Innovative Underground Infrastructure Services for California Municipalities, Agencies, and Utilities
In California, maintaining the health of sewer systems is vital for public safety and infrastructure longevity.
Duke's is a leading provider of essential sewer solutions, ensuring the underground infrastructure in California's largest cities receives the expert maintenance it demands. Our comprehensive services, encompassing both preventative and reparative measures, are readily available throughout major California metropolitan areas, including Los Angeles, San Diego, San Jose, San Francisco, Fresno, Sacramento, Long Beach, Oakland, Bakersfield, and Anaheim. The diverse and unique urban landscapes across California necessitate tailored approaches: Los Angeles, as California's most populous city, often requires frequent sewer inspections and cleanings to manage its extensive network, while cities with aging infrastructure, such as Oakland, frequently encounter the persistent challenge of root intrusions within underground utility pipes.
Leveraging advanced technologies like CCTV sewer inspections, manhole assessments, and efficient CIPP spot repairs for pipeline rehabilitation, Duke's ensures the regular and effective upkeep of pipes, sewer lines, and other critical utilities. With decades of specialized experience in the sewer industry, coupled with cutting-edge technological innovations and a highly skilled team of professionals, Duke's delivers the best solutions for California municipalities to cost-effectively maintain the health of their underground infrastructure and proactively avoid costly emergencies. Our tailored solutions are designed to help California cities stay ahead of maintenance challenges, significantly reduce operational costs, and safeguard public health and the environment.




Available Services for California
While Duke's remains the leader in chemical root control, we also offer a variety of other services to help prolong the life of underground infrastructure. These include critical inspection services, cleaning, testing, mapping, and more—all working to benefit the cities and citizens of California.
Roots can cause big, expensive problems for pipes and the best course of action is always preventative care. You need a team that can implement a root control program that minimizes damage, disruption, and costs while preventing roots from quick regrowth to cause problems yet again. Duke's can provide a chemical/herbicide solution to problematic roots throughout cities where we operate in Michigan.
A comprehensive approach to pipeline inspection is the best way to ensure that potentially expensive and disastrous problems aren’t brewing in a city’s pipe system. For the municipalities in Michigan where we operate, Duke’s can apply multiple inspection techniques to obtain a thoroughly accurate assessment of a pipeline’s condition and ensure nothing gets overlooked.
Using 360-degree camera technology, Duke’s can provide manhole inspection services to cities in Michigan and ensure up-to-date, accurate information regarding the integrity and functionality of wastewater systems and infrastructure. Prevent costly treatment after the fact by addressing potential inflow and infiltration issues before they happen with regular inspections.
A common method for detecting leaks or cracks in sewer system pipes, Duke’s performs smoke & dye testing with non-toxic smoke and documents results with GPS. It’s a simple but highly effective method of assessing the overall integrity of the wastewater infrastructure that Duke’s offers to cities throughout Michigan.
Regular CCTV inspections and cleaning are essential tools for identifying weaknesses and ensuring the reliability of sewer lines. Duke’s uses advanced camera systems to visually assess the interior condition of sewer pipes and detect cracks or structural defects, root intrusions, blockages, and signs of inflow and infiltration. Enhance your sewer system’s reliability with expert CCTV inspections and cleaning services throughout Michigan.
Traditional models may only detect inflow and infiltration (I&I) over large areas, but Duke’s employs advanced micro-detection technologies and algorithms to pinpoint the specific line segments causing excess I&I within a basin, down to the street level, improving both speed and precision.

Inspections of entire collection systems are crucial in preventing sewer backups and minimizing potential (and expensive) damage, but these inspections can be expensive themselves. Acoustic pipeline inspections are faster and more cost effective solutions we offer in cities throughout Michigan, ensuring efficient and effective results.
Municipalities in Michigan can mitigate risk, service disruptions, expensive repairs, and safety problems by inspecting for current cross-bores and implementing ways to prevent future ones. Duke’s provides cross-bore inspection services that include pre- and post-inspection data to ensure you have all the necessary knowledge and cross-bores don’t become a costly problem.
