A serious initiative to scale up water chlorination in India

We really helpful a $38.8 million grant to Proof Motion to help the Indian authorities in offering clear water by establishing in-line chlorination in two states, Andhra Pradesh and Madhya Pradesh.

This isn’t a grant designed to immediately ship a service or commodity; as a substitute, Proof Motion will use the funding to work in shut partnership with state and native governments, offering technical help to help the supply of this system. Offering all rural households with entry to scrub, piped water is a significant precedence for the Indian authorities. In-line chlorination, which makes use of a tool to mechanically disinfect water by including chlorine because the water passes by a pipe, is a solution to make ingesting water protected.

We imagine this grant could not solely improve entry to chlorinated water within the states it immediately helps, but in addition encourage different states to undertake related practices. A core a part of this system’s principle of change is that governments in places outdoors the grant space could take up a program they may not in any other case undertake. That is the primary very giant grant we’ve made the place that’s been an necessary consideration. We expect the upside is unusually excessive—if profitable, this grant may ultimately result in tens and even lots of of tens of millions of extra individuals receiving protected water—nevertheless it’s additionally riskier than most of our grants, as there are a selection of how this system may fail to have the specified affect. Our hope is that this grant will scale back mortality and enhance well being at a really giant scale.

The remainder of this publish describes the significance of fresh water, the advantages of partnering with authorities, why we predict this chance has such a big potential upside, our estimate of this system’s cost-effectiveness, and a few of our uncertainties. You possibly can learn the complete rationale for the grant right here.

Why is clear water necessary?

Consuming contaminated water can result in intestinal infections which can be typically deadly. The proof we’ve reviewed means that enhancing water high quality additionally reduces mortality from causes indirectly linked to water high quality, similar to respiratory infections (extra right here).

We estimate that this program will scale back total mortality by about 4% amongst individuals reached with in-line chlorination. On condition that we anticipate this system could attain tens of tens of millions of individuals over the course of round a decade, the affect could possibly be big—our very unsure greatest guess is 75,000 deaths averted.

For an in depth evaluation of how we estimate the discount in mortality, see this part of our grant web page and this part of our analysis report on water high quality.

Why companion with the federal government, and why now?

In 2019, the Indian federal authorities took on an unlimited mission, Jal Jeevan Mission, with a mandate to convey clear, piped water to each rural family in India.

It’s difficult to arrange methods to make sure that water is not only accessible but in addition clear; in-line chlorination is a promising expertise to perform this. We expect that Proof Motion may also help improve the variety of households reached by in-line chlorination by offering help to the federal government for work like:

  • Putting in the optimum in-line chlorination units for every context (together with, e.g., selecting between electrical and non-electric units, and between units that use liquid chlorine and people who use chlorine tablets)
  • Designing efficient monitoring and analysis methods, and troubleshooting issues that come up
  • Coaching workers to implement in-line chlorination on the native stage
  • Establishing normal working procedures for putting in, sustaining, refilling, and monitoring the units

Jal Jeevan Mission is a significant nationwide precedence, and our sense is that the Indian authorities may be very concerned about working with Proof Motion to scale in-line chlorination.

Proof Motion additionally appears particularly well-placed to help this program. It has expertise scaling up water chlorination packages in Africa and is a pioneer in implementing in-line chlorination. Moreover, Proof Motion is already working with the Indian authorities to supply technical help (on school-based deworming and iron and folic acid supplementation packages, by Proof Motion’s Deworm the World and Equal Vitamin Entry packages, respectively).

What offers this mission such excessive upside?

This sort of partnership between a nongovernmental group and a authorities physique creates the chance to leverage authorities sources for increased affect. This grant is giant—$38.8 million—however is a small fraction of the general $44 billion dedicated by the federal government to Jal Jeevan Mission. Authorities funding of this scale means philanthropic help may be centered on offering technical help on the nationwide and state stage somewhat than on offering in-line chlorination itself.

We additionally see an thrilling chance of different states taking on in-line chlorination due to this grant. We count on Proof Motion to assist the federal government develop normal working procedures and monitoring and analysis protocols for operating in-line chlorination packages. As soon as these have been established, we predict it would turn out to be simpler for extra states to take up this system, and thus extra doubtless they’ll accomplish that.

One promising step in that path is that Jal Jeevan Mission requested Proof Motion to steer a Nationwide Symposium on Protected Water and Chlorination Initiatives and invited state-level water officers from throughout the nation to attend. Proof Motion has additionally participated in plenty of extra national-level trainings. These initiatives and others like them could make it extra doubtless that different states take up in-line chlorination, although we don’t but know whether or not this has had an affect. If different states take up this system, Proof Motion might be able to present related technical help in these new areas.

