Overview

1. Why Do We Need To Change From Business As

Usual?

• Nature Can’t Satisfy Our Growing Demands

• Infrastructure Can’t Cope

• System Resilience in Seismic Regions

2. What Are The Solutions?

3. Examples In Practice

Water Stress Map


Problem 1:

More people concentrated in a small area.

There comes a point when nature cannot

meet the demands for water.



Infrastructure Can’t Cope


Water Losses from Urban Water Networks



Problem 2:

Central City infrastructure must work

harder as population densities increase.

Unfortunately this infrastructure is also

often the oldest.

Upgrading is expensive and disruptive in

the busiest part of town.

Upgrading water services costs twice: in

+ out.



• Expensive

• Disruptive

• Loss of business

• Noise/Dust Pollution

• Water infrastructure costs twice

(potable supply in + wastewater

out)

System Resilience in Seismic Regions

Source: CIESIN, Earth Institute at Columbia University


•Structures: Designed to

withstand seismic events

•Electricity: Standby generator

or multiple points of supply.

•Water: Storage tanks (8 – 24

hours supply)

•Wastewater: Typically nothing

Problem 3:

There are many cities located in seismically active

regions.

When earthquakes occur, waste water infrastructure

proves to be less resilient than other services, and

hence takes longer to recover.



The Problems Facing our Cities of Today


•More people = More resources needed. Increasingly

natural systems cannot meet this demand.

•Infrastructure in city centers is having to work harder.

Unfortunately in many cases it also tends to be old &

fragile and difficult/disruptive/expensive to upgrade.

•Conventional gravity waste water infrastructure is

relatively fragile in seismic events. Waste water is often

the weak link in re-establishing normal operations after an

earthquake.


The Cities of the Future

Rainwater

LESS Water brought in

LESS Wastewater removed


LESS Energy brought in

Reclaimed wastewater and rainwater for

amenity flow and groundwater recharge

Onsite wastewater treatment:

• reduces overall demand

• increases system resilience

Onsite or nearby energy recovery:

• reduces load on local energy supplies
