Supply Water Treatment Outage Consequences • When pumps go offline due to power outages, these processes are halted and water distribution ceases. • In the case of large municipalities, returning all plant systems to normal operations and resuming the distribution of water can be a daunting task. •
Slide 14: Water Treatment Outage Consequences (Cont’d)
Water Treatment Outage Consequences (Cont’d) • Water distribution facilities are the heart of the water network, responsible for pumping water through the system. • A power outage that disrupts pumping or lifting stations can put a significant strain on the network, potentially leading to flooding o

Slide 22: Generator Selection/Sizing: Fuel Choice
Generator Selection/Sizing: Fuel Choice • Due to fuel shortages caused by extended outages that were the result of recent hurricanes, larger onsite fuel storage is now being required in some regions. • Fuel testing requirements for diesel fuel tanks must also be considered. Power Hour Related Consid
Slide 23: Generator Selection/Sizing: Fuel Choice (Cont’d)

Slide 24: Generator Selection/Sizing: Rating Types
Generator Selection/Sizing: Rating Types What type of rating is appropriate for Water and Waste Water applications? Industry Standard for Generator Set Ratings: • ISO 8528: Standard for reciprocating internal combustion engine driven alternating current generator sets. • Defines application, ratings
Slide 25: Emergency Standby Power (ESP)
Emergency Standby Power (ESP) Spec Note: If a generator set is only utilized for emergency backup, not demand response or rate curtailment, then, a Standby rating should be specified. Prime and Continuous ratings are not properly suited for emergency backup applications as this can cause the generat
Slide 26: Why Customers Need or Want a Tier 4 Solution for Diesel?
Why Customers Need or Want a Tier 4 Solution for Diesel? Need • to operate outside of the emergency standby limitations set forth by the EPA.

Additional Design Considerations 31
Slide 32: Power Transfer Design Considerations (Open Transition)
Power Transfer Design Considerations (Open Transition) • An Automatic Transfer Switch (ATS) or breaker pairs can be used for transferring power from one source to another. • In applications where a significant portion of the loads are motors, the design must be cognizant when switching between two l
Slide 33: Residual Voltage Decay
Residual Voltage Decay Voltage decays exponentially (independent of motor speed) NEMA MG-1 recommends a delay of 1.5 Motor Open Circuit Time Constants • Voltage will be at 22% of nominal For multiple motors, use the time delay for the largest motor 22% of nominal voltage (safe transfer) Residu
Slide 34: Design Considerations (Closed Transition Transfer)
Design Considerations (Closed Transition Transfer) • If closed transition (make-before-break) is being considered, be sure to verify acceptability with local utility at least six months in advance. • ATSs cannot anticipate a power failure. The site will experience a power outage if the utility unexp
Slide 35: Design Considerations (ATSs / Switchgear)
Design Considerations (ATSs / Switchgear) • If transfer switches or gear will be located outdoors, be sure to verify site environmental requirements. Often, NEMA 3R or 4X enclosures with anti-condensation heaters are required. • Ensure that switchgear busses are plated with a material compatible wit
Slide 36: Design Considerations (Switchboard/Switchgear)
Design Considerations (Switchboard/Switchgear) • Switchboard/Switchgear/Metal-Clad Switchgear size and accessibility are important factors when designing installations. • Specifying front access only ATSs and switchboards provide an advantage by not requiring rear access, which will allow the gear t
