What equipment do I need to install a French drain?

You need a trencher or mini excavator to dig the trench, a plate compactor for the gravel base, and basic hand tools. For Southern Utah's hard soil, a walk-behind trencher or mini excavator is strongly recommended over hand digging.

How deep should a French drain be?

A French drain should be 18-24 inches deep and 9-12 inches wide for most residential applications. The trench must slope at least 1% grade (1 inch per 8 feet) toward the drainage outlet. Deeper drains may be needed near foundations.

Can I install a French drain myself?

Yes, a French drain is a manageable DIY project. The most labor-intensive part is digging the trench, which is made easy with a rental trencher or mini excavator. Most homeowners can complete a 50-100 foot French drain in a single day with rental equipment.

How much does it cost to install a French drain yourself?

DIY French drain installation typically costs $5-$10 per linear foot for materials (pipe, gravel, landscape fabric) plus equipment rental. Total cost for a 50-foot drain is typically $400-$700 DIY vs $2,000-$5,000 for professional installation.
