According to UFB-30-Q-65503_rev.01E The Follo Line project, EPC TBM. FMECA report for the Drainage System ¿[R4]:
- Section 5.3. Overview of preventive maintenance activities with 
optimized intervals.

Kommentar:
Maintenance shall be performed according to list of less critical and more critical areas. A preliminary list of less critical and more critical areas can be found in the FMECA report. Maintenance routine and interval cannot be finalized until the results from the flushing process and testing of tablets for the drainage system are ready.

As the drainage system is different than other drainage systems used in railway tunnels today, generic routines cannot be used. Therefore, experience from testing of tablets and flushing is critical.
