1.0 INTRODUCTION

Red Rock Canyon National Conservation Area (RRCNCA) is located at 1000 Scenic Loop Drive, Las Vegas, Nevada 89161 (Exhibit 1).

RRCNCA hosts over 1.5 million visitors per year. Many of these visitors stop at the Visitor Center building to learn more about the NCA, shop at a gift store, hike local trails, or begin a tour.

The Visitor Center building (VC) and its parking lot are served by two restroom facilities; one is part of the building, and the other is a nearby stand-alone structure (Exhibit 2). These two facilities collectively have (2) janitor sinks, (6) standard sinks, (15) water closets, and (5) urinals all which account for the total flow discharged into a nearby centralized small wastewater system (CSWS) that processes the flow. The CSWS location is shown on Exhibit 2 and is located at – latitude: 36.13385° / longitude: -115.42685°.

System Components

The CSWS was built in 2012 and consists of following:

a) (2) 15,000 gal primary tanks;

b) (1) 10,000 gallon dosing tank;

c) (2) transfer pumps;

d) (6) dosing pumps; and

e) (6) chamber beds totaling 23,760 sq. ft.

In effect, the first primary tank acts as primary settling and the second primary performs both a secondary settling and flow equalization. The second primary tank contains (2) - ½ hp 50gpm pumps; the dosing tank contains (6) - ½ hp 50gpm pumps. Both primary tanks utilize effluent screens. The system design capacity is 10,000 per day. Current water meter readings suggest the absorption beds receive approximately 3,200 to 3,750 gallons per day.

The pumping systems uses both liquid floats and an Orenco TCOM timing control panel. Pump on/off operations are controlled by both the tank floats and pumping time presets within the control panel. Each dosing pump is dedicated to one of (6) chamber beds each composed of (6) chambers. System as-built plans are located in Appendix A.

Documentation shows the original pumps were submersible Orenco model PF500512-20 – a Franklin Electric pump (Appendix B).

All existing pumps are submersible Franklin Electric:

Model 2445059010 ½ hp; 60hz 5 amps at full load; 0.37 kw RPM 3450 SF Max Amp 6 Single Phase Code R SF 1.6 Continuous Duty E79319 2- Wire Submersible Motor

System Operations and Maintenance

Pump malfunctions have dramatically increased in recent years due to age and lack of routine maintenance. Recent troubleshooting in January 2023 showed (4) of the (6) pumps to be inoperative and

(2) found to be drawing 5 amps.

Recent repair work includes the installation of new dosing tank float switches.

System Operations

Second primary tank pumps are in Orenco Biotube Pump vaults (Appendix D). Dosing tank pumps are placed in Orenco Flow Inducer Towers as shown on the as-built plans in Appendix D.

The two secondary tank pumps are transfer pumps and operate based on float settings and programmed timing. It is thought that they cycle together with a transfer rate of 100 gpm for two minutes, off for 12.4 minutes and then on again for 2 minutes until the time float switch lowers to the off position.

The dosing tanks utilizes of (3) pump sets each consisting of (2) pumps. Each pump set is programmed to run for (2) minutes followed by all pumps being off for (12) minutes, followed by a (2) minute run time for the next pump set. The three pumps sets continue this cycle until the time float switch is lowered to the off position. Each pump discharges to its own distribution valve with each being dedicated to its own chamber bed each which consists of (6) chamber rows. Pump timing inputs shown in Appendix D

2.0 SCOPE OF WORK

The scope of this project is to repair the CSWS so that the discharge pumping capacity is returned to the original design intent. This project calls the following actions to be taken:

1) Remove (8) pumps and replace with (8) new pumps.

2) Check all wiring to pumps – check for damage, electrical continuity. Repair damaged wire as needed.

3) Ensure proper operation of all system pumps, floats, and timers.

4) Check system programming to ensure pump cycling is in accordance with original design intent. Reprogram system if needed.

NPT SS discharge is 2 7⁄8 in. hexagonal across flats. Discharge is female NPT threaded, U.S. nominal size, to accommodate Orenco® discharge hose and valve assemblies. Consult your Orenco Distributor about fittings to connect hose and valve assemblies to metric-sized piping.

2 Minimum liquid level is for single pumps when installed in an Orenco Biotube® Pump Vault or Universal Flow Inducer. In other applications, minimum liquid level should be top of pump. Consult Orenco for more information.

3 Weight includes carton and 10-ft (3-m) cord.

4 High-pressure discharge assembly required.

5 Do not use cam-lock option (Q) on discharge assembly.

6 Custom discharge assembly required for these pumps. Contact Orenco.

7 Capacitor pack (sold separately or installed in a custom control panel) required for this pump. Contact Orenco.

Using a Pump Curve A pump curve helps you determine the best pump for your system. Pump curves show the relationship between flow and pressure (total dynamic head, or TDH), providing a graphical representation of a pump’s optimal performance range. Pumps perform best at their nominal flow rate. These graphs show optimal pump operation ranges with a solid line and show flow rates outside of these ranges with a dashed line. For the most accurate pump specification, use Orenco’s PumpSelect™ software.

Universal Biotube® Pump Vaults

Applications Orenco Biotube® Pump Vaults are used to filter effluent that is pumped from septic tanks or separate dosing tanks in STEP systems and onsite wastewater treatment systems. They remove two-thirds of suspended solids, on average. Pump vaults house a Biotube effluent filter and one or two Orenco high-head effluent pumps and can be used in single-compartment septic tanks with flows up to 40 gpm (2.5 L/sec). When flows are greater than 40 gpm (2.5 L/sec), a double-compartment sep-tic tank or separate dosing tank is recommended.

For use with Orenco® 4-inch (100-mm) Submersible Effluent Pumps

General The Orenco Biotube Pump Vault includes a molded polyethylene hous-ing with an internal Biotube filter cartridge constructed of polypropylene and PVC. Schedule 80 PVC support pipes are included to suspend the vault in a tank opening. “Earless” 68-inch (1727-mm) vaults, which rest on the bottom of the tank instead of on support pipes, are also available.

The filter cartridge can be removed without pulling the pump or the vault.

Effluent enters through inlet holes around the perimeter of the Biotube vault and flows through the Biotubes to the external flow inducer. The external flow inducer accommodates one or two pumps. Orenco Biotube Pump Vaults are covered by U.S. patents #4,439,323 and 5,492,635.

Flow Inducer Towers Applications Orenco® flow inducer towers are designed for use in commercial/ municipal recirculation and final discharge tanks following secondary treatment, where filtration is not required. Flow inducer towers can be ordered to house from two to five of Orenco’s 4-in. submersible efflu-ent pumps.

General The base of the flow inducer tower rests on the bottom of the tank and the top of the flow inducer tower extends at least eight inches into the riser. For tanks with curved bottoms, an Orenco vault basin (VB1806-FRP) is necessary to create a flat surface on which the flow inducer tower can rest. The pumps sit on raised fiberglass platforms inside of the 5-inch (127-mm) diameter Class 125 flow inducer tubes.

A float bracket is attached to the tower to accommodate an Orenco float assembly.
