1. Inspect Manholes and Gullies Regularly
Manholes and gullies are the hidden backbone of your commercial drainage system. Without regular inspection, these access points can deteriorate silently, leading to costly repairs and operational disruptions.
Why This Matters
Manholes serve as critical access points for maintaining buried sewer pipelines and preventing system failures. Gullies catch surface runoff and filter debris before water enters the storm sewer network. Both require consistent attention to function properly.
Regular inspection of manhole covers and adjustment rings identifies damage from vehicle traffic, weathering, or erosion before it becomes a major problem. Groundwater infiltration and surface water contamination happen quietly when these components fail.
What to Check During Inspections
When you visit each manhole and gully, assess these key elements:
- Structural integrity of covers, frames, and adjustment rings
- Water pooling or flooding around the perimeter indicating subsidence or displacement
- Visible cracks, corrosion, or deterioration in concrete or metal components
- Debris accumulation that could block flow or damage pipes
- Changes in ground level around the manhole suggesting underground movement
Frequency and Documentation
Professional property managers in the southern UK typically inspect manholes and gullies every three to six months. High-traffic areas or older installations may need quarterly checks. Document findings with photographs and dates to track deterioration patterns over time.
Regular inspection prevents small problems from becoming emergency drainage failures that disrupt your operations and drain your budget.
Keep records showing condition assessments, repairs completed, and any professional services called. This documentation protects your property, supports insurance claims, and helps budget for maintenance.
When to Call Professionals
If you spot cracks, misalignment, or structural damage, contact a drainage specialist immediately. CCTV drain surveys can examine the pipework beneath these access points without excavation, revealing hidden problems inside the system.
Pro tip: Schedule inspections on a fixed quarterly date aligned with your property maintenance calendar, so the task becomes routine rather than overlooked, and you’ll spot developing issues before they worsen.
2. Check for Blockages and Unpleasant Odours
Blockages and odours are your drainage system’s way of sending distress signals. These two warning signs often appear together, indicating stagnation, debris buildup, or worse problems lurking beneath the surface.
Understanding the Connection
Blockages trap water, which then stagnates and releases foul odours. Fat, debris, and sediments accumulate over time, restricting flow and creating conditions where bacteria thrive. The smell gets stronger as the blockage worsens.
Odours from your drains signal that something needs attention before it becomes an emergency. What starts as an unpleasant smell can quickly escalate into backed-up toilets, flooded basements, or structural damage to your property.
What Causes Blockages in Commercial Properties
Commercial buildings face unique drainage challenges compared to residential homes. Consider these common culprits:
- Fat and grease from kitchens, restaurants, or food preparation areas
- Soap residue and hair from bathrooms and washing facilities
- Foreign objects accidentally flushed down toilets or drains
- Sediment accumulation from years of normal usage
- Tree root intrusion into older pipes or cracks in the system
Spotting the Problem Early
Identifying blockage signs and odours before they become severe saves money and disruption. Listen for gurgling sounds when water drains, watch for slow draining sinks or showers, and notice if puddles form around drains or in car parks.
These observations following inspection standards help develop appropriate maintenance plans before major rehabilitation becomes necessary.
Taking Action
When you detect blockages or persistent odours, document the location, frequency, and severity. This information helps drainage specialists diagnose the problem accurately and recommend the right solution.
Catching blockages early prevents them from evolving into system failures that damage your property and disrupt business operations.
For commercial properties, regular drain cleaning prevents most blockages from occurring. Professional drain clearing removes accumulated debris and restores proper flow before backups happen.
Pro tip: Schedule preventative drain cleaning annually for commercial kitchens and every 18 to 24 months for other areas, and always document when odours first appear so you can track patterns and catch recurring issues before they escalate.
3. Schedule Professional CCTV Drain Surveys
CCTV drain surveys reveal what your eyes cannot see. Underground pipes hide blockages, structural damage, and deterioration that manual inspection alone will never detect.
