Enquiry on Small Scale Online Water Treatment Options for Rural Water Supply Systems, for Calcium & Turbidity removal

What would be your recommendations for introducing non-conventional water treatment units in the spring fed gravity water supply systems in hilly/himalayan terrain, as shown in the youtube link below?

I am asking ​this question ​with a view to ​know about the ​latest ​technologies ​and updates on ​small-scale ​water treatment ​units for rural ​water supply ​projects. The ​major water ​quality ​parameters of ​concern in the ​spring source ​water are ​calcium, ​turbidity (in ​rainy season) ​and bacterial ​contamination.​

Your ​suggestions ​would be ​heartily ​welcomed.​
