Content Overview This module is supposed to give an overview of some decision-making approaches that explain how to chose an appropriate sanitation concept for a certain community. Household Centred Environmental Sanitation (HCES) Approach, the Ecosanres: Open Planning of Sanitation Systems Approach, the GTZ ecosan Project Steps, BORDA Community Based Sanitation Approach. K. Conradin

Implementing Sanitation and Hygiene: Assessing Needs Source: Hesperian Foundation (7)
8
Implementing Sanitation and Hygiene: Assessing Needs Health is not always the main reason why people want to have clean toilets, better water supplies, or improved hygiene. Other needs may include: Privacy: Safety Comfort Cleanliness Respect Source: (7) J. Heeb Source: J. Heeb
9
Planning for Sanitation Every person and every community has a way of dealing with sanitation: Taking about sanitation is necessary needs of men/women needs of children elderly disabled All stakeholders must be able to identify with the toilet Source: Hesperian Foundation (7)
10
Planning for Sanitation Small steps to sustainable sanitation Small, step-by-step changes are easier than big changes all at once. keeping wash water and soap near the toilet adding a vent to a pit toilet adding a hard, durable platform to an open pit etc… These small changes may then clear the way for more thorough and sustainable solutions Source: Hesperian Foundation (7)
11
Planning for Sanitation Prevent disease – it should keep waste and insects away from people Protect water supplies – it should not pollute drinking water, surface water, or groundwater. Protect the environment – ecological sanitation can prevent pollution, return nutrients to the soil, and conserve water. Be simple and affordable – it should fit local people’s needs and abilities, and be easy to clean and maintain Be culturally acceptable – it should fit local customs, beliefs, and desires. Work for everyone – it should address the health needs of children and adults, of women and men, as well as disabled people Source: Hesperian Foundation (7) Every sanitation method should fulfil the basic considerations listed below:

Planning for Sanitation Source: (9)
13
Planning for Sanitation Sanitation decisions are community decisions Because people have different sanitation needs, decisions about sanitation should be made by the people who will be most affected by those decisions. Community participation can make the difference between success and failure when a government or outside agency plans a sanitation program. Source: Hesperian Foundation (7)
14
Informed Choice Informed Choice is based on a full understanding of the costs and benefits of all available options. Who decides what service level the community will receive? How are decisions made (meetings, voting, representatives)? Are operation and maintenance responsibilities clear and presented to the stakeholders before decisions are made? Does the project provide qualified assistance to facilitate decision- making? Does the school make an informed choice to participate in the project?” Source: (5)
15
HCES: The Household Centred Sanitation Approach Source: (3) “The ‘Household-Centred Environmental Sanitation’ model is strongly based on the Bellagio Principles. It offers the promise of overcoming the shortcomings of business as usual because its two components correct existing unsustainable practices of planning and resource management. These components are: –Stakeholder at the core of the planning process: Direct response to the needs and demands of the user It is based on the following principles: Stakeholders are members of a “zone”, and act as members of that zone (“zones” range from households to the nation). Zones may be defined by political boundaries (for example, city wards and towns) or reflect common interests (for example, watersheds or river basins). Decisions: consultation with all stakeholders affected by the decision, in accordance with the methods selected by the zone in question
16
HCES: The Zonal Model of the HCES Approach Source: (3)
17
HCES: Principle of Minimizing Waste Transfer Circular System of Resource Management: minimize waste transfer across circle boundaries minimizing waste-generating inputs and maximum recycling/ reuse activities in each circle. emphasizes conservation (reducing imports) of resources, and the recycling and reuse of resources waste is a misplaced resource. Source: (3)
18
HCES: 10-step process
19
EcoSanRes: Open Planning of Sanitation Systems Ultimately: All factors influencing the sustainability of a sanitation system, local conditions, applicable regulations user preference must guide the choice of a sanitation solution. Open planning of sanitation systems attempts to have a cross-cutting approach in its five steps described below. Source: (8)
20
EcoSanRes: Step 1: Problem Identification “STEP 1: PROBLEM IDENTIFICATION Stakeholder identification Source: (8) Residents Planners and political decision makers Schools and commercial operations Land owners Contractors Farmers Community-based organizations Other stakeholders, such as neighbours with freshwater wells, people living downstream, etc. Engineers, both public and private Funding agencies J. Heeb
21
EcoSanRes: Step 2: Identification of Boundary Conditions “STEP 2: IDENTIFICATION OF BOUNDARY CONDITIONS Socio-economic patterns? cultural habits? Demand for improved sanitation? Willingness to pay vs capacity to pay? Legal framework? Which waste flows exists? What infrastructure is there? Location of nearby streams and lakes? Natural conditions (groundwater level, soil conditions, precipitation)? Amount and quality of the wastewater fractions? Successful sanitation schemes in neighbouring communities?” (8) J. Heeb
22
EcoSanRes: Step 2: Identification of Boundary Conditions system boundaries Where does the system begin and end? All wastewater fractions included? Management in a separate or combined manner? Does the system include other houses? Does the system include treatment or only collection and discharge to a larger system? important for cost calculations the definition of responsibilities J. Heeb
23
EcoSanRes: Step 3: Terms of Requirement STEP 3: TERMS OF REQUIREMENT (ToR) ToR should be comprehensive and include all factors needed to ensure sustainable sanitation in the actual context. all criteria need to be adapted to the actual case. In open planning organize the function requirements in two blocks, 1.FIRST BLOCK: primary functions: hygiene and disease protection, environmental protection resource conservation. 2.SECOND BLOCK: geared towards the user, userfriendliness, reliability, affordability responsibility and control are discussed. Balance between the two needs to be identified. Source: (8) J. Heeb
24
EcoSanRes: Step 4 & 5: Analysis of Possible Solutions STEP 4: ANALYSIS OF POSSIBLE SOLUTIONS Analysis of different sanitation solutions complying to the ToR, with respect to all criteria in the ToR feasible? appropriate? Presentation of at least three appropriate solutions to the community Explanation: why appropriate? Why not? STEP 5: CHOICE OF THE MOST APPROPRIATE SOLUTION Evaluation and comparison of alternatives Final choice by the future users Source: (8) J. Heeb

GTZ: ecosan stakeholders The stakeholder analysis aims to give an overview on the possible types of stakeholders who may be involved in a project. (I) Users of sanitation facilities: (II) Users of the recyclates: (III) CBOs (Community Based Organisation) and self-help groups (IV) NGOs Source: (10) J. Heeb

CBS: Community Based Sanitation (BORDA) CBS projects: holistic and demand responsive approach. Instead simply providing technical sanitation infrastructure, CBS-projects aim to improve hygiene behaviour and sanitation infrastructure in a more integrated and sustainable manner. Focus on poor and densely populated areas See 4-1_AppropriateTechnology_TUTORIAL.ppt Module for more details Source: (7)

WSSCC: Community Driven Development for Water and Sanitation in Urban Areas Community-driven improvements in provision Alternative means to support improvements in provision for water and sanitation Financing water and sanitation improvements through loans and subsidies Engaging with small-scale private water and sanitation providers Tools and methods that support community-driven improvements for water and sanitation See 4-1_AppropriateTechnology_TUTORIAL.ppt Module for more details This publication describes community driven initiatives and discusses their relevance for meeting the Millennium Development Goal (MDG) target for water and sanitation. It includes chapters on:
