Drips and leaks: water loss and annual costs
Estimate average leak water and costs from measured volume or your drop size.
Estimate average leak water and costs from measured volume or your drop size.
Drop size varies by faucet; prefer measured volume. There is no exact fixed standard drop size. Assumes constant leakage, which may worsen or vary. Even small leaks can damage buildings; check unusual leaks promptly. No DIY repair or plumbing advice.

Method
Flow (L/min) = L ÷ s × 60; Drips: Drips per minute × mL ÷ 1000
Daily average water (L) = (L/min) × Leak hours per day × 60 × Active days per week ÷ 7
Water already lost (L) = Daily average water (L) × Days already leaking (optional)
1 US gal = 3.785411784 L; 1 mL = 0.001 L
Annual water (L) = Daily average water (L) × 365; Monthly average water (L) = Annual water (L) ÷ 12
Annual cost = Annual water (L) ÷ 1000 × (Water rate + Sewer rate (optional)); Monthly average cost = Annual cost ÷ 12
