Eliminate vacuum aspirators

Problem: Vacuum aspirators consume about 15 liters per minute and there are often vacuum pumps available for the same task. In water starved regions this does not make sense.

Solution: Use vacuum pumps that are commonly available in research settings. Ask your colleagues for one if not readily available.

Cost: This will save 900 liters per hour of drinking water. Mechanical vacuum may be more reliable and stronger.

Benefit: Some inconvenience in finding or purchasing a pump.
