Wastewater Collection

Although sewer pipeline design is not usually a complicated process, there are several techniques RH2 staff use to ensure that our sewer designs are cost effective and low maintenance and will provide service for many years. These include the following:

  • RH2 staff members use computer modeling techniques to determine the optimum slope and depth of sewer pipelines, thus minimizing excavation and backfill costs.
  • Each sewer design project includes an investigation of materials that meet site-specific requirements, such as corrosion resistance, infiltration and inflow prevention, structural integrity, and hydraulic conditions.
  • Our staff is trained in the latest trenchless technology and considers the use of trenchless construction methods during the design process.
  • Usually there are alternative alignments available for a new or replacement sewer line. During the predesign phase, our staff develops a set of alternative alignments and determines the advantages and disadvantages of each. This process is summarized as part of a predesign report that includes a recommended alignment.
  • Construction observation of the sewer pipeline installation aides in the construction of the designed project and helps to minimize cost overruns related to change orders.
  • Recent developments in environmental regulations can have a significant impact on pipeline project costs and schedules. RH2 staff are able to recognize these impacts in the early stages of the project and properly address them during the alternatives analysis process.
