Comprehensive inspections and experienced teams.

Hydromax USA leads the way in comprehensive manhole inspection services, leveraging decades of experience to help utilities optimize their wastewater infrastructure. Our proactive approach includes detecting Inflow & Infiltration sources, assessing structural integrity, ensuring accurate GPS mapping, and verifying sewer system records. By implementing our tailored inspection programs, utilities can reduce operation costs, prevent critical failures, and gain meaningful, data-driven insights for optimal asset management.

Assessing structure, verifying mapping, and detecting I/I sources.

By implementing a proactive manhole inspection program, utilities can significantly reduce operation and maintenance costs. Routine inspections become a preventive measure that identifies defects and safety concerns before they escalate into critical asset failures.

Our manhole inspection programs serve multiple crucial purposes, providing valuable insights into your wastewater system:

  • Inflow & infiltration detection: We perform inspections to identify sources of Inflow & Infiltration (I/I). This helps mitigate excessive water entering the sewer system, a key factor in system efficiency and controlling treatment costs.
  • Structural assessment: We assess the structural condition of manholes, ensuring their integrity and longevity. Identifying any structural defects is a vital part of this assessment.
  • Accurate GPS location: Utilizing GPS technology, we pinpoint manhole locations with sub-meter accuracy. This precision ensures that each manhole is correctly identified and that there is no confusion in reading maps.
  • Verification and correction: Our inspections help verify or correct existing sewer maps, ensuring that your records are accurate and up to date.

Inspections that optimize your programs.

Sewer manhole inspections serve as a critical tool for sewer utilities to optimize their operations. Costly repairs, rehabilitation, or replacements of manholes can significantly strain utility budgets. The repercussions of manhole asset failures can disrupt sewer systems, leading to sewage leaks and overflows that not only pose environmental and health hazards but also result in costly emergency responses.

Our manhole inspection programs equip our field crews with a comprehensive set of capabilities, streamlining the inspection process. Our tools empower teams to perform routine manhole inspections efficiently, gain in-depth insights into manhole conditions, record inspection data in the field, and manage inspection activities seamlessly. With all stakeholders having easy access to inspection information, utilities can make informed decisions and protect their assets, reducing the risk of costly emergencies and ensuring the continued proper function of their sewer systems.
