Along with a brief explanation of why that 7 to 15 is important, and its variabilities (temperature, etc...). And simple version of how to treat water, or detect water borne illnesses.

And some basics about wells, karsks, etc...

And about "water rights" and an overview of what of the farmework and implications of that concept are at a local level.

All the dumb stuff in one place,

Makes any soldier capable of being a fairly decent first level responder.

Now back to the structure. If you had this Dummies book, can you also arrange that upstairs is somebody who can serve as the basic second level responder (has access to water table, soils maps, rain fall stuff to assist, support the first level responder, and a framework for him to get dumb things deployed like chlorine tablets and simple test kits, or to coordinate testing processes (a good civilian business/employment opportunity---one per district or something). Somebody somewhere to make sure that each of the first and second level responders are on track, and not, trhough too much of one strategy, marching off a cliff.

I've seen plenty of really simple diagrams for the hydro cycle, water tables, stuff like that. But how does a person in the field link to find out what actually applies where he is, what typical local systems and components to understand and target, what NOT to do (drill lots of wells and collapse the aquifer).

Water for Dummies

Then Schools for Dummies, Health Clinics for Dummies, and Electricity for Dummies, and you start to have all the pieces for a component approach, less first time learning, and more synchronization and planning/resource/logistics options.

Anyone building or maintaining a school system knows that you try to standardize all the parts, equipment and FFE (furniture, fixtures and equipment---desks, flourescent tubes & starters, chalk boards, etc...) in order to improve service and cut costs.

Same stuff is just basic to health clinics, etc..., better to have five that are identically equipped and easily resupplied, maintained, operated, than ten that are all different and won't be sustainable beyond a year or two.

And that standardization is the essence of training for teachers, clinic staff, and maintenance workers for wells, power, etc... Common systems and common equipment supply chains... Now you can plan, train, employ and manage....improving the service of local government the way local governments actually do it.
