Integrated Urban Water Management

Tools and Training

Kalanithy Vairavamoorthy & Francois Brikke

Managing urban water will become more challenging in the future

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

Should we change our perspective?

We need to have a systems perspective of the water cycle

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)

Water Balance Model

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?

?????

Greywater Treatment:Household

DEWATS

Horizontal Flow WetlandsAlgal 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)

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.

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
