Understanding Underground Drainage Systems

Before we move further into specific issues, it’s crucial to understand the components that make up an underground drainage system:

• Main sewer lines: Large pipes that carry wastewater from individual properties to municipal treatment facilities.
• Lateral pipes: Smaller pipes that connect individual properties to the main sewer line.
• Manholes: Access points for inspection and maintenance of sewer lines.
• Catch basins: Curbside drains that collect stormwater runoff.
• Culvert pipes: Large pipes or tunnels channel water under roads or railways.
• Inspection chambers: Smaller access points for residential drainage systems.
• Soakaways: Subterranean structures designed to manage surface water runoff.

Each component is essential in efficiently removing water and waste from our properties and streets.

Common Underground Drainage Systems Problems And Solutions

Problem 1: Blockages And Clogs

Blockages are among the most frequent issues encountered by experts. They can occur due to various reasons:

• Accumulation of debris (leaves, silt, gravel)
• Grease and fat build-up from kitchen waste
• Tree root intrusion
• Flushing of non-biodegradable items (wet wipes, sanitary products)
• Pipe scale build-up in hard water areas

Fix: Hire experts who can provide advanced CCTV drain surveys to pinpoint blockages accurately. For minor clogs, high-pressure water jetting is often effective. In severe cases, they may use mechanical augers or excavation to remove the blockage completely.

Problem 2: Pipe Damage And Cracks

Underground pipes can develop damage over time due to:

• Ground movement or settling
• Corrosion (especially in older cast iron or clay pipes)
• External pressure from tree roots or heavy vehicles
• Freeze-thaw cycles in colder regions

Fix: Depending on the extent of damage, various solutions range from pipe relining and pipe bursting to complete pipe replacement. Experts will also use trenchless technologies where possible to minimise disruption.

Problem 3: Tree Root Intrusion

Tree roots are naturally attracted to the water and nutrients in sewer lines. They can infiltrate through small cracks or joints, causing blockages and further pipe damage.

Fix: There are many preventive measures and treatments for root intrusion:

• Chemical root treatments
• Mechanical root cutting
• Pipe relining with root-resistant materials
• Installation of root barriers

Problem 4: Improper Drainage System Installation

Poor installation can lead to a host of problems:

• Incorrect pipe gradients cause slow water flow
• Improperly connected joints leading to leaks
• Insufficient pipe capacity for the property’s needs
• Use of substandard materials

Fix: Experts will assess your system and recommend necessary corrections. This may involve re-grading pipes, replacing joints, or upgrading system components to meet current standards.

Problem 5: Collapsed Or Broken Pipes

Severe damage can lead to pipe collapse, causing significant drainage issues and potential property damage. The UK’s ageing infrastructure, with many sewers dating back to the Victorian era, makes this a growing concern.

Fix: While collapsed pipes often require excavation and replacement, experts offer trenchless repair methods like pipe relining where possible. This innovative technique can restore pipe integrity with minimal surface disruption.

Preventive Measures And Maintenance Tips

Prevention is always better and more cost-effective than cure. Here are some expert tips for maintaining your underground drainage system:

1. Regular inspections: Schedule annual CCTV pipeline inspections to detect potential issues early.
2. Proper waste disposal: Educate household members about properly disposing of fats, oils, and grease (FOG). Consider installing grease traps in commercial kitchens.
3. Tree management: Consult an arborist about tree placement and consider root barriers for trees near drainage lines.
4. Gutter maintenance: Keep gutters clean and ensure proper connection to the underground drainage system.
5. Professional cleaning: Schedule periodic cleaning to remove build-up and maintain optimal flow.
6. Water conservation: Reducing water usage can help prevent overloading of your drainage system.
7. Permeable paving: Consider permeable paving options for driveways and patios to reduce surface water runoff.

When To Seek Professional Help?

While property owners can manage routine maintenance, if you notice specific signs, call professionals immediately:

• Persistent slow drains or gurgling sounds
• Frequent backups or overflows
• Foul odours around drains or in your yard
• Visible sinkholes or wet spots in your lawn
• Multiple drains were affected simultaneously
• Visible mold or mildew growth
