Commercial Drain Condition Surveys & PPM
Understand the condition of your drainage before defects become failures.
We carry out drainage condition surveys for commercial and industrial sites, helping property managers, facilities teams and asset owners identify defects, plan maintenance and prioritise remedial works.
When should you arrange a commercial drainage condition survey?
Commercial drainage condition surveys are useful when you need to understand the current state of a drainage network, identify developing defects and plan maintenance before problems become disruptive or expensive.
They are commonly carried out when:
Taking responsibility for a new commercial site
Building a planned preventative maintenance programme
Investigating recurring drainage problems
Assessing ageing or poorly documented drainage infrastructure
Planning refurbishment or redevelopment works
Preparing maintenance or capital expenditure budgets
Monitoring known defects over time
Assessing drainage condition before acquisition, lease or handover.
What does a commercial drainage condition survey include?
The scope of a commercial drainage condition survey can be tailored to the size of the site, the drainage network and the level of detail required. Depending on the agreed scope, our surveys can include:
CCTV inspection of accessible foul and surface water drainage
WRc-approved report with MSCC5 coding to identify structural and service defects
Identification of cracks, fractures, displaced joints, root ingress, deposits and restrictions
Recording of pipe diameters, materials and flow direction, where these can be established
Identification and recording of manholes, chambers and key drainage assets
Drainage mapping to help build or update site drainage records
HD CCTV footage and supporting images
Identification of areas requiring cleaning, repair or further investigation
Clear maintenance and remedial recommendations
Recording of any access limitations or sections that could not be surveyed.
For larger sites, the survey can also be phased or prioritised around critical areas of the drainage network, helping facilities and asset teams focus attention where it is most needed.
Condition surveys as part of planned preventive maintenance
A drainage condition survey can form an important part of a wider planned preventive maintenance (PPM) programme by identifying developing issues before they lead to blockages, failures or disruption.
For commercial and multi-building sites, regular CCTV inspections can help facilities and asset teams:
Monitor known defects over time
Identify where cleaning or maintenance is required
Prioritise structural repairs before deterioration worsens
Reduce the risk of unexpected drainage failures
Build a clear record or drainage asset condition
Support maintenance planning and future expenditure
Surveys can be carried out as a one-off assessment or at agreed intervals as part of an ongoing maintenance programme, depending on the size, age and operational importance of the drainage network.
Who are commercial drainage condition surveys for?
Our commercial drainage condition surveys are suitable for organisations that need a clear understanding of drainage condition across a site or property portfolio.
We regularly support:
Facilities management companies
Property and asset managers
Commercial landlords and property owners
Industrial and manufacturing sites
Schools, colleges and healthcare estates
Retail, hospitality and leisure sites
Offices, business parks and multi-building sites
Developers and contractors taking responsibility for existing drainage infrastructure
The scope can be tailored to a single building, individual drainage system or a large multi-asset site, depending on the level of information required.
How does the survey process work?
We keep commercial drainage condition surveys structured and straightforward, with the scope agreed before work begins.
Site information and scope review: We review existing drainage plans, known issues, site constraints and the level of reporting required.
Survey programme agreed: For larger or operational sites, the survey can be phased or prioritised around critical areas to minimise disruption.
CCTV inspection and asset recording: Our engineers inspect the accessible drainage network, recording pipe condition, defects, flow direction, key chambers and other agreed asset information.
Reporting and mapping: We prepare the agreed deliverables, which include MSCC5-coded observations, drainage mapping, CCTV footage, supporting images and condition summaries.
Maintenance and remedial recommendations: Where issues are identified, we clearly highlight priority defects and recommend any cleaning, further investigation or remedial works required.
For larger sites, we can also help establish a programme for future inspections and ongoing drainage maintenance.
Why choose Clearflow Surveys?
Commercial drainage surveys need to provide more than CCTV footage. They should give facilities teams, property managers and asset owners clear information they can actually use to manage risk, maintenance and future expenditure.
Clearflow Surveys provides:
WRc- approved reporting, with clear identification of structural and service defects
Drainage mapping and asset identification to support ongoing site management
HD CCTV footage and supporting images
Clear identification of priority defects, maintenance requirements and areas needed further investigation
Practical recommendations for cleaning, repair and remedial works
Experience across commercial, industrial and multi-building sites
Flexible survey scopes for one-off investigations or recurring PPM programmes
Clear reporting suitable for facilities teams, property managers, contractors and asset owners
