Water Sensitive Cities concept

Discourse vs. Reality

This post is based on my observations to two Danish Cities following the recently concluded IWA Conference last week.
 Cities visited included Middelfart and Aarhous. 

Observations and commentary

1. Scale, Climate and End Use : Determines the specifics of renowned urban water and waste water projects in Europe. 

Aarhous city is the second largest city of Denmark. Its river front development and flood proofing is considered a world class example of climate resilient city. The work done is indeed v good and appropriate for the city of Aarhus.What is important to note is the scale. The length of the river that flows into the harbour city, is only about 10Km from its origin in the hills. Relatively v small compared to the length and volume of waters in Indian rivers. Flood proofing is done by building underground cement concrete water storage reservoirs that can hold rain water and release it at a controlled rate. 

The city of Middlefart is only about 40,000.  Water sensitive design interventions include a surface drainage system that allows water to flow from the centre of the road in one locality. In another locality, there are small water conservation interventions next to the road and in parks. The small hilly landscape allows for quick discharge of water in different directions of the town, without the need for a drainage system. 

The cold temperate climate does not allow mosquitoes to breed in water storage zones.

 2. Framework fallacy : developing countries can leapfrog from poor sewered and poor drainage cities, to water sensitive cities.

"Considering more than 50% of cities are not fitted with a sewer system or storm drainage, developing cities have the potential to leapfrog towards greater water sensitivity through the provision of multi-functional and multi-purpose water infrastructure. Yet many developed cities have historically heavily invested in single purpose systems, and consequently must keep investing in the maintenance and upkeep of these systems.”

This fallacy emerges from the global north, that does not acknowledge the context, scale and climate of developing global south countries that is very different from cities of global north. It is often copy pasted on global south cities.

Our global south cities, the v large metros, need good drainage systems(alongwith water recharge). Because of the scale at which they have grown, generating substantial rain water run off. And as a result of climate change that is intensifying the water cycle leading high rainfall periods as we witnessed this year in Bengaluru, Lucknow and currently in Delhi and Gurgaon.
