Water AuditingM & V

(Measure & Verify)

How It’s Done

Determine where water is being used in the facility

Examine and analyze all areas of water use

Calculate and account for water use

Propose site specific measures to reduce water use

Information Review

Determine savings and provide a cost benefit analysisEnd Result

Traditional Methods of Data Recording

• Walk through site.• Write down data.• Take pictures• Enter data into

spreadsheets.• Enter data into computer.• Re-enter to calculate

savings and cost.• Write proposal.

WMI’s Method of Data Recording

• Walk through site.• Input data to tablet.• Take pictures with tablet.• Upload to cloud.• Download to calculate.• Write proposal.

WMI utilizes the newest technology to streamline the auditing process.

• Use of tablets and software developed specifically for audits reduces mistakes and increases efficiency.• Project-defined data entry.• Building and room oriented domestic fixture entry.• Fixture specific list of needed data.• Drop-down menus for all data inputs.• Pictures taken are logged with building and room ID’s.

• All project data is synced to our server, where it can be downloaded anywhere in easy-to-read Excel spreadsheets.

Smarter Auditing Technology

• Reducing redundant keying of data from application to application. • Reducing the time it takes to get the information from the field to the

office. • Reducing errors from paper notes to be transcribed and rekeyed. • Increasing the ability of field staff to capture graphical representations

of buildings and obtaining customer signatures in the field. • Allowing bar code scanning of the inventory item used on a job.
