3. We need the actual GPM and Pressure from the 10” Pump that will be supplying the 10” water supply line now that the 3rd RFQ changed the supply.

Response:

Please refer to Exhibit A for the attached Pump Check - Hydraulic Test Reports for the San Bernardino CSA 70 Glen Helen Water System. The reports are dated June 26, 2026, and pertain to Wells #1A, #3, #4, # 5, and #6. Additionally, there are reports dated July 11, 2025, for Well #3 and Well #5, for reference.

a. Will the hot-tapped 6” line produce, with all the fittings, the 800 GPM needed at the Dip Tank?

Response:

Yes, the hot-tapped 6” line must produce, with all the fittings, the 800 GPM needed at the Dip Tank.

b. Determine what sized line will be needed at the Dip Site to accommodate the 700’ line loss plus 6.5’ lift at the Tank's air gap.

Response:

The awarded contractor for this project shall be responsible for determining the appropriate pipeline size for the Dip Site, utilizing the Hydraulic Test Reports included in this addendum.

This determination must account for a 700-foot line loss, a 6.5-foot lift at the Tank's air gap, and any unforeseen requirement in the project site.

c. Once that is determined, what PSI and GPM are determined at the Dip Tank, we will need to discuss what SCADA Valve.

Response:

The contractor is responsible for determining the PSI and GPM at the Dip Tank after selecting the appropriate pipeline size for the dip site, in accordance with the guidance for item b.

Please refer to Exhibit A for the attached Pump Check - Hydraulic Test Reports for the San Bernardino CSA 70 Glen Helen Water System, dated June 26, 2026, for Wells #1A, #3, #4, #5, and #6. For reference, there are also reports from July 11, 2025, for Wells #3 and #5.

5. Is this pump for irrigation or tank refill?

Response:

These pumps are designed for domestic water use and can supply multiple tank reservoirs.

6. Is the Pump control – On/Off/Variable?

Response:

This pump control utilizes either a manual or a level-type mechanism, which will be verified in the field.

7. Will there be a valve to divert water to the Helicopter site to control pressure and volume?

Response:

There is currently no valve available to divert water to the helicopter site; therefore, it is advisable to utilize a hot tap for this purpose.

8. Does the county have any restrictions on Hot Taps 10 x 10?

Response:

The proposed size-on-size hot tap has not been approved. AWWA C223 establishes minimum requirements for tapping sleeves but does not constitute approval of a size-on-size application.

Considering the extent of the existing main that was removed, along with the associated structural and operational risks, the connection shall be completed using a properly restrained cut-in tee. The contractor awarded for this project must submit shop drawings to the Special Districts for review and approval prior to commencing any fabrication work.

9. Pure County SCADA without interfacing with proprietary remote activation. Co. has SCADA at Pump House, so no integration or encryption issues:

a. What NEMA Demarcation Panel would you recommend placing inside the cabinet to house the County SCADA components?

b. Should we use Fiber or CAT6C for the data backhaul into the cabinet? Then the County plans to connect four (4) Features already installed on HeloPod, which will require wiring into the cabinet.

Wildland Firefighting Helitanker Station Addendum No. 2 Page 4 of 5

c. What components will be required inside the panel to connect to the backhaul cable?

Then connected to control the four (4) Features.

d. Will the Panel need to operate on12 or 24 Volts? This will affect the number of 12V batteries & panels required.

e. How will you control the SCADA 6-inch and 8-inch external Cla Val Fill Valve located just before the Tank? Should this be done at the Pump House before the power conduit runs to the dip site?

Additionally, could you provide information on the following components?

• RTU / PLC

• DC-DC Converter

• DC-AC Inverter

• DC-to-PoE Injector

• (12V or 24V DC) (Stabilized DC) (48V-56V DC)

• Field Sensors

• Actuators / Relays

• Radio / Router

• IP Camera / Radio

Response:

These queries will be addressed following the contract award to the approved contractor and will be clarified during the project's construction phase.

A reduction in your energy usage and cost would occur, as shown below, if this pump was redesigned and/or rebuilt.

The following analysis and projection assumes that the water requirement, GPM, total pumping lift and hours of operation will remain as they were at the time of the pump test.
