Four innovative sanitation projects in Zambia - Faecal sludge management aspects and general lessons

2013

Water Information Network (WIN-SA), South Africa

Since then, the DTF has been a major partner to CUs in financing and implementation of projects that have led to improved Water Supply Services for more than 850,000 people living in Zambian low income areas. In 2008 the DTF, in partnership with the local NGO WASAZA (Water and Sanitation Association of Zambia) and the German NGO BORDA (Bremer Overseas Research and Development Association) developed a “sanitation concept and sanitation implementation approach. In 2009, DTF started the implementation of four sanitation projects with four CUs established by Local Authorities under the Water Supply and Sanitation Act no. 28 of 1997 and duly licensed by the regulator NWASCO. The four utilities are: Kafubu Water and Sewerage Company (KWSC) North Western Water and Sewerage Company (NWWSC) Southern Water and Sewerage Company (SWSC) Mulonga Water and Sewerage Company (MWSC) These projects are targeting more than 15,000 people with improved household sanitation services in low-income areas. Funding has been provided by the Government of Zambia, DANIDA (Danish International Development Agency), KfW, European Union and AusAID. Technical Assistance is provided by GIZ (German Development Cooperation). This fieldnote captures the DTF’s sanitation implementation approach and experiences during the implementation of these first four sanitation projects and focuses on faecal sludge management aspects in particular.

Learning from Alfred Nzo DM's Zonal Distribution Approach

Nzo, A.

Water Information Network (WIN-SA), South Africa

The Alfred Nzo District Municipality in the Eastern Cape is bounded by the Drakensberg escarpment and the Lesotho border in the west, the Indian Ocean in the east, the KZN District Municipalities of Sisonke and Ugu in the north and the Eastern Cape District Municipalities of Joe Gqabi (formerly Ukhahlamba) and OR Tambo in the south (Figure 1). When it was first demarcated in 2000 it comprised three local municipalities, namely Matatiele, Umzimvubu and Umzimkhulu. After the 2006 local government elections the latter was re-demarcated into Sisonke, and after the 2011 elections the local municipalities of Bizana and Ntabankulu (previously under the OR Tambo district) were incorporated into the ANDM. The population of the district has over the past decade therefore first decreased and now increased. Its present level is estimated at 801 344 people and 169 261 households.

The scope of work includes: 1) a comprehensive literature review to synthesize current knowledge about the interaction between women's menstrual management practices and sanitation systems, 2) detailed case studies in two urban locations, and 3) a randomized product dissemination and demand trial where women will be offered to opportunity to test and then choose among alternative menstrual management products. Goal(s): This study aims to understand: -The experiences of women in managing their menstrual periods, including the products that they use, their perceptions of the sanitation facilities they use, and how their periods may impact their daily routines. -Women’s preferences for alternative menstrual management products that may have less impact on sanitation systems. -The influence of women’s social networks on product adoption and other behaviours. Objectives: -Synthesize the state of current knowledge through a review of the literature on women’s perceptions and cultural beliefs around menstruation, and menstrual practices. -Understand the impact of menstrual practices on sanitation systems through a global survey of sanitation managers. -Document how menstrual products are disposed of in two contexts: Durban, South Africa and Bihar, India. Investigate the acceptability of a reusable silicon menstrual cup among adult women in two contexts: Durban, South Africa and Bihar, India. Understand determinants of, and barriers to, product experimentation and continued use, including experience of peers. -Test how prior use of a disposable menstrual product (sanitary pads) affects demand for a reusable product (the menstrual cup) through a randomized controlled trial in Bihar, India.

Open defecation without a toilet or latrine is among the leading global threats to health, especially in India. Although it is well-known that modern sewage infrastructure improves health, it is unknown whether a sanitation program feasible for a low capacity, poor country government could be effective.This paper contributes the first causally identified estimates of effects of rural sanitation on health and human capital accumulation.

Trends Shaping the Market for Urban Sanitation

Schaub-Jones, D.

2012

Stockholm Environment Institute, BPD Water & Sanitation

It does seem that the term sanitation as a business is gaining some momentum. Perhaps sanitation is not yet sexy, but it is certainly gaining more attention than it did a few years ago. This paper tries, by looking more closely at one specific sanitation market, to tease out some of the broader trends affecting the sanitation sector and, in particular, unsewered sanitation. It looks at how this market is structured, where value exists and how this is monetised and suggests how this market is evolving. It also looks at how outsiders are looking to support the development and professionalization of the market. This paper also addresses some broader trends that shape markets in unsewered sanitation. While a dramatic change in approach in developing countries is highly unlikely, even a marginal shift towards alternatives to centralised sewer systems could have significant ramifications for developing countries. In Africa at least, few countries have succeeded in putting in place sewerage networks of any great scale. Many inherited their networks at independence and these have not always been well maintained (never mind kept pace with rapid urbanisation). Yet attention to other forms of waste management has been minimal; mostly those ‘without’ have been left to fend for themselves. Research and development into alternatives has been minimal and when it comes to technical choices, engineering approaches and norms and standards, professionals in the sector have generally taken their lead from developed countries.

Further information and a discussion is available on the SuSanA discussion forum: http://forum.susana.org/forum/categories/98-resource-recovery-from-excreta-or-faecal-sludge/4209-biogas-generator-powered-by-self-sustaining-mixing-mechanism-frontier-environmental-technology-usa Goal(s): The goal of this project is to develop a high-efficiency biogas generator capable of producing the quantity of biogas and quality of effluent typical of advanced biogas generators, but without their inherent power or maintenance requirements. Objectives: (a) to develop a mixing device that uses the biogas generated from the lower portion of the biogas generator to automatically mix the generator content, without external energy input and mechanical moving parts; (b) to preliminary test the performance improvement of the biogas generator that integrates the self-mixing capability with the conventional biogas generators. How does it work? Overall, I have a mixing device within the reactor. This device collects gas bubbles from the lower portion of the tank. At a certain gas volume, the entire amount of the gas is released all together, creating a suction from the tank bottom and mixing the reactor. It uses the lifting power of the biogas bubbles created within the reactor therefore it does not need external power to drive it. Also, it does not have any mechanical moving parts, and all function is accomplished hydraulically. Therefore it is expected to be maintenance-free. Possible applications: We intend to use this unit for family use to replace old, large non-mixing digesters, because the old systems are so large that they have to be built on-site with causes lots of issues. Since our self-mixing units are small we can fabricate them in a central location to reduce cost and improve product quality. Major frustrations: Our project has a very good start but we were disappointed that we did not get follow up funding for continued development and testing. Since this technology is so different than conventional thinking it may take some time to understand. The majority of the work during the research is to make the self-mixing biogas generator mechanically functional and to prove the self-mixing concept. Therefore, the actual biogas data is very limited. I really wished to have more funding to continue this research with a more realistic reactor, but it did not happen yet. We are welcoming supports from funding agencies and collaborators to continue this work.
