Rob Lawson presented Artesia’s new A2D2 demand analysis tool at the Aquator User Group meeting in Oxford on 18 October. A2D2 (which stands for Aggregating and Allocating Demand Data) is a web-based app that uses water company demand data from district metered areas (DMAs) and assigns it to demand centres in the water resources model, Aquator. This innovative tool means that water companies can develop more accurate, real-world representations of customer demand and leakage in their strategic models. This in turn means that companies can develop a better picture of demand in their region, and ensure that their operational responses and investment plans better reflect reality.
The work Artesia has done with A2D2 for Welsh Water has shown its value in differentiating between different patterns and scales of demand in areas dominated by tourism, university towns and also the varying effect of weather on normal household demand from year to year.
