Theme 1 

Expand access to clean water

CONTEXT

In the quest to reduce water loss and promote water efficiency in urban areas with rapid population growth, the need to plan for water resources and budget for water utilities becomes inevitable. We must keep track of water usage possibly through carrying out water audits in our homes but more significantly in factories and industries which consume large water volumes.

A survey of residents from the Ilala District in  Dar es Salaam Region revealed that 97.5% of respondents extract water from wells close to pit latrines and, moreover, that they do not treat this water. Most of these wells are contaminated with fecal matter and as a result, people end up drinking contaminated water. How can we tackle this issue from both the supply and demand side by educating people on the dangers of contaminated wells and by providing them with access to safe water within a city that is rapidly urbanizing?

The other problem is; when people litter, this trash often blocks the intakes of sewer drains. As a result, rainwater collects in these areas and causes flooding, which can block roads or damage homes and businesses. How can we reduce the frequency of littering and therefore of localized flooding?

THE CHALLENGE

  1. How might we improve reliable access to clean water in Dar es Salaam?
  2. How can we make it easier to pay for water (for example, subscriptions model at non DAWASCO points)
  3. How can we reduce the litter which blocks sewer intakes and causes localized flooding? (e.g. the electricity utility that pays for trash in order to get more people registered officially or in beijing they give you trip credits for picking up trash in subways but only on your official card).

 

WHAT ARE WE LOOKING FOR?

Population growth in Dar es Salaam is a great contributor to water inefficiency, we are looking for creative and innovative solutions to combat water inefficiency as a vice kindled by rapid population growth.

We are looking for  hardware or software solutions to combat water contamination issues caused by mismanagement and poor planning of sewage and piped drainage systems

We are looking for technological solutions to ensure Dar es Salaam maintains a continuous water supply.

CONTEXT

The pipes that carry water from treatment plants to end users in Dar es Salaam are aging and much of the water that goes in at one end does not drain through the pipe(s). It is lost through leaks along the way. There are many ways to monitor the quantity of water flowing through the distribution network with, for example, flow meters. These are often installed in homes and businesses to monitor water consumption. However, water meters have not been installed in Dar es Salaam and as a result, it is nearly impossible to know a) how much water an end user is consuming and b) how much water is lost during transmission to that user. Often water meters are vandalized for parts. 
 

CHALLENGES

  1. How can water authorities track water distribution and consumption?
  2. How can we reduce water loss?
     

WHAT ARE WE LOOKING FOR?

The Dar es Salaam Water and Sewage Authority have reported that Dar es Salaam losses half the cities water due to leakages, this loss is estimated at 53 percent of the total city water supply. We are looking for alternative water system tracking solutions that will minimize water loss caused by dilapidated and inadequate infrastructure for water delivery.

With the constant influx of water swindlers, water accountability is a challenge that must be tackled in a quest to create water efficiency in Dar es Salaam. We are looking for solutions to promote accountability and influence integrity in water distribution and usage.

THEME 3 

Improve the operation and maintenance of existing infrastructure

CONTEXT

Issues of water cable theft should be dealt with as criminal economic sabotage since the ripple effect of the commonly known as petty human behavior which leads to clogged water systems, water contamination among other issues is a collaborative failure of water authorities, the public and the law.  

Creating awareness of bad practice for example vandalism which exposes water systems to foreign materials and objects that potentially block water systems causing water shortage for days require permanent solutions.
 

CHALLENGES

How might we reduce the risk of water sabotage which result in water loss and blockages in the drainage system?

WHAT ARE WE LOOKING FOR?

We are looking for a cost effective solution to tackle the issue of water supply system  blockage that lead to breakage of pipes, contamination of water caused by human activities.

We are looking for a socio-affective, creative and innovative solution that aim at creating awareness on proper use of water and water systems, water storage, importance of water recycling among others
