Household liquid waste

And it is called a sewage water used in the household units or public buildings.

    Industrial Effluents

They waste resulting from the use of water in the different manufacturing processes, these wastes may contain toxic materials or harmful factories are linked to a network discharge after achieving certain conditions.

    Leachates

It is the water that seep into the drainage pipes or manholes.

    Rainwater

In modern networks rainwater is separated from other waste
Terms of network design

Requires the design of the drainage network private and in-depth studies to achieve maximum utilization of the network, and these studies are:

    Data rates of consumption.
    Develop plans for the development of a receptor for the network.
    Geographical maps of the area.
    Places repositioning of industrial and commercial areas.

Drainage ways

Waste is discharged in several ways and prefer to use gradient in the discharge process, to reduce the cost. The pumps are used when difficulties.

The transfer of large amounts of waste and fonts are a big pipe or a huge tunnels in some countries with high intensity.

    Sub-drainage lines.

    High resistance to corrosion.
    The ability to withstand different temperatures.

    Types of pipes

    Metal tubes
    Reinforced concrete pipes or normal.
    Plastics pipes

Maintenance

Sewage networks require periodic maintenance operations and specialized, so as to maintain a network of wastage factors and to achieve maximum utilization of the network. And maintenance are the following ways:
