Presentation Overview
HUBER SE . www.huber.de
• A brief history of time (for cities).
• Why do we need to change from ‘Business
As Usual’ for our cities of the future?
• What are some alternative concepts?
• How do we implement it?

A Brief History Of Time – Mid 1800’s
1850’s & 1860’s:
Widespread construction of city
sewers starts around the world.

Infrastructure Resilience
HUBER SE . www.huber.de

The Typical City Of Today
The limits of natural ecosystems
is being reached
Potable water brought in
Waste water removed
$$$$$$
$$$$$$ Extensive Pipes in the
Ground Infrastructure.
$$$$$$ $$$$$$
Expensive, Inflexible & Aging.

Non-Potable Reuse Possibilities
Landscaping
Amenity
Fire/Washdown
Groundwater Recharge
Irrigation

The Cities of the Future
Decentralised or Semi-Centralised
Infrastructure
Advanced wastewater
treatment with water
recycling
Better use of water
More resilient network
Adaptable to change
LESS Water brought in
LESS Wastewater removed

Sewer Mining For Water Reuse
HUBER SE . www.huber.de
1. Sewer
2. Manhole with screen & pump
‣ Wastewater is extracted from a
street main sewer and treated with
MBR to make it clean and safe.
‣ The treated water is then recycled
for irrigation of parks, golf courses,
sports fields etc.
