CPC SOUTH AFRICA
2016 – Extension 1 Diepsloot, South Africa
The aim of this event is to repair and upgrade 8 x communal toilet cubicles that were removed from within Diepsloot. Since 2013, HH has been working with the local water and sanitation maintenance group WASSUP (Water, Amenities, Sanitation Services Upgrade Programme) and Sticky Solutions to deliver upgrades to existing communal toilet blocks installed in Diepsloot. Local government installed the communal toilets and water and sanitation infrastructure after the settlement emerged and most are in disrepair, leaking water and waste water, compromising health. Most were not delivered to a standard that could withstand the population of use, as most residents do not have private bathrooms or water supply points. WASSUP formed as a local resident group with the aim to maintain and improve these amenities, and worked with HH in setting up a sanitation program.
The first stage of the project was achieved with the following methodology:
- Preliminary site visit and review of challenges,
- A multi-disciplinary workshop was run in Sydney reviewing different elements of the toilets design and specification and how they could be best upgraded. The workshop was attended by a range of skilled people including architects, plumbers, builders, policy writers and environmental health workers,
- The designs were presented to ZA local group Sticky Situations and WASSUP for their feedback
- A final design and specification report was collated and sent to WASSUP for their review
Once all agreed on the best way forward, planning started to commence the first upgrades involving:
- 10 upgrade toilets identified by local group for upgrade work along with an additional 10 ‘control’ toilets nearby were metered for base data on water use;
- WorldSkills Foundation organised two skilled International plumbers to join the local team in upgrading and improving the toilets;
- HH worked with WASSUP to carry out design, installation and data collection.
- The result of a week of hard work installing new health hardware was not only improved sanitation and amenities but a total water saving of over 750,000L by eliminating leaks.
- WASSUP then exhibited the data to their community and Joburg water to illustrate the impact small, inexpensive upgrades and ongoing maintenance was able to achieve, resulting in ongoing support for WASSUP’s good work and the upgrade of a further 40 toilets (stage 2).
The Challenge outcomes:
This year, the CPC sets the challenge to find new and improved design, plumbing and specification ideas for these 8 toilet cubicles which will then be retrofitted and reinstalled in Diepsloot for further testing. Always with the aim of improving our approach for health gain, HH, WASSUP and Sticky Solutions are looking for innovative ways to improve these health giving facilities with the help of the teams of skilled plumbers, designers, engineers and communication experts from USA, Australia, India and South Africa.
In the spirit of Nashik, the event is coordinated to give each team a chance to present their proposals to the local and international event organisers, and then merge the best ideas into one or more solutions that will be installed to the cubicles off site. Once retrofitted, the cubicles are then installed in Diepsloot on the final days of the event.
HH has supplied data logging equipment to be installed in the upgraded toilets during the event, to log water use to the toilet and water point against the population of use. The aim is for the toilets to be providing active and specific data over a three-month period to help identify any successes and failures of the units as they are real-life tested. This will help teams monitor the progress of their work after the event and WASSUP gain more information for ongoing maintenance of the toilets to build on their tools for improved daily monitoring and up-keep.
The design and delivery results of the challenge will be published here along with the final report.
