Blocked Sewers

Blocked sewers are a serious issue that can cause health hazards, environmental contamination, and property damage. Sewers are responsible for transporting wastewater, including human waste, from households and commercial buildings to wastewater treatment plants. When the sewer system becomes blocked, it can result in sewage backups, which can be dangerous and expensive to clean up. That’s why it’s important to call us as early as possible in order to help prevent the following:

1. Health Hazards

Blocked sewers can create significant health hazards. Sewage backups can cause foul odours, which can lead to respiratory problems, headaches, and nausea. Sewage backups can also contaminate the environment, including local water sources, which can have long-term effects on human health and wildlife. Sewage contains harmful bacteria, viruses, and parasites that can cause illnesses, including diarrhea, vomiting, and infections.

2. Property Damage

Blocked sewers can cause severe property damage. Sewage backups can cause water damage, which can lead to mould growth, structural damage, and electrical problems. Sewage backups can also damage personal belongings, including furniture, electronics, and clothing. Cleaning up after a sewage backup can be expensive and time-consuming, and it may require the services of a professional restoration company.

3. Environmental Contamination

Blocked sewers can contaminate the environment, including local water sources. When sewage backups occur, the sewage can seep into the ground, contaminating the soil and groundwater. This can have long-term effects on human health and wildlife. Sewage contains harmful bacteria, viruses, and parasites that can harm plants, animals, and aquatic life.

4. Insect and Rodent Infestations

Blocked sewers can create ideal conditions for insect and rodent infestations. Sewage backups can attract flies, mosquitoes, and other insects, which can carry diseases and spread bacteria. Sewage backups can also attract rodents, including rats and mice, which can carry diseases and cause property damage.

Sewer Repairs

Sewer repairs are a crucial part of maintaining a healthy and functional sanitation system. Sewers are responsible for transporting wastewater, including human waste, from households and commercial buildings to wastewater treatment plants. If there are issues with the sewer system, it can result in serious health and environmental hazards.


Sewer repairs involve fixing any damage to the pipes or the surrounding infrastructure that could cause sewage backups or leaks. Sewer pipes can become damaged for various reasons, including age, tree roots, ground shifts, and heavy usage. Common signs of sewer problems include slow drains, sewage backups, foul odours, and sewage seeping up through the ground.

How are Sewer Repairs performed?

Sewer repairs typically start with a sewer inspection, which involves sending a camera through the pipes to identify the location and cause of the damage. Once the problem has been identified, the sewer repair technician will decide on the most appropriate course of action. Sewer repairs can be done using several different techniques, depending on the severity and location of the damage.


One of the most common sewer repair techniques is to replace the damaged section of the pipe. This involves digging a trench to access the damaged pipe, removing the damaged section, and replacing it with a new pipe. This method is effective but can be time-consuming and expensive, as it requires digging up the ground to access the pipes.


Another technique is trenchless sewer repair, which involves repairing or replacing the damaged pipe without digging up the ground. This is done by accessing the sewer through small access points and using specialised equipment to insert a new lining into the existing pipe. This method is faster and less disruptive than traditional sewer repair methods, but it may not be suitable for all types of damage.

Why are Sewer Repairs essential?

Sewer repairs are essential for several reasons. Firstly, they ensure that the sewage system functions correctly, which is crucial for public health and safety. A damaged sewer system can cause sewage to back up into homes and businesses, which can result in a health hazard and damage to property. Sewage leaks can also contaminate the environment, including local water sources, which can have long-term effects on human health and wildlife.


Secondly, sewer repairs can prevent more extensive and costly damage in the future. If a damaged sewer pipe is left untreated, it can cause more severe damage, leading to more significant repairs and higher costs. It is essential to address any sewer problems as soon as they are identified to prevent them from becoming more severe.
