  1. Urban Sanitation systems – building on the Household Centred Environmental Sanitation approach (HCES) SEI/EcoSanRes 2 Workshop on: “Planning and Implementation of Sustainable Sanitation in Peri/Semi-Urban Settings – A Need for Development of Existing Tools” 25 - 26 August 2008, Stockholm Roland Schertenleib Swiss Federal Institute of Aquatic Science and Technology (Eawag) / W+S Consult

  2. Content • Development of the HCES planning approach • Main characteristics of HCES • Enabling environment for HCES • 10 step planning process • Validation of the HCES approach • Successes and challenges

  3. Basis for future approaches in ES • People and their quality of life should be at the centre of any environmental sanitation system • Solutions of ES problems should take place as close as possible to where they occur • Any ES system must be designed in such a way to balance economic with environmental good • Wastes, whether solid or liquid, should be regarded as a resource • ES systems should be ‘circular’ designed in such a way as to minimize inputs and reduce outputs • Problems relating to ES should be handled within an integrated framework, and this framework should itself be part of a wider system of integrated water resources, waste management and food production

  4. HCES Approach is based on …… The Bellagio Principles for sustainable sanitation: • Human dignity, quality of life and environmental security at household level should be at the centre of any sanitation approach. • In line with good governance principles, decision making should involve participation of all stakeholders, especially the consumers and providers of services. • Waste should be considereda resource, and its management should be holistic and form a part of integrated water resources, nutrient flow and waste management processes • The domain (zone) in which environmental sanitation problems are resolved should be kept to the minimum practicable size (household, community, town, district, catchment, and city).

  5. What is environmental sanitation? interventions to provide a hygienic environment Interventions to reduce people's exposure to disease by providing a clean environment in which to live, with measures to break the cycle of disease. Involves both behaviors and facilities which work together to form a hygienic environment. excreta management wastewater management solid waste management behaviours facilities stormwater drainage washing facilities control of disease vectors

  6. Water Supply and Environmental Sanitation Solid Waste Management Drinking Water Supply • WATER SUPPLY AND • ENVIRONMENTAL SANITATION • Healthy and productive life • Ecological integrity of aquatic systems • Protection of natural resources Drainage Hygiene Excreta and Wastewater Management

  7. Household Centred Environmental Sanitation (HCES) Approach … places the household and its neighbourhood at the core of the planning process … is a multi-sector approach: accounting for excreta management (sanitation), storm water drainage, solid waste management and water supply … is amulti-actorapproach: emphasising the participation of all stakeholders, beginning at the household/neighbourhood or community level, in planning and implementing integrated urban environmental sanitation services

  8. Nation District / Province Town / City Neighbourhood Household (I) (II) (III) (IV) (V) Main characteristics of HCES HCES is based … on the concept of ‘zones’, and solving problems within the ‘zone’ nearest to where the problems arise

  9. Main characteristics of HCES HCES is based … on the circular model, emphasising resource conservation and reuse (rather than linear model)

  10. Concept of zones with bottom-up and top-down component

  11. From linear to „reuse oriented“

  12. From centralized to decentralized centralized … ...decentralized

  13. Potential of decentralized sanitation systems Tailoringto local conditions Responsiveness to local demands Minimizes waste of freshwater for transportation Permits waste segregation at source Lower risks system fails Increases local wastewater reuse opportunities Permits stepwise development and investment of sanitation system

  14. Decentralized and tailored solutions

  15. Structure of the HCES Guideline • How to create an ‘Enabling Environment’ • 10-STEP planning process Need for a change Bellagio Principles HCES approach HCES planning GL Enabling Environment 10 STEP process What next?

  16. Enabling Environment • Elements necessary to support the application of the HCES approach: • Government Support • Legal Framework • Institutional Arrangements • Required Skills • Financial Arrangements • Information and knowledge management Need for a change Bellagio Principles HCES approach HCES planning GL Enabling Environment 10 STEP process What next?

  17. Government support Political will and support at all levels Objective: secure agreement that HCES should proceed in the program area; doesn’t have to be an unconditional endorsement of HCES by the government. Favourable national policies and strategies Ensure that the HCES approach does not contradict existing policies and strategies Need for a change Bellagio Principles HCES approach HCES planning GL Enabling Environment 10 STEP process What next?

  18. Legal Framework Many existing standards are inappropriate, but cannot be rejected by public sector officials (personal liability). Examples: • Service delivery standards • National and municipal codes (e.g. health or building codes) • Technical standards (water supply and sewer standards) ► Secure a moratorium on the application of existing standards to the program area ► Try to identify more appropriate standards ► Upgrade existing standards Need for a change Bellagio Principles HCES approach HCES planning GL Enabling Environment 10 STEP process What next?

