🕳️ Manholes: represent points in the sanitary sewer system where loads enter into the system. Manholes are normally located at places where pipes connect and where pipe characteristics such as diameter and slope change.
🚪 Outlets: designate discharge points (e.g., treatment plant, ocean outfall) where flows exit the system and are the most downstream points of the collection system.
🛢️ Wet wells: are structures in the collection system that collect wastewater flows before they are pumped into force mains for transport to another gravity system.
🚰 Pipes/Channels: are circular/non-circular conduits through which flow is transported either by gravity (i.e., gravity mains) or by the energy supplied from pumps (i.e., force mains).
🔧 Pumps: are devices that raise the hydraulic head of water through the sanitary sewer system.
How InfoSewer models the hydraulic behavior of each of these physical components is reviewed in the following sections. For the sake of discussion, all wastewater flows are expressed in cubic feet per second (cfs) 💧, although the program can also accept flow units in various other formats such as gallons per minute (gpm), million gallons per day (mgd), and so on. Wastewater represents the spent or used water from residences, commercial buildings, industrial plants, and institutions, together with minor quantities of ground, storm, and surface waters that are not admitted intentionally 🏢🏭🏠.
