Ponds & Retention Basins
Engineered pond excavation, shaping, and water-management structures built for Louisiana’s terrain.
Besco Construction specializes in building ponds and retention basins that not only enhance the appearance of your property, but also provide critical drainage and water-management benefits.
From scenic residential ponds to engineered retention systems, we excavate, shape, grade, and stabilize soil for long-term performance. Every pond is built with Louisiana’s unique soil, water table, and rainfall conditions in mind.
​
Whether you're improving drainage, adding a water feature, or managing runoff for a new development, we create ponds that work — and hold up over time.

Why Ponds & Retention Basins Matter
Properly constructed ponds and basins help control:
​
Heavy rainfall runoff
Erosion & soil loss
Standing water on property
Flooding in low areas
Surface drainage for homes or buildings
Water management in subdivisions
Aesthetic property improvement
In South Louisiana, ponds and retention structures are not optional — they’re essential for protecting your land and controlling water volume.
​
Our Pond & Basin Construction Process
1. Elevation & Flow Assessment
We evaluate the natural flow of water, soil type, elevation, and required pond size.
​
2. Excavation & Shaping
Komatsu excavators and dozers cut and shape the basin, cleanly forming the required contours and depths. ​
​
3. Building Side Slopes & Safety Banks
We create stable, properly angled banks to prevent erosion and collapse.
​
4. Drainage Integration
We install spillways, outflow structures, and overflow paths to ensure safe water movement.
​
5. Soil Stabilization
We compact, grade, and stabilize slopes to prevent washouts and long-term erosion.
​
6. Finishing & Final Grading
We clean edges, shape the surrounding area, and ensure positive drainage around the pond.
