| Water Production Stands at 6.7 Million Cu.M |

“Despite the increase in hours of interruptions in pumping operations, and the decrease in average operating hours per well, total production inched up 0.01 percent.”

“NRW this January hit a six-year record low at 23.39 percent. It was way back in April 2003 when a lower NRW was recorded.”

Total water production stood at 6.7 million cubic meters this month, just about the same as last month’s production, but 2.24 percent higher compared to the total production recorded in January 2008.
Daily production averaged at 216,125.5 cubic meters, 16 cubic meters more than last month’s average daily production of 216,109.3 cubic meters.
The slight increase in production occurred despite the 100 percent increase in the duration of interruptions in pumping operations caused by

maintenance activities and power outages. The average operating time per well also decreased 2.55 percent from 662 hours in December 2008 to 646 this month.
Since January last year, water production took on a steady course as no significant peaks were recorded. Average daily production ranged from a minimum of 211,000 cubic meters in January 2008 to a maximum of 220,000 in November. The overall average for the 13-month period was 216,000 cubic meters per day. |

| Billed Consumption Beats Record High |
|
Billed consumption this month soared to 5,132,830 cubic meters from only 4,638,617 last month. This set another record in the history of the utility, and the second time that billed consumption stroke above 5 million cubic meters. The first time was recorded in October last year at 5,130,411 cubic meters.
Daily consumption during the month averaged at 165,575 cubic meters, up from last month’s only 149,633 cubic meters.
|
|
This translated to more than 50,000 cubic meters that went unbilled everyday during the month, considerably lower than last month’s unbilled consumption of over 66,000 cubic meters daily. Unbilled water consumption constitutes NRW and includes both authorized and unauthorized consumption.
Per capita consumption consequently rose to 211 liters per day, 14.83 percent higher than last month’s 184 liters.

| Lowest NRW in 6 Years Recorded |
|
Non-revenue water this month improved to 23.39 percent of total production due to the upsurge in billed consumption coupled with steady production volumes. This was the lowest NRW recorded in almost six years. A lower NRW was registered way back in April 2003 at 23 percent. Since then, NRW followed an increasing trend until it became under control again starting in 2007. With more intensified NRW reduction programs this year, hopes of attaining NRW below 25 percent levels at the end of the year are certainly within reach.
|
|
NRW usually drops in January after registering the year’s peak in December. This trend could, however, be attributed to different reading periods for production and consumption. A longer reading period for one month can be offset by a shorter period during the succeeding month, thereby showing an erratic NRW trend. A more realistic pattern can be better shown using a moving percentage method of NRW computation since this could hardly be affected by differences in reading periods, particularly for water consumption.
