Why Do Drains Smell in Summer? Common Causes and Solutions in Derby
Most people expect drainage problems to become more common during winter storms or periods of heavy rainfall. However, summer often brings a different type of issue that catches homeowners and businesses by surprise.
Bad drain smells.
As temperatures rise, unpleasant odours coming from drains, gullies and manholes become far more noticeable. While the smell itself is unpleasant, it’s often a warning sign that your drainage system needs attention.
At Drain2Drain, we receive numerous enquiries during warmer months from customers across Derby who are concerned about foul smells around their property. The good news is that the cause can usually be identified and resolved quickly.
Why Are Drain Smells Worse During Hot Weather?
Warm temperatures speed up the breakdown of organic waste inside drainage systems.
Grease, food waste, soap residue and other debris naturally produce gases as they decompose. During hotter weather, these processes happen faster, causing smells to become stronger and more noticeable.
Lower rainfall during summer can also play a part. Rainwater often helps flush drainage systems naturally. During prolonged dry periods, debris can sit within pipework for longer, increasing the likelihood of odours developing.
Blocked Gullies and Surface Water Drains
One of the most common causes of summer drain smells is a blocked gully.
Leaves, dirt, moss and general debris can accumulate over time, particularly around external drains. As organic matter begins to break down, unpleasant odours can develop.
If left untreated, blocked gullies can also cause standing water and increase the risk of flooding during sudden summer downpours.
Regular cleaning helps keep surface water systems flowing freely and prevents smells from developing.
Build-Up Inside Drain Pipes
Many drainage issues start gradually.
Grease, fat, food waste and other materials stick to the inside of pipework over time. While drainage may still function normally, these deposits create the perfect environment for bacteria and odour-producing gases.
Often, customers notice bad smells long before they experience a blockage.
Professional drain jetting can remove this build-up and restore the pipework to a much cleaner condition.
Problems With Commercial Drainage Systems
Businesses can be particularly vulnerable to summer drainage smells.
Restaurants, cafés, pubs, hotels and leisure venues often have drainage systems that work hard throughout the year. Grease and waste build-up can quickly create odour issues if maintenance is neglected.
For customer-facing businesses, unpleasant smells can create a poor first impression and negatively affect the customer experience.
Routine commercial drain maintenance is often the best way to avoid these issues altogether.
Could It Be a Damaged Drain?
Sometimes smells are caused by more than simple build-up.
Cracked or damaged pipework can allow odours to escape before wastewater reaches the main drainage network. In some cases, underground damage can go unnoticed for months until smells begin appearing around the property.
If odours persist despite cleaning and maintenance, further investigation may be required.
A CCTV drain survey can often identify hidden defects within the drainage system.
How to Prevent Summer Drain Smells
There are several simple ways to reduce the risk of drainage odours during warmer weather:
Keep gullies free from leaves and debris.
Avoid pouring fats, oils and grease down sinks.
Arrange routine maintenance for heavily used drainage systems.
Investigate persistent smells before they develop into larger issues.
Consider a CCTV drain survey if odours continue without an obvious cause.
