1. Integrated Urban Water Management
Tools and Training
Kalanithy Vairavamoorthy & Francois Brikke

2. Managing urban water will become
more challenging in the future

3. Are our 19 c. approaches suited to
deal with these challenges?
• Linear systems – use once
and discharge
• Drinking water used for all
purposes
• Systems fixed, centralized
designs (energy intensive)
• Stormwater viewed as a
waste (not a resource).
• Institutions not conducive
for integrated thinking
• Regulations stall
innovation, are inflexible

4. Should we change our perspective?

5. We need to have a systems
perspective of the water cycle

8. These perspectives lead to a more
decentralized type of thinking?
Decentralization well suited for:
• Energy recovery (heat recovered
and used close to source)
• Minimizing energy consumption
(for moving water)
• Source separation (to maximize
nutrient recovery)
• Adjusted growth (to deal with
rapid growing cities)
• Increased resiliency (dampens the
propagation of failures)

22. There are many technologies suited for
developing countries – but what are they?
What technologies
exist to allow me to
reuse & recycle?
How can I capture
nutrients from my
water?
What technologies
will help me
generate energy
from my water?
What technologies
exist to help me
harvest stormwater?
What technologies
will help me convert
faecal sludge into
money?
?????

23. Greywater Treatment:Household
DEWATS
Horizontal Flow Wetlands Algal Culture Ponds:
Harvest Micro-algae
Fecal sludge into safe fertilizer:
LaDePa machine (Durban)
We need a catalogue to help us understand what
technologies exist (and where/when to apply)

24. Technology Search Engine
The biosand filter (BSF) is an innovation on traditional
slow sand water filters for household level water
treatment device. A BSF consists of a concrete or plastic
container filled with specially selected and prepared
sand and gravel. Physical straining of water filter
removes pathogens, turbidity, iron, and manganese from
drinking water.

25. And a decision making tool to help us choose
the right technology for the right condition
The final product will be developed by 13th Jan 2015
