Solar powered ultrasonic sensor water level sms alert device

I am looking to provide water level alert devices to residents of small towns and cities in Nigeria so as to alert users on time of low water level in their storage tanks. The device would operate with solar and installed on top of the tanks. The device should be capable of sending an SMS alert for 20% water level. The range of the sensor should be 3-6m max. It needs to be mass produced and each piece should cost between $5-$15. Prototype should cost between $10-$60 max.

Preferrably, a China resident who has easy access to factories.
