[[File:House_Figure_1.png|thumb|Residential LID options]]
On residential lands, hard surfaces such as roofs, patios, walkways and driveways can all be targeted to collect, treat, and infiltrate runoff. The practices you choose will vary depending on neighbourhood and [[Site conditions: Residential|site constraints]] and [[Planting design|landscape ideals]].

Soakaways, also known as [[infiltration chambers]] or dry wells, are excavations in native soil that are filled with clean granular aggregates. Soakaways are typically designed with a [[pipes|perforated pipe]] inlet from a relatively clean water source, such as a roof tops or pedestrian area.

When possible, install soakaways in areas where native soils allow for infiltration. If poorly draining soils are present, an [[underdrain]] can be installed to remove standing water.

==Rainwater Harvesting==
Rainwater harvesting is the process of collecting and storing rainwater for future use. Harvested water can be used for a variety of non-potable indoor and outdoor uses with minimal treatment. Rainwater harvesting provides an easy, low-cost option for homeowners to reduce the volume of runoff conveyed from their properties to the municipal storm sewer system.
===Rainwater harvesting systems===
[[Rainwater harvesting]] systems collect rainwater from roof runoff and store it until it is needed. These systems are often used for irrigation, but with additional equipment and proper treatment, this water can be used for flushing toilets. By using rainwater around the home, residents can reduce their water bills while also reducing the amount of stormwater runoff entering the storm sewer system.
Rainwater storage tanks come in a variety of dimensions and shapes to accommodate both the size and desired aesthetics of residential properties. Fro four season use, they are usually placed in the basement or buried underground.

===Rain Barrels===
While they provide similar functions to rainwater harvesting systems, [[rain barrels]] have limited storage space and seasonal function. They are installed at the outlet of downspouts and intercept water draining down roofs for later use in irrigation. Rain barrels come in a variety of shapes, sizes and styles. Residents can choose a style of rain barrel best suited to their home and personal tastes.
