Pipeline Rehabilitation
Safe removal and replacement of asbestos cement pipes in water and sewer networks with complete system restoration. ASBE Contractors Limited specialises in the decommissioning, safe removal, and full replacement of asbestos cement (AC) pipes across water supply and sewerage infrastructure throughout Kenya.
Our pipeline rehabilitation services restore full operational functionality to ageing pipe networks while permanently eliminating the health, environmental, and legal risks associated with deteriorating asbestos cement infrastructure.
Why Pipeline Rehabilitation Matters
Asbestos cement pipes were widely used across Kenya’s water and sewer infrastructure before the dangers of asbestos were fully understood. As these pipes age and deteriorate, the risks escalate significantly:
Asbestos fibres leach into drinking water supplies from cracked or corroded pipes
Broken pipes release fibres directly into surrounding soil and groundwater
Workers excavating or repairing ageing AC pipes face serious inhalation exposure
Deteriorating pipes cause significant water loss, pressure failure, and system breakdown
Deferred replacement creates growing environmental liability and regulatory risk
Non-compliant infrastructure exposes property owners and utilities to NEMA enforcement action
Rehabilitation Process
1. Pipeline Inspection & Survey
Comprehensive inspection and condition mapping of all asbestos cement pipe sections; risk level assessed and removal method selected for each section
2.Area Isolation & Containment
Work zones established with safety barriers, containment sheeting, restricted access, and full dust suppression to prevent public or worker exposure
3. Safe Pipe Removal & Encapsulation
Asbestos cement pipes carefully excavated using wet suppression methods to prevent fibre release; all sections immediately encapsulated on removal
4. Secure Packaging, Labelling & Disposal
Removed pipe sections packaged in NEMA-approved containers, fully documented, and transported to licensed disposal facilities for compliant disposal
5. New Pipe Installation & System Refitting
Modern, compliant replacement pipes installed to current engineering, water quality, and regulatory standards; all connections and joints properly sealed
6. Infrastructure Reinstatement & System Testing
Surrounding infrastructure, trenches, and surfaces restored; pressure testing, flow testing, and water quality verification completed before handover
What's included
Full Pipeline Inspection & Condition Assessment
Comprehensive survey and risk mapping of all asbestos cement pipe sections to establish the full scope of works, prioritise sections for removal, and determine the safest removal methodology for each.
Safe Excavation & Pipe Removal
Careful excavation of all identified asbestos cement pipe sections using wet suppression techniques to control dust and fibre release throughout, with immediate encapsulation of all removed sections on site
Dust Suppression & Continuous Air Monitoring
Wet suppression systems active during all excavation and removal activities, combined with continuous real-time air monitoring to maintain safe fibre levels throughout the work zone and surrounding area.
Certified PPE for All Personnel
Full personal protective equipment provided for every team member involved in removal — powered air-purifying respirators or P3 half-masks, Type 5 protective suits, safety gloves, boots, and eye protection.
NEMA-Compliant Disposal of All Removed Pipes
All removed asbestos cement pipe sections packaged in NEMA-approved rigid containers, fully labelled, transported on licensed hazmat vehicles, and disposed of at authorised hazardous waste facilities.
New Pipe Supply & Professional Installation
Supply and professional installation of modern, fully compliant replacement pipes to current water quality, engineering, and regulatory standards, with all joints, connections, and fittings properly sealed and tested.
Infrastructure Reinstatement & System Testing
Full reinstatement of all excavated areas, trenches, road surfaces, and surrounding infrastructure, followed by comprehensive pressure testing, flow testing, and water quality verification before system handover.
Full Compliance Documentation Package
Complete project records provided to the client including pipeline inspection reports, risk assessments, waste transfer certificates, disposal certificates, reinstatement records, and system test results.
