Clay Pot Filter




Project Objective: To develop a more mobile way of filtering water that complements the immobile concrete water filter being used currently.

Light Cycle Project



Project Objective: To improve upon a cheaper and easier way of generating power using bicycles as the source of energy.


Bio Sand Water Filter Project


Project Objective:  To present and install a device that will provide purified water to the Haitian community as a whole, in the hopes that one day all of Haiti will have an alternative to their contaminated water supply.


Background on the problem:  Years ago, Professor Jay Meegoda of NJIT got wind of the serious water borne problem in Haiti.  The water in Haiti is highly contaminated, and this has resulted in many Haitians falling ill to ailments such as upset stomachs, diarrhea, dysentery, cholera, and typhoid, all in addition to contributing to a high infant mortality rate.  Forming EWB-NJIT, and consequently its first endeavor the Bio Sand Water Filter Project, has the potential to eradicate the vast majority of these water borne diseases, should it be widely implemented enough.


Solution:  Using materials available around Haiti, EWB-NJIT has come up with a simple solution which they have called the Bio Sand Filter (BSF).  Using a combination of sand, gravel, cement, a diffuser plate, and a variety of other simple materials, the BSF is an easy to construct household device, one which avoids the troubles of a single, complicated water system.  The BSF is therefore a device that can realistically be adopted and maintained by most all families in Haiti.


Outcomes/Next Steps:  There have so far been 25 families that have received their own Bio Sand Filters.  They have been functioning as well as projected, and as such, the next steps are to see to it that more BSF's are installed throughout more of Milot.  This will require funding for additional measures to reach out within the community to expand upon the project, in order to see that it is embraced within the town as a whole.


Arborloo Project



Project Objective:  To develop a sustainable latrine capable of collecting human waste in order to convert it into fertilizer through decomposition, as well as to capture methane gas emissions resulting from a byproduct of the process. 


Background on the Problem:  Waste management in Haiti has become a serious problem, and there are not enough ways to keep this waste in check, nor is there enough decent ways to keep their fields well supplied with fertilizer.  This waste contributes to disease, as well as lowers the overall quality of life.

Solar Water Heater Project


Project Objective:  To create a water heater capable of supplying sustainable heat to cleanse the water used at the hospital in Minot, Haiti.


Background on Problem: Hospitals in Haiti suffer from severely contaminated water, just as the rest of Haiti.  Unfortunately, treating patients with such bacteria-laden water can cause problems of its own, ones that many patients can not afford. 


Solution: EWB-NJIT has been hard at work on the design of a solar water heater that will enable a hospital in Milot the ability to heat its water using nothing but green solar energy, which will in turn decontaminate the water and allow for safer medical care of its patients.


Outcomes/Next Steps: Once the design of the heater is finished, a prototype must be made, cooperation with the Milot community for this project must be established, and then the device must be installed and maintained.  Down the line, if the prototype is successful, more may be created to service the other hospitals in Haiti.
