Overview

Water provided to Makers Valley comes from the large Vaal Dam which supplies the majority of water to Johannesburg. After it is piped from here, water is stored in a reservoir at the top of the hill in Yeoville. Variable speed pumps then distribute the water into the network supplying the residents and businesses of Makers Valley. The water quality is very high and considered safe to drink, although microplastics have been detected.

However, Johannesburg is the largest city in the world that is not built near a natural body of water large enough to support its growth. The majority of the water for Johannesburg is transferred from neighbouring country Lesotho, but the climate crisis is now threatening the future of Lesotho’s water supply impacting people from Lesotho as well as the people of Johannesburg.

Student teams from across the UK and Ireland created design solutions to address a challenge being faced in Makers Valley. Explore the submissions below and cast your vote for the People’s Prize

Crack Attack

Cracks in buried water pipes are common and often go undetected. Besides the impact of continuous water loss, they represent significant health and environmental risks. To detect cracks and reduce risks, pipes should be controlled periodically, a solution almost impossible to implement due to the difficulty and prohibitive cost of digging up long pipe networks. To allow for a simple and cost effective control of water pipes, we have designed the Crack Attack, an innovative autonomous device, which inserted in a pipe will monitor the inner walls along the network and detect cracks using infrared technology.

ASTON WITHOUT BORDERS

From this research a solution was deduced, this solution presented a new way to collect, filter and heat water on a personal/residential level to help combat water shortages and the issues generated with alternative ways of heating. This outcome is significant for the surrounding area as it will mean that there are less health risks to the people living in the area from fumes and open sources of heat in their homes. This will also provide a monetary aid to users as it will provide a constant source or backup supply of clean drinking water.

Waste4Water

‘Waste 4 Water’ will be a hub, a safe space for people to gather and connect as a community. The system exchanges recyclable waste for hot showers. It will be a focal point for the people of the Bertram’s area, making use of undeveloped land and symbiotically cleaning the streets, giving people what they really need in return. Staying clean is paramount to getting a job and having a sense of pride in one’s self, however many people in Maker’s Valley don’t have the privilege of hot showers. The proposal, ‘Waste for Water’, tackles this issue.

Worldwide Engineers Report

The following report details how Worldwide Engineers (WWE) interpreted the design brief for engineers without borders design challenge. WWE decided to focus on water infrastructure however we went on a few iterative topics of interest before settling, all of which are detailed below. WWE details how they went about determining that the residents of Maker’s Valley were their primary stakeholder. Alongside how they determined that a siphon tank and toilet-sink combination was the most ethical and viable solution to the water crisis.

Underground Water Tank

To provide two water tanks using the river to supply water. Built under a park which the river flows below which will be connected to pumps above ground. One pump will be located next to an allotment for growing vegetables and plants. While the other is open for use to anyone to allow people to use for cleaning.

The Infiltration Initiative

Extreme weather events are only expected to increase in extremity and frequency due to global warming and therefore Makers Valley needs to be prepared for flash floods. The three sustainable drainage solutions mimic nature in the way stormwater is transported and stored providing many economic, social and environmental benefits.

Water Saver

There is a major water crisis in South Africa. An often overlooked component effecting this is water used by toilets. Flushing toilets creates large amount of water wastage especially with multiple families in one household utilising one toilet which is common in Makers valley. We have designed a model that is cheap, fast and an easy solution to help save large amounts of water that is regularly being flushed. This will ultimately help the water situation in Makers valley and reduce the cost of water per household.

The Makers Valley: Futureproofing the Communities Water Supply

The water supply to the area is something that was highlighted as a key issue. The system is coming under increasing strain due to ageing infrastructure and a lack of maintenance. With Johannesburg having on average of 700mm of rainfall a year, concentrated mainly in the warm summer months, we thought this would be a great opportunity to devise a sustainable rainwater harvesting system that could provide a reliable supply of water during those summer months.

Sustainable Urban Drainage

Our proposal aims to tackle the issue of surface water contamination by intercepting runoff water via a system of SUDs- infrastructure designed to capture and water allowing some level of biological treatment to take place while water is drains into sub-surface layers. The proposal will reduce contamination directly by intercepting and containing contaminants and indirectly by reducing the burden on the inadequate sewage system.

The Water Crisis in Maker’s Valley

In Maker’s Valley, we found that water is very expensive. There are a lot of social problems and because of this, the more rich people use more water, making the cost of water increase. We wanted to create a solution that would help families with their financial situation by offering a single cost solution that would help them get free, clean water. Our solution is to clean and purify rain water by fixing the vertical gutter pipe of a dwelling to two water barrels. The gutters will be cleaned and the end of the gutter has a filter to stop leaves or excess dirt going into the barrels. Inside the barrels contains a home-made water filtration device created from an empty water bottle, sand, charcoal, small rocks and a bit of cloth. This will clean the water of any harmful toxins and bacteria.

Water Education Platform

Residents of Johannesburg experience various types of problems accessing water. The aim of this project is to research what the main problem is and to find a solution. It was found that people struggle with paying their water bills, in addition, experts predict that the city might run out of water, similar to Cape Town. It was clear that less use of water could help solve both problems. It was found that teaching people about saving water could help residents reduce their use of water thus reducing their water cost and trying to prevent the coming water crisis.

Water Gathering System

Project Objectives:
• Reduction of tap water consumption in households by 3.75%
• Creating a system which does not require electricity to work
• Creating workplaces in plumbing, services and manufacturing sectors by introducing our system
• Reduction of water waste due to the leaky connection system
• Utilising rainwater harvesting efficiently to make the city more ecological

Group 4 The Grater Good

This project aims to both reduce flooding, and provide an independent clean water source, for the Makers valley community. The summer afternoon storms in Johannesburg can make the Jukskei river overflow. We canalise excess water to underground tanks, filter and clean it for the community. This project will also be used to give momentum to the local economy by providing jobs to the Makers Valley’s workers.

The Water Evaporation Technology (W.E.T)

The demand for water is ever increasing within Johannesburg, and will not be supported by current methods of attainment in the future. This is why our design could help communities obtain the water they need. Our design, the W.E.T, will be able to supply communities an opportunity to collect, purify and store rainwater, which will ease the dependence on other methods of obtaining water.
