Reblog Unpacking the Drivers of WASH Sustainability
In Nov 2019 I highlighted several water/ sanitation/ hygiene ex-posts happening at USAID’s E3 Water Bureau. They’ve just come up with a synthesis, which is important, both in learning and transparency for accountability. Kudos! My only quibble is that we don’t know the full scale after only 6 very different ex-posts.
The authors Jones & Jordan’s overview: In its evaluation series, USAID looked back at the results of six water, sanitation, and hygiene (WASH) activities to inform future USAID investments in the sector and to better understand the long-term impact and sustainability of its interventions several years after projects close. Here: https://www.globalwaters.org/resources/blogs/unpacking-drivers-wash-sustainability
The water, sanitation, and hygiene (WASH) Ex-Post Evaluation Series represents a key milestone in the Agency’s ongoing quest to unpack the drivers of sustainability within our WASH programs. The commitment, made in the first USAID Water & Development Strategy (2013–2018), came in the wake of headlines about high rates of nonfunctional water systems in partner countries where USAID has long invested. At that time, many governments and development partners were grasping for similar answers, and a number of sustainability assessment tools emerged. For its part, the Agency pursued a multi-pronged approach that focused on: 1) measuring progress towards sustainable outcomes (such as through the development and application of the Sustainability Index Tool with Rotary International); 2) gaining a better understanding of the drivers of long-term outcomes through this WASH Ex-Post Evaluation Series; and 3) testing new ideas, approaches, and tools to strengthen the local systems that can deliver WASH service sustainability through the Sustainable WASH Systems (SWS) Learning Partnership.
The Agency, together with its development partners, has achieved staggering results in terms of delivering first-time water and sanitation access to people the world over. Since 2013, USAID has helped roughly 25 million people gain access to at least basic drinking water services and 18 million people gain access to at least basic sanitation. Together with partners, USAID has mobilized almost $100 million in new funding for the sector and supported nearly 17,000 communities become open defecation free.
Yet the results of this ex-post series are sobering. Despite tremendous achievements within the life of our programs, they have largely not endured. This is especially the case in countries and communities with the highest levels of poverty at baseline, where the Agency’s resources are needed the most. Rural water systems that, at activity close, delivered safe water to households have fallen into disrepair. Basic latrine ownership and use have dwindled. Communities certified as open-defecation free are backsliding, and gains in handwashing have not been sustained.
The series did reveal some programming bright spots. Where USAID invested in providing technical assistance to committed government partners and utilities, gains in service provision and local capacity were sustained, with local actors taking up and expanding upon best practices introduced during activity implementation. Often these successes endured in countries and communities that had higher levels of capacity at the outset. However, the successes in these contexts demonstrate important lessons about investing time and resources into partnering with local institutions and focusing on plans for management of services, not just first time access.
In the course of the roughly 15 intervening years since most of the activities evaluated in this series were designed, the sector has evolved. For instance, in resource-constrained environments, the sector is now coalescing around facilitating the development of professionalized support to community-managed rural water schemes in various forms, rather than expecting voluntary committees to manage essential services alone. Additional approaches beyond community-led total sanitation, including smart subsidies and market-based sanitation, are seen as necessary to move households up the sanitation ladder, and are being applied through USAID programming. And the Agency is shifting its WASH social and behavior change programming to more holistic approaches that address emotional drivers, convenience, and social norms to modify intractable behaviors rather than communication or health promotion alone. The WASH Ex-Post Evaluation Series validates why those shifts were essential.
All those with a stake in promoting lasting development gains in the sector need to internalize these findings and take a long look in the mirror. USAID has and is seeking to do better. First, under the USAID Water and Development Plan (2018–2022) in support of the Global Water Strategy, USAID codified its commitment to sustainability with the goal of increasing the availability and sustainable management of safe water and sanitation, and an emphasis on improving the underlying governance, finance, and management of water resources that underpin sustainability. Second, the Agency has issued a set of technical briefs that provide new guidance on important topics for developing and implementing WASH activities, as well as recommendations for activity design, implementation, and monitoring. Third, USAID has launched the Water Security, Sanitation and Hygiene Implementation Research Agenda that identifies and prioritizes sector-specific research questions to close lingering evidence gaps directly related to accomplishing USAID’s goal of increasing access to sustainable water and sanitation services. Finally, the Agency is rethinking its approach to sector targets and key performance indicators in its solicitations, recognizing that targets can cause perverse incentives to undermine sustainability from the outset. Doing so underscores the Agency’s commitment to sustainability and its willingness to be held accountable to deliver against those results.

