Accessing clean water is still a struggle for many people throughout the world. In areas devastated by natural disasters, it can take years for the infrastructure to be rebuilt. Makeshift water piping has been a massive undertaking in Nepal especially where an earthquake devastated the area a year ago. Organizations such as [https://www.fieldready.org/ Field Ready] are hard at work making sure water supply systems in the area are sanitary and helpful for those who need it. The T-fitting module was specifically requested by Field Ready to join hoses in the field to allow for more pipes to be ran while the entire system staying sanitary.

Accessing clean water is still a struggle for many people throughout the world. In areas devastated by natural disasters, it can take years for the infrastructure to be rebuilt. Makeshift water piping has been a massive undertaking in Nepal especially where an earthquake devastated the area a year ago. Organizations such as Field Ready are hard at work making sure water supply systems in the area are sanitary and helpful for those who need it. The T-fitting module was specifically requested by Field Ready to join hoses in the field to allow for more pipes to be ran while the entire system staying sanitary. The request Source can be found here.
