Sewage signaling card

The sewerage monitoring map indicates at neighborhood level (area boundaries according to Statistics Netherlands) what percentage of the sewer system is older than 50 years. The lifespan of sewers varies widely and can be up to 100 years. The average lifespan is about 50 years, but this is regularly not achieved due to subsidence, for example. The map has classified the life of the sewer. '0-30 years' indicates that there is no to very small chance that the sewer system will be replaced within 10 years. '30-50 years' shows where it is likely that the sewer will be replaced within 10 years. '>50 years' shows where the sewer probably needs to be replaced (based on lifespan). The length is determined in meters per class.
