* Average Earthling Lerner 2002 Identifying and quantifying urban recharge: a review Global: Cities () 0.2 proportion (0-1) "...leakage [rates] of 20–25% are common, and rates up to 50% have been observed (Lerner 1986a), causing large amounts of recharge."

Average Earthling Lerner 2002 Identifying and quantifying urban recharge: a review Tomsk, Russia: Urban ecosystem () 0.15 proportion (0-1) In Tomsk, Russia, 4–11 leaks develop every year per kilometer of water main, leading to leakage rates of 15–30% (Pokrovsky et al. 1999)
