New Techniques There are two main techniques of Water Harvesting 1. Water harvesting techniques may be classified into two major types, based on the size of the catchment (Figure 6): micro-catchment systems and macro-catchment systems (Oweis et al., 2001). Since rainwater harvesting leads to water provide which leads to food security, this will greatly contribute to income generation. 1.

Rainwater harvesting is important for several reasons but one of the biggest is the fact that we are tapping out water conservation gains inside our homes so we need to … Micro-Catchment Systems. Water conservation of both surface and groundwater is a key component to increase access to, quantity, and quality of water supplies to meet basic human needs, support economic growth, enhance food security, and maintain ecosystems. Rainwater harvesting is an easy and positive course of action for people in nearly every climate in the ... Rainwater Harvesting Technique 1. Several water treatment methods exist to tap these sources, from artisanal, traditional methods of atmospheric water generation to unconventional, modern techniques of desalination. 6 Methods for Harvesting Rainwater. Groundwater aquifers can be recharged by various kinds of structures to ensure the... 3. Water Harvesting Techniques Water harvesting techniques may be classified into two major types, based on the size of the catchment (Figure 14.6): microcatchment systems and macrocatchment systems (Oweis et al. where the effects of water harvesting and water-saving techniques were investigated on the soil-water balance in semiarid regions. In this method, rainwater collected from the roof of the building is diverted to a storage... 2. 2001). 2. Rainwater Harvesting Technique 3. Water harvesting and treatment technologies that are solar or wind powered is the most environmentally friendly way to extract pure quality water from the air or sea at a low cost. Six Methods for Harvesting Rainwater.

Storage of Direct Use. In a first case study, the effect of a jessr water harvesting system in Amrich, Oued Oum Zessar watershed (South Tunisia) is described and evaluated for its impact on soil and water conservation. Recharge of ground water Recharge of ground water is a new concept of water harvesting 11. Water harvesting techniques, which harvest runoff … Water harvesting in its broadest sense can be defined as the "collection of runoff for its productive use". Rainwater Harvesting Technique 2. Several water treatment methods exist to tap these sources, from artisanal, traditional methods of atmospheric water generation to unconventional, modern techniques of desalination. Floodwater harvesting is also called Large catchment water harvesting or "Spate irrigation", and comprises two forms: In case of " floodwater harvesting within the stream bed" the water flow is dammed and, as a result, inundates the valley bottom of the flood plain. Storage of rain water on surface for future use The storage of rainwater on surface is a traditional technique and structure used in underground tanks, ponds, check dams, weirs etc. Runoff may be harvested from roofs and ground surfaces as well as from intermittent or ephemeral watercourses. Rainwater harvesting will improve water supply, food production, & ultimately food security. Water insecure individuals in rural areas will advantage the most of rainwater harvesting systems. Recharging Groundwater Aquifers. Methods of Rooftop Rainwater Harvesting 1.
