Notes should be made regarding meter condition or special situations. Additional meter readings may be required depending on water supply conditions and water user requests. An example of such a form is Fig. E-3 of Appendix E. All meters should be routinely removed, inspected, and serviced. Where relatively clear water, free of debris, is delivered, water meters may need to be serviced less frequently than where turbid water or water carrying debris is metered. Continued variation in meter calibrations is an indication that the meter needs servicing.
Daily visual inspections of all system facilities should be maintained noting malfunctioning gates or meters, seepage areas, cracks in concrete lining, sloughing of banks, and other irregularities. Upstream and downstream check elevations should also be recorded at each check site where applicable. Pressures and flows should be noted at all critical locations in pipeline systems. All incorrect system conditions, improper water usage, and inappropriate daily activities taking place in each area of responsibility should be reported immediately.
F-3 of Appendix F). Safety presentations and ongoing discussions on safety problems within the organization need to be recorded, and any recommendations made need to be noted. The safety program should be ongoing, with various materials, such as posters and fliers, being posted and distributed continuously to emphasize to all employees the importance of safety. Unsafe Conditions Any unsafe condition should be reported by the first employee noticing such a condition. A sample form for this purpose is provided as Fig.
