R3M and its employees offer our clients Large Project Expertise through a personalized and local approach. We provide analysis, design, permitting, and construction phase services for Municipalities for a wide range of engineering disciplines across wastewater pumping and treatment, biosolids management, and pipeline design, construction, and maintenance. Listed below are some of the foremost ongoing or completed projects that R3M Engineering has provided its services to.

Flood Mitigation and Permanent Restoration of Sayreville Pump Station

Middlesex County Utilities Authority (MCUA) Sayreville, NJ

  • ACEC New Jersey 2022 Engineering Excellence Honor Award Recipient
  • $68M project to permanently restore and mitigate peak 340 MGD pump station compromised during Hurricane Sandy.
  • R3M led design of complex structural, mechanical, electrical, and instrumentation systems, including:
    • Perimeter flood wall up to 500-year storm level plus storm surge.
    • Stormwater pumping station & controlled/automatic flood gates to isolate the pump station during flood conditions.
    • 10 MW standby power facility including three diesel and one natural gas gensets.
    • Relocation of the main electrical substation.
    • Installation of a knife gate valves on four (4) influent main truck sewers up to 132-inch in size.
    • Replacement of ten (10) 800-1,000 HP pump motors, as well as piping, valves, controls, and instrumentation.
  • R3M coordinated with the Federal Emergency Management Agency (FEMA) and the New Jersey Environmental Infrastructure Trust (NJEIT) to fund the project.
  • Ribbon Cutting Ceremony Announcement
  • Ribbon Cutting Ceremony Recap

Hurricane Recovery Program at the Sayreville Pump Station

Middlesex County Utilities Authority (MCUA), Sayreville, NJ

  • MCUA’s Sayreville Pump Station was inundated with 4 feet of water following Hurricane Sandy.
  • R3M mobilized resources to provide 24/7 emergency response along with construction contractors to be able to stabilize the pump station.
  • R3M worked with MCUA staff to restart the disabled pump station, initially using temporary bypass pumping systems capable of 70 MGD within 10 days of the event. Ultimately restoring the existing pumps and motors and switchgear to its 300 MGD capacity.
  • R3M worked with USEPA, NJDEP and US Army Corp representatives to develop unique temporary wet weather overflow systems to prevent further
    flooding of pump station during emergency restoration activities.

Superstorm Sandy Recovery Program at the Bayshore Regional Sewerage Authority

  • R3M coordinated with BRSA staff and FEMA representatives to develop Project Worksheets (PW) to define temporary and permanent restoration at each of the 23 separate facilities and structures within the BRSA Plant. R3M developed work scopes and cost estimates for each PW.
  • R3M worked with FEMA consultants retained by the BRSA, evaluated mitigation alternatives for the impacted facilities and developed Hazard Mitigation Plan Proposals for each of the Authority’s major pump stations, process systems and its two sludge incinerators.
  • R3M worked closely with BRSA to secure SAIL Loan funding through the NJEIT to support the restoration and mitigation work under 5 separate construction contracts.

Pipeline Assessments; Bayshore Regional Sewerage Authority

  • R3M developed a three-phase plan to improve the condition of Bayshore Regional Sewerage Authority’s collection system.
  • Coordinated remote pipeline inspections using PipeDiver and SmartBall technology.
  • Validated the “pipes of concern” through non-destructive testing (NDT).
  • Designed and observed repairs and replacements to “pipes of concern” and inoperable mechanical equipment along pipelines.
  • R3M will soon develop a Pipeline Management Program for future long-term pipeline monitoring and maintenance.

Structural Repairs to the Klockner Pump Station; Hamilton Township Department of Water Pollution Control

  • R3M inspected and evaluated chloride penetration and contamination within major pump station.
  • Design of emergency structural repairs to concrete floor and beams.
  • Hidden damage to the steel reinforced concrete structure was discovered and overcome.
  • R3M sequenced and staged construction to maintain the integrity of the structure.
  • The structural rehabilitation was completed with no impact to operations at the pump station.

Crossroads Interceptor Sewer; Old Bridge Municipal Utilities Authority

  • R3M provided evaluations and design for a regional interceptor sewer to serve the proposed Crossroads Redevelopment Area.
  • Design of approximately 9,500 linear feet of 8-inch, 12-inch, and 15-inch sanitary sewer pipe, including two (2) stream crossings, alignment through approximately 0.49 acres of freshwater wetlands, and two (2) highway crossings.
  • Small-bore microtunneling methods employed minimized environmental impacts on streams and wetlands areas.

Millstone Pump Station – Odor Control System

  • R3M provided a feasibility study, then designed and provided engineering services for odor control system improvements for a pump station in Princeton, NJ
  • The system improvements included:
    • Radial flow activated carbon adsorber with demister and centrifugal fan
    • High-plume fan
    • New fiberglass-reinforced plastic ventilation ductwork
