Pre-functional test plan and functional performance test plan for water and sewage treatment systems

It is to be assumed that individual components and packaged equipment have been tested by the manufacturer. As part of the commissioning effort each component should be checked for damage, deterioration and failures by a procedure using inspections and tests as defined by the specific equipment manufacturers. Equipment manuals from manufacturers identify the minimum required receipt inspections, handling and installation procedures, drawing and wiring verification, field inspection and installation checks, verification of removal of shipping braces, inspection of installation against drawings and nameplates, inspection of components for damage and cleanliness, inspection of insulators and grounding, inspection of anchorage and alignment, adjustment checks, mechanical operation and interlock checks, lubrication application and verification that local safety equipment is in place.

1. Chemical selection verification. As part of the commissioning effort proper selection and dose quantity of chemicals for treatment of water and sewage need to be verified. A procedure must be followed to insure proper chemical treatment and water quality.
2. Safety, water and sewage treatment systems. Many tests on equipment involve the use of chemicals, combustible gases, high voltages, high currents, pressurized water and rotating or moving equipment. These conditions can be dangerous to personnel and damaging to equipment. A procedure must be followed to insure adequate safety rules are instituted and practiced to prevent explosion and/or injury to personnel performing the tests and other personnel who might be in the local area. Sanitary manholes contain harmful gases and are considered confined space. Confined space entry safety procedures must be followed, and adequate ventilation provided before entering a manhole.
3. Test equipment, water and sewage treatment systems. It is important that in any test program the proper equipment is used. The equipment should be calibrated, in good condition and used by qualified operators as required by a procedure. Any test equipment used for calibration shall have twice the accuracy of the equipment to be tested. All equipment should be operated in accordance with its instruction manual. A procedure defining installation inspection and a system test needs to be provided.
4. Inspection checklists for water and sewage treatment systems. Inspection checklists for the typical water and sewage treatment systems are presented in figure 9-5, Water supply and treatment system inspection checklist and figure 9- 6, Sewage treatment systems inspection checklist. These are filled out to serve examples of typical equipment conditions. For convenience, this checklist is included unpopulated at the end of the course material.
