DESIGN OF WASTEWATER IRRIGATION SYSTEMS

DESIGN OF WASTEWATER IRRIGATION SYSTEMS

• The enormous increase in the generation of waste water on account of rapid growth of industrialization and urbanization has posed serious threat on human and natural resources.

• Wastewater has become a significant issue in urban areas especially in developing countries.

• Land treatment of wastewater which is economical among other conventional methods which is viable solution for the treatment and disposal of water particularly for the developing countries such as India.

The following techniques of disposal of wastewater on land are discussed in detail below.

• Rapid infiltration systems

• Overland flow systems

• Vermiculture and sludge calculations

 Land disposal systems are used for:

• disposal of pre-treated municipal effluents
• not used extensively due to large land requirement and this reason is aggravated by code-required setbacks (municipality requirements)
• not used frequently due to requirement of significant pre-treatment before application

•
