RECORDS AND REPORTS

Water Treatment Reports

A record system has to be developed which should be realistic and applicable to the operating problems involved in the Transmission system. Management must be clear as to why the data/ information are collected, as to who will review the data and who will respond to the results of review. The most efficient way to keep records is to plan what data is essential and then prepare the formats followed by guidelines, fill the data, frequency and to send the record to for review and report.

Sample records to be maintained are given below for guidance:

1. Updated transmission system map with alignment plan and longitudinal section of the pipeline showing the invert   levels and hydraulic grade lines of the pipelines and location of appurtenances, flow meters and pressure gauges,
2. Record of flow meter readings at upstream and downstream ends of the transmission system,
3. Record of water levels of the reservoirs at both upstream and downstream ends of the transmission system,
4. Pressure readings of the transmission system pipelines,
5. Review of record of pressures and flows,
6. Identify the persistent low pressures in the transmission system,
7. Record on age of pipes/quality of pipes,
8. Identify pipelines to be replaced,
9. Presence of corrosive water in the system,
10. Identify the source of leaks,
11. Identify the persistent leak points,
12. Status of bulk meters – functional,
13. Identify the residual chlorine levels at the receiving and transmitting ends of the transmission system,
14. Identify the bacteriological quality of the water sampled from the reservoirs linked to the transmission system,
15. Identify reasons for residual chlorine being absent/ where bacteriological samples are unwholesome,
16. Record on when the pipeline leaks were repaired or pipes changed and the cost of materials and labour cost thereof,
17. Record on when the gland ropes of the valves distribution system were changed and the cost of materials and labour   cost thereof,
18. Record on when the spares of the valves were changed and the cost of materials and
19. labour cost thereof,
20. Record on when the expansion joints were serviced and the cost of materials and labour spent for repairing the same,
21. Record on when the manholes on the valve chambers were changed and the cost of materials and labour cost thereof,
22. Record on man-hours spent on routine operations in the transmission system in the previous year and the cost thereof,
23.  Record on total cost of repairs and replacements in previous year along with break up of material cost and labour   cost with amount spent on outside agencies for repairs and replacements,
24. Record on when the exposed piping was last painted and the cost of materials and labour cost thereof.
25.  With the accumulation of all essential data a report can be prepared evaluating the O&M of the facility. The report   can identify the deficiencies in the system and its appurtenances and then plan future repairs to the transmission   system, valves and other equipment or for replacement of defective valves or other equipment.