Sustaining “Sustainable Development”?
As a global development industry, we have almost no evidence of how (un)sustained the outcomes or impacts of 99% of our projects because we have never returned to evaluate them. But from early indications based on the ex-posts, we have evaluated 2-20 years after donor departure it is, learning from what was and was not sustained is vital before replication and assuming sustainability. Most results taper off quite quickly, showing 20-80% decreases as early as two years post-closure and donor exit. A few cases of good news also appear, but more trajectories falter and fail than rise or remain. Sustainability, then, is not a yes-no answer, but a how much, yet too few ask… hence if they were, resilient, they are less so, or even not at all, now.
At Valuing Voices we focus on the sustainability of projects after external support ends. Still, those projects are also dependent on the viability of the environment in which they are based. As Andy Rowe, an evaluator on the GEF’s Adaptation Fund board, noted at IDEAS’ Conference in Prague late 2019 , a need for sustainability-ready evaluation to help us know how viable the resources are on which so many of our projects rest . He states, “the evaluation we have today treats human and natural systems as unconnected and rarely considers the natural system”. He goes on to differentiate between biotic natural capital (air, water, plants, and trees) and abiotic natural capital sources (fossil fuels, minerals, and metals, wind, and solar).
How much are projects designed assuming those resources are and will remain plentiful? How often do we evaluate how much our projects drain or rely on these environmental elements? Many projects are required to do environmental compliance and safeguarding against damage at project onset . Others, such as agriculture and natural resource management or water/ sanitation, often focus on improving the environment on which those activities rely, e.g., improving soil or terrain (e.g., terraces, zais), planting seedlings, and improving access to potable water for humans and animals. Still, many projects ‘assume’ inputs like rainfall, tree cover, solar power, or do not consider the sustainability of natural resources for the communities in which they intervene. Examples are both those that rely on natural systems as well as those supposedly beyond them, e.g., enterprise development, education, safety nets, etc. Yet many enterprises, schools, safety nets do rely on a. viable environment in which their participants trade, learn, and live, and all are subject to the growing climate change disruptions.
Why is this urgent? The OECD/DAC reminds us that “Natural assets represent, on average 26% of the wealth of developing countries compared to 2% in OECD economies” . Unless we protect them and address the demand for natural resources, demand will far outstrip supply. “By 2030, an additional 1 billion people are expected to live in severely water-stressed areas, and global terrestrial biodiversity is expected to decline an additional 10%, leading to a loss of essential ecosystem services. By 2050, growing levels of dangerous air emissions from transport and industry will increase the global number of premature deaths linked to airborne particulate matter to 3.6 million people a year, more than doubling today’s levels. Failure to act could also lead to a 50% increase in global greenhouse gas emissions by 2050, and global mean temperature increases of 3-6°C by the end of the century, in turn contributing to more severe and sometimes more frequent natural disasters… [so] reconciling development with environmental protection and sustainable resource management is broadly agreed as a central concern for the post-2015 development agenda.”
When we return to projects that are a mix of behavior change and environment, we find a wide range of results:
- Some projects, such as JICA Vietnam’s water supply and irrigation infrastructure reached 80% of the final results two years later . And while the pilot projects were worse off (as low as 28% of irrigated hectares), longer-standing projects sustained as much as 72% of final results. While such agricultural development assumes continued water supply and access, does it evaluate it? No.
- Some can define what ex-post lessons are more narrowly as functioning mechanisms: New ex-posts of water/ sanitation showed better – but still mixed results, such as USAID Senegal’s . “While a majority (63 percent) of the water points remained functional, the performance varied significantly based on the technology used. Of the different technologies, the Erobon rope pumps performed poorly (27 percent functional), while the India Mark (74 percent functional) and mechanized pumps (70 percent functional) performed the best.”
- Some projects that include environmental considerations illustrate our point by only focusing on behavior change as this sanitation/ hygiene ex-post from Madagascar did, where results fell off precipitously three years ex-post but without considering water supply or quality much .
