Peak day production was 1.61 MGD on October 21st. 5.1 inches of rainfall were recorded at the water treatment plant site during the month with 1.54 inches on October 9th. The smart meter replacement project wrapped up in October and will be completed once backordered meters arrive. The October billing was the first using the AMR system and a few manual reads performed by City staff to collect all meter readings.

WASTEWATER – A total of 24,060,000 gallons of sewage were treated and re-used for irrigation. Maximum flow was 1.74 MGD on the 12th. Rainfall totaled 1.0 inches on October 11th. Monthly rainfall recorded at the plant was 3.15 inches with a peak of one inch on the 11th. 647,040 gallons of sludge were dewatered and stored for future landfilling. We had one exceedance of the total coliform limit on the effluent that was conveyed to the land application site for irrigation. The work on the effluent filters was completed but filter No. 1 lost a seal that will be replaced in November. Veolia staff prepared and tested the UV disinfection system for use during the winter discharge season. Several major components of the influent screening system were replaced or rebuilt in October. Transducers on four of the five collection system flow meters were replaced under the manufacturer’s warranty and they are more reliably and consistently reporting level and velocity data.

STREETS – The contractor resumed work on the LED streetlight conversion project in October. We applied liquid de-icer during the cold snap during the last week of October.

PARKS, BUILDINGS AND GROUNDS – Repair and restoration work was completed on the rental house at Bornstedt Park in preparation for renting it in November. About 1:00 PM on October 30th a neighbor observed a break-in at the house. A window was broken and a door jamb was damaged in an attempt to gain access. Sandy PD responded quickly and made contact with several juveniles in Bornstedt Park and identified a suspect. The property manager made arrangements for the repairs.
