*time
**the more convenient it is, the more people will use it
**20 seconds might be too long
**currently takes <1/2 second
*way to dose different sizes would be great
**should be simple enough so that people can walk up and figure out how to use it with no prior knowledge
*making it easy for people to know when to refill chlorine is a tradeoff with the time it takes to refill
*tamper-proofing would be great
**but consumable Cl is very cheap so not a ton of incentive to steal/dilute
*in a few months: 1000 dispensers deployed in Western Kenya - beginning summer, end of spring
**our changes etc can be part of this - affecting 500,000 people!!!
*water in these areas currently non-turbid, but eventually the dispenser will be deployed in locations with turbid water
**turbidity affects the Cl dose (usually 2x concentration)
*transporting is a big part of total costs
**especially CL
***SOLID CL (calcium hypochloride?) could reduce costs
****quality regulation more important - need good quality water to mix with solid Cl - lifespan is a function of water quality
****lasts at least 2 weeks, 1 month
****liquid Cl lasts for at least 2 months
*container size calibrated to last 1 month
*refilling: currently padlock - need to have key to check to see if it needs to be refilled
**sometimes there are a few days without Cl because the refiller is away and no one else can access it
**ideally we can find way to maintain security, but let people know when it needs to be refilled
*ideally: costs $50 and lasts longer than current model. BUT most important that it costs less, as many communities cannot afford now.
