v ACWA Outreach Alert - Opposition of SB 845 (Water Tax)
v Questions Posed at Previous Commission Meeting:
Ø A Commissioner asked about sign poles posted in the City without signs.
§ Poles without signs were removed by Public Works Maintenance Division staff. The Public Works Superintendent requests that if any poles without signs are seen, to please report to Public Works at (909) 820-2602.
Ø The SCE PSPS Circuit Map was requested from SCE.
§ The maps for the Rialto area are attached.
Ø A Commissioner asked about the length of time it takes for composite poles to burn in comparison to wood poles.
§ The following is SCE’s emailed response received on September 20, 2018:
“Short answer is that if the fire is hot enough and slow moving enough Composite Poles will burn and fail just like wood poles, however that generally isn’t the case. Typically fires burn between 1,200°F - 1,800°F and advance over a static location within 60-90 seconds, this is where the value of composite poles lies. They are tested at 1,800°F for a duration of 3 minutes after which they self-extinguish and maintain 100% of their design breaking strength. Wood poles on the other hand continue to smolder after the direct flames are removed and that smoldering continues to weaken the pole until it fails.
Composite poles make it more likely that SCE’s lines will stay in the air and make service restoration after the fire more expeditious.”
Ø Containers of Sand Left on City Streets (SCE Poles Replacement)
§ This question about large containers of sand was directed to SCE at the September Commission meeting.
On October 4, 2018, the SCE reported the bags were cleared off the street and the project was postponed until next year.
Ø A Commissioner asked about power usage at the Ayala Pump Station and the monthly variation in kilowatt hours.
§ Electric usage at Ayala during 2018 is as follows:
While the past two months had a significant variance, the normal power usage as shown in prior months was more typically higher. The decrease in power usage over the past two months was caused by a partial failure of the aging pumping control system which prevented pumps from operating properly (an emergency overflow pipe avoids station flooding). This control issue resulted in the decrease in power usage the Commissioner observed.
Attempts at repairing the controls proved unsuccessful. Veolia has a replacement control system on order which will be installed as soon as it is received. This will resolve the operational issue. Once the controls are replaced I'd anticipate that the monthly Ayala power usage will be approximately 9,000 kilowatts per month.
