Engineering Solution for dengue in Yemen has been working on coming up with three solutions on how to tackle dengue fever in Yemen. After doing extensive research we came up with three solutions, which are the filtering lid, chlorine tablets, and the solar power propeller.
Solar power propeller: A new generation of mosquitos can be made every 14 days. The only necessity for the mosquito’s life cycle is still water. The female mosquito lays her egg is still standing water and that is the place of development for an egg to adult mosquito. The solar-powered propeller is placed in the bottom of water storage containers and create a light constant current in the water so the female mosquitoes are unable to lay their eggs. Thus, removing an entire breeding ground for every container with a solar power propeller.
Filtering lid: The filter will reduce turbidity in the water, thereby maintaining sediment zones in the tank (whereas if the incoming water from the rainfall will pour straight into the top of the tank, water will stir during every rain event and become murky). Sedimentation will be most heavily concentrated on the very bottom and on the very top of the water, so if we can reduce turbidity in the water and draw the water from the middle of the water level (using a floating intake filter or an installed pump filter connected to the lid), we’ll get the cleaner water. Mosquito-proof screens are best suited to stopping mosquitos entering our tank or bucket through rainfall overflow. The filtering lid will be placed on the bucket in order to filter out the rainwater to create cleaner drinkable water while also keeping the mosquitoes out of the bucket. The top of the filtering lid will have a circular mesh net that will prevent mosquitos from coming into contact with the water and stop the egg/larvae development
Chlorine Drops: Mosquitos will not breed in chlorinated water. We would distribute chlorine drops to the people so they can add drops to their drinking water. Eight drops of 6% bleach are needed to purify a gallon of water. Chlorine is a cost-effective solution and safe for consumption so long as appropriate measurements are used, with appropriate education on the use of chlorine to purify water a significant number of the mosquito population could be reduced.
After doing the matrix we came to an agreement that we will focus on doing the Solar Power Propeller because based on our calculations the solar power will be more cost effective and it will be able to get the job done.
