Special Factors:

This is a very unique research project that was done in Northern Uganda to guide in the planning and design of ecological sanitation systems to improve the sustainability of such systems. This was carried out in an effort to understand how to reduce morbidity rates, and improve economic and environmental sustainability as a whole.

The researcher used a modified version of the Visual Preference Survey™ (VPS) often used in urban planning. The VPS was proven to be useful in third-world development projects.

The researcher requested and received funding to travel and perform the study. It proved challenging in the sense that the researcher had only one opportunity to collect data.

Significance:

This is a worthy project because of the following:

• It is important to understand the culture before making design decisions.

• Ecological sanitation is a regenerative system with a low ecological footprint.

• Ecological sanitation is more adaptable to the environment than a waste water treatment system.

• There are many opportunities for landscape architects to be involved in developing countries.

The global concern:

Sanitation and open defecation practices are a major concern in developing countries. Many people die in these countries from unsafe sanitation systems that lead to contaminated food and water supplies (Lamichhane, 2007).

Introduction:

World Health Organization and United Nations are working to resolve the global issue:

The World Health Organization (WHO) states that morbidity rates could be reduced through improvements in sanitation. The WHO and United Nations see the problem as so critical that the United Nations has placed the sanitation issue as a millennium development goal (United Nations, 2000; McConville & Mihelcic, 2007)

The United Nations is not on track to meet the millennium development goal (United Nations, 2009).

Ecological sanitation is a sanitation system that by hygienic recovery, takes human excreta and turns it into something of use and value for its nutrients as well as minimizes the risk of environmental pollution and threat to human health (Duncker, Matsebe, & Moilwa 2007; Heinz-Peter & Jurga, 2007).

Key findings from other literature:

People all over the world have been discussing the limitations of natural resources (Landergraber & Muellegger, 2005).

Over ninety percent of sewage in developing countries goes untreated (Landergraber & Muellegger, 2005).

In rural areas with low population density a decentralized system where ecological sanitation can be effectively employed is needed for the system to be sustainable (Landergraber & Muellegger, 2005).

Septic systems or pits can be a problem as they fill up, and most owners do not have the financial means to empty them. In a rural setting, it may be possible to dig additional pits, but the cost involved still is not practical (Austin & Van Vurren, 2001; Austin, Duncker, & Matsebe, 2005).

Duncker suggests that local authorities should conduct surveys to conceptualize the needs, priorities, practices as well as socio-economic and cultural characteristics of the community before the beginning steps of implementation occur. Duncker goes on to say that such sanitation projects as the dry toilets should not only meet the needs of the community and existing practices but should suit the cultural norms and needs of the community members (Duncker, 2006).

This is the main part of the literature review that points out the need for surveys to be conducted.

The survey results were separated into two groups, the Restoration Gateway employees and the non-employees (other community members). This was done because the employees are familiar with flush toilets and many of the non-employees are only familiar with pit toilets. The researcher wanted to see how this difference affected their responses.

These are the findings on each of the categories from the Visual Preference Survey™ and respondent comments. The VPS results were compared by looking at the average score for each image. A t-test was performed on each pair for significance by using the p-value.

Privacy: Images of the toilets with no enclosure received a lower score than the enclosed latrine. The comments explained that open defecation is shameful, unhygienic, and that latrines should have a door to ensure privacy.

Placement: The closer a latrine was placed to a home or community the lower the score. Comments indicated that latrines should not be too close nor too far away from the dwellings. Also, it is unhygienic to have a latrine next to the home because of odor, flies, and disease.

Type (sitting or squatting):The sitting toilet received a higher score than the squatting toilet.In one of the images where the sitting toilet appeared to be unhygienic the squatting toilet had a higher score. In conversation with the participants some of them indicated that sitting on a toilet is not clean.

Type (portable or fixed ): The fixed toilet images received a higher score than the portable bucket toilet. The bucket toilet was provided as an “in home” most affordable option for the community. Comments showed that the bucket toilet is not a good option for children. Nonetheless, one comment stated wanting to learn how to use the bucket toilet.

Type (high or low): The high latrine scored slightly higher than the low latrine. Comments stated that the slab should be high enough to prevent flooding. Those familiar with ecological sanitation gave a higher score for the raised latrines. This could be because the raised latrine is an indication of a ecological toilet.

Gender: The gender labeled latrines received a higher score than the non-labeled latrines. Comments stated that latrines should be gender labeled. Men and women had no significant difference between their ratings.

Category Design recommendations

Privacy (Open or enclosed)When designing a latrine the privacy of the user should be highly considered. Users in this region desire a latrine that is enclosed with a locking door.

Placement (Near or far)Respondents did not like the pit latrines close to the house. When building pit latrines they should be placed some distance away so that odor and flies do not affect residents. An adjoining system may be possible if homeowner understands it is hygienic and flies would not be an issue.

Type (Sitting or squatting)Respondents prefer the sitting toilet over the squatting toilet. However if designing a public system where maintenance could be a concern, users may prefer a squatting toilet.

Type (Squat dry or squat flush)Both types were positive. Water shortages and economic feasibility needs to be considered when installing a flush system, particularly in rural areas.

Type (Portable or fixed)The fixed toilet was preferred over the portable bucket toilet. Through education and experimentation a bucket toilet may be possible. However, respondents prefer a more substantial system.

Type (High or low)Both types received high scores. Flooding can be a concern when designing a system with a low floor. The raised floor improves accessibility for using the composted waste.

Gender (Labeled or non-labeled) Respondents prefer latrines to be clearly labeled indicating male and female.

Gender (separate or unisex)Respondents prefer a gender separated system over a single unit. When possible a gender separated system should be built for public systems.

Final Conclusion:• Northern Ugandans are willing and capable of adapting ecological

sanitation systems through further educational training.

• Although the VPS was critical in respect to understanding the design preferences of sanitation systems, the comments from the respondents were the key to drawing this conclusion.

Respondent Comments:• Overall 62% (n=92) of the respondents left comments after completing

the survey.• 29 of the comments stated that they are interested in learning about

Ecological Sanitation and like the idea of using human waste for agriculture. In addition, some stated that they would prefer using Ecological Sanitation over other systems.

• 2 comments that were stated showed to have some concern for Ecological Sanitation.

At first glance one may not understand how the design of ecological sanitation plays into the field of landscape architecture. However, they are closely connected in many ways. This study took a close look into the perception of a people group and their culture. This is one of the first steps in a design process and it is often left out. This process is an important part of all design and planning fields. It is crucial for a designer to truly understand what a culture needs and how to meet those needs from a design standpoint. Many projects are unsuccessful when culture is not considered in the design process.

Although this project was specific to a people group in Uganda, the same methodology with a different topic could be applied to assist in the design of spaces in Mississippi where there is a deep culture and heritage. The structure of this methodology is not limited to sanitation systems only, but could be a model method used by landscape architects in community design for finding preferences for house types and common areas, parks and recreational spaces, campus planning, etc. By using a visual preference survey, language and cultural barriers are minimized.

Many projects are strengthened when people from different backgrounds can participate in the planning process. The use of Preference Surveys provides opportunity to receive opinions from the public creating a sense of pride, ownership, and public acceptance.
