Drinking water companies with ageing networks are facing vast amounts of drinking water network reconstructions during the coming decades. This development coincides with the energy transition, which puts pressure on the available space underground. These external drivers give drinking water companies an opportunity for rethinking their networks and design principles. High velocity self-cleaning networks are substantially cheaper, more reliable and deliver drinking water of better quality to end-users compared to conventional networks. High velocity self-cleaning networks actually need to be designed considering instantaneous downstream demand. It needs practical tools embedding design rules, which supports network design in daily practice. Recently such a comprehensive design tool for drinking water networks was developed by The PeopleGroup based on over twenty years’ experience of KWR in designing these advanced networks with a basic spreadsheet [1]. This tool was incorporated in an integral design tool encapsulating the whole design process. The tool accelerates the design process of tailor made high velocity self-cleaning networks with a factor 5-8 including work preparatory work. The tool allows for embedding possible future restraints in network design, such as unwanted heating of drinking water due to underground anthropogenic heat sources [2].

In PPXX, a technology was presented for the first time that could bi-axially orient polyolefin pipes. With this technology, it is possible to prepare pipes that have a performance far beyond the standard ones. One approach to achieving this performance is via a continuous in-line process. To optimize the in-line...

The use of corrugated HDPE and PP pipe for gravity flow storm sewers is a growing trend throughout the United States. Many of these drainage pipes are buried in shallow cover conditions under roads with heavy traffic. It is well established that thermoplastic pipe installations under shallow cover respond differently...

The required wall thickness for a fully fused HDPE water main subject to an earthquake induced lateral spread is addressed in this paper. The water main is assumed to be buried via cut and cover (i.e., open cut with typical burial depths in the 2 to 15 feet range) procedures and any laterals have small diameters. For...

A practical requirement of temperature resistance of minimum 50 years at 70°C was established for the extra high voltage (EHV) corridor projects in Germany. Experts have debated what tests are best suited to prove the suitability of a pipe resin for cable protection pipes which may be installed hastily and under...

A significant amount of water is lost in transit from the water treatment plant to the consumer. A major cause of water leakages is the deterioration of assets including the use of disinfectants. Using chlorine-based disinfectants is known to be extremely effective in eliminating waterborne pathogens, but they also...

Microplastics in drinking water and in food in general has been a topic with ever increasing interest since a publication of a study in the British newspaper The Guardian. The microplastics topic has also high focus on governmental level, e.g. in Germany where a report of Fraunhofer Umsicht /1/ estimates the amount...

All thermoplastic and thermoset pipes must consider the impacts of cyclic loading on overall performance. Since its first use, PVC pipes have been tested for its resilience to such loading. As testing evolved over time, the method to determine cyclic capacity for gasketed PVC pipes has improved. Previously, the...

Structural behavior of flexible plastic manholes is very different from rigid concrete products. Although this is state-of-the-art knowledge, no international or EN standard exists on structural design of these products. Therefore, traditional soil models and soil pressure coefficients are usually applied if...

Spigot bevels (also referred to as chamfers) for plastic pipe joints using elastomeric seals are well-known and often prescribed in standards such as ISO 1452 for PVC-U and 16422 for PVC-O. The most common type of bevel is a simple straight cut at a 15° angle with respect to the pipe axis, leaving approximately 50%...

The Plastic Retainer Ring (PRR) gasket is an old friend of pipe joints, and it is still used among other sealing solutions developed more recently. With origins traced back to the end of the 1960s, it is recognized among the first solutions developed for gasketed plastic pipe joints. It is very likely to have...
