Abstract: A portable water collection and filtering device is described. Such water may be collected from irrigation runoff (e.g., excess water from a sprinkler system for watering a lawn or other landscaping that may run along a street gutter), rainwater (e.g., water travelling along a roof gutter, through a downspout, etc.). The portable water collection and filtering device may be able to couple to a collection resource such as an empty bottle. In this way, small amounts of runoff may be captured, stored, and utilized (e.g., to water plants). Such captured water may be provided to various other devices and/or systems (e.g., a treatment system, a larger storage unit, etc.).
