Leak Surveys in Wilmington

Find Hidden Leaks Without Unnecessary Damage

A leak survey examines multiple access points or areas within a distribution network for signs of hidden leakage. American Leak Detection of South Jersey & Delaware provides leak detection for residential, commercial, and municipal properties in Wilmington, Delaware and New Castle County. Backed by more than 40 years of industry experience, we use non-invasive methods to investigate:

Hidden water leaks
Sewer and drain leaks
Pipe leaks
Wall leaks

This broader assessment differs from a single-property service call focused on one suspected leak or building system. Leak surveys can help municipal water utilities, water districts, property managers, facility operators, and property owners narrow suspected water loss before making repair decisions. This work is especially relevant where Wilmington Water provides water and wastewater service to more than 450,000 people each day through over 420 miles of mains.

Leak Survey Capabilities for Wilmington Properties & Utilities

Our commercial and municipal work focuses on confirming and narrowing a leak’s location rather than providing general plumbing or repair services. Technicians complete rigorous training for situations ranging from pressurized pipe leaks inside finished walls to slow drain leaks beneath concrete floors. This preparation supports investigations across municipal infrastructure, commercial facilities, managed properties, and individual buildings.

Acoustic leak detection uses sensitive listening equipment to identify the sound of water escaping from a pressurized pipe. Technicians trace that sound from the surface to narrow its position without demolition. Locating the suspected source before excavation or demolition helps the responsible parties define the area requiring further action.

Leak surveys can also support water-loss reduction efforts. Non-revenue water enters a distribution network but isn’t billed. It includes real losses from leaks and breaks, apparent losses, and authorized consumption that isn’t billed. A 2020 Delaware statewide needs assessment recommended greater emphasis on system auditing and loss reduction.

What to Expect During a Leak Survey

Commercial and municipal investigations may begin with a review of observed symptoms and coordination of site access. We identify the areas and access points that require investigation, then apply locating methods suited to the site conditions. Our technicians use the detected evidence to narrow the suspected leak location.

We communicate the findings to the designated property contact and responsible repair party. They can use the confirmed or narrowed location to determine the repair scope and subsequent work. Detection findings alone don’t establish that a later repair, alteration, permit, or inspection satisfies applicable requirements.

Our technicians arrive on time, complete the work within the stated time frame, and leave the property clean. If the detection scope or timing changes while work is underway, we communicate clearly with the appropriate contact.

Request a Leak Survey with Upfront Pricing

To begin the conversation, provide the property or utility location, observed symptoms, and relevant site-access considerations. Our Know Before You Go approach provides upfront pricing before work begins, so the responsible stakeholder understands the cost before authorizing the survey.

How Acoustic Leak Surveys Narrow the Search

An acoustic survey may involve listening at water-distribution appurtenances, the components that provide access to or control the network. Hydrants, valves, and services can be sounded at intervals with leak-noise amplification equipment. Technicians evaluate detected noise to identify areas requiring closer investigation.

Acoustic survey methods may include:

Leak-noise correlation: A leak-noise correlator analyzes sound detected at separate points on a pressurized pipe to narrow the suspected leak location.
Surface listening: A ground microphone allows the technician to listen from the surface near a suspected location.
Targeted pinpointing: Correlation results and ground-microphone readings guide closer investigation of suspect leak noises.

When to Consider a Leak Survey

Municipal utilities and water districts can use survey findings to investigate potential real water losses within distribution systems. The results can help operators prioritize further investigation before deciding how repairs should proceed. A survey is an investigative step, not a commitment to a particular repair method.

Property managers and commercial facility operators may request a survey when unexplained water use or concealed leakage requires investigation across a site. A narrowed location can support access coordination and communication with the party responsible for repairs. Property owners can also seek detection for hidden water, sewer, drain, pipe, or wall leaks.

Repair, Permit & Inspection Responsibilities

Leak detection identifies or narrows a suspected source. Our findings don’t determine whether later repair, alteration, permitting, or inspection work complies with Wilmington or Delaware requirements. The licensed or otherwise authorized party performing that work should verify the obligations that currently apply.

Delaware uses the International Plumbing Code as its statewide base plumbing code, with political subdivisions enforcing the code as adopted or modified by the state. The Delaware Division of Public Health lists the 2021 International Plumbing Code as the current adopted edition. Requirements can depend on the nature and location of the work, so the responsible party must evaluate the planned repair rather than treat detection findings as code approval.

Separate public programs may also affect utility decisions. The City of Wilmington is conducting a citywide water service line inventory and survey under the Environmental Protection Agency’s revised Lead and Copper Rule to identify lead service lines on private property. That inventory serves a different purpose from acoustic leak detection and doesn’t change the responsibility for verifying repair, permit, and inspection requirements.
