Preliminary Sewer Basis of Design Report Page 1

1. INTRODUCTION

1.1. SUMMARY OF PROPOSED DEVELOPMENT:

The report presents the service requirements of fourteen new single-family residential lots located on

17.5 acres of land located at the northwest corner of Scottsdale Road and Dixileta Drive. The purpose

of this report is to provide an analysis of the impact that this development will have on the city’s

wastewater system.

1.2. LEGAL DESCRIPTION:

The property is located in the Southeast quarter of Section 22, Township 5 North, Range 4 East of the

Gila and Salt River Base and Meridian, Maricopa County, Scottsdale, Arizona.

Refer to FIGURE 1 - Vicinity Map for the project’s location with respect to major cross streets.

2. DESIGN DOCUMENTATION

2.1. DESIGN COMPLIANCE:

The proposed sewer system is designed to meet requirements of the City of Scottsdale (“the City”)

Design Standards and Policies Manual (DS+PM), the Arizona Department of Environmental Quality

(“ADEQ”), and Maricopa County Environmental Services Department (“MCESD”).

2.2 PROCEDURES, POLICIES AND METHODOLOGIES:

The 18” sewer line in Scottsdale Road is evaluated in the City’s wastewater model for uses included in

the 2012 Water Reuse Master Plan Update, therefore, no sewer monitoring of this pipe is proposed.

Pipe flow, velocity and depths of the proposed sewer lines will be analyzed using Bentley FlowMaster®.

3. EXISTING CONDITIONS

3.1. EXISTING ZONING & LAND USE:

Land ownership includes approximately 17.5 acres of vacant land presently Zoned R1-70 ESL FO.

3.2. EXISTING TOPOGRAPHY, VEGETATION AND LANDFORM FEATURES:

The undeveloped site slopes to the southwest at 2% grade with thirty feet of fall across the site.

FIRM Map Number 04013C0895L dated October 16, 2013, indicates the northwest corner of the site

lies in designated Zone “AO” with a 1-foot depth and 3 fps velocity . That portion of the site with

proposed lots lies outside the designated flood plain. Refer to FIGURE 2 for an aerial of the overall

project existing conditions and FIGURE 3 for the FIRM Map.

5-PP-20218/25/2021



3.3. EXISTING UTILITIES:

Sewer: City of Scottsdale (QS 53-44) - see FIGURE 4.

• An existing 18” VCP sewer line is located in Scottsdale Road within the northbound travel lanes.

• No sewer lines exist in Dixileta Drive or sewer services/stubs to the site.

3.4. FLOW MONITORING:

Flow monitoring of the 18” sewer line in Scottsdale Road is not necessary as this is a trunk line included

in the City’s master plan and sewer model. The City will verify capacity for this project.

4. PROPOSED CONDITIONS

4.1. SITE PLAN:

Proposed development consists of 14 single-family residential lots with access off a proposed cul-de-

sac extended north from Dixileta Drive. The property is requesting rezoning to R1-43 ESL FO.

4.2. PROPOSED SEWER SYSTEM:

A sewer cannot be extended along Dixileta Drive to serve this project because the topography drops off

to the west quickly and cover is not adequate over the sewer, reaching as little as 2 ft. A new manhole

will be constructed to connect to the public system per M.A.G. 440-3, over the existing 18” VCP north

of the Dixileta Drive intersection and extended into the site within a tract between lots 13 and 14.

Approximately 750-feet of 8” sewer pipe will be extended west and north in the cul-de-sac providing

sewer service to the 14 lots. Lots (1&14) near the southern end of the site may require individual on-

site ejector systems as building finish floors dictate. Any necessary ejector lines will be privately

owned, operated and maintained by the property owner and constructed within private easements.

Manholes receiving ejected wastewater will be lined. Lots with building pads lower than the next

upstream manhole will require backwater valves per DS+PM Sec. 7-1.409 G.

Topography prohibits extension of onsite sewer to the 71st Street alignment between Lots 3 and 4. See

APPENDIX I for the Preliminary Utility Plan.

4.3. MAINTENANCE RESPONSIBILITIES:

The on-site sewer main will be public and located in an easement/tract or right-of-way dedicated to the

City of Scottsdale. Therefore, the on-site and off-site sewer system will be public and maintained by the

City. As previously stated, any required ejector lines will be owned, operated and maintained by the

respective property owner and placed within private easements outside of any right-of-way or public

utility easement.

5. COMPUTATIONS

5.1. SEWER DEMANDS:

The proposed daily demands are shown in TABLE 1 below. Average day sewer demands are described

in Section 7-1.403 of the City of Scottsdale’s Design Standards & Policies Manual.

5.2. VARIANCE FROM STATED DESIGN FLOWS:

No variance from the applicable design criteria is being requested.

5.3. SEWER SYSTEM ANALYSIS:

The proposed 8” pipe has adequate capacity to provide service to the 14 lots. A few of the southern

lots may need to provide onsite ejector systems to discharge up to the gravity line in the cul-de-sac.

The feasibility of extending the sewer west to 71st Street between lots 3 and 4 resulted in inadequate

cover (less than 2 feet).

Reference APPENDIX II for the pipe hydraulics and APPENDIX III for a sample ejector spec..

6. SUMMARY

6.1. SUMMARY OF PROPOSED SEWER IMPROVEMENTS:

The proposed sewer extension will be adequate for providing service to this subdivision. Topography

does not permit any extension further west or north to accommodate adjacent properties.

6.2. PROJECT SCHEDULE:

The infrastructure and building pads are proposed to be constructed in a single phase.

