Drainage Solutions in South Louisiana

Standing water in South Louisiana yards typically results from one or more of the following: low spots or depressions where water collects, inadequate slope or grade directing water toward the house or into the yard, compacted clay soil that sheds rainfall faster than it can absorb it, insufficient or blocked drainage infrastructure, and high water table conditions common across much of the region. Identifying the specific cause is the first step — the wrong solution applied to the wrong cause produces no improvement and wastes money.

A French drain is a gravel-filled trench containing a perforated pipe that collects water from saturated soil or surface runoff and channels it to a discharge point — typically the street curb, a drainage ditch, or a dry well. Water enters the trench through the gravel and perforated pipe, then flows downhill to the outlet. French drains are one of the most versatile and effective solutions for chronic wet areas in South Louisiana yards when properly designed for the volume of water involved.

Permit requirements vary by municipality and parish across South Louisiana. Most simple grading work on private property does not require a permit. However, connections to public drainage infrastructure, significant earthwork, work within drainage servitudes or rights-of-way, and projects near wetland boundaries may require permits or approvals from local drainage authorities. We're familiar with requirements across our service area and will identify any permit needs during the assessment phase before any work begins.

Drainage project costs vary widely based on the length of the drain, the depth of installation, the outlet location, and site accessibility. A simple French drain to address a single wet area can be completed for a few hundred dollars, while a comprehensive drainage system involving multiple catch basins, extended pipe runs, and significant grading can cost several thousand. We provide a detailed, itemized written estimate after a thorough site assessment — every project is different, and we don't use one-size-fits-all pricing.

Most residential French drain and drainage improvement projects are completed in one to two days. More complex projects involving multiple drainage structures, significant grading, or difficult access may take three to five days. We schedule drainage work during dry weather windows whenever possible, and we leave your property stabilized and protected from erosion at the end of each work day. We'll provide a realistic completion timeline in your estimate before the project begins.

A catch basin is an in-ground box with a grated top that collects surface water and directs it into a pipe system that carries it to a discharge point. Catch basins are used when surface runoff volume is too high for a simple French drain to handle, in low spots that collect water from large surrounding areas, and at downspout outlets when traditional downspout extensions aren't sufficient. They're commonly installed in South Louisiana driveways, behind garages, and in yard low spots that collect runoff from neighboring properties.

In some cases, yes. If the problem is a simple low spot or incorrect slope directing water toward the house or into a depression, re-grading the area to create positive drainage away from structures and toward a natural outlet can be sufficient without installing pipe systems. However, in many South Louisiana situations — where the water table is high, soil is compacted clay, or surrounding grade doesn't provide a natural outlet — grading alone moves the water but doesn't give it anywhere to go. A thorough site assessment is necessary to determine the right solution.

The most effective preparation for South Louisiana's heavy rain season involves addressing known drainage problems before they arrive rather than managing water in a crisis. This means installing or improving French drains in chronically wet areas, extending downspouts away from the foundation, re-grading low spots, clearing any blocked or silted drainage structures, and ensuring all pipe outlets and drainage connections are functioning freely. We offer pre-wet-season drainage assessments for property owners who want to address vulnerabilities proactively before the next major rain event.