What CCTV Surveys Actually Do
Closed-circuit television cameras travel through your drainage pipes, recording everything along the way. The footage shows blockages, cracks, infiltration points, and areas where tree roots have invaded the system. This technology eliminates guesswork from drainage assessment.
Instead of digging up your car park or gardens to investigate problems, cameras do the reconnaissance work. You get clear visual evidence of what needs fixing and where the problems lie.
Why This Matters for Commercial Properties
Using CCTV inspection technology identifies structural deterioration and hydraulic issues early, supporting proactive maintenance before costly failures occur. This standard practice assesses pipe conditions accurately and helps plan effective rehabilitation strategies.
Commercial drainage systems handle higher volumes of traffic than residential drains. Early detection prevents emergencies that could shut down your business, flood tenanted spaces, or damage neighbouring properties.
What the Survey Reveals
CCTV surveys provide detailed information about your drainage system’s actual condition:
- Blockage locations and severity from grease, debris, or root intrusion
- Structural defects such as cracks, fractures, or pipe misalignment
- Infiltration points where groundwater or surface water enters the system
- Deterioration patterns showing where pipes are failing
- Sediment accumulation restricting water flow
When to Schedule Surveys
Schedule CCTV surveys every three to five years as part of your preventative maintenance programme. Properties with recurring drainage issues need surveys annually. New acquisitions or pre-purchase inspections require baseline surveys to understand existing conditions.
CCTV surveys transform drainage maintenance from reactive emergency response into proactive long-term planning.
Documentation from surveys becomes invaluable for insurance claims, tenant disputes, and future maintenance planning. Keep records showing pipe conditions over time so you can track deterioration and budget accurately.
Pro tip: Request written reports with still photographs and GPS coordinates of problem areas, as these records help justify maintenance expenditure to stakeholders and provide proof of due diligence should issues arise later.
4. Ensure Drains Are Free from Debris and Fat
Fat and debris are the silent killers of commercial drainage systems. They accumulate quietly, reduce pipe capacity, and eventually cause backups that disrupt operations and damage your property.
Why Fat and Debris Matter
Fat solidifies as it cools, coating pipe walls and trapping other debris. Over time, this buildup narrows pipes until water can barely flow through. Debris like food scraps, paper products, and general waste accelerates the problem.
Commercial kitchens are particularly vulnerable since cooking fat enters drains constantly. Bathroom drains collect hair, soap residue, and personal care products. Even office drains accumulate dust and particles that restrict flow over months.
The Real Cost of Neglecting This
Preventative cleaning and monitoring maintains unobstructed flow and reduces the risk of overflows or backups that cause operational disruptions. Regular removal of accumulated debris supports system efficiency and saves money long term.
When fat blockages occur, you face emergency call-outs, expensive clearing costs, and potential environmental fines if contaminated water spills into public sewers or surrounding land.
Practical Prevention Strategies
Keeping drains clear requires both prevention and maintenance. Implement these approaches:
- Install grease traps in kitchen areas to capture fat before it enters main drains
- Use drain screens to catch food particles and debris at sink outlets
- Train staff on what can and cannot go down drains
- Schedule regular drain cleaning to remove accumulated buildup before blockages form
- Inspect gully traps monthly and remove visible debris by hand
Cleaning Frequency Matters
Commercial kitchens need drain cleaning every four to eight weeks depending on usage volume. Standard office buildings typically require cleaning every six to twelve months. Properties with persistent fat issues benefit from quarterly professional cleaning.
Regular debris and fat removal prevents emergency blockages that disrupt business and create costly repairs.
Keep records of cleaning dates and findings. This documentation helps you spot patterns and adjust cleaning schedules based on actual conditions rather than guessing.
Pro tip: Install simple drain maintenance reminders on your maintenance calendar for different zones (kitchens, bathrooms, general areas), and photograph drain conditions after each professional cleaning to track accumulation rates over time.
