Here's how trenchless water service replacement typically works:

• Assessment | First, a thorough inspection of the existing water service line is conducted. This assessment helps determine the extent of the damage and the suitability of trenchless methods for the specific situation.

• Preparation | Access points are created at both ends of the water service line. These access points could be existing utility openings or small pits dug at strategic locations.

• Trenchless Method Selection | The appropriate trenchless method is chosen based on the assessment. Common trenchless techniques used for water service replacement include pipe bursting, directional drilling, and pipe lining.

  • Pipe Bursting | A bursting head is pulled through the existing water line, breaking it apart. Simultaneously, a new, seamless pipe is pulled into the void created by the bursting head.

  • Directional Drilling | A new pipe is drilled horizontally underground, following a predetermined path. The new pipe is then pulled into place, replacing the old water line.

• Replacement | The chosen trenchless method is executed, replacing the old water service line with a new, durable pipe. The process is monitored and guided carefully to ensure the new pipe is installed accurately and securely.

• Quality Check | After the replacement is complete, the new water service line undergoes pressure testing and inspection to ensure it meets the required standards and functions properly.

• Site Restoration | Once the replacement is successful, any access points or small pits created during the process are filled, and the landscape or structures disturbed during the operation are restored

Trenchless water service replacement offers the benefit of minimal disruption, reduced restoration costs, and faster completion compared to traditional excavation methods. It is a practical solution for updating aging or damaged water lines without disturbing the surrounding environment significantly.

Various materials can be used for waterline replacement, and the choice depends on factors such as budget, soil conditions, local regulations, and the specific requirements of the project. Some common materials used for waterline replacement include …

• HDPE (High-Density Polyethylene) | HDPE pipes are known for their flexibility, strength, and resistance to chemicals and corrosion. They are often used for trenchless installations due to their flexibility and ability to withstand bending without breaking.

• Copper | Copper pipes are durable and resistant to corrosion. They are commonly used for residential water lines and are known for their long lifespan and reliability.

• PEX (Cross-linked Polyethylene) | PEX pipes are flexible and easy to install. They are often used for residential plumbing, including water supply lines. PEX pipes are resistant to scale buildup and are suitable for both hot and cold water applications.

• Ductile Iron | Ductile iron pipes are strong and durable, making them suitable for water mains and larger water supply lines. They are often used for municipal water distribution systems.

• Cast Iron | Cast iron pipes were commonly used in older constructions for water and sewage lines. However, they are heavy and prone to corrosion, leading to a gradual shift towards more modern materials.

The choice of material depends on factors such as the soil conditions, the presence of corrosive elements in the soil, the water quality, and the project budget. We consult with local authorities to determine the most appropriate material for waterline replacement in your specific area.
