Introduction
IntroductionAfter a treatment concept has been selected and a preliminary site layout has been determined, the next step is to determine the hydraulic profile (water surface profile) or hydraulic grade line (HGL) for the water resource recovery facility (WRRF) and the unit processes therein. The objective is to ensure there is adequate head available to allow the wastewater to flow from one unit process to another and establish the appropriate control weir elevations and water surface elevations within each unit process to ensure that adequate freeboard is provided. This may include making conduits and channels large enough to meet future expansion beyond the capacity required during the design year. Sufficient hydraulic head should be provided to permit good distribution of the facility flow to all treat…
