STC25 — The drainage industry standard

CDR's STC25 Computerised Sewer Records System is based on the DoE Standing Technical Committee Report no. 25 which defines a standard method of storing sewerage data. The STC25 system stores manhole card data in digital format, allowing the data to be manipulated, exported and reported quickly and easily. An integrated data validation routine checks network consistency and ensures data accuracy is maintained.
