Overview

Households and businesses in Makers Valley are generally connected to a combined sewer, as is the street water run-off. However, sanitation issues arise during the conveyance of this wastewater to treatment facilities. Ageing infrastructure and lack of maintenance have caused pipes to break, allowing contamination of the Jukskei river and its surrounding areas. During intense storms, these issues are exacerbated as the sewage system receives an influx of storm water, flushing sewage into the river. All of these factors contribute to the contamination and odour of the Jukskei, making it an unpleasant corridor through Makers Valley with the potential to cause harm to human health.

Due to its close proximity to the Johannesburg Central Business District, the Makers Valley neighbourhood is experiencing an influx of people moving into the area. This rapid growth is adding to the stress on the sewer system.

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.

HygieClean

We believe that the HygieClean is a hygienic alternative that will help clean the streets, river and sewage systems of Johannesburg. The product achieves this by encouraging the community to throw their nappies, feminine hygiene products and toilet paper in the sanitary bin as opposed to flushing these products down the lavatory or by participating in illegal dumping. The two different sections will ensure each product would get disregarded in suitable dumping sites around Johannesburg.

The Jukskei Initiative

The Hot Spot and further Jukskei Initiative focuses on improving the Jukskei river, along with improving the area for Makers Valley and Johannesburg citizens. The system and initiative are an effective and sustainable solution for Makers Valley. The project aims to resolve the highlighted issues at the root of the problem, rather than imposing a solution that would only act as a temporary repair. The project aims to have long term effects, such as developing skills of the community, future usage of the space and power, along with how the project could be taken further into other communities.

Sustainable Public Toilet

The proposed solution is a sustainable Public Toilet concept was selected for further development. This concept incorporates the use of a Solar PV system, with battery, to power pumps that tap into a ground-water source. This allows the design to operate independently of the inconsistent grid and central water systems. Use of a modern septic tank solution also allows the concept to avoid connecting to the ageing and leaking sewer infrastructure.

Green roofs as a mitigation strategy against urbanisation in Makers Valley

The design is relatively simple; layers of roof protection and soil are placed on flat roofs across Makers Valley. These roofs will house two types of plants; one portion of the roof will hold plants which are native to the local area and are endangered due to urbanization, as well as a plant known as sedum. The other portion is proposed to cultivate vegetables with shallow roots. These plants will absorb rainfall and utilize it for growth. This will lessen the amount of runoff on the streets, therefore preventing excess flooding of the streets or the river.

Disposal & Treatment of Human Waste in Makers Valley

The purpose of this report is to address and find a solution for the inadequate removal and treatment of human waste in Makers Valley. We found that a water-free toilet system that is disconnected from the main sewage system, separates the liquid and solid waste and treats the solid waste at the source, through an aerated static pile compost barrel, was the most viable solution for Makers Valley.
