Water Challenge
Eco Pure - Water Open Call
The inefficiency in centralized water system and high cist of building such system in rural communities deter such communities from access of clean and affordable water supply. The aim of Eco Pure water design challenge is to address this situation and design a water system that is affordable, self-sustaining, compact and motivates community living. This open call to welcomes innovative solution submission from students, graduates and professionals.
Challenge
The water design should consider the local context and growth from unit to community scale specific to South East Asian Climate. The system should be able to operate independently without the connection to the main water supply system. Create your own scalable, self-sustaining, modular ECO-Pure which focuses on human centric design supported by technology. The specification of the solution are listed below.

Requirements
- The Water Designs should be for Portable and Non-Portable uses
- Overall, the integrated system needs to meet at least 70 litres of water consumption per day per person, with the design meeting the water consumption needs of at least 3-5 people
- Portable Water (Eg. Atmospheric water generator)
- Need to supply at least 100 litres of drinkable water per day
- The solution should operate optimally indoors (air-conditioned) and outdoors
- Minimum requirement of 45% relative humidity for water generation system needs to be met
- Water quality produced needs to meet the PUB Portable Water Quality Standard
- Cost effective and compact in size
- Low maintenance and associated costs required

Requirements
- The Water Designs should be for Portable and Non-Portable uses
- Overall, the integrated system needs to meet at least 70 litres of water consumption per day per person, with the design meeting the water consumption needs of at least 3-5 people
- Greywater Recycling System
- Could handle at least 25 liters of greywater per day per person
- Achieve at least 70%-80% greywater recycling (Reducing potable water uses)
- Treated greywater needs to meet with the Singapore PUB and WHO standards for greywater quality
- The system should include the basics treatment systems
- Sedimentation / Screening – Biological and chemical treatment
- Membrane bioreactor and filtration – Disinfaction using UV/chlorine
- Cost effective, short assembly and disassembly time
- Low maintenance requirement and fee
- Discharge of effluent to meet with PUB Trade Effluent Standards
-
Two suggested systems which include greywater/black water recycling and water sourcing system for non-potable uses
(Examples include rainwater harvesting system) - Both systems need to be integrated to increase the circularity of grey water for non-potable uses
