Utilities - Water Treatment

As part of the ongoing waste water treatment and clean water treatment infrastructure improvement programme, 4 Square has been involved for over two years in the inspection and DSEAR verification of treatment works throughout the UK.

We have carried out inspection and verification activities in waste water and clean water treatment systems including those associated with ammoniation and chlorination systems.

Site activities include formal analysis of the key safety documentation (e.g. safety management systems, area classification, etc.) and inspection of installed equipment.

We also provide specific safety documentation for our clients including Explosion Protection Documents (EPDs), Zoning System Documents (ZSDs), Intrinsic safety system specification and certification documentation.
