Improve Sewer and Storm System GIS Data Precision with AMP Pipeline Mapping

When it comes to managing underground infrastructure assets, many municipalities and utilities rely on drawings that no longer reflect what actually exists underground. Over the years, pipes shift, repairs are made, and records become outdated. When pipe location, slope, or elevation is uncertain, it becomes harder to plan inspections, locate defects, and prioritize rehabilitation needs cost-effectively.
At Compliance EnviroSystems (CES), we use advanced technologies to improve the accuracy of sewer and/or stormdrain system data. One of the most powerful tools available today is the Accurate Mapping Probe, or AMP.
AMP provides highly precise pipeline location and elevation data that facilitates more accurate GIS mapping, improves CCTV inspection accuracy, and helps utilities better understand their underground infrastructure.
With more than 30 years of evaluation experience and over 110 million linear feet of storm system and sanitary sewer system infrastructure inspected, CES uses tools like AMP to give clients the reliable data they need to make informed decisions.
What Is AMP Pipeline Mapping?
The Accurate Mapping Probe (AMP) is an autonomous pipe mapping system that measures the precise location and geometry of underground pipes.
As the probe travels through the pipes, it collects highly accurate positional data. This allows engineers, utility providers, municipalities, and contractors to confirm pipe alignment and detect issues or pipe defects that may impact system performance.
AMP can help identify:
- Pipe sags that restrict flow
- Misaligned joints
- Changes in pipe slope or alignment
- Locations of structural defects
- Any inconsistencies in pipe design
This level of precision provides a clearer understanding of how a storm system or sanitary sewer system is functioning below the surface.
Why Accurate GIS Mapping Matters
Many utility, engineering, municipal, and contractor clients are working with incomplete or outdated infrastructure records. Without reliable data, it becomes difficult to locate pipes, verify pipe depth, or understand how defects impact the system.
AMP helps improve GIS mapping by providing precise XYZ pipeline location data that can confirm or update existing records.
When combined with other inspection methods such as CCTV inspection and SSES investigations, this data allows utilities to:
- Improve the accuracy of GIS mapping
- Pinpoint the exact location of pipe defects
- Plan inspections more efficiently
- Prioritize rehabilitation projects with confidence
- Reduce unnecessary cleaning or repair costs
Better Data Leads to Better Infrastructure Decisions
Reliable infrastructure management starts with reliable data.
AMP mapping provides CES clients with a clearer understanding of pipe alignment, slope, and location within their stormwater system or sanitary sewer system. This allows municipalities and engineers to make smarter decisions about maintenance, inspections, and rehabilitation.
At CES, our goal is simple. Deliver accurate data that helps clients protect and manage their underground infrastructure for the long term.
If your system needs more precise mapping data, CES can help you strengthen your GIS mapping and better understand the true condition of your pipes. To learn more or schedule a presentation,
