guidelines storm water managementFormulation of Dutch sewer guidelines
Until the end of the 1980’s sewer systems in the Netherlands were neglected as a public infrastructure that needed consistent asset management. Best management practices (BMP’s) were subject to discussion, while not being effectively exchanged between municipalities. This gave rise to a new national platform, Institute RIONED, to manage insights and to derive guidelines for sewer management. The project formulated the “Sewer Guidelines”, which through the years have become an understanding on their own, providing information of regulations, design, assessment of hydraulic performance, cost analysis, monitoring of new and existing collection systems of sewage and storm water.
urban water & drainage policymunicipal sewer plan the hague
The Dutch city of the Hague has an extensive sewer system that ensures healthy living in the city. The system that collects and removes sewage and rainwater encompasses about 1,400 kilometres of underground pipes and features 30,000 inspection shafts under the city’s streets. Some of the sewer pipes date from 1880 and are still working. The “Municipal Sewer Plan The Hague” was developed to monitor the system and replace infrastructure were required. The plan outlines the strategy dealing with various sewer and urban water problems and, most importantly, provides the (financial) justification and means to ensure the performance of the system.
policy for data, acquisition & utilizationStructuring the decision making in the data/information/knowledge chain
Clients are supported in their decision-making by structuring the process of data collection, information establishment and finally knowledge development. In the first stage, raw data is collected from measurements and inspections. The second stage is a process of activities, such as establishing and deleting wrong data, complementing missing data and processing data to a form in which they can be analysed, by which information is derived. The final stage is crucial for the quality and acceptance of an advice. Our philosophy is to carry out this analysis together with the manager of the infrastructure. We do not just give an advice, we help the manager to understand the behaviour of his infrastructure so that the final decision is not something that he is informed about through a report but is actually his own decision. What we try to establish, together with the client is to what level he needs to be supported.
