APPENDIX - F: CONNECT IRWIN WELLS – BID OPTION 4 AND 5

1. PROJECT DESCRIPTION

1.1. PROJECT SCOPE

This scope includes design and installation of two main components:

Part A – BID OPTION 4 – Connection of existing Well I-9 (Facility 856) to the Langford Lake raw water line. Well I-9 is an existing well constructed in 1988 for use as a water point for dust control with a well pumping rate of 600 gpm. The well is permitted as an industrial supply well. The well has been off-line for some time and will require re-conditioning. For bidding purposes only, the new well pump is anticipated to be 125 HP submersible pump. Contractor is required to: permit the well as community water supply well; conduct a Water Well Condition Assessment, including television survey of the well with closed circuit television (CCTV); recondition the well to allow full production capacity, including chemical treatment and scale removal; install a new well pump; and design and construct a new well pump house, design and install a sodium hypochlorite generation system with storage tank, discharge piping, flow meter, control system, SCADA, and all required valves and appurtenances for a compliant production well. Well shall have airline and gauges installed for monitoring well levels (static, pumping and drawdown). Demolition and salvage is required of existing water point structure and piping, the submersible pump if the pump is found to be unserviceable, the adjacent light structure and control panel, and required utilities and appurtenances for construction of well house. Generator with secondary containment, control system, SCADA, and FE-8 security fencing is also required for the well. The building facade must follow the Master Planning Building Design Guide for Ft. Irwin and requirements listed in this specification. Although this will supply raw water to the new untreated water storage tank at the WTP of Appendix A, chlorine is required for this I- 9 well. System shall be automated to provide from 0.1 mg/l Cl2 to 4 mg/l Cl2 at the range of flows capable by well pump. System shall be connected to existing alarm system and telemetry system for monitoring and in full compliance with federal, state, and local requirements. Contractor shall determine range of pressures to overcome at connection point in the Langford Lake raw water line and design pump capable of maximizing flow rate at given pressure range. For bidding purposes only, the Contractor shall consider the hydraulic grade line (HGL) for the Well I‐2A at the connection point shown in the RFP drawings (through hydraulic modeling) to range from 2,700 to 2,752 ft (depending on the number of booster pumps operating at Langford Lake Booster station). Well pump shall be premium efficiency pump/motor and shall operate within the optimum range of the pump curve (shall not exceed pump curve limits). The Contractor shall test the water quality of Well I-9 for use in design of Water Treatment Plant. The pumproom floor shall be provided with a floor drain discharging to a sump at least twenty-five feet from the well. A valved pump test connection shall be provided downstream of check valve designed for discharge away from pump house to nearby storm drainage system with proper erosion control methods.

Part B – BID OPTION 5 - Well I-2A (Bldg 43) is an existing well with pumping rate of 400 gpm. The well was previously permitted as a public water supply well, but has been out of service since about 2003 due to high nitrates. The well is not currently permitted as a public water supply well. The well is

APPENDIX F - Page 2 of 22 Amendment No. 0007 plumbed into the RO system and to the DO system. The scope of this effort includes permitting the well as an industrial supply well; disconnection of the well from both the RO & DO system (after the construction and acceptance of the new water treatment and distribution system); conducting a Water Well Condition Assessment that will include removal and a condition assessment of the existing vertical turbine pump and bowls; conducting and recording a downhole video survey of the existing well with Closed Circuit Television (CCTV); reconditioning the well to allow full production capacity, including chemical treatment and scale removal; and design and constructing a new well pump, design discharge piping, flow meter, control system, SCADA, and all required valves and appurtenances for a compliant production well. Well shall have airline and gauges installed for monitoring well levels (static, pumping and drawdown). Refurbishing existing well pump house shall include repainting the existing building walls and roof system. The well will discharge to a new adjacent water storage tank (assumed to be 2,500 gallon, for bidding purposes only) via an air gap. A new booster station building shall be designed and constructed along with new variable frequency drive (VFD) high efficiency pumps, valves, flowmeter, SCADA, control system, and all required valves, utilities, and appurtenances to draw supply from the water storage tank and discharge to the to the nearby reclaimed water (REC) purple pipe system. A sodium hypochlorite chlorination system shall be designed and constructed as part of this Bid Option. System shall be automated to provide from 0.1 mg/l Cl2 to 4 mg/lCl2 at the range of flows capable by well pump. System shall be connected to existing alarm system and telemetry system for monitoring and in full compliance with federal, state, and local requirements. The centrifugal pumps shall be sized to provide the maximum well yield and ramp down as required to match pump output to system demand (paced on system pressure). The REC irrigation system currently delivers up to 600 gpm, with current usage of 550 gpm during the summer and 350 gpm during the winter. This well is intended to be used to provide or supplement irrigation water (in the event that the wastewater treatment plant does not meet permit or quantity requirements) or for testing the water system during daylight hours. It is assumed, for bidding purposes only, that the well pump shall be a 75 HP vertical turbine well and two booster pumps shall be 25 HP centrifugal pumps. Hydraulic modeling was conducted for the REC water system to determine the HGL range for the tie-in point for I-2A.

Depending upon the location and intensity of the irrigation demand during the irrigation cycle, the required HGL for the Well I‐2A booster to pump to in the recycled water distribution system was determined to range from 2,671 to 2,730 ft. Contractor shall complete the design for the well pump and booster pump based on actual field conditions. Booster pumps shall be premium efficiency pump/motor and shall operate within the optimum range of the pump curve (shall not exceed pump curve limits). Drainage shall be provided from pump room to discharging to a sump at least twenty-five feet from the well.
