Sewer encasement protects existing sewer pipes when construction takes place nearby. It reinforces the pipes to prevent damage from excavation or building loads.
When is a sideline connection required?
Sidelines are needed when a property requires a lateral sewer connection to the main sewer line, commonly for new developments or subdivisions.
Does sewer encasement require Sydney Water approval?
Yes. Sydney Water approval ensures the encasement meets safety and compliance standards. We manage the approval process for you.
How long does the installation process take?
Timelines vary based on complexity and approvals. We provide clear timelines and keep you informed throughout.
Can you upgrade or replace existing sewer infrastructure?
Yes. We offer both new installations and upgrades to existing sewer systems to meet current regulatory requirements.
