Purpose and Scope

Contingency planning is critical to successful water, sewer, and stormwater infrastructure operations. For Hinterland Group, contingency planning encompasses temporary bypass systems, overflow mitigation strategies, and traffic control solutions. These measures ensure uninterrupted service, environmental protection, and public safety during planned rehabilitation, emergency repairs, and capital improvement projects.

This document outlines Hinterland Group's approach, capabilities, benefits, and real-world applications related to contingency planning, with a focus on:

• Temporary bypass pumping and piping systems

• Overflow mitigation practices

• Comprehensive traffic control during construction or emergencies

More about Hinterland Group’s Services

Temporary Bypass Systems

Overview

Bypass systems allow pipeline, manhole, or lift station work while maintaining continuous service. This prevents service interruptions, environmental harm, and regulatory violations resulting from untreated discharges or overflows.

Features and Capabilities

• Precise Engineering: Custom bypass plans are developed based on hydraulic modeling, site constraints, and client needs.

• Equipment Fleet:

• High-capacity diesel and electric-powered pumps

• Redundant pump setups for reliability

• UV-rated, leak-resistant HDPE bypass piping

• Flow meters and telemetry for real-time monitoring

• In-house Deployment: Hinterland Group’s trained crews mobilize and operate all equipment, ensuring full accountability and rapid response.

• 24/7 Emergency Readiness: Guaranteed 15-minute callback and rapid on-site response to critical events (source).

Use Cases

• Planned Sewer/Lift Station Rehabilitation: Enables work on live mains, lift stations, or force mains without affecting upstream customers or causing backups.

• Emergency Main Breaks: Immediate deployment allows continued flow until repairs complete, as demonstrated in hurricane/flood events (see testimonials).

Benefits

• Eliminates or drastically reduces service interruptions

• Prevents regulatory violations from unauthorized discharges

• Supports rapid project schedules and client business continuity

Overflow Mitigation

Overview

Unplanned surcharges, pipe failures, or heavy rainfall pose risks of sanitary sewer overflows (SSOs) and stormwater system excesses. Hinterland Group mitigates these risks before, during, and after rehabilitation activities.

Tactics and Practices

• Rapid Isolation and Pump-out: Emergency pump crews swiftly redirect flows to secondary containment or alternate lines.

• Temporary Storage: Portable tanks or lagoons hold excess flow until restoration.

• Proactive Inspection: Pre-project cleaning, CCTV, and root/debris removal minimize overflow triggers.

• Wet Weather Readiness: Equipment staged for rapid response during expected rain events.

• Regulatory Reporting: Compliance with local, DEP, and EPA notification requirements (example).

Benefits

• Limits risk of environmental damage, fines, and community health impacts

• Supports customer regulatory compliance

• Maintains public and stakeholder trust

Traffic Control During Construction

Overview

Major water, sewer, and stormwater projects—especially in urban, commercial, or high-traffic settings—require diligent traffic control for public and worker safety. Hinterland Group integrates advanced traffic management with its civil works.

Capabilities

• Permitted Lane Closures: Coordination and permitting with city/county agencies for planned closures, detours, or temporary signals

• Certified Flagging Crews: On-site personnel trained in MUTCD and DOT-compliant flagging operations

• Signage & Barricades: Deployment of highly visible, regulatory-standard signs, cones, and barriers

• Pedestrian Protection: Fencing, walkways, and ADA-compliant detours when projects intersect sidewalks or points of access

• Stakeholder Communication: Advance notification and coordination with local businesses, residents, and emergency services

Use Cases

• Deep pipeline or manhole excavations in roadways

• Bypass piping crossing driveways or intersections

• Neighborhood and commercial area project sites

• Hurricane/flooding response zones with heavy traffic

Benefits

• Reduces accident and liability risk

• Maintains community access and business continuity

• Meets municipal, county, and DOT safety regulations

Common Questions (FAQ)

When is a temporary bypass system required?

A temporary bypass system is typically required during any repair, maintenance, or replacement project that disrupts the flow in an active water or sewer pipeline, pump station, or force main. It is crucial for planned rehabilitation and unplanned breaks or blockages.

How does Hinterland Group ensure bypass reliability?

Through dual/redundant pumps, real-time flow monitoring, automatic alarms, and on-site standby crews, Hinterland Group maximizes reliability and minimizes failure risk. Equipment selection matches project flows and criticality, drawing on field experience from hundreds of bypass operations.

What strategies are used to prevent overflows?

• Proactive pipe cleaning and debris removal

• Pre-construction risk analysis

• Bypass system deployment and monitoring

• Regular inspection and rapid deployment in weather events

• Effective coordination with client and local environmental agencies

How is traffic safety ensured during pipeline work?

• Traffic control plans are designed to DOT/local standards and permitted as required

• Trained in-house flaggers and vehicle spotters maintain safe flows

• Proactive community outreach and coordination with first responders

• Use of physical barriers, signs, cones, and digital message boards as site conditions demand

Who benefits from these contingency planning services?

• Municipal utility agencies (e.g., Palm Beach County, Manatee County): for critical infrastructure and service continuity

• Commercial/retail districts: to guard business operations from disruption

• Property management/industrial sites: for minimization of tenant and production impacts

What evidence exists of Hinterland Group’s emergency response?

Past projects such as the West Palm Beach flood emergency and critical bypass deployments for lift station outages demonstrate Hinterland Group’s expertise and readiness (see case studies).
