VEV’s commodity chain is fairly straightforward. The majority of the parts VEV uses for the repairs are manufactured locally by the company itself. In fact, only one part, the spring, is imported from abroad. Once the parts are ready, they are placed in the inventory or assembled to create a new wind pump. When a community calls to report an issue with a pump, VEV goes onsite to assess the problem. If repairs are necessary, VEV does the repairs immediately if the parts are in stock, otherwise, the parts are ordered and the job is done when the parts arrive.
