To prevent polluted water from entering the water system, including pollution caused by accidents and incidents at Amrita University, the following processes can be implemented:

1. Equipment Labelling and Identification

– Ensure that all underground services have marking tape placed at correct distances above pipework, complying with relevant standards.

– Use adhesive pipe markers on above-ground pipe works to indicate pipe contents or system type, along with directional arrows indicating flow. Install markers at a minimum of every five meters.

2. Asset Labelling and Bar Coding

– Provide equipment with asset labels and bar codes according to the university’s Asset Identification and Labelling Standard.

3. Below Ground Pipework

– Fully survey and document all pipework and services installed below ground in accordance with the requirements for Quality Level–Classification of Subsurface Utility Information (SUI).

– Submit and obtain approval for the CIS Standard – Permit to Dig Form from the department before installing or repairing any pipework located below ground.

– Provide CCTV recordings of below-ground sewer, stormwater, and sub-soil drainage pipework and structures before practical completion.

4. Above Ground Pipework

– Ensure that all pipework chased into masonry walls does not cross any movement joint and is provided with sufficient insulation to accommodate expansion and contraction without causing damage.

– Label all above-ground pipe works with adhesive pipe markers indicating pipe contents or system type and directional arrows indicating flow. Install markers at a minimum of every five meters.

5. Pipe Supports and Fastening

– Install pipework supports according to the spacing requirements for brackets, clips, and hangers.

– Provide separate supports for valves within pipework of 200mm or greater.

6. Core Holes and Sleeves

– Obtain approval from a structural engineer before coring any holes in floors, walls, beams, or columns.

– Provide copper sleeves or tubing for pipework passing through core holes or masonry/concrete walls or floors, ensuring a 25mm gap around the pipe.

– Install fire-rated pipe penetrations to comply with statutory requirements.

7. Corrosion Protection and Finishes

– Paint all surfaces exposed or susceptible to corrosion, including external surfaces of machinery, equipment, fittings, tanks, and services.

– Use hot-dip galvanizing with a minimum coating thickness of 0.1mm for ferrous metal exposed to the atmosphere or in humid conditions.

8. Acoustic Performance of Hydraulic Pipework

– Ensure that all hydraulic services comply with the acoustic requirements of the National Construction Code (NCC) through treatment of building elements and system pipework. Obtain assessment and certification from a qualified Acoustic Engineer.
