Tanks:During the October period, we experienced 14 days where one or more of our storage tanks fell below the 75% fill level. The detail is as follows:
Tank #1 –Total of 1 day – Earthquake caused mainline failures (2).
Tank #2 –Total of 5 day – Operational Decision
Tank #3 –Total of 4 days – Operational Decisions
Tank #4 –Total of 8 day – Operational Decision
At no time during the month did any storage tank fall below 50% capacity.
(Covers time period of October 1st thru 31st 2011)
Production for October 2011was approximately 18.12MG as compared to approximately 19.71 for 2010, representing a decrease in production of approximately 1.59MG. A comparison of the weather between October 2010 and October 2011 (using a private weather station located in YLP) shows that the average temperature in 2011 was approximately 0.8° higher during 2011 than in 2010. Rainfall in 2011 was 1.94 inches while 2010 had much higher rainfall of 6.06 inches for the period. It should be noted that the local weather station in October 2011 is missing the data for the last 10 days of the month thereby skewing the comparison data. Water used for fire hydrant maintenance activities, flushing the system in response to customer service requests, after leak repairs and fire department training and/or suppression activities accounted for 57,220 gallons in 2011 compared to 229,255 gallons in 2010.
*Please note that the production numbers listed above do not include the discrepancy found to exist in the Well 40A at the MTBE treatment plant in both 2010 and 2011. I have adjusted the monthly production sheets to account for MTBE Plant production based only on the discharge from the plant to the system. This creates a more realistic comparison of the water produced.

Well Status:
Well 1A(YSP & Corral Dr. North end): This well is functioning properly with no concerns to report at this time. This well is operated during the month on an as needed basis.During October, this well was operated for 29 out of 31 days producing 2.887M gallons.
Well 1E (YSP & Cavestone Ct):This well has recently developed operational issues. The well will start and run for a period of time and then shut-down. The electrical components all appear to be fine and the motor does not appear to be drawing current outside of the normal spec. We are continuing to run test to determine the cause of the problem. This well is operated during the month on an as needed basis. During October, this well was operated for 5 out of 31 days producing 448,800 gallons.
Well 28B (YSP & clubhouse drive):There is no additional new information to report at this time.This well is operated during the month on an as needed basis. During October, this well was operated for 0 out of 31 days.

Well 35A (Ranger circle dr. @ Revis Rd):No new information to report at this time.This well is operated during the month on an as needed basis. During October, this well was operated for 0 out of 31 days.
Well 36A (Long Hollow Ct. North): This well is functioning properly and there are no concerns to report at this time. This well is operated during the month on an as needed basis. During October, this well was operated for 19 out of 31 days producing 1.687M gallons.
Well 37A, Well 40A(MTBE Treatment Plant): On October 3rd we suffered a complete hard-drive failure in the SCADA computer for the treatment plant. Our backups were also being written to the hard-drive as we do not have any external device for backup storage. We contact TESCO who built the system and they responded to assist us. Using parts from the old YLOA office computers, we were able to minimally restore the computer operations. Part of the problem that still exists is that the original software that controls the treatment plant was stolen along with our safe some years ago. I am looking into our options for replacement of this software. Additionally, we have lost the communications with our storage tanks as this part of the system was done by a different company and we are having difficulty retrieving the data necessary to restore communications without spends a considerable amount of funds. This past Wednesday I found the treatment plant with motors running but no production to the distribution system. It appears to me, at this point that the primary booster pump impellor may have failed causing the loss of system production. I have isolated this booster and switched operations to the secondary booster so the plant is still operational. I will complete my investigation and damage discovery next week and then schedule repairs as necessary. I do not believe that this potential failure has any relation to the computer failure earlier in the month. During October, Well 37A was operated for 29 out of 31 days. During October, Well 40Awas operated for 31 out of 31 days. The treatment plant produced water to the distribution system for 31 out of 31 days delivering 6.81M gallon.
Well 39A (Outlot D Fire Road off Revis Ln East):This well is functioning properly with no concerns to report. This well is operated during the month on an as needed basis. During October, this well was operated for 0 out of 31 days.
Well 42A (Outlot D Fire Road off Revis Ln East): No new information to report at this time. This well is operated during the month on an as needed basis.During October, this well was operated for 22 out of 31 days producing 2.56M gallons.
Well 44A(Outlot H Long Hollow Ct. North):This well is functioning properly with no concerns to report. This well is operated during the month on an as needed basis. This well is a very low producing well at only about 5 to 7 GPM. It cost more in power, chemicals, and labor to run this well than the amount we bill for service. Because of this, we typically do not operate Well 44A unless overall production necessitates. We maintain its status with the state because it provides us with water credit towards our system requirement. During October, this well was operated for 0 out of 31 days.
Well 45A(Outlot D, end of Blue Heron):This well is functioning properly with no concerns to report. This well is operated during the month on an as needed basis. During October, this well was operated for 25 out of 31 days producing 1.59M gallons.
Well 47A(YSP, North of Revis Rd):No new information to report at this time. This well is operated during the month on an as needed basis. During October, this well was operated for 10 out of 31 days producing 1.52M gallons.
Well 48A(North Dome Dr. near North Dome Ct.):No new information to report at this time.This well is operated during the month on an as needed basis. During October, this well was operated for 0 out of 31 days.
Well 49A (Parking lot at Golf Course):No new information to report at this time.This well is operated during the month on an as needed basis. During October, this well was operated for 6 out of 31 days producing 615,604 gallons.

