This is something business first learned a long time ago. In the 19th century, when organized labor first compelled factory owners to limit workdays to 10 (and then eight) hours, management was surprised to discover that output actually increased – and that expensive mistakes and accidents decreased. This is an experiment that Harvard Business School’s Leslie Perlow and Jessica Porter repeated over a century later with knowledge workers. It still held true. Predictable, required time off (like nights and weekends) actually made teams of consultants more productive .
Water experts know, however, nitrate levels in Iowa’s waterways regularly exceed the public health threshold. Despite building the world’s largest Nitrate Removal Facility in 1992, adding off-river storage, treatment ponds and two additional water treatment plants, the costs and difficulty to remove nitrate from source water continue to escalate. Rising nitrate concentrations in the Raccoon and Des Moines Rivers now require Des Moines Water Works to plan for several nitrate management projects in order to comply with the drinking water standard. The first project is the design then construction of an expanded Nitrate Removal Facility that will double treatment capacity from 10 million gallons per day (mgd) to 20 mgd.
