Personalized testing kits for testing Residual Silver ion level at delivery points

Source

Source summary

Develop a low-cost portable kit for rural households to measure residual silver ions in a 100 ml drinking-water sample with a digital concentration display. Target low-level detection and laboratory-comparable accuracy, quick results, easy calibration and minimal training. Require durable operation under changing temperature/humidity, low maintenance, regulatory compliance, safe use/disposal and at least 24 hours per full battery charge. The source does not give a numeric silver limit.

Development of a suction based low-cost flush (with less water usage) for deployment in rural areas.

Develop an inexpensive suction-based toilet flush for rural settings with constrained water and costly conventional plumbing. Minimise water demand while keeping installation and upkeep simple and providing hygienic waste removal. The source specifies suction as the proposed mechanism but gives no numerical water-use target.

Personalized testing kits for testing Residual Chlorine level at delivery points

Develop affordable rural-household water tests with digital readings, quick results, simple calibration, low upkeep and at least 24 hours per battery charge. Although titled residual chlorine, the description explicitly covers separate chlorine, silver-ion and/or bacterial kits and references 100 ml sampling plus historical BIS chlorine/coliform criteria. Require durability under temperature/humidity variation and safe operation and disposal. These source-specified targets are not proof of compliance.

Personalized testing kits for testing Bacteriological contamination at delivery points

Develop an affordable, portable rural-household drinking-water test for E. coli and total coliform under JJM. Digitally report contamination in a 100 ml sample, targeting the source's BIS 10500:2012 criterion of nondetection. Seek laboratory-comparable accuracy, quick results, simple calibration and minimal training. Require low upkeep, resistance to rural temperature/humidity conditions, safe operation/disposal and at least 24 hours of operation per full battery charge. These are targets to validate, not certified performance.