- There can be useful learning when one combines an evaluation of both types of sustainability (ex-post and environmental). A JICA irrigation project in Cambodia shows that when irrigation canals were mostly sustained over the five-years ex-post, they could serve increasing needs for land coverage and rice production . The area of irrigated fields at the national level in 2010 reached the target, and the irrigated field area has since continued to increase in most areas. Even the largest drop [in area irrigated] post-closure was only 11%. They reported that the unit yield of rice at the end-line survey in 2012 at 11 sites was 3.24t/ha (average) versus 3.11t/ha of unit yield of rice at the ex-post evaluation in 2017, which [almost] maintains the 2012 level. The ex-post showed that “continuous irrigation development in the said site can be considered as the main reason for the increase in land area. Securing an adequate amount of water is an important factor in continuously improving rice productivity.” The research also found that 81% of agricultural incomes as a result of the irrigation had increased, 11% stayed the same, and 8% had decreased. Again, this looks to be among the most resilient projects that, based on ex-post research, included environment which was also found to be as resilient as the livelihoods it was fostering.
- Sometimes more bad than good news is important when tracking environment and ex-post sustainability: Food for the Hungry, ADRA, and CARE Kenya found that unreliable water supply reduced the motivation to pay for water, threatening the resources to maintain the system . What improved prospects of sustainability understand why communities could not sustain water and sanitation results based on willingness-to-pay models, as well as water being unavailable. Further, a lesson the organizations ideally learned was that “gradual exit, with the opportunity for project participants to operate independently prior to project closure, made it more likely that activities would be continued without project support.” So the question remains, what was learned by these organizations to avoid similar bad results and improve good, resilient results in similar circumstances?
Neither sustainability nor environmental quality can be assumed to continue nor to have positive results. Both are extensively under-evaluated, and given climate change disruptions, and this must change. Rowe concludes: “Climate change is a major threat to the long-term sustainability both attacking the natural systems (e.g. lower rainfall or higher floods, worse soil quality, increasing pests attacking crops, disappearing fish stocks, microplastics in our air and water, increasing sea levels from melting glaciers, worsening public health etc.) and destabilizining our Earth’s regenerative capacity. Fortunately, technical barriers do not prevent us from starting to infuse sustainability into evaluation; the barriers are social and associated with the worldview and vision of evaluation.”

Learning from a river of ex-post project evaluations and tools… Thanks USAID!
Dear ex-post aficionados. It’s raining ex-post project evaluations. Here’s hoping learning from such evaluations in water/ sanitation, maternal/child health and even capacity building/ peacekeeping, and their number increases!
1. WATER/ SANITATION & HYGIENE:
USAID has a series of six ex-post evaluations of the water/ sanitation and hygiene sectors since 2017! What is exciting is that they are also looking to the future. These evaluations will “provide insight into what happens after an activity ends, and how to mitigate challenges in future programming, potentially. The series will inform USAID’s WASH activity design and implementation and contribute to a larger sector discussion on achieving sustainability.”
The E3 water division (Water CKM ) took sustainability on as their strategy and have made great strides these last two years. They have done five ex-post project evaluations, cited below, and MSI has completed one more wat/san/ hygiene ex-post evaluations, specifically:
Madagascar Rural Access to New Opportunities for Health and Prosperity (RANO-HP) – Published June 2017
The first evaluation in the series explores the sustainability of the sanitation and hygiene components of the RANO-HP activity, implemented in 26 communes from 2009–2013.
Indonesia Environmental Services Program (ESP) – Published August 2017
The second evaluation in the series examines the sustainability of water utility capacity building, microcredit, and financial outcomes associated with the ESP activity, which was implemented from 2004–2010.
Ethiopia Millennium Water Alliance (MWA-EP) – Published May 2018
The third evaluation in the series examines the long-term sustainability of outcomes related to rural water point construction, rehabilitation, and management, as well as participatory sanitation and hygiene education and construction related to the MWA-EP activity, implemented in 24 rural districts between 2004–2009.
Financial Institutions Reform and Expansion–Debt and Infrastructure (FIRE-D) – Published September 2018
This evaluation is the fourth in the series. It examines how urban water and sanitation services in India have changed since FIRE-D closed and to what extent policies, practices, and financing mechanisms introduced through FIRE-D have been sustained.
Millennium Water and Sanitation Program in Senegal (PEPAM/USAID) – Published July 2019
The fifth ex-post evaluation in the series looks at the PEPAM project (Programme d’Eau Potable et d’Assainissement du Millénaire au Sénégal), implemented from 2009–2014 to improve sustainable access to WASH in four regions of Senegal.
