12 K. Non-Rate and Extraterritorial Customer Accounts Receivable Aging
The total accounts receivable for non- rate and extraterritorial customers is $ 244,000. Of which $224,000 is current and $19,000 is past due. The largest balance is City of Fontana at $131,000 and is fully current. Additionally, Cedar House carries a $13,000 balance including the $6,800 past due. Cedar House has been contacted for the past due balance. Vertical Bridge holds a $10,000 balance consisting of the past due amount of $7,500 of unreconciled delinquencies. Sprint-Nextel has a small net balance due to prior unreconciled delinquencies as well.
To improve collections performance, targeted follow -up should continue on the accounts with overdue balances and reconcile disputed balances. By way of maintaining regular communication with customers carrying amounts over 90 days, older receivables can be reduced and overall aging trends can improve.

No violations were received during this reporting period.
C. Source Water Total Dissolved Solids (TDS)
Veolia has a goal of maintaining an acceptable blended TDS level between all its sources. This goal is achieved by shifting production to or from the lowest TDS wells or purchasing low TDS water while adhering to the overall water supply strategy and meeting system demands. The TDS was on average 259 mg/L for the month of April as compared to 268 mg/L in May. The TDS levels are below the secondary maximum contaminant level requirements.

VI. WATER QUALITY COMPLAINTS
No complaints were received during this reporting period.
14 VII. OPERATIONS UPDATE
The overall operational strategy is to meet the daily water demand. The City of Rialto water system has six operational wells, one of which is owned by the County of San Bernardino and operated by Veolia; Oliver P. Roemer Treatment Plant (OPRTP), which is jointly owned by the City (25%) and West Valley Water District (WVWD); purchased water through the Baseline Feeder (BLF) system from San Bernardino Valley Municipal Water District (SBVMWD); and, if required to meet demand, additional water can be supplied by the City of San Bernardino (CSB) through the BLF for emergency supply only with no guarantee of actual delivery. Water produced from City Well 4A discharges into the BLF and its production is included in deliveries from that shared transmission line when City Well 4A is in service.
The overall pumping strategy is based on adjudicated rights, well availability, remediation requirements, and quality of source, cost to operate, and varying weather conditions. TDS effluent concentrations for the City of Rialto WWTP are taken into consideration when operating the facilities and water sources.
A. Operational Wells
City well #2 will be out of service for 4 weeks to replace the upper pump column bearing; will return into service by March 2026. City well #2 returned to service on March 10th
Valve Activity
On the basis of information collected in 2019, Veolia now has a baseline assessment of all valves and has initiated a new cycle of valve exercising. Five valves were exercised in the month of March.

5/1/2026 340 E Orchard Customer service reported a resident's recurring overwhelming sewer smell at 340 E Orchard. The
technician investigated, found no current smell or
manhole issues, and will schedule a courtesy clean.
ET
5/4/2026 855 W Valley Customer service reported a possible sewer backup at 855 W Valley after speaking with the resident. The
technician determined it was private property, advised a plumber, and placed containment socks near the storm
drain.

5/5/2026 1173 CACTUS #2 Customer service received a call from City Public Works regarding a resident at 1173 S Cactus #02 who reported
roaches coming from a nearby manhole and requested
that wastewater spray the area. The technician stated
that they have addressed this same problem for the
resident before. Golden Bell recently sprayed the area, and they personally placed poison below the manhole
ring, then corked the lid. Despite these efforts, Britt noted the resident is still not satisfied. A courtesy clean was done of the sewer line and manhole.
