Why ?

Water Resource Act (2013) Malawi
Water Resource Act (2013) Malawi 35 (1) Water Resources Authority The National Water Resources Master Plan shall, among other things, address matters relating to the conservation of water resources, including through the recycling and re-use of waste water, …… 74. Every person abstracting groundwater by means of a borehole shall, in order to prevent contamination or pollution of the and pollution, dispose of all return or waste water by means other than by return to the borehole 87 (1) Activities which constitutes controlled activities controlled include activities (a) Irrigation of any land with waste water generated through any industrial activity or a water work; (c) artificial recharge of an aquifer with any waste or water containing waste; 89 (1) Any person who owns, controls, occupies or uses land water resources which an activity or process is or was performed and which, unless authorized under this Part, causes, has caused or is likely to process cause pollution of a water resource, shall take all such measures as may be necessary to prevent any such pollution from occurring…..

Water Resource Act (2013) Malawi
Water Resource Act (2013) Malawi 140 (1) An inspector may enter land for purposes of inspecting the land in relation to use of water…. (a) inspecting works or use of water; or (b) taking samples or making tests, to find out whether (i) water is being wasted, misused or polluted; (ii) the terms of any water permit, waste discharge permit or (iii) any other permit granted 145 (I) No person shall wilfully obstruct, molest or hinder any inspector or other employee of or person authorized by the Minister or the Authority acting in the exercise or performance of his powers and functions under this Act; (d) without lawful authority, wilfully let off or discharge water from the works of any permit holder so that the permit holder loses the use of that water; (e) without lawful authority, lay, erect or construct, or cause to be laid, erected or construct, any work to connect with the work of any permit holder which is capable of drawing water from that work;

Water Resource Act (2013) Malawi
Water Resource Act (2013) Malawi Offences 73 (1) No person shall not …. cause any groundwater to flow to waste from any borehole, or groundwater except for the purpose of testing the extent or quality of the supply or cleaning, sterilizing, examining or repairing the borehole; (b) conduct the water from any borehole through any channel or conduit so that more than twenty per cent (20%) of the water is lost between the point of extraction and the point of use:….. (c) use any water from any borehole for the purpose of domestic use or the watering of stock, except where such water is channelled through pipes fitted with float valves or other satisfactory means of control, to prevent waste: 74 Water Resources No. l (2) A person who contravenes the provisions of subsection (1) commits an offence who (a) Allows water to be wasted……. (b) takes or uses water for a purpose other than provided by the water permit,

Why Permaculture?
7
Why did CJF Project bring to WFP
the concept of Permaculture to include in all of the villages in Chikwawa ?? Water Resources Act (2013) Malawi This is illegal Health point of view This is a source of disease From an Economic Point of view This is WASTED MONEY
8
Development Depends on Groundwater GROUNDWATER IS 97
Development Depends on Groundwater GROUNDWATER IS 97.6% of ALL AVAILABLE FRESH WATER A Real Economic Value Why Throw Away Money?
9
Integrated Water Resources Management Contamination of Water
NEED Integrated Water Resources Management @ Local Scale Wasted Water Contamination of Water Source of Disease
10
Water Right Payment Who Pays?
11
Water as Economic Value
Our Role Water Resources Act (2013) Malawi IWRM Enshrined in Act Government ‘Owns the Water’ Government has responsibility to provide means of access to water as a human right Government Sets Access Measures (Abstraction and Drilling License Fees e.g. Water Right Payment for Borehole) DO YOU PAY? WRA then Allows Local User to Collect on Behalf of Government the Economic Value of the Water: they are not taxed for water. Local IWRM is part of Water Resources Act, not something new
12
WRA 2013 & CJF Community IWRM Permaculture, Borehole Banks, BUAs
Traditional CBM Has Failed We Recommended to WFP to Replace with Local IWRM Payment of Water Right allows Value of water to be properly recovered. Income then used for community loans to enhance income and underpin Healthy Communities Wasted water now used for crops Cash Value of wasted water $100 to $300 per year Recover wasted water Turn it into Cash Use Cash for Preventative Maintenance of Water Resources within the Local Community

When Groundwater Declines Rivers Dry Up During Dry Season
You are Here When Groundwater Declines No Base Flow to Rivers Rivers Dry Up During Dry Season

21
It Rains for 3 Months Water Soaks into the Ground It’s Dry for 9 Months How do the Rivers Still Flow? Groundwater Provides Water to Rivers as BaseFlow Without Groundwater Storage, Lake Levels Decline Faster ! Solution: Manage the land to make sure groundwater recharge return to normal levels.

CJF ‘Hands On’ Training for
Groundwater Resources Management CJF ‘Hands On’ Training for Rural Community to Manage and Measure Water Resource, Water Measurements Local Materials Proactive Management
24
Real Reason for CJF Mapping
25
Management of the National Water Resources Asset
CJF National Asset Mapping You can only manage what you know You can only recover economic value of water is holistically managed through IWRM
26
Waste Water Human Waste
27
CJF Asset Mapping
28
CJF Asset Mapping Includes Risks
Pit Latrines Near Boreholes 2017 Data
29
Contamination of Groundwater is a Risk to SDGs
Contamination of Groundwater not Allowed in WRA 2013 How to Manage Risk from so many point sources?
30
Mapping Every Pit Latrine Too
RISK SAFE 39 Pit Latrines within High Risk Zone

Water Energy Nexus: Water Weighs A lot!

Water Energy Nexus: Water Weighs A lot!
1 Litre of Water lifted 100 meters = 1 Watt 1000 Litre of Water = 1 cubic meter (m3)
34
Water Energy Nexus: Water Weighs A lot!
1 Litre of Water lifted 100 meters = 1 Watt 1000 Litre of Water = 1 cubic meter (m3) 1 m3 of Water lifted 100 meters = 1 kilowatt Energy Efficiency of Pumping water ~ 50%

Water Energy Nexus: Water Weighs A lot!
1 Litre of Water lifted 100 meters = 1 Watt 1000 Litre of Water = 1 cubic meter (m3) 1 m3 of Water lifted 100 meters = 1 kilowatt Energy Efficiency of Pumping water ~ 50% Lifting 1 m3 of water from Lake Malawi to Lilongwe = 20 kilowatts Moving Water 100 kms from Lake Malawi to Lilongwe = Energy Loss in Pipes Energy for Pipeline Transmission Depend
