D. 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 purchased low TDS water while adhering to the overall water supply strategy and meetin g system demands. The TDS was 233 mg/L for the month of April as compared to 233 mg/L in March. The TDS levels are below the secondary maximum contaminant level requirements.

VI. WATER QUALITY COMPLAINTS
No complaints were received during this reporting period.
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 Count y 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 Munici pal 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, c ost 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
All wells were operational.
B. 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 . 60 valves were exercised for the month of April.

4/16/2024 1004 S Riverside
Ave
Unit 2's cleanout was overflowing. The spill
ran down the complex to the storm station
on the property. The storm station pumps
were tripped, so no sewer reached the city
right of way. I notified Tim Sun of Rialto Code
Enforcement, the Supervisor, and the
property owner. I was informed that a
plumber was on the way and would open the
line and clean the sewer spill. The call ended.
ET
4/17/2024 827 W Tullock I received a call from customer service stating that the residents at 813 and 827 said
that manholes on the street were
overflowing. When I arrived at 10:58, I
discovered this area was new construction,
and we did not have maps. We figured out
the direction in which the flow went out. We
were able to clear the blockage at 11:50 AM.
The blockage was caused by contractors
leaving debris in the downstream manhole.
PH, ET,
BVO, ZG
4/19/2024 324 N Plam Ave A manhole overflows on the property down an alleyway. The blockage was caused by
excessive grease in the line from upstream
restaurants. The blockage was cleared, and
the area was washed down and vacuumed
up.
PH, BVO
4/25/2024 258 W Shamrock A resident reported a sewer line blockage. I called the admin at the wastewater plant to
translate it into Spanish for the resident. I
informed the resident that the sewer line
was clear, the blockage was in the lateral,
and they would need to call a plumber to
resolve the issue.
BVO
4/27/2024 813 Tullock The HOA plumber called to report an overflowing manhole. Upon inspection,
several manholes were slightly surcharged.
Blockage was downstream on Idylwild again.
Once the blockage was cleared, the flow was
restored. The pipe in the manhole is
scheduled for repair due to contractor error
during the tie-in.
BVO
4/29/2024 1302 N Riverside A call for a slow-running sewer. The line running in front of the church was clear.
Upon further investigation, the problem was
determined to be lateral needed cleaning.
BVO
6 4/30/2024 750 E Rialto #8 False alarm, not a sewer problem but a broken water line.
