Sewer and Watermain Design

We Offer:

  • Metallic Watermain Replacement and Rehabilitation: Our team specializes in the replacement and rehabilitation of municipal water supply and distribution systems, including the replacement of substandard service connections, valves, valve chambers, fire hydrants, and connections to existing watermains, to prevent future degradation while ensuring safe and reliable water to consumers. We excel in providing comprehensive design solutions that prioritize efficiency, durability, and cost-effectiveness, ensuring enhanced performance and longevity of watermain infrastructure. 


  • Sanitary Sewer Design: Accardi Schaeffers has extensive experience in designing wastewater management and sanitary sewer systems, including free-flowing gravity and pressurized forcemain systems, and actively works towards resolving issues related to inflow and infiltration. Our team works closely with clients to develop designs that optimize system performance, adhere to regulatory standards, and minimize disruptions to existing infrastructure.


  • Trunk Watermain Installation and Rehabilitation: We provide comprehensive design and engineering services for trunk watermain installations and rehabilitation. Our services include feasibility studies, temporary by-pass plans, evaluation of pipe materials, and the incorporation of innovative trenchless techniques such as Cured-in-Place Pipe (CIPP) liners, horizontal directional drilling (HDD), microtunneling, and jack and bore augering. We navigate the necessary approvals and permits to ensure a smooth construction process.
  • Hydraulic Modeling and Drainage Design: Accardi Schaeffers uses advanced modeling software to analyze pre- and post-construction flows, assess the impact on existing infrastructure, and develop effective drainage and grading designs. Our team considers factors such as stormwater management, runoff reduction, and landscape design integration to create sustainable and functional drainage solutions.
