Catch Basins, Grading & Swales: Fixing Standing Water the Right Way

French drains aren't the only tool. Sometimes the fix for a soggy yard is smart grading, a catch basin, or a swale — often working together.

Not every drainage problem in Central Florida requires a full French drain system. For surface water pooling on patios, driveways, and low lawn areas, catch basins, re-grading, and swales are often the most effective and cost-efficient solutions. These tools work alone or combined with French drains for complete protection.

Catch Basins

A catch basin is a grated box set into a low point that collects surface water and channels it into an underground pipe. Perfect for patios, driveways and the spots where water always seems to gather. In sandy Florida soil, proper installation prevents clogging.

Grading & Swales

Sometimes the real problem is that the ground slopes the wrong way. Re-grading and shaping gentle swales redirect water away from the house and toward a controlled discharge — no digging a full trench required. This is often the first step in any yard drainage project.

The Right Combination for Your Yard

  • Catch basins for concentrated surface pooling
  • Grading and swales to guide sheet runoff
  • A French drain where groundwater is the issue
  • Downspout tie-ins so roof water joins the system

A great drainage plan uses the right mix of these tools for your specific yard. That's the difference between a fix that lasts and one that just moves the puddle a few feet. See examples in our [case studies](/case-studies) and learn the full [process](/process).

Frequently asked questions

What is a catch basin used for?

Catch basins collect surface water from low spots, driveways, and patios and route it into a drain pipe system.

Do catch basins replace French drains?

No. Catch basins handle surface water; French drains intercept subsurface/groundwater. Many yards need both.

Will re-grading fix standing water alone?

Sometimes for mild surface pooling. High water tables usually need subsurface collection and discharge.

Can you fix flooded patios and lanais?

Yes — channel drains, catch basins, and French drain/sump systems are common patio fixes.
