When most people think about drains, they picture simple underground pipes that carry away wastewater. In reality, drainage systems are one of the most important pieces of infrastructure in modern society. They quietly protect our homes, businesses, and communities from flooding, health risks, and costly structural damage.
In this blog, we’ll explore the history, function, and importance of drainage systems, highlight common problems that occur, and explain how professional services such as United Drains keep them running smoothly.

Why Drainage Matters
Drains are often out of sight and out of mind, until something goes wrong. Without effective drainage networks:
• Streets would flood during heavy rainfall.
• Sewage could back up into homes and workplaces.
• Public health risks, such as bacteria, parasites, and pests, would increase.
• Infrastructure damage would lead to expensive repairs and business downtime.
According to the UK Environment Agency, effective drainage is a vital part of flood prevention strategies across the country. With more frequent extreme weather events, the importance of well-maintained drains is greater than ever.
A Brief History of Drains
Drainage is not a modern invention. Ancient civilisations, such as the Romans, were pioneers of sewer networks. London’s Victorian sewer system, designed by Sir Joseph Bazalgette in the 19th century, transformed public health by drastically reducing cholera outbreaks.
Today’s systems are more advanced, but the principle remains the same: safely move wastewater and stormwater away from where people live and work.
Common Drainage Issues
Even the most well-engineered system can run into problems. The most common issues include:
1. Blockages – Fat, oil, grease, wipes, and other debris can build up inside pipes.
2. Collapsed Pipes – Old or weakened pipes may crack and collapse, leading to major disruption.
3. Tree Root Intrusion – Roots naturally seek water and can penetrate drains, causing leaks and blockages.
4. Flooding – Heavy rain can overwhelm drains, especially in urban areas with little natural absorption.
5. Bad Odours – Often a sign of partial blockages or stagnant wastewater.
When these issues arise, professional intervention is essential. United Drains’ drain unblocking services provide fast solutions that prevent small issues from turning into bigger, costlier problems.
How Professional Drainage Services Help
Specialist engineers use state-of-the-art technology to keep drains in top condition. Services include:
• CCTV Drain Surveys – High-definition cameras identify blockages, cracks, and root intrusions without excavation.
• Drain Unblocking – Using high pressure water jetting and mechanical equipment to clear obstructions.
• Preventive Maintenance – Scheduled cleaning reduces the risk of emergency callouts.
• Emergency Response – 24/7 callouts ensure homes and businesses are protected any time of day.
For example, CCTV drain surveys are now a standard practice before buying a property or beginning major building works, providing peace of mind and avoiding unexpected repair bills.
The Role of Businesses in Drainage Care
Commercial premises, from restaurants to warehouses, rely heavily on functioning drains. Grease traps, regular cleaning, and compliance with environmental regulations all play a part in keeping systems effective.
Failure to maintain drains can lead to fines, reputational damage, and even forced closure. In fact, Thames Water reports that “fatbergs”, huge blockages caused by grease and wipes, cost millions of pounds every year to clear from London’s sewers.
Businesses can protect themselves with United Drains’ commercial drainage services, ensuring compliance while avoiding unnecessary costs.
Drainage and the Environment
Good drainage doesn’t just protect homes and businesses; it helps protect the environment. Poorly managed wastewater can pollute rivers and natural habitats, harming wildlife. By keeping drains clear and functional, we ensure that water is processed safely and sustainably.
The UK Government’s water quality strategy emphasises the role of responsible drainage management in safeguarding the environment for future generations.