USAID-funded by MSI: USAID/Ghana’s Water Access, Sanitation, and Hygiene for Urban Poor (WASH-UP)– published Nov 2018
Also USAID and Rotary International developed a WASH Sustainability Index Tool, “to assess a WASH activity’s likelihood to be sustainable according to the following factors: availability of finance for sanitation; local capacity for construction and maintenance of latrines; the influence of social norms; and governance.” This is similar to what we learned from USAID/ FFP/ Tufts/ FHI360 12 ex-posts that resources, capacities, motivation and linkages (aka partnerships, including governance) are vital to sustaining outcomes and impacts.
It will be interesting to see whether they examine the other ex-posts for excellent lessons, as they have the Senegalese evaluation:
- “Whether or not to subsidize sanitation access …Based on this evaluation’s findings and exploration of the literature, subsidies can help improve the quality of household latrines, but increasing use of those latrines remains a challenge.
- In contrast, CLTS (a nonsubsidized approach) is often credited with increasing use of unimproved latrines, but serious questions linger about quality and long-term sustainability of the latrines built after CLTS triggering, particularly as it relates to moving up the sanitation ladder. This evaluation… provides the opportunity to examine the potential value of a hybrid approach….
- The handwashing results suggest that low-cost, low-quality handwashing stations such as tippy taps do not lead to sustained behavior change. It may be worth considering hygiene investments that reduce the behavior change burden on targeted beneficiaries.
2. MATERNAL/ CHILD HEALTH & NUTRITION:
“Sustainability of a Community-Based CHOICE Program to Improve the Health and Nutrition Status of Mothers and Infants in Indonesia,” The report focused on whether the USAID-funded CHOICE program had left sustainable impacts: improving the health and nutrition status of children under the age of five, as well as the health status of pregnant and lactating women and mothers or caretakers of young children in the Pandeglang District of Indonesia. “After examining the data collected from the PSS, the researchers found that there were significant improvements in many indicators—such as births attended by skilled personnel, the treatment of diarrhea, and the nutritional quality of food fed to infants—in the six years after the CHOICE program ended. However, despite these improvements, the researchers found no significant statistical differences between villages that received the CHOICE program interventions and comparison villages, which did not. This speaks to using such a comparison methodology to focus on actual contribution and rule out the “rising tide lifts all boats” phenomenon.
3. CAPACITY DEVELOPMENT & PEACEBUILDING:
USAID’s Regional Office in Thailand evaluated its capacity building and peacebuilding program 1.5 years ex-post. While civil society was strengthened and there were inroads made on peacebuilding, “many interventions initiated during Sapan did not continue post-Sapan, although some did remain. For example, “stakeholders cite evidence of continuing to use some governance tools in local governance related to service delivery [although] because of limited financial resources after Sapan ended, they had to change some of their interventions and reduce the range of people they could include. There are lessons for whose capacities are built, two-way feedback loops with local partners, using local organizations such as universities to sustain training, planning sufficient time for partners to internalize training lessons, etc.
4. USAID FUNDED GUIDANCE:
‘Impact Evaluations’ have a new focus on long-term impact, rather than effectiveness during implementation (which was at least the original intent of impact evaluation in the 1980s)! In September 2018, USAID and Notre Dame issued a Guide for Planning Long-term Impact Evaluations as part of the Utilizing the Expertise of the ERIE Program Consortium. The guide covers the difference between traditional impact evaluation designs and data collection methods and how to apply them to long-term impact evaluations (LTIE). It also shares examples across a range of sectors, including later evaluating past impact evaluations, which ended before final evaluation.
Finally, in new 2018 USAID guidance, ex-post evaluation is clarified as the source of the sustainability of services and benefits. USAID clarifies that “questions about the sustainability of project services and benefits can be asked at any stage, but must usually be adjusted to take evaluation timing into account. Thus, for example, in a mid-term evaluation, a question about the existence of a sustainability plan and early action on that plan might be appropriate. An end-of-project evaluation could address questions about how effective a sustainability plan seems to be, and early evidence concerning the likely continuation of project services and benefits after project funding ends. Only an ex-post evaluation, however, can provide empirical data about whether a project’s services and benefits were sustained.”
Such richness that we can learn from. Keep the momentum going on the 99% of all global projects yet unevaluated ex-post, and change how we fund, design, implement, monitor and evaluate global development projects!
