Stormwater harvesting

[1] Stormwater harvesting projects often have multiple objectives, such as reducing contaminated runoff to sensitive waters, promoting groundwater recharge, and non-potable applications such as toilet flushing and irrigation.

In arid ranch land, a catchwater or cattle tank can be constructed across shallow ephemeral washes to impound and collect what little stormwater does generate there.

Five Core Steps: End Use, Collection, Treatment, Storage, and Distribution[3] Major concerns for stormwater harvesting projects include cost effectiveness as well as quality, quantity, and reliability of the reclamation, as well as existing water management infrastructure and soil characteristics.

Some projects have estimated stormwater harvesting to be twice as expensive per unit -when including operating costs- versus other potable water alternatives.

New construction of third-pipe networks in urban settings can be prohibitively expensive; therefore the ideal project will produce recycled stormwater of potable quality in order to take advantage of existing distribution infrastructure.
