Water Demand and Wastewater Forecasting

Steve Simpson from Black & Veatch provides an update on municipal water demand and wastewater return forecasting. The forecasts support regional water planning, identifying future capacity needs and developing inputs for future scenarios. The process involved stakeholders from regional water councils and used updated data sources, including population projections and water utility reports. The video details the methodology for forecasting water demand and wastewater flow, including adjustments for outliers and specific needs. Results show projected increases in water demand and wastewater flow, with tools available for further analysis.

What was the main purpose of updating the water demand and wastewater flow forecasts?
