57 Eiruvin 10/5-8

(5) A man may not stand in a private domain and urinate into the public domain, [nor may he stand] in the public domain and urinate into a private domain. And also, he may not [stand in one domain and] spit [into another]. Rabbi Yehuda says, "Even from when the spit has been separated in his mouth, he may not walk four amot before he spits."

(6) A man may not stand in a private domain and drink in the public domain, [nor stand] in the public domain and drink in a private domain, unless he places his head and the greater part of his body into the place where he drinks. And so also is [the law with respect] to a wine press. A man may collect [water dropping] from a drain spout below ten tefachim from the ground; but from a projecting spout [pipe], he may drink in any place [or way].

(7) If there is a cistern that is in the public domain and its ring [of earth surrounding it] is ten tefachim high, if there is a window [opening] that is above it, we may draw water from [the cistern] on Shabbat. A dunghill in the public domain, which is ten tefachim high, if there is a window [opening] that is above it, we may pour water [onto the dunghill] on Shabbat.

(8) If [branches of] a tree [droop], and cover the ground [around it], if the branches are not three tefachim from the ground, we may carry beneath it. If its roots [project and] are taller than three tefachim high from the ground, one may not sit on them. The door of a storage space, or thorn bunches [that are used to put] into gaps [in the wall to fill them up], or reed mats, may not be shut, unless they are [situated somewhat] above the ground.
