Ibrahim, Malec,
Sauhammer Agenda Problem statement Objectives Not me :) Treated wastewater Calculations Introduction Centralized vs. Decentralized Consumption ratio -> table IWRM - ECON module 02 - 06 - 2013 Dr. Dieter Prinz by villagers 2896.25 m3/year

by domestic animals 116.07 m3/year

by agricultural crops in total
87764.19 m3/year

Total water demand is 90776.51 m3/year Total Water Demand per Year Etc = Et0 * kc

Crop requirement = etc * area

Gross Water Irrigation Requirement(GWIR) =crop requirement – rainfall

Net Irrigation Requirement= GWIR + GWIR (1-efficiency )
Efficiency = 45% How much water is needed to satisfy the year-round water demand of the crop in the area ? How much water is needed to satisfy the (average) water demand of all domestic animals per year? 250 liters per capita per day (ABUFAYED and ELKEBIR, 2010)

5 permanent workers :
5*250*365/1000= 456.25 m3/year

20 temporary workers for 50 days/year
20*50*250/1000 = 250 m3/year

3 families (each family have 8 people )
3*250*365*8/1000 =2190 m3/year

The total demand is 2896.25 m3/year How much water is needed to satisfy the (average) domestic water demand of all persons per year? Total demand is 76645.89 m3/year How much water is needed to satisfy the year-round water demand of 5.5 hectares of fully grown apple trees and 1.5 hectares of young trees crop? Total demand is 11118.3 m3/year How much water is needed to satisfy the year-round water demand of 1.5 hectares of a fodder crop? Water demand Water supply and harvesting Water conservation Introduction 1) Study area a) Geography b) Meteorology c) Soil 2) Problem statement 3) Objectives Coast Mari plain 50 Al Jabal al Akhdar Mediterranean(warm summer with mild winter) Cooler & frost The soils used for agricultural production are mostly reddish soils (‘Terra rossa’) of medium quality, 0.4 to 0.8 m thick -> In Barimah it is >0.8m 400-500 mm on the mountain ~ 200 mm in Barimah http://media.newindianexpress.com - Only GW available - GW is depleting - Different usages http://cnx.org Calculations Demand Supply deficit Suggestions Conservation Alternatives Reduce
