	Pit inlet depth-discharge data can be obtained from a variety of sources. The most common typically being from suppliers or local agencies who enforce consistent design standards within their jurisdiction. For demonstration purposes, examples from Sutherland Shire Council and Brisbane City Council are provided below.		Pit inlet depth-discharge data can be obtained from a variety of sources.

			== HEC22 ==
			The HEC-22 method applies standard hydraulic relationships from the [https://www.fhwa.dot.gov/engineering/hydraulics/library_arc.cfm?pub_number=22&id=189 <u>Urban Drainage Design Manual, Hydraulic Engineering Circular No. 22 (2004)</u>] to estimate how much surface flow is captured by a pit and how much bypasses.
