Municipal Water & Wastewater Systems


Sewage separation & Drainage transport
In drainage networks where combined sewage and drainage are still carried in the same pipe, heavy rain routinely triggers overflow discharge. Nowadays, FRP pipes are widely adopted for newly built stormwater lines and reconstructed sewage laterals. They are leak-free; moreover, chemically inert wall structure prevents exfiltration of aggressive wastewater into surrounding soil and infiltration of groundwater into the sewage stream, helping cities meet drainage requirements and improve drainage resilience during peak storm events.
Trenchless repair of underground pipes
Across urban areas, some buried drainage and sewage networks have reached or exceeded their design life, suffering from circumferential cracking, joint dislocation, root intrusion, and infiltration-yet traditional open-cut replacement means prolonged road closures, utility conflicts, and heavy social cost. Replacement jacking pipe offers a smarter alternative to repair or replace underground urban pipes through trenchless methods, thereby modernizing urban infrastructure while minimizing negative impacts on the environment and residents' lives.
