Just as different water utilities use different processes for turning raw source water into potable drinking water, so too do they take different routes to account for, and bill for, their output. Here is an overview of a cellular-based approach to collecting and leveraging data from water distribution operations that can achieve the greatest business advantage.
It’s that time of year again; reviewing contracts and sweating over the fact of having to notify clients about pricing changes. Why do we get so concerned? Other industries have no issues with raising prices — think of the increases we have come to know on a yearly basis including electric, cable, water, and property taxes to name just a few. However, our increases usually come with improvement of our services yet we still worry about customer’s reactions. Luckily, I have some good news: It’s time to stop worrying because there are more benefits than downsides of warning our clients about price increases.
