Drainage & Sewer Pipe Installation Risk Assessment — Generated Instantly for £29
Describe the drainage or sewer job — trench depth, pipe material, confined space entry, existing services. We generate a fully written, UK-compliant risk assessment covering excavation, lifting, confined space and gas risk in minutes.
Used by groundworkers, drainage contractors and civil engineering firms across the UK
🚧 Entering a manhole, chamber or existing sewer run? Mention it — we will include confined space entry controls, gas monitoring and rescue arrangements required under the Confined Spaces Regulations 1997.
Legal requirements for drainage and sewer pipe installation
Trench excavation for drainage and sewer pipe laying is covered by the Construction (Design and Management) Regulations 2015 (CDM 2015), which require a risk assessment addressing excavation collapse, buried services and site traffic. HSE guidance records that trench collapse remains a recurring cause of serious and fatal injury on groundworks and drainage sites, and that unsupported excavations over 1.2 metres deep present a significant risk without adequate shoring or battering.
Where work requires entry into manholes, chambers or live sewer sections, the Confined Spaces Regulations 1997 apply. Regulation 4 prohibits entry into a confined space unless it is not reasonably practicable to achieve the work without entry, and requires a safe system of work including atmospheric testing, ventilation and emergency rescue arrangements. Sewer atmospheres can contain hydrogen sulphide, methane and reduced oxygen levels, all of which must be assessed and controlled under the Control of Substances Hazardous to Health Regulations 2002 (COSHH).
Manual handling of HDPE pipe sections and lifting operations using excavators or pipe layers fall under the Manual Handling Operations Regulations 1992 and the Lifting Operations and Lifting Equipment Regulations 1998 (LOLER). The overarching duty to carry out and record a suitable and sufficient risk assessment comes from the Management of Health and Safety at Work Regulations 1999, and is expected by principal contractors, water authorities and site managers before works begin.
How it works
1. Describe the job
Tell us the trench depth, pipe material and diameter, whether confined space entry is required, and whether existing underground services are present. Mention lifting methods and backfill requirements too.
2. Let the app take the strain
Anyrisks produces a fully written, UK-compliant risk assessment referencing CDM 2015, the Confined Spaces Regulations 1997 and COSHH 2002 where relevant to your job.
3. Instant download and use
Download as PDF and Word. Hand it to your principal contractor, site manager or water authority, or file it for compliance purposes. £29, no subscription.
What it covers
Every drainage and sewer pipe installation risk assessment is written in full — covering excavation, pipe handling, confined space and gas hazards relevant to your job.
Trench excavation collapse — shoring, battering and trench boxes
HDPE and clay pipe handling and lifting procedures
Manual handling of pipe sections, bedding and jointing materials
Confined space entry into manholes and inspection chambers
Sewer gas risk — hydrogen sulphide, methane and oxygen deficiency
Atmospheric testing and gas monitoring equipment
Existing underground services — cable avoidance and CAT scanning
Mechanical lifting with excavators, pipe layers and LOLER compliance
Backfilling and compaction plant hazards
Trench edge protection and exclusion zones
Working near or over live sewer flows
Vehicle and plant movement on site
Weather and ground condition hazards (waterlogging, flooding)
Emergency rescue arrangements for confined space working
Works for
From new-build drainage runs to emergency sewer repairs, Anyrisks covers every type of drainage and sewer pipe installation work.
What customers say
"We lay a lot of foul sewer connections on new-build sites. Anyrisks covered the trench shoring, pipe lifting and confined space entry all in one document — exactly what the principal contractor wanted."
Dave R.
Drainage contractor, Yorkshire
"Manhole entry was the sticking point with our client's health and safety team. The assessment referenced the Confined Spaces Regulations directly and got us signed off straight away."
Karen M.
Civil engineering site manager, North West
"We handle HDPE pipe lifting with an excavator most days. Having the LOLER and manual handling points already written out saves me an hour every time we start a new job."
Owen T.
Groundworks and drainage operative, South Wales

Frequently asked questions
Do I need a specific risk assessment for drainage and sewer pipe installation?
Yes — drainage and sewer works involve distinct hazards from general groundworks, including confined space entry into manholes, sewer gas exposure, and handling of heavy HDPE pipe sections. Regulation 3(1) of the Management of Health and Safety at Work Regulations 1999 requires a suitable and sufficient risk assessment covering these specific activities, not a generic excavation document.
Does this cover trench excavation for pipe laying?
Yes — describe the trench depth, ground conditions and support method (battered sides, trench box, shoring) and the assessment will include excavation collapse controls under the Construction (Design and Management) Regulations 2015, alongside pipe-specific hazards such as bedding material handling and pipe jointing.
Is confined space entry into manholes and chambers covered?
Yes — entry into manholes, inspection chambers or existing sewer runs is treated as confined space work under the Confined Spaces Regulations 1997. Mention any below-ground entry and the assessment will include atmospheric testing, gas monitoring, ventilation, and rescue arrangements.
Does it address sewer gas and hydrogen sulphide risk?
Yes — where work involves connecting to or entering live sewers, the assessment covers the risk of hydrogen sulphide, methane and oxygen deficiency, with controls referencing COSHH 2002 for exposure to hazardous substances and gas detection equipment requirements.
Can it cover lifting and handling of HDPE pipe sections?
Yes — describe the pipe diameter, length and lifting method (manual, excavator, pipe layer attachment) and the assessment will include manual handling controls under the Manual Handling Operations Regulations 1992 and lifting operation controls under LOLER 1998 where mechanical lifting is used.
Does it cover existing underground services?
Yes — striking existing gas, water, electricity or telecoms services during excavation is one of the most common causes of serious incidents on drainage works. The assessment includes service location (CAT scanning, utility plans), safe digging practices and emergency procedures for service strikes.
Is backfilling and reinstatement included?
Yes — mention the backfill material and compaction method and the assessment will cover trench reinstatement, compaction plant hazards, and surface reinstatement requirements, particularly where works are on a highway or public area.
How long does it take to generate?
Under 2 minutes. Describe the drainage or sewer installation job — trench depth, pipe type, confined space entry and existing services — and Anyrisks produces a complete, regulation-referenced risk assessment instantly, ready to download as PDF and Word.
