Smart Water Meters

• AMI: Advanced Metering infrastructure

• Two way communication • Automated reading • Hourly or better usage resolution

• Conservation Benefits ~7% • Customer Leak detection • Conservation monitoring • Drought compliance

Presenter

Presentation Notes

Pacific Institute estimates household leak repair can save 430K AF per year; CA DWR 7%

Smart Water Meter • Private radio network: Utility builds

own network • Wide area network, e.g. on top of

electric utility smart meter • Cellular network Few standards on “smart”

Beacon smart meter example, leak at 300 gph but could be 1 gph. Customer portal or utility portal.

Meter only part of solution

• Smart meter tells customer he has a leak, not where

• Larger leak problem is on the utility side of meter ~15%

Opportunities • IoT based leak detection for

utility • Virtual metering for losses

between utility/customer Leak detection the old fashioned way AWWA

Why Water Sub metering? • Tenant billing • Building management

• Conservation driven, e.g. LEED • Best practice building management

• On site recycling • Conservation codes • Rebates • Billing

LEED Leadership in Energy and Environmental Design

Tenant billing: Multifamily Residential Long desired MF sub-metering: -Provides incentives and metrics -Reduces MF consumption 15-25% -Retrofit labor cost high Game changer: -Sub-meters in CA MF next year -Rebates for sub-metering (SCVWD) Tenants rights: Proper billing, notice, cutoffs, late fees, calibration, fees

Opportunities: • Easy install smart sub-meters • Water monitoring software • Tenant billing software

Presentation Notes

Sustainable business practices are increasingly important to businesses today. Concerns about the environment and sustainability are often at the forefront of the business plans for large and small companies alike. “Going green” is not only good for the environment, but also having more efficient practices and processes help to reduce cost. In California one of the ways companies show their commitment to sustainability is by getting new and retrofitted buildings LEED Certified. There are four types of LEED Certifications: Bronze, Silver, Gold and Platinum. These certifications are awarded based on a points system of various measures taken to improve sustainability and lessen the footprint. One of the main pillars of LEED Certification has to do with Energy efficiency. It accounts for more points than any other category. Sub metering is not only helpful, but necessary to achieve many of these points. In one instances you must prove that you have been able to reduce energy usage by a certain percentage to achieve the points, which can only be done with the help of sub metering. However, there are multiple questions about actual effectiveness of LEEDs. Several jurisdictions have removed LEED Certification as a requirement. Focus on the actual energy performance of your building.

Building management Indoor Water leaks #1 insurance claim! • Damage, loss of use, mold Best practices: • Leak detection near fixtures • Tenant sub-meters • Critical system sub-meters, e.g. sprinklers • Remote management system: smart sub-meters,

shutoff valves, integration with BMS • Payback with one sensed leak

Opportunities: • Low cost smart sub-meters • Easy install sub-meters, e.g. no pipe

cutting • Cloud based management • Tenant billing software

On-Site Reuse: SF example On site reuse requirements: • SF new large buildings • Other cities: large

campuses Sub metering needed: • LEED measurement • Measured rebates • Bragging rights Opportunities • Reuse technologies • Sale/purchase • Retrofit

Presentation Notes

The customer sees an overall savings from their original bill, resulting in a water purchase agreement payment and a significantly smaller utility payment.

On site recycling: laundry water

Sub-meters essential to business: • All treated water • Make up water • LEED compliance • Rebates Challenges • Power loss on meter but not

pump • Meter clogs • By pass loops in the water • Accuracy differences vs.

utility meter
