Exploring the Functions of Water Inlets and Outlets
Water storage tanks are essential for collecting and storing water from various sources such as rainwater harvesting systems, canals, and boreholes. In order for these tanks to function properly, they require inlets and outlets to regulate the flow of water. In this article, we will delve into the ins and outs of water inlets and outlets, and discuss different types of outlets and their functions.
The inlet is where water is introduced into the tank, while the outlet is where the water exits to other tanks or the point of use. Inlets are typically positioned near the top of the tank, while outlets are located at or near the bottom to ensure the tank can be fully emptied when needed. The placement of these elements depends on factors such as the tank’s size, shape, and intended use.
There are several types of outlets available for water tanks, each with its own unique features and advantages. Conical outlets, for example, are manufactured using customized machinery and come with a footplate and conical sleeve made of the same material as the tank lining. This makes for a watertight fit over the connected pipe. These outlets can also be installed “blind,” without creating a hole in the liner, allowing for easy removal if needed.
Mechanical outlets, on the other hand, are ideal for situations where the exact location of inlets and outlets is not determined. They consist of PVC flanged outlets that can be installed on-site using a screw connection. These outlets are typically placed at the bottom of the tank and come in various diameters, allowing for almost complete emptying of the tank.
Galvanized outlets are specifically designed for installation in tank walls and are used for filling, drawing, and partially draining the tank. They are typically placed halfway up the tank panel, leaving approximately 40 cm of water in the tank. These outlets are made of galvanized steel and are durable and long-lasting.
In conclusion, water inlets and outlets play a crucial role in the proper functioning of water storage tanks. Their placement and type depend on various factors, and it is important to carefully consider these elements when installing a tank.
