The problem
Water customers need to be able to handle their own tasks
A water company's customers ask the same questions every month: how much is this period's bill, how the water price is worked out, how to pay, and how to report a meter reading. As a joint-stock company, Giwaco also has to publish reports and resolutions for shareholders, and regular water-quality results.
