Ready, Set, EMPTY! Pit Latrine Emptying Skills Challenge in Lusaka

Ready, Set, EMPTY! Pit Latrine Emptying Skills Challenge in Lusaka

At the 8th Zambia Water Forum and Exhibition (ZAWAFE) on 11th-12th June 2019 in Lusaka, a very engaging Skills Challenge was conducted with 28 contestants from 14 different Zambian water and sanitation utilities. After two international Skills Challenges at FSM4 and FSM5 (Faecal Sludge Management) conferences, the GIZ sector programme sustainable sanitation (SV NaSa), the GIZ programme Climate friendly sanitation services in peri-urban areas of Lusaka (CFS), together with BORDA, the Sustainable Sanitation Alliance (SuSanA) and the Faecal Sludge Management Alliance (FSMA) now organised a national Skills Challenge with utilities from all over Zambia.

The challenge was to empty a mock pit latrine filled with simulated pit sludge, then transport it safely to a designated location. The teams had to demonstrate the proper use of Personal Protective Equipment (PPE) and hygiene practices while emptying the pits and delivering the contents as efficient as possible. Participants had to master obstacles that occur in the daily operations, such as (fake) poisonous snakes, and steering the wheelbarrow through bumpy and narrow paths. All this under time pressure competing with other teams and the possibility to gain or lose points in the final scoring.

The winning team was the Chazanga Emptier Team from Lusaka Water and Sanitation Company (LWSC). The Minister of Water Development, Sanitation and Environmental Protection (MWDSEP) handed out all the awards to the emptiers during the award ceremony. This was an excellent level of recognition for the emptiers and a great signal from the Minister.

The aim of the challenge is to inspire professionals to demonstrate their skills and show the limitations and requirements of their daily work life to sector stakeholders. The challenge is not only of notable educational value in raising awareness of safe, effective and efficient pit emptying practices, it also aims to elevate the profile and visibility of the pit latrine emptying profession by actively demonstrating the importance and value of the work as essential for maintaining healthy living environments. This in turn aims to instil a sense of recognition, motivation and empowerment in competitors and underline the need for more qualified professionals in the field.

Re: Ready, Set, EMPTY! Pit Latrine Emptying Skills Challenge in Lusaka

Interesting idea.
I am just wondering what the mock pit latrine contained, i.e. how did you make up the simulated pit sludge? Is there a "standard recipe" that is used worldwide for this? Does it contain any solid waste or just a slurry of manure for example. It's the variety of solid waste and the foul odour that make it such a difficult and upleasant job...

Re: Ready, Set, EMPTY! Pit Latrine Emptying Skills Challenge in Lusaka

@ Elizabeth
The mock pit latrine sludge contained all solid waste materials that could be found in pit latrines in Lusaka and these include plastics, bottles, hair weaves, metal cans, nappies, diapers, etc
The materials were blended in a slurry of compost with the use of a concrete mixer.
The solid waste is what makes the job very unpleasant. Some pits are very thick because of the solid waste and makes almost all the mechanical pit emptying equipment to fail.Limited solid waste quantification in pits revealed a wet solid waste content of 150 kg per cubic meter of emptied sludge. Therefore, only manual pit emptying technologies have a 100 percent success rates

Re: Ready, Set, EMPTY! Pit Latrine Emptying Skills Challenge in Lusaka

Hi Aubrey,

Welcome to the SuSanA Discussion Forum! About the solid waste, has your organization ever tried to get people to dispose their solid waste separately from the excreta, i.e. not in the pit latrine but elsewhere? Is this something that could work or not possible? Would we have to dig a second pit that is only for solid waste, versus the pit (sealed with a SaTo pan maybe) that is used for the pit latrine? (See also this related thread: forum.susana.org/sato-pan-latrine-with-c...w-into-a-pit-latrine )

Also you said it's the solid waste that makes the job unpleasant. I am assuming in addition to that it's also the smell that makes it unpleasant plus the danger of disease transmission (two factors which you couldn't (and wouldn't want to) replicate with the mock pit latrine sludge).

Regards,
Elisabeth

Re: Ready, Set, EMPTY! Pit Latrine Emptying Skills Challenge in Lusaka

hello all,

I have been in Lusaka when we (LCC, LWSC, GIZ, ...) had field trials emptying pit latrines in Lusaka's high density, low income compounds (peri-urban as they call it) in 2017, testing the gulper, eVac and FlexCravator and noticed the problems all pumps had with the solid waste and especially with the plastic bags mixed in the sludge. This is why Aubrey says, only manual emptying (using long handle rakes and buckets) can deal with that.

Lusaka City Council (LCC) has a system of solid waste collection which should help that people do not use their latrine pits as solid waste dumps: community based enterprises (CBE) are subcontracted by LCC to collect waste from the households and accumulate it in a central place of the compound from where LCC should transport it to the municipal waste dump.

The system works only to a small extend. The problems are: LCC does not have enough capacity collecting the waste from all compounds regularly, the waste accumulates in the central place in the compound, the CBEs get frustrated and reduce collecting, the customers stop paying because waste is not collected regularly, the CBEs stop collection completely.

Having noticed this vicious circle having its cause in the LCC's low collection capacity, we initiated in LCC the discussion that the Lusaka Sanitation Program funded with about 300 mio USD from donors should divert some funds to LCC improving their collection capacities. A project proposal was developed and costed (3 mio USD, i.e. 1% of the program budget). In first discussions between LCC, Lusaka Water & Sanitation (LWSC) and the Banks, the initiative was judged positively. I then left LCC and Zambia, but maybe Aubrey can find out what happened to this proposal.

Enabling LCC to collect the solid waste from the compounds regularly would definitely reduce the amount of solid waste getting into latrine pits. And once a working solid waste management exists, LCC has the right enforcing the use of this system and punish the misuse of latrine pits as solid waste dumps.

ciao
