Unclog Drain & Rooter drainage mapping accuracy depends on using the right technology for each situation. Our engineers are trained across the full range of survey methods and select the appropriate combination for every project.
High-definition waterproof cameras fed through pipe systems via inspection chambers. Unclog Drain & Rooter push-rod cameras cover pipes from 75 mm to 600 mm diameter with real-time HD footage to surface monitors. Crawler cameras are deployed for larger diameter pipes and longer distances, producing footage with distance measurement overlay for accurate defect location mapping and pipe condition coding.
Unclog Drain & Rooter uses ground-level GPS to record the position of every manhole, inspection chamber, and access point to sub-metre accuracy. Combined with sonde transmitters inserted into CCTV cameras, we locate the precise surface position of pipes that have no accessible inspection chambers – generating accurate pipe centerline data for CAD drawing production even where original drainage records do not exist.
For sites where CCTV and sonde tracing cannot locate pipes – such as very deep buried services, pipes below thick concrete slabs, or non-metallic pipes in complex ground – Unclog Drain & Rooter deploys GPR. The radar signal penetrates up to 3 metres below the surface and identifies voids, pipe locations, and buried structures without any excavation. GPR is particularly valuable for confirming drainage routes beneath existing buildings and verifying soakaway positions.
All Unclog Drain & Rooter survey data is processed into professional CAD drainage drawings using AutoCAD and Civil 3D. Drawings are produced to NCC and county planning submission standards – complete with title blocks, north points, scales, dimension strings, pipe schedules, and manhole schedules. Unclog Drain & Rooter drawings are accepted by Nairobi City County, all Kenya county councils, and NEMA without re-drawing.
Unclog Drain & Rooter drainage engineering and mapping services are not just for large infrastructure projects. These are the eight most common situations across Kenya where a professional drainage survey or design is not optional – it is essential.
An Unclog Drain & Rooter pre-purchase drainage survey identifies hidden defects before you commit to a purchase – giving you the documented evidence to negotiate or walk away. Essential for any property transaction in Kenya.
Nairobi City County and Kenya county councils require drainage strategy reports and CAD drainage drawings with planning applications for all new developments. Unclog Drain & Rooter produces NCC-compliant packages that are accepted first time.
Most properties in Kenya have no accurate drainage records. Before extending, excavating, or building on a site, Unclog Drain & Rooter mapping establishes exactly where underground pipes are – preventing accidental damage during construction.
When repeated drain clearing fails to stop recurring blockages, the problem is structural. Unclog Drain & Rooter CCTV condition survey locates and rates every defect, producing the evidence needed to plan targeted permanent repairs.
NEMA inspections increasingly require documented evidence of drainage system condition, connection arrangements, and trade waste management. Unclog Drain & Rooter condition survey reports and drainage drawings satisfy these requirements directly.
When handing over a completed development or assuming management of an existing estate, Unclog Drain & Rooter as-built drainage records and condition surveys establish a baseline for the incoming management team’s maintenance programme.
Insurance assessors require documented evidence of drainage defects and their cause. Unclog Drain & Rooter CCTV reports and drainage drawings are formatted to the evidence standards required by Kenya’s major property insurers.
Property managers and facilities teams need quantified drainage condition data to set accurate maintenance budgets. Unclog Drain & Rooter condition surveys provide a defect register with costed remediation schedules – the foundation of evidence-based infrastructure planning.

Honest answers to the questions developers, architects, and property managers across Kenya ask Unclog Drain & Rooter before commissioning a drainage engineering project.
Drainage system mapping is the process of accurately locating, surveying, and recording all underground drainage pipes, manholes, and connections on a property or site. Most properties across Kenya have no accurate drainage records – original construction drawings are lost, inaccurate, or have never been produced. Unclog Drain & Rooter creates the definitive record using CCTV cameras, GPS survey, and ground-penetrating radar. This map is needed before any building work, excavation, extension, or purchase – and is required for county council planning submissions and NEMA environmental audits.
Unclog Drain & Rooter drainage surveys start from KES 35,000 for a single residential property CCTV condition survey including a CAD as-existing drainage drawing. Estate and commercial site drainage mapping surveys start from KES 95,000. New development drainage design fees are quoted individually based on site area and scope after a free briefing. All fees are fixed-price and confirmed before fieldwork begins. Unclog Drain & Rooter does not charge for initial briefing discussions or indicative fee proposals.
Yes. Unclog Drain & Rooter produces drainage drawings to Nairobi City County and Kenya county council submission standards – including the required title block format, drawing scales, north points, dimension conventions, pipe schedules, manhole schedules, and hydraulic calculation notes. Our drawings are accepted by NCC and all Kenya county councils for building approval and planning applications without requiring re-drawing. We also produce NEMA environmental drainage documentation in the format required for environmental impact assessments and NEMA compliance audits.
Yes – and this is one of the most common scenarios across Kenya. Unclog Drain & Rooter uses three methods to locate pipes with no existing records. First, CCTV push-rod surveys with a sonde transmitter allow the camera position to be detected from the surface and GPS-recorded as it travels through the pipe. Second, drain tracing dye is used to trace connections between fixtures and the main drainage system. Third, ground-penetrating radar (GPR) locates buried pipes up to 3 metres below the surface without any excavation. These methods together allow us to map drainage networks accurately even where no original records exist.
Unclog Drain & Rooter delivers drawings in the formats requested by the client. Standard delivery is PDF at A1 or A3 paper size and AutoCAD DWG file for CAD drawings. For large estate and infrastructure mapping projects, we also provide GIS datasets in Shapefile (SHP), Google Earth KMZ, and AutoCAD Map DWG format with full attribute data. CCTV condition reports are delivered as PDF documents with embedded HD video footage. We can accommodate specific formatting or delivery requirements for clients with their own CAD standards or asset management systems.
Field survey duration depends on site size and access conditions. A single residential property CCTV survey and manhole survey typically takes 3 to 5 hours on site. A medium estate of 20 to 50 units typically takes 2 to 4 days of fieldwork. Drawing production and report writing takes a further 3 to 7 working days after field data is collected and quality-checked. Full project timelines are confirmed at the briefing stage – Unclog Drain & Rooter can accommodate urgent programmes for time-critical planning submissions or property transactions.
Yes. Unclog Drain & Rooter pre-purchase drainage survey reports are specifically formatted to be used in property transactions. The report includes a condition rating for every pipe surveyed, a defect register with repair cost estimates, HD CCTV footage evidence, and an overall drainage system health assessment. This gives buyers documented evidence of drainage defects and quantified repair costs – enabling direct price negotiation or a requirement for the vendor to carry out repairs before completion. The report format is accepted by Kenyan solicitors, mortgage lenders, and property insurers.
