Common exterior drainage problems
Wet lawns and recurring puddles may result from slope, roof discharge, compacted soil or a blocked drainage path.
Surface drains collect visible water. French drains intercept water in saturated soil. Grading and downspout routing solve different parts of the problem.
What to check before planning drainage work
- Watch where water enters during a hard rain
- Check downspout discharge points and low lawn areas
- Identify a suitable outlet before planning a trench
Start with the source, not the drain
The City of Greenville Stormwater Utility publishes the city’s stormwater responsibilities, ordinance and drainage-system guidance. If the problem involves a public inlet, street drainage or a regulated drainage feature, check that guidance before changing the outlet.
For a private yard, trace roof, driveway and uphill runoff separately before choosing a drainage method. A public stormwater system nearby does not automatically make it an approved discharge point.
Confirm where the water can go
Any proposed drain needs a lawful and suitable outlet. Do not assume water may be directed onto neighboring land or into public infrastructure.
Confirm utility locations, drainage easements, permits and other local requirements before excavation.
