Flats vs. hillsides
Near the Cowlitz, crawl spaces often sit low with no downhill outlet, so a sump pump is the practical choice. On Kelso's eastern slopes, water collected along the uphill wall may be able to drain by gravity to a downhill outlet — no pump needed. We look at the lot before recommending one.
Hillside lots and gravity
On Kelso's slopes, water collected along the uphill wall can sometimes be piped by gravity to a downhill outlet — no pump, no power, fewer moving parts. Whether that works depends on the slope of the lot, where the outlet can be, and how the crawl space floor is shaped. On the flats near the river, gravity rarely works and a sump is the practical choice.
The installation
- Basin at the low point
- Pump and discharge line routed away from the house
- Lid and barrier sealed around the basin
- Often combined with drain pipes
Discharge on hillsides
On a slope, where discharged water goes matters. Water released above a slope can soak back into the hill. We plan the route to send it somewhere appropriate.

Discharge matters on slopes
Releasing pumped water above a slope can send it right back into the hill. We plan discharge to go somewhere appropriate.
Questions from Kelso homeowners
Do I need a sump pump on a hillside lot?
Hillside lots often drain by gravity, and some still need a sump. We'll check yours and recommend the right setup.
Where should the water discharge?
Away from the foundation and not onto the slope above. We plan it with you.