In October, four main repairs were made. One of these repairs was minor in nature and the repair was made using a repair clamp. The three remaining main repairs all required the replacement of a section of pipe. These sectional replacement ranged from 2-1/2’ to 20-½’ in length.
Two of the main repairs are believed to have been caused by a 2.0 magnitude earthquake on October 26th (4:36:51am) that was centered 1.79 miles and 1.65 miles respectfully from the epicenter of the quake. The epicenter was located across the Fresno River (Rd 400) roughly north of YLP. We have in previous years experienced suspected damage caused by earthquakes. It does not take a very large earthquake to inflict damage on our water mains and services. Because in many areas our pipe materials are in direct contact with rock there is no sand to protect the pipe from movement caused by any source. Include the age of the materials, the previous stresses place on these pipes and, in some cases, the thin-wall material type used during original installation and a minor earthquake can inflict serious damage on our water mains and services.
There were thirteen service line repairs made during the October period. Six of the repairs were made by adding corp-stops on the mainline and replacing the entire service line to the meter. The remaining seven service leaks were off-road. These were repaired using repair connectors.
There are currently five known active leaks. Two are believed to be service line leaks. The remaining three are leaking 2” valves the control the discharge from blow-offs. We are addressing these on a daily basis.
We have not set any additional water meters since the last reporting period. As of November 11th, we have set 2 new water meters YTD.
Compliance Testing:The remaining routine Title 22 testing was completed as scheduled on October 19th. During the end of November or the beginning of December we will perform round two of nitrate/nitrite sampling on all permitted wells. These tests are conducted twice per year in the spring and late fall/early winter periods.
Main Replacement Areas for 2011:The job drawings for this project have been completed and are being reviewed prior to inclusion in the RFP package.
Hydrant Inspection / Maintenance Program:The hydrants inspections for October were completed on time. November hydrant inspections have been started. I do not anticipate problems with their on-time completion.
Inventory Control Program:No new information to report at this time.
Corrections Regarding Meters at the MTBE Plant:No new information to report at this time.
Administrative Work:No new information to report at this time.
Field Reported Safety Concerns:As part of our weekly safety meeting on Wednesday mornings all staff are asked if they have any safety concerns to report. No employee has reported any safety concerns since the last monthly status report.
Weather Station:The software to collect and relay data from the weather station has been installed and the initial setups performed. The station is currently operating and collecting data in a controlled test mode in the YSPUC Field Office. Temperature fluctuation is performed using the forced air system of the building. Humidity is altered by allowing outside air currents to pass through the building. Wind speed and direction are adjusted using a portable fan.
I am currently awaiting the arrival of a guy wire kit to help stabilize the weather station and protect it from higher winds. This kit is scheduled to arrive on Wednesday the 16th of November. Installation should occur shortly thereafter barring any unforeseen emergencies.
Leak Correlator:I have now completed additional testing on this unit and find that it appears to be performing as advertised. I have used it to locate staged “leaks” in a known area and found it to be very accurate at multiple flow rates down to minor flows of a few ounces per minute. I have also used this tool on a couple of existing leaks and found it to be accurate. However, we will still have to spend additional time learning how to read it language in order to more precisely determine the exact location of the leak. For now I have been able to collect the data, review and suspect the location and then compare the actuals to the recording to see how well I have interrupted the information. Like any new and highly advanced tool there is a learning curve on the road to proficiency.
It is my intention to send this original unit back to the manufacturer and request the delivery of a brand new replacement unit and the scheduling of our factory training.
Automatic Flushing Device:This unit will be installed during the winter period. I will likely make the installation near January 1st so that the recorded discharges from this device will all occur in the same reporting years. This will make some of my comparisons a bit easier to work with.
Discolored Water Remedy Options:There is no new information to report at this time.