5. Review Maintenance Records and Repairs
Your maintenance records are a goldmine of information about your drainage system’s true condition. Reviewing them reveals patterns, predicts future problems, and protects your investment.
Why Records Matter
Records show what has been done, when it was done, and what the results were. This history helps you understand whether repairs actually solved problems or just postponed them temporarily. Without records, you’re essentially starting fresh each time an issue arises.
Maintenance documentation following industry standards provides consistent data that tracks recurring issues like infiltration, cracks, or blockages. This information becomes invaluable when planning repairs or justifying budget requests to stakeholders.
What to Document
Comprehensive records of inspections and repairs inform future maintenance decisions and ensure long-term system performance. Your records should capture:
- Inspection dates and findings from visual checks and professional surveys
- Repair descriptions including what was fixed and how
- Parts replaced with dates and supplier information
- Cost details for budgeting and trend analysis
- Contractor information for follow-up work or warranty claims
- Photographs showing conditions before and after repairs
Finding Patterns in Your Data
Look at your records and ask yourself critical questions. Do certain drains repeatedly block? Do particular areas flood during heavy rain? Are repairs to one section failing within months of completion?
These patterns reveal systemic problems requiring comprehensive solutions rather than temporary fixes. A drain that blocks every six months suggests infiltration or structural issues, not just grease accumulation.
Using Records for Planning
Review maintenance history when budgeting for the upcoming year. Properties with recurring blockages need budget allocation for preventative cleaning. Buildings showing increasing repair costs may need more substantial rehabilitation soon.
Maintenance records transform reactive emergency repairs into strategic, budget-friendly planning.
Share this information with drainage specialists when requesting quotes. Their recommendations will be more accurate and cost-effective when they understand your system’s history.
Pro tip: Create a simple spreadsheet tracking inspection dates, issues found, repairs completed, and costs, then review it quarterly to spot trends and schedule preventative work before problems become emergencies.
6. Test Emergency Access and Response Plans
When drainage disasters strike, you need to respond fast. Testing your emergency plans now ensures you’re ready when pipes fail and minutes matter.
Why Testing Matters
Emergency plans look good on paper until you actually need them. Testing reveals gaps, identifies who needs training, and confirms that contractors can reach your property quickly. A plan that fails during a crisis is worse than no plan at all.
Drainage system failures create public health risks, environmental hazards, and business disruptions. Swift response capability during emergencies reduces these dangers significantly and limits damage to your property.
Essential Elements of Your Response Plan
Emergency preparedness includes maintaining contact lists for contractors and ensuring personnel understand safety protocols and traffic control measures. Your plan should cover:
- Contact information for emergency drainage specialists, with 24/7 availability confirmed
- Access routes to all drainage structures, with clear instructions for opening gates or removing obstacles
- Safety protocols for staff entering drainage areas or watching repair work
- Traffic control measures if repairs affect car parks or driveways
- Notification procedures for tenants, neighbours, and local authorities if required
Testing Your Access Points
Walk through your property and physically test access to every manhole and drainage structure. Can you actually open the covers? Are access routes clear of parked vehicles, storage, or obstacles? Do gates lock properly and can authorised personnel access them quickly?
Note any problems and fix them before emergencies occur. A manhole cover stuck with paint or corrosion cannot be opened during a crisis.
Training and Communication
Ensure staff know what to do if they discover flooding, backed-up toilets, or foul odours. Create simple written instructions showing what constitutes an emergency versus a maintenance issue. Schedule annual reviews of your plan with all relevant personnel.
Emergency preparedness prevents panic and ensures coordinated responses that minimise damage and health risks.
Keep your contact list updated quarterly. Contractors relocate or change numbers regularly, so verify information before you need it.
Pro tip: Conduct a quarterly “emergency response drill” where you check contact numbers, verify access routes, and walk through your response procedures, treating it like a real incident to identify actual bottlenecks.
