Rhino Engineering provides multidisciplinary transportation engineering and infrastructure support services across multiple jurisdictions, supporting projects involving highways, arterial and local roadways, interchanges, bridges, rail and transit corridors, and long-range transportation planning. Our services include preparation of engineering drawings and traffic control plans in accordance with MUTCD standards, along with transportation-focused environmental and infrastructure analyses for municipal, regional, state, and federal agencies to ensure regulatory compliance and constructible, defensible design deliverables.
Our work has been performed in coordination with agencies and utilities across diverse geographic regions, including Maryland (MDOT and DC Water programs), California, Colorado, Georgia, Puerto Rico, New Jersey, and Pennsylvania. This multi-jurisdictional experience enables Rhino Engineering to navigate varying regulatory frameworks, permitting requirements, and traffic control standards while delivering consistent, technically sound plans and analyses tailored to each transportation network and infrastructure program.

REHABILITATION RECOMMENDATIONS

REHABILITATION RECOMMENDATIONS

July 29, 2024

Trenchless methods offer a versatile solution for rehabilitating existing pipelines under diverse conditions. These techniques are especially advantageous in urban settings, where traditional construction methods can severely disrupt business operations, residential areas, and both vehicular and pedestrian traffic.

 Additionally, the presence of other underground utilities and existing infrastructure poses significant challenges for conventional excavation and replacement approaches. Consequently, trenchless techniques are frequently employed in such scenarios. In general, trenchless sewer rehabilitation methods necessitate less installation time, and consequently, reduced pumping time compared to traditional excavation and replacement methods.

We have the following experience in the design and execution of the following methods (inside and outside the US):

CIPP Cured-in-Place Pipe: A seamless rehabilitation method using resin-impregnated liners, CIPP offers a joint-free
solution for pipes.
Sliplining: This approach involves inserting a smaller pipe into a larger one and can be effective for structural
rehabilitation.
PE or PVC Spiral Wrapping: This technique creates a liner within the pipe, using interlocking strips of PVC or HDPE. Its
adaptability to various geometries makes it versatile.
Folding and formed liner: Ideal for smaller pipes, this method uses flattened or folded PVC or HDPE pipes. It offers a
balanced approach between ease of installation and impact on capacity.
Geopolymer Liner: A high-strength mortar, geopolymer is applied as a liner. Its corrosion resistance and durability
characteristics make it a powerful solution.
Epoxy and polyurethane coating: Offering a range of applications, epoxy coatings provide structural or non-structural
solutions with high corrosion resistance.
Pipe bursting: Although technically a replacement method, pipe bursting may be considered due to its
trenchless approach. Its suitability depends on factors such as alignment and proximity to the utility.

As part of our engineering consulting services, Rhino Engineering develops comprehensive rehabilitation and capital improvement recommendations that incorporate trenchless technologies as a primary strategy for restoring structural integrity and hydraulic performance of existing pipelines. These recommendations are formulated within the context of our custom asset management and rehabilitation planning programs, which integrate detailed condition assessment data, hydraulic capacity analyses, and LOF × COF risk prioritization to optimize project sequencing, constructability, and long-term system reliability; particularly within densely developed utility corridors where open-cut replacement is constrained by traffic, adjacent infrastructure, and service continuity requirements.

Our engineering recommendations are further supported through the preparation of sewer and stormwater master plans and maintenance and operations scheduling frameworks that establish performance-based rehabilitation strategies aligned with regulatory requirements and capital planning objectives. We incorporate environmental stewardship and sustainability principles into all phases of planning and design, emphasizing ethical engineering practices that minimize ecological disturbance, reduce carbon-intensive construction impacts, and promote long-term resource efficiency. Within this framework, trenchless methods are evaluated and recommended based on asset criticality, deterioration modeling, constructability constraints, and lifecycle cost considerations. This planning-driven engineering approach enables targeted, minimally disruptive rehabilitation solutions that reduce installation duration, bypass pumping demands, and surface impacts while enhancing lifecycle cost efficiency, environmental responsibility, and long-term infrastructure resilience.