PRESSURE SEWERSYSTEMS

Sewer Anywhere and SaveE/One Sewer Systems give engineers, builders, developers, municipal sanitarians and land planners unprecedented new freedom in land usage and sewer rehabilitation.

Easy to install. Easy to operate. And easy to maintain.

The sensible sewering solution that defies gravity and saves up to 50% – the E/One sewer system.

Environmentally sensitive. Economically sensible.™

E/One, Extreme, Engineered to do One Job Perfectly and Environmentally Sensitive Economically Sensible are trademarks for Environment One Corporation. Copyright 2016 Environment One Corporation. All rights reserved throughout the world.

NOBODY CAN TOUCH OUR CURVE.In a low pressure system, constant, predictable pump output is the foundation for proper hydraulic design. It enables the engineer to minimize retention time, pump wear, and keep scouring velocity at effective levels.

Environment One’s semi-positive displacement, progressing cavity pump has a nearly vertical H-Q curve. It is by far the most “forgiving” pump design – providing predictable flow over the full range of typical system pressures; strengths critical in a large-scale, low pressure sewer system.

E/One’s superior high head capability allows a system with few, if any, lift stations. And, it easily accommodates additional future connections without compromising system performance.

These E/One pump characteristics translate into:

• predictable hydraulic design

• lower collection system capital costs

• less maintenance

• lower operating costs

High Heads/Negative Heads. Industry’s most reliable operation – rated for continuous duty of negative head to total dynamic head of 185 feet reduces the number of lift stations and pipe sizes. This cuts costs – both initially and in long-term operation and maintenance.

Constant Flow. The system pressures to be overcome by any given grinder pump in a low pressure system vary dramatically over the course of a day. E/One’s progressing cavity pump readily accommodates these pressure variations while maintaining a nearly constant flow without ever operating at “near shut off” – thus avoiding the wear and motor burn-out suffered by other pump types.

High Grinding Torque. Our unique pump system, driven by a one-horsepower motor turning at 1725 rpm, produces grinding torque greater than a larger horsepower pump turning at twice the speed.

Energy Efficient. The pump is activated automatically and runs for short periods.

Low Maintenance Submersible Motor.Low maintenance and long life are the hallmarks of our air-filled motor. Permanently lubricated ball bearings and Class F insulation eliminate the need for periodic oil changes and oil disposal costs required by oil-filled submersible motors.

Large-Diameter Grinder Assembly. Almost twice the diameter of most other types of grinder pumps, contributing to a dramatic reduction of inflow velocity for less wear and no blinding, clogging or jamming.

No Preventive Maintenance. Non-fouling static level sensors require no preventive maintenance. Because of our unique, near constant discharge rate, no main line flushing is required in a properly designed system.

Corrosion Resistance. Corrosion resistance is built into the E/One® design.

Serviceability. Our unique core design eliminates the need for in-field troubleshooting and pump servicing. This means lower maintenance costs and minimum homeowner inconvenience.

ENGINEERED TO DO ONE JOB PERFECTLY.™

At the heart of the E/One Sewer System is the toughest, hardest working pump in the industry. The new standard in excellence, durability, and longevity, the E/One Extreme Series Grinder Pump. Its evolution refl ects everything we’ve learned in more than 40 years as the originator and leader in the category of low pressure sewer systems.

The pump stations incorporate the grinder pump, motor controls and level sensing device integrated into a compact unit, easily removable for servicing when necessary.

And, the geometry of the pump not only produces a near-vertical pump curve, it also allows passage of ground solids without clogging. Because of the low rpm and highest quality components, we experience the lowest service call rate in the industry. An average mean time of 10 years between service calls is typical.

The W-Series is E/One’s most versatile grinder pump station – a range of basins, covers, discharges, inlets and panels are available. Simplex through quadriplex stations work with single homes, light commercial applications, or several homes.

The W-Series allows you to choose integral components for optimal installation and performance for your site’s conditions. Whatever tank size is needed, many features from discharge configuration to panel options can be adjusted to your specific needs. W-Series stations can have one pump or up to four pumps, depending on the tank chosen.

Simplex Stations

• HDPE or fi berglass (not shown) construction

• Station capacities of 100, 237 and 476 gallons available

• Various station heights available

Multiple-Pump Stations

• HDPE construction

• Station capacities of 476 and 486 gallons available

• 476-gallon tank allows for 1 or 2 pumps

• 486-gallon tank allows for 2, 3 or 4 pumps


The W-Series fi berglass tanks offer a multitude of station volumes and heights with diameters from 24 inches to 72 inches, and heights from 60 inches to 240 inches.

* Please visit www.eone.com for application and fl ow information

The E/One D-Series features a wetwell/

drywell design that provides a dry accessway

for ease of service. Plus a modular design

and one-piece core that permits simple

core replacement – should it ever become

necessary. Available in both simplex and

duplex grinder pump stations to fi t a wide

variety of applications, from single-family

homes to light commercial applications to

several homes in conjunction.

The tanks are made from tough, corrosion-

resistant HDPE for long life and zero upkeep.

Station capacities of 70 gallons to 500 gallons

are available.

THE W-SERIESEngineered for choice.

More builders and municipalities are opting for the ease and convenience of the E/One Indoor Unit, which offers easy access along with all the benefits of the D-Series. An attractive self-contained unit, the I-Series fits unobtrusively into a basement or garage with a clean, contemporary design that feels right at home with other major appliances.

It can be used as part of a new E/One sewer system or retrofit into an existing low pressure or gravity sewer system.

With its quiet, energy-efficient pump and sound insulating properties, the I-Series is easy to live with.
