Infiltration/Inflow (I/I)

 

Challenges

Infiltration/inflow (I/I) – or surface and groundwater that enters a system – greatly reduces the capacity of sewers to carry wastewater and can adversely affect the performance of a wastewater treatment plant. It’s also not uncommon for basement flooding or sanitary sewer overflows to occur because of I/I.

All sanitary sewer systems have I/I. The challenge is to reduce excessive I/I.

 

Experience

Jones & Henry can help a community address I/I problems in a cost-effective manner. Our experience with I/I has resulted in several solutions to different I/I problems including:

  • Equalization at the Wastewater Treatment Plant and in the System
  • Express Sewers
  • Foundation Drain Removal
  • In-Line Storage
  • Internal Sewer Grouting
  • Manhole Rehabilitation
  • Public Awareness Program
  • Sanitary Relief Sewers
  • Sewer Lining
  • Sewer Replacement

Jones & Henry provides full, tailored services to develop comprehensive programs to remove excessive I/I:

Data Collection:
  • Continuous Flow Monitoring
  • Smoke Testing Sewers
  • Dye Testing of Sewers
  • Visual Inspection
  • Manhole Evaluations
  • Camera Inspection
Preliminary Analysis:
  • Statistical Review of Wastewater Treatment Plant Flows

  • Analysis of Past Flooding Problems
  • Project Report and Recommendations
  • Review of Operating Problems Caused by I/I

Combined Sewer Overflows (CSO)

 

What are Combined Sewer Overflows?

Combined sewers convey both sanitary and storm flow. The combined storm and sanitary flow frequently exceeds the capacity of interceptor sewers and treatment plant and can cause overflows of untreated wastewater. These events are referred to as Combined Sewer Overflows (CSOs).

 

Experience

Jones & Henry has worked on CSO abatement for municipalities and sewer districts with populations ranging from 3,000 to 500,000. The firm has encountered practically every conceivable situation and performed many tasks required for a successful program.

We are highly experienced in preparing plans, assisting during construction, preparing O&M materials, and training personnel in the operation and control of CSO abatement facilities. Jones and Henry’s CSO abatement planning results in programs that can be implemented without overwhelming municipal finances.

 

Services

Jones & Henry is experienced in providing all the services necessary to arrive at an appropriate CSO abatement plan and the design of required facilities, including:

  • CSO system inventory and mapping
  • Metering and sampling
  • Model development
  • Water quality impacts
  • Financial capability analysis
  • Plan preparation, including proposed schedules
  • Assistance with permit and schedule negotiations
  • Public participation
  • Design of improvements
  • Engineering during construction
  • Start-up assistance
  • Personnel training

Treatment

 

Challenges

Providing effective wastewater treatment is one of the greatest challenges facing public and private entities today. Ever-changing regulations covering effluent quality and residuals, the need to negotiate National Pollutant Discharge Elimination System (NPDES) permit conditions, and the fact that public entities often have to respond to the needs of local industries make wastewater treatment especially difficult.

Realistically, the challenges associated with wastewater treatment never disappear – but that doesn’t mean they’re impossible to mitigate.

 

Wastewater as a Resource

Our approach to wastewater treatment is to view wastewater as a resource.

Treated effluents can often be used as cooling water or for irrigation, while residuals are often used to generate methane or land applied as fertilizer. The value of the resource varies widely based on the extent of treatment required, on the local cost of fresh water, and the need for soil amendments –we will work your unique needs so that properly-treated wastewater and residuals resulting from treatment are operationally utilized by their communities and local industries.

 

Experience

Jones & Henry has extensive experience in all kinds of domestic and industrial wastewater treatment and residuals treatment, disposal or utilization. This includes:

  • Planning for wastewater treatment
  • Evaluation of treatment processes including pilot studies
  • NPDES permit negotiations and public participation
  • Design of facilities
  • Assistance during construction and start-up
  • Operation and maintenance
  • Financial planning including grant procurement
  • Nutrient removal
  • Wet weather treatment
  • Treatment Plant Modeling

Residuals, Energy Efficiency & Biogas

 

Challenge

As many municipalities explore alternative energy sources for their wastewater treatment plants, many have turned to anaerobic digestion and other residuals as viable solutions.

Anaerobic digestion occurs when microorganisms break down biodegradable material like sewage sludge, creating biogas. Biogas can either generate heat and electricity when it is combusted or be processed into renewable transportation fuels and natural gas.

There is a growing concern over the cost-effective treatment and environmentally responsible use of residuals. New regulations on biosolids disposal and air emissions, coupled with the dwindling capacity of landfills, have forced many communities and industries to consider new and improved management methods.

The only way to overcome this is through a well-planned approach for residuals management, which Jones & Henry specializes in.

 

Residuals as a Resource

Residuals can be assets – resources, even. We have developed numerous programs based on the use of biosolids on agricultural land. We also develop methane-fueled systems which generate and use methane derived from the anaerobic digestion of biosolids.

 

Experience

Jones & Henry has helped many clients develop residuals management systems. Over the years, our professional staff of engineers and certified operators has gained considerable experience in pilot testing, designing, optimizing, and troubleshooting residual solids programs.

Our experienced, competent staff members will identify the methods or approaches that need to be implemented to enhance energy management in operating facilities and determine payback methods.

Services

Jones & Henry provides the services needed to develop and implement practical and sound management programs. We also have the technical background to develop innovative approaches.

Our services include:

    • Evaluating alternative solutions
    • Selecting alternatives during the design phase
    • Ensuring a functional, reliable, economical, and operable facility

    • Optimizing and troubleshooting problems
    • Preparing residual management plans

    • Designing anaerobic digestions systems
    • Designing digester gas utilization and handling systems

In summary, we can offer you a complete range of services to design and implement an effective residuals management system.


Sewer Modeling

Throughout our 90+ years of operation, Jones & Henry has helped numerous communities to evaluate the capacity of their water collection systems and propose solutions.

In recent years, we’ve provided computer sewer models and assisted communities with gaining a clear understanding of their collection systems.

Sewer system models help communities like you to view flow levels, velocities, and surcharge conditions in many areas of your sewer network, all at the same time. We use these models to develop “What if?” scenarios to simulate proposed system modifications prior to construction.

These models can also help you evaluate downstream impacts to determine the best holistic design solution for your water collection system.

 

Sewer System Model Services

Some services we provide for developing a sewer system model include:

  • Model development
  • Flow monitoring for model calibration and I/I assessments
  • Development of programs for system improvement
  • Training owner-employees in the use of the modeling software

 

Benefits of Sewer System Models from Jones & Henry 

Our sewer system models can help you with:

  • Assessing your system’s capacity under various flow scenarios
  • Assessing capacity-related issues like overflows, basement backups, street flooding, and more
  • Determining how a system expansion might affect your overall operation
  • Examining effects before and after rehabilitation
  • Optimizing the operation, maintenance, and rehabilitation of your sanitary sewer collection systems

When our study is complete, we will provide you with the system model for ongoing use.
