Using Sump Pump Groundwater for Irrigation: Storage and Drip Only

Chicago High Water Table: 6-7 GPM Wet, 1-2 GPM Dry from Sump

Sump runs constantly. Want to store/use for landscaping. Micro-irrigation for uphill/downhill plantings. Basement storage possible.

Volume Is Usable

6-7 GPM = ~360-420 GPH. Enough for drip/micro-sprays, not sprinklers.

System Design

• Cistern/tank in basement (poly or concrete).
• Pump from tank to drip zones (pressure needed).
• Float switch on tank to control sump discharge.

Complex—Needs Design

More thinking needed on tank size, pump, controls. Practical for beds, not lawn.