How cost-effective does this grant appear?

Our cost-effectiveness estimate for this grant is far more unsure than for our high charities. We used the cost-effectiveness estimate as one issue, however not the one issue, in our decision-making. We strongly weighed qualitative elements just like the obvious stage of presidency curiosity, Proof Motion’s enthusiasm in regards to the alternative relative to different packages it may tackle, and knowledgeable views on the plausibility of the idea of change.

The objective of influencing different states makes the idea of change for this grant completely different than for many of our grants. In our evaluation, about half the anticipated worth of the grant comes from the 2 states the place we’re funding Proof Motion’s work, and the remaining half is the anticipated worth of prompting different states to tackle in-line chlorination.

For this grant investigation, we devoted a variety of time to chatting with specialists, together with touring to India to talk with authorities officers and discussing the grant with over twenty exterior contacts. These conversations helped us sense-check our assumptions. For instance, we make assumptions about what number of extra individuals can be reached by in-line chlorination with Proof Motion’s help than within the absence of their technical help. The conversations additionally helped us higher perceive how coverage change happens in India.

Our greatest estimate is that this grant is 22x money—i.e., we estimate that every greenback spent on this grant will create as a lot worth as roughly $22 in unconditional money transfers to individuals residing in poverty. The anticipated worth of this grant is an extra 26 million individuals receiving chlorination for ten years; that determine contains subjective changes for each the upside mentioned above and drawbacks like the danger of this system being discontinued. Among the most unsure elements in our evaluation are mentioned within the subsequent part.

What are we most unsure about?

Our uncertainties are described in additional element on the full grant web page. Right here, we describe just some key questions.

What’s the impact of chlorination on mortality?

We now have a number of excellent questions in regards to the impact chlorination has on mortality normally, and on mortality in India extra particularly. Estimating this impact entails:

  • Reviewing experimental proof on the mortality discount in kids below 5.
  • Extrapolating that proof and contemplating observational proof to estimate an impact on mortality in individuals over the age of 5.
  • Contemplating knowledge on water high quality and diarrheal illness from India particularly, and reviewing proof on water contamination in neighboring international locations to assist triangulate.

We focus on these estimates in additional element on our grant web page. We’re fairly unsure about our estimates. For instance, we predict there’s a 50% probability that chlorination reduces mortality for all ages by someplace between 1% and seven% (and a 50% probability that it reduces mortality by kind of than that vary). If mortality had been diminished by 1%, this system would have a cost-effectiveness of 5x money, and if mortality had been diminished by 7% this system would have a cost-effectiveness of 37x money—so our assumptions right here have a huge impact on the underside line!

Will this system fail to get off the bottom or be discontinued?

We expect there’s a comparatively excessive probability (round 35%) that Proof Motion’s program is discontinued inside two years, primarily based on our basic understanding that technical help packages are sometimes discontinued. For this system to succeed, it would require authorities buy-in, infrastructure improvement, and the rollout of a brand new expertise. To mitigate the danger of discontinuation, we arrange “gates” that this system should move to ensure that us to proceed to supply funding. If this system is discontinued in Andhra Pradesh or Madhya Pradesh, we may even discover the opportunity of rolling present grant funding over to different states.

Will this program encourage different states to undertake in-line chlorination?

As talked about above, round half the modeled advantages of the grant come from the opportunity of different states implementing this system. Coverage change is tough to foretell, and we’re significantly not sure how doubtless that is. Our estimates are primarily based on Proof Motion’s expertise scaling up school-based deworming in India, which is a distinct sort of program (for instance, it doesn’t require establishing infrastructure) and subsequently could not predict outcomes for in-line chlorination.

How many individuals would entry chlorinated water within the absence of Proof Motion’s help?

Our estimate of the tempo of scale-up relies on historic tendencies of water remedy. Nonetheless, it’s doable the federal government’s curiosity in water chlorination will change sooner or later. For instance, curiosity could improve as individuals study in regards to the outcomes of a latest meta-analysis on the impact of water remedy, together with chlorination, on mortality.

We don’t understand how good our estimates are for the parameters described above. We expect it’s necessary to incorporate them in our evaluation in order that the judgment calls we’re making are express. As this system develops, we’ll be capable to study extra.


We look ahead to seeing what the Indian authorities and Proof Motion accomplish by this partnership. Our hope is that in-line chlorination might be adopted extensively and that its implementation might be long-lasting, permitting many tens of millions of individuals to entry clear water.