  19. Institutional arrangements Institutional arrangements are required that suit the highly decentralised and zone-by-zone approach used in HCES Arrangements across zones: support of local organisations (providing the services) from organisations in larger zones with greater capacities, such as: • direct provision of services • technical assistance, capacity building, information dissemination Arrangements between institutions at municipal level: close collaboration between various organisations involved in environmental sanitation services Arrangements legitimising and supporting the participation of small-scale private sector entrepreneurs Need for a change Bellagio Principles HCES approach HCES planning GL Enabling Environment 10 STEP process What next?

  20. Required skills Effective training and communications, ensuring that all participants understand and accept the HCES concept, including its pre-conditions and implications, e.g.: • Householders must understand implications of different options to them, e.g. convenience, costs, O&M requirements, etc. • Professionals must be familiar with existing legal framework, regulations, codes, range of technical options etc. • Municipal officials must be reoriented towards a better understanding of the social, institutional, financial and other factors that have to be addressed (paradigm shift) • Private service providers must be trained in business management, bidding, analysis of market demand etc. ► resource centres, short courses, curricula development, etc. Need for a change Bellagio Principles HCES approach HCES planning GL Enabling Environment 10 STEP process What next?

  21. Credit and other financial arrangements Credit and other financial arrangements that facilitate household participation and community involvement Strong advocacy is required to convince different levels of government (from national to local) that: • HCES programmes require (initially) an increase in investment in the WATSAN sector, which have to be covered by increased budget allocation. • Allowance needs to be made for funding the full range of costs: administrative and hardware costs; software costs (e.g. training, social marketing programmes, O&M needs). • Local private initiatives must be supported through setting up of micro-credit schemes (rather than grants and subsidies). Need for a change Bellagio Principles HCES approach HCES planning GL Enabling Environment 10 STEP process What next?

  22. Information and knowledge management • Guidelinesare required, providing information on a comprehensive range of technical and software options, addressing questions such as: • benefits and limitations of different technical options • user friendliness • impact on environment, potential for resource recovery • traffic and land use implications • potential for income generation • impact on service for the poor • ... • Basis for locally developed guideline: “Compendium of Sanitation Systems and Technologie”, ‘state of the art’ texts, national and regional resource centres, academic institutions, experienced sector professionals etc. Need for a change Bellagio Principles HCES approach HCES planning GL Enabling Environment 10 STEP process What next?

  23. The 10 STEP Process Need for a change Bellagio Principles HCES approach HCES planning GL Enabling Environment 10 STEP process What next? • Request for assistance • Launch of the planning and consultative process • Assessment of the current status • Assessment of user priorities • Identification of options • Evaluation of feasible service combinations • Consolidated UESS plans for study area • Finalising of consolidated UESS plans • Monitoring, evaluation and feedback • Implementation

  24. The 10 STEP (iterative) Process Need for a change Bellagio Principles HCES approach HCES planning GL Enabling Environment 10 STEP process What next? • Request for assistance • Launch of the planning and consultative process • Assessment of the current status • Assessment of user priorities • Identification of options • Evaluation of feasible service combinations • Consolidated UESS plans for study area • Finalising of consolidated UESS plans • Monitoring, evaluation and feedback • Implementation

  25. VALIDATION SITES:

  26. Successes • Forum to meet local and other authorities • Formulation of community priorities especially in environmental management • Discussion of valid options & prioritization • Real ownership of interventions • Willingness to invest and to address priorities step by step • Sanitation as an entry point to community development !

  27. Challenges • Sometimes priorities not high on local authorities’ agenda • Setting high expectations amongst communities • The communities tired of planning processes and searching for solutions • Issues of land tenure and investment

  29. One-for-all solution in cities with highly heterogeneous physical and socio-economic conditions ??

  30. Insecure tenure High settlement densities Main challenges in planning for sustainable environmental sanitation systems Extreme socio-economic heterogenity High growth rates Unplanned and informal settlements Low funding priority

  31. The conventional planning approach • In the conventional planning approach, utility planners & engineers develop demand projections based on demographic and economic indicators (e.g. Maser Plans) • Infrastructure planning and service delivery continue to be supply-driven with a high degree of centralised control, little local accountability and low end-user involvement • The supply-driven model is a top-down approach, built around bureaucratic mechanisms and implemented by govt bureaucrats and engineers.

  32. Failures of theconventional planning model • Inflexibility in form and content • Procedures to amend plans are bureaucratic • Restrictive nature of master plans • Regulations and legislation favour planning of centralized sewerage systems – carry with them technology lock in…
