Our services

Designed for municipalities, engineering firms, and commercial clients

Using our state-of-the-art, steerable robotic crawler (an innovation not standard in the industry) we perform detailed storm line and sewer camera inspections.

Our technology allows us to identify cracks, root intrusions, and infiltration points with pinpoint accuracy. These inspections provide you with high-quality video recordings and defect reports, enabling proactive maintenance and long-term cost savings.

What sets us apart:

Our cutting-edge equipment is designed to handle even the most challenging sewer line cleaning jobs.

From grease buildup and root intrusion to gravel and construction debris, we restore your sewer lines to optimal functionality. Our specialized nozzles and vacuum systems ensure thorough cleaning while protecting the integrity of your pipes.

Why choose UIS:

Roots are a leading cause of sewer blockages, and UIS offers multiple solutions to address this issue effectively.

Our hydraulic cutting tools minimize damage to fragile pipes, while our mechanical chain cutters handle larger-diameter pipes with ease. We educate clients on the best approach to protect their systems.

How we add value:

With our advanced 360-degree camera and lighting system, we inspect manholes safely and efficiently.

This technology reduces the need for human entry, minimizes traffic disruptions, and provides precise measurements for structural assessments.

What makes UIS different:

Our smoke testing process uses specialized equipment to quickly and efficiently locate leaks in sewer systems.

By detecting breaches early, we help municipalities avoid EPA fines, consent decrees, and costly overflows. All findings are logged into GIS maps with precise GPS coordinates for actionable insights.

The UIS advantage:

UIS provides GIS-based sewer mapping, creating digital blueprints of sewer systems with precise latitude, longitude, and GPS points.

Whether you’re updating outdated records or starting from scratch, our mapping services are cost-effective and indispensable for municipalities and engineering firms.

Why sewer mapping matters:

Tap cutting ensures that service lines tying into sewer mains do not protrude and cause blockages. Using the same advanced mechanical cutters as in root removal, we shave down any protruding materials, making the pipe interior flush and functional.

For lining contractors, we prepare pipes by sanding and smoothing their interiors, ensuring they’re in the best condition for rehabilitation coatings. After lining, we provide post-work inspections, debris cleanup, and ensure all connections are clear and precise to avoid disruptions.

Why choose UIS for tap cutting and lining preparation:

Our dye testing service identifies active and inactive sewer connections, particularly in older systems where storm drains and sewers were once combined.

By flushing dye into nearby buildings, we locate lines that need to remain open and those that can be capped or coated. This process provides clear data for engineers while UIS handles cleanup to ensure minimal disruption.

The UIS advantage in dye testing:

Hydro excavating is a safe, non-invasive way to dig around sensitive infrastructure like water lines, sewer pipes, or fiber optic cables.

High-pressure water breaks up the ground to create a mud slurry, which is then vacuumed away without mechanical force. This reduces the risk of damaging underground utilities, making it ideal for municipalities and contractors working in densely packed areas.

Benefits of UIS hydro excavating:

Lateral launching combines the power of a crawler with a push camera, enabling us to inspect service lines that are difficult to access. This service is especially critical for gas companies using directional drilling, as it ensures no cross bores are present.

By marking and locating any issues, UIS helps clients avoid costly damage and environmental hazards. We also offer HOA and property management partnerships to provide efficient inspections across multiple homes.

Why UIS is the right choice for lateral launching:

We provide comprehensive coding services for sewer systems, including manholes, pipelines, and lateral connections.

Certified to NASSCO standards, our team identifies defects, logs them into detailed reports, and ensures municipalities meet compliance standards. With cutting-edge AI technology, we streamline coding processes for faster, more accurate results, offering both fieldwork and office-based analysis for maximum flexibility.

The UIS difference in coding services:

Using radio frequency technology, our sonde locating service identifies underground manholes, pipes, and service lines with high precision.

Whether locating buried access points or pinpointing problems, this service is essential for mapping, repairs, and demolitions. Sonde locating integrates seamlessly with other UIS services, such as lateral launching and GIS mapping, providing accurate and actionable data.

Why sonde locating is a critical UIS service:

UIS offers professional traffic control solutions to ensure the safety of both workers and the public.

From flaggers and signage to follow-behind vehicles, we manage traffic efficiently for municipalities, contractors, and engineering firms. Our expertise extends to high-traffic areas like interstates, and our flexible approach means we can scale services to meet project needs.

How UIS stands out in traffic control:

In the aftermath of hurricanes, floods, or other natural disasters, UIS provides critical sewer system maintenance and storm drain cleanup.

Our team has extensive experience, including work with FEMA after Hurricane Katrina, clearing debris, and reassessing damaged infrastructure. We also offer emergency response services, including erosion inspection, flow monitoring, and road cleanup to restore systems quickly and effectively.

The UIS natural disaster advantage:

Our ditching service removes overgrown grass, debris, and sediment blocking storm drainage systems.

By excavating and restoring drainage ditches, we ensure stormwater flows properly, reducing the risk of flooding and damage. This service often includes catch basin cleaning for a comprehensive solution to surface water management challenges.

Why UIS excels in ditching services:

Our quality assurance ensures visible results for typically-invisible underground systems

What can UIS accomplish in a day?
Our efficient team can inspect or clean hundreds of feet of pipe daily, depending on the complexity and condition of the system.

Our equipment accommodates pipes ranging from 6 inches to 36 inches, including sewer and storm lines.

While our focus is municipal and commercial systems, we work with HOAs and property management companies for residential sewer line inspections, maintenance, and cleaning.
We know that sewer systems and storm lines are typically “invisible,” so we work to deliver concrete visuals so that you can see the results of our services. We provide high-quality video recordings, defect reports, and GIS mapping data to help you maintain and manage your system.
Addressing issues like cracks, infiltration, or root intrusion early prevents costly repairs, overflows, environmental damage, and EPA fines. Proactive maintenance is much more cost-effective than reactive repairs in the face of significant system damage or neglect.
We prioritize emergency requests and can deploy teams quickly to prevent overflows or resolve critical issues.
We strive to address all needs within one week.
Commercial sewer cleaning involves servicing larger, more complex systems than those typically found in residential properties. These systems often handle higher volumes of waste and require specialized equipment to remove grease, debris, and roots. For municipalities and commercial organizations, regular sewer cleaning is critical to preventing overflows, maintaining environmental compliance, and ensuring uninterrupted operations.
A UIS sewer camera inspection uses advanced robotic crawlers equipped with steerable cameras to capture detailed footage inside sewer lines. The crawler is inserted into the pipe through a manhole and navigates the system while recording video and logging GPS data. This technology, along with operator expertise, is used to identify structural defects, root intrusions, and infiltration points, providing municipalities with actionable insights for proactive maintenance and repair.
Typically, no. Occasionally, we will reroute traffic patterns, which may cause a slight inconvenience. We work diligently to prevent long-term traffic backups. For smoke testing, we provide 36-48 hours’ notice to surrounding homes and businesses to minimize inconvenience.
