Condition forecast for individual mains

The risk of pipe failure is one of the factors taken into account by drinking water utilities when they decide whether or not to replace water mains. They assess this risk on…

Data mining for asset management – survey and water sector examples

Data mining (the search for statistical connections in databases) is one step in ‘Knowledge Discovery in Databases (KDD)’. Both have already been embraced by the marketing, medical care,…

Perspective and preconditions for the development and use of autonomous inspection robots in water mains

Asset management of distribution networks is currently based on generic knowledge and models of mains groups, supplemented by inspection data on a limited number of mains. Effective asset…

From mains data to mains knowledge

Decision-making about which mains to replace, and when, is one of the most important issues for asset management regarding the distribution network. With decision-support software, water companies can select which mains to…

Knowledge-based rules for PVC mains

As a result of the large-scale use of PVC by the Dutch drinking water sector since the 1950s, 52% of the current drinking water distribution network is made of this pipe material.…

Smart Wellfield: gains from smart management or separate abstraction?

In several Vitens’ wellfields, water quality varies greatly from well to well. This has adverse consequences for the treatment of the abstracted water. Over the past few years,…

Modelling regrowth in the distribution network

Regrowth in the distribution network is a complex phenomenon. Measures to manage regrowth in the distribution network have hitherto been based on a trial-and-error approach. We need a model-based description of the…

Circular water provision in horticulture: Water to the greenhouse – Freshwater provision and well technology

Water supply is of crucial importance for greenhouse horticulture. An adequate supply of fresh (irrigation) water has to be available – during dry periods as well – and…

From big water data to smart water grids

Due to far-reaching computerisation, smart metering, the use of (online) sensor systems in drinking water production companies and distribution networks, and automation, the quantity of ‘water’ data will grow inexorably into the…

Soil mechanics & dynamics

Information about the soil is available from a number of sources. This information is important in the estimation of the aging subsurface infrastructure. Waternet needs to structure these information sources and combine them with existing information systems…
