What coordination models best scale shelter and sanitation in growing refugee camps?

[Scott_H]

I work for an NGO coordinating aid in a region experiencing a large-scale influx of refugees, and we're struggling with the logistical challenge of providing consistent shelter and sanitation as the population in temporary camps continues to grow faster than infrastructure can be built. The political dimensions are complex, but my immediate focus is on the practical delivery of services. For humanitarian professionals with field experience, what operational frameworks or coordination models have proven most effective for managing these dynamic scaling challenges while maintaining the dignity and safety of displaced populations?
