In the Netherlands, it’s important to have awareness if Sewer renovation (Rioolrenovatie) needs to be carried out to repair the sanitary sewer system supporting a residence. Although the idea presents major disruptions and costly excavation it’s no longer the case among Dutch sewer engineers and technicians. These professionals are now using modern technology in repairing sewers with very little digging work and at minimal costs.
Relining: The Modern Method of Rioolrenovatie in The Netherlands
Dutch sewer engineers and sewer technicians call this modern method of repairing or renovating damaged sewer systems as Relining. The technology is known in the UK and other European countries as Cured-In Place Pipe (CIPP).
The process involves the introduction by air of a flexible fibreglass or sleeve of felt into the sewer. The felt or fibreglass compositions are soaked in curing resin that will have a thermocuring interaction with an ultraviolet (UV) heat initiator.
The heat initiator of this CIPP renovation technology aims to provide circular heat inside the hose or pipe, which will warm the resin to efficiently repair or renovate the damaged pipe to ensure water safety.
A Brief Review of The Netherland’s Sanitation and Sewer History
As a backgrounder, the country has had a long history of faulty sanitation and poor management of wastes, using pail closets, outhouses and cesspits. It was only in the 19th century when the Dutch government followed suit to London’s implementation of a systematic and functioning underground sewer network.
However, it took years of discussions and debates before the Dutch government decided that the waste water being channelled out of houses and buildings must receive treatment before waste matters were released and discharged into the river.
However, the treatment process produced sludge, which was then transported and discharged into the sea by way of special vessels. In the years that went by, some of the underground sewage pipes got damaged through natural wear and tear.
The condition resulted in issues of water contamination especially when about 60% of the drinking water in Dutch households are taken from groundwater. In the Eastern part of the country, 40% of Dutch residents get their drinking water from surface sources.
This brief review of The Netherland’s sewage history demystifies the reason why drinking water flowing into households can be contaminated by different disease-causing microorganisms such as the following:Escherichia coli or E. coli, Listeria Listeria, Cryptosporidiosis, Campylobacter, Salmonella, Adenovirus, Norovirus
That is why even as we make it a point to wash fresh fruits and vegetables before eating them, we can’t always be sure the water we’re using is not contaminated.
