Basins, pumps, and discharge routing
A sump system has three parts that have to be designed together. The basin collects water from area drains, french drains, or surface flow, sized so the pump is not cycling constantly. The pump is matched to the volume and the lift the lot actually requires. And the discharge line carries the water to a point where it leaves the property for good, not back into the same saturated soil beside the foundation.
The discharge is where undersized installs fail. Water pumped ten feet away in clay soil comes right back. Routing, check valves, and freeze-conscious discharge placement are part of the design, not afterthoughts.
When a sump system fits DFW clay drainage
Expansive clay makes standing water beside a slab a structural issue, not just a nuisance. Saturated soil swells, dry soil shrinks, and the foundation rides the difference. When an inspection shows water that cannot leave the lot by grade, a sump system is the honest recommendation. When gravity can do the job, it is the cheaper and better answer, and that is what we recommend instead.

Frequently asked questions
Yes, modest but real: the basin should be kept clear of debris and the pump tested ahead of the wet season. A stuck float on a neglected pump is the most common failure we see.
A standard sump pump stops. Battery backup options exist for lots where an outage during a storm would flood something that matters. Whether that is worth it depends on what the system protects, and we will give you a straight answer.
Yes. On flat lots a sump basin is often the collection point that makes a french drain system work at all, since the collected water needs somewhere to go.
