CCTV inspection, defect grading and a GIS-mapped condition report for your sewer infrastructure, delivered in 48 hours by NEMA-compliant crews. Serving Nairobi, Mombasa, Kisumu, Nakuru and 50+ Kenyan towns.
Sample defect grading — 6m line segment
Each segment scored 1 (acceptable) to 5 (critical) during CCTV inspection
Why assess now
Five signs your sewer line needs inspection this month
Sewer failures are rarely sudden — they show up as small signals first. Catching them at inspection stage costs a fraction of an emergency dig-up.
Recurring blockages
The same manhole or fixture backs up more than once a quarter, even after clearing.
Persistent odour
Sewer gas smell near drains or compound boundaries usually points to a cracked or displaced joint.
Ground settling or lush patches
Sunken ground or unusually green grass along the pipe run signals leakage or root intrusion.
Aging infrastructure
Clay or unlined concrete lines over 20 years old are past due for a structural condition check.
Pre-purchase or lease due diligence
Buying, leasing or refinancing a property? A condition report protects you before the contract, not after.
Planned development nearby
Construction or excavation adjacent to a sewer line warrants a baseline inspection to document existing condition.
How the assessment runs
From site visit to remediation plan in five stages
Every assessment follows the same fixed sequence, so nothing gets skipped and every report is comparable to the last.
Site survey & access mapping
We locate manholes, inspection chambers and cleanouts, and confirm line length and access points before equipment arrives.
CCTV line inspection
A push-rod or crawler camera runs the full length of the line, recording continuous footage with distance and orientation logged at every meter.
Defect coding & condition grading
Every structural and service defect — cracks, root intrusion, deformation, blockage, joint displacement — is coded and scored 1 to 5 by segment.
GIS-mapped condition report
Findings are compiled into a report with a segment-by-segment map, footage timestamps, photos and a plain-language summary.
Remediation roadmap
Critical segments are prioritised with recommended fix — spot repair, relining or replacement — and an indicative cost range.
Built for
Who commissions a sewer infrastructure assessment
Estates & property managers
Scheduled condition checks across shared sewer lines to plan maintenance budgets ahead of failure.
Commercial & industrial sites
Factories, malls and hospitality properties documenting line condition for insurance and compliance.
Institutions
Schools, hospitals and campuses assessing aging infrastructure before a capital works cycle.
Counties & developers
Baseline surveys for new developments and county infrastructure audits, with GIS-ready deliverables.
Coverage
Assessment crews dispatched across Kenya
CCTV crawler units and certified assessors operate from regional depots, so site visits are scheduled within 24–48 hours in these areas.
Questions
Sewer assessment, answered directly
How much does a sewer line assessment cost in Kenya?
Cost depends on line length, number of access points, and whether CCTV crawler access is needed. Most single-property assessments in Nairobi start from KES 15,000. Estates, institutions and county contracts are quoted per meter after a site scope call — request a free quote below for an exact figure.
How long does a CCTV sewer inspection take?
A standard residential or commercial line survey takes 2 to 4 hours on site. The full condition report with defect grading and remediation recommendations is delivered within 48 hours.
What is sewer defect grading?
Defect grading scores each pipe segment from 1 (acceptable) to 5 (critical, requiring immediate action) based on structural and service defects observed during CCTV inspection, following WRc-aligned coding standards. It tells you exactly which sections to fix first, rather than guessing.
Do I need a sewer assessment before buying or leasing a property?
Yes. A pre-purchase or pre-lease sewer assessment identifies collapsed sections, root intrusion and blockages before they become your liability — the same due diligence used for a structural survey, applied to the drainage line.
Which areas does Omidrop Africa cover for sewer assessments?
Nairobi, Mombasa, Kisumu, Nakuru, Machakos, Kajiado and over 50 towns nationwide, with certified crews and CCTV crawler units dispatched from regional depots.
