Maintaining a properly functioning wastewater collection and treatment system is essential to protecting your community. Our wastewater division’s knowledgeable staff is experienced in all areas of collection and treatment. We can help you with:

Evaluation and condition assessment

Our wastewater discipline includes National Association of Sewer Service Companies-trained staff who coordinate the televising of sewer assets and perform detailed condition assessments of those assets. From there, we can determine if the asset is sound, needs rehabilitation or will require removal and replacement. Our staff is certified in:
  • the Lateral Assessment Certification Program
  • the Manhole Assessment Certification Program
  • the Pipeline Assessment Certification Program

Rehabilitation

If you have an asset that needs rehabilitation, our staff is certified to observe installations for conformance with lining and rehabilitation services, including:

  • cured-in-place pipe rehabilitation
  • lateral sewer tap rehabilitation using T-liners
  • manhole rehabilitation using cementitious repairs; structural repairs curtain grouting; and cured-liner
  • systems and spray-on, two-part coating systems

Wastewater system planning

As your community grows, our staff can evaluate growth trends, forecast system expansion and provide recommendations for system capacity and additional treatment. We can package the planning into facility-planning documents tailored to meet the requirements of multiple funding agencies and help in the pursuit of loan or grant funds.

Wastewater design services

Our wastewater discipline has a skill set to cover design from the point a drop of water goes down a customer’s drain until it is discharged back into a stream or river after treatment. Our services cover:

  • Gravity sewers: We can design a new or replacement sewer from 8 inches diameter and up. Our team’s experience includes many materials, from connecting to hand-laid brick sewers, aged concrete sewers and clay tiles to modern polyvinyl chloride and fiberglass piping.
  • Sanitary lift stations: Our long history of lift station design ranges from individual, residential stations up to multi-pump networks with shared force mains. Our design team has tackled complex pumping scenarios, as well as designs for future expansion and growth.
  • Sanitary force mains: Force main design goes hand in hand with lift station design. Our team regularly designs force mains for simple systems and complex, multi-station networks, evaluating system hydraulics carefully to keep the flow moving and stations at the right capacity.
  • The contractor also sprayed an epoxy coating in the manholes during the rehabilitation of the Cook Street Sewer District's combined sewer system.

    Treatment: Our wastewater discipline can tackle treatment plant designs of all sizes. Our resume includes small, on-site treatment; facultative and aerobic lagoons; and traditional treatment using activated sludge. We can assist with automatic and manual plant screening, multiple methods of grit removal, aerobic treatment through activated sludge, membrane bioreactors, clarification, tertiary filtration using various sand and fabric filter systems, disinfection using chlorine and ultraviolet systems and small package treatment units for decentralized systems.

Program management

For many communities, timing and locating funding matter as much as the design project itself.  We can help you with funding applications for multiple state and federal agencies. We have grant-writing staff who can identify grant opportunities and help you apply for the funding. Our team can create a capital improvement plan that fits within your funds and identify multiyear infrastructure plans. We can help with:

  • loan and grant applications and administration, including federal and state programs
  • capital improvement program development
  • impact fee analysis, updates and implementation
  • budgeting assistance
  • debt service calculations
  • operations and maintenance assistance
