For more than 55 years, pressure sewer systems powered by grinder pumps have emerged as an effective solution for septic tank and cesspool replacement projects.

A pressure sewer system consists of a network of small-diameter pipes that move wastewater from individual homes or buildings to a central collection point, typically a treatment plant or a larger sewer system. Grinder pumps, which are installed at each individual property, break down solid waste and pump it into the pressurized pipes.

One of the key applications of pressure sewer systems is in “septic-to-sewer” or “cesspool-to-sewer” projects. In these projects, an established community has chosen to enhance environmental and public health quality with a centralized wastewater collection system.

Beyond the technical advantages of pressure sewers, the practical and logistical simplicity of deploying the system often results in a more affordable and sustainable solution for the community.

Specifically, the footprint of pressure sewers is much smaller than alternatives such as gravity sewers or septic tank effluent pumping (STEP) systems. Furthermore, the constructability of pressure sewers enables minimal disruption to the local communities, avoids damage to private property and existing vegetation, and returns valuable land back to the community.

This webcast will highlight the benefits and best practices of grinder pump pressure sewers in these septic-to-sewer and cesspool-to-sewer projects. These best practices are the results of several decades of working across the United States and five continents. Examples of these best practices in action will be shared through various real-world projects and case studies.

Learning Objectives:

Upon conclusion of the webcast, attendees will:

• Gain an understanding of the history of pressure sewer as well as the most common applications and benefits.
• Recognize the benefits, differentiators, common missteps and keys to successful septic-to-sewer or cesspool-to-sewer projects.
• Gain an appreciation for how stakeholders can leverage pressure sewers to improve environmental quality of life.
• Understand how pressure sewers can be a catalyst to facilitate more septic-to-sewer or cesspool-to-sewer projects.

February 2025

More municipalities and engineering firms are relying on the pressure sewer solution in today’s challenging environmental and economic conditions. Pressure sewer systems, incorporating semi-positive displacement (SPD) grinder pumps, have proven to be a practical and appropriate solution to providing central wastewater collection throughout the world.

"Pressure Sewer Design & Application on Long Island, NY*" provides an overview of pressure sewer systems that prove useful to those involved in the design and execution of a collection sewer program. Learn how grinder pumps are applied in new sewer systems, septic- and cesspool-to-sewer replacement projects, and are instrumental in fixing failing gravity systems.

Pressure sewer systems provide critical infrastructure with lower lifecycle costs, fewer community disruptions, and minimal environmental impacts compared to the construction of new gravity sewer or the rehabilitation of failed gravity systems.

This is a must-watch webinar for engineers searching for alternatives and improvements to traditional gravity sewer systems or for Long Island’s septic- and cesspool-to-sewer replacement projects.

Avoiding Dangerous Curves with Pressure Sewer Systems

November 2021, Part One

Grinder pumps - the heart of pressure sewer systems - are available as either centrifugal or progressing cavity designs. These pumps have significantly different performance characteristic curves, and can have notable impacts on the design, operation, and costs of pressure sewer systems. Part one of our webinar series explores the considerations and potential pitfalls on the type of pump used in pressure sewer systems. The distinct design methodologies will be discussed and the typical operation parameters such as system pressure measurements over time, pump cycle times, and pump run occurrences will be reviewed.

This is part 1 of E/One's Webinar Series: Design & Performance of Pressure Sewer Systems.

Validating the Design Methodology for Pressure Sewer Systems

November 2021, Part Two

Due to the fundamental characteristics and operational parameters of pressure sewers, the design methodologies differ markedly from gravity sewers. Part two of our webinar series provides a summary of the evaluation and results validating the methodology for the design of pressure sewer systems using the Probability Method and SPD grinder pumps.

Introduction to Pressure Sewers 

April 2020

In today's challenging economic environment, more municipalities and engineering firms are relying on the pressure sewer solution. This is a must-see webinar for anyone searching for alternatives and improvements to traditional gravity sewer systems or for septic-to-sewer replacement projects.

This webinar will provide an overview of grinder pump systems that will educate engineers, developers, operators, and consultants. Learn how ALL-TERRAIN SEWER driven by E/One grinder pumps are applied in new sewer systems, sewer renewal projects, and are instrumental in fixing failing gravity systems.

This webinar was originally broadcast April 7, 2020. 

Life Cycle Cost Comparisons: Pressure Sewers vs Gravity Sewer and Vacuum Sewer Systems

Using the Life Cycle Cost Calculator for Sewer Project Evaluations

October 2018

How much does a sewer system cost? What are the life cycle costs of a sewer system? This webinar provides a holistic overview of life cycle cost analysis and the cost comparisons of pressure sewer systems to other central sewer technologies.

When evaluating wastewater collections system options, the true cost of long-term ownership has often been improperly considered. Evaluation tools, such as E/One’s Life Cycle Cost calculator, provide a planning level assessment for the evaluation of long-term life cycle costs between a low pressure sewer system and a conventional gravity sewer.

This must-see webinar will review cost and operational parameters of a project’s needs. Capturing all operational activities and basing costs on actual or historic data ensures a more complete assessment and facilitates the selection of the wastewater collection system with the most favorable life cycle costs.

The Cost Calculator tool is available in E/One's Design Center.
