512-294-7193
Presented at WaterSmart Innovations 2015
The water industry is entering the era of BIG DATA!
• AMI metering
• Portfolio manager data base now includes water use
• The new LEED requires sub metering and five years of water use data to be sent to the USGBC
• Many States have intensified water use data gathering
• New billing systems are becoming much more data rich
What will be covered
1. Time Series Analysis;
2. Utility ICI Sales and Use;
3. How water is actually used; and
4. Benchmarking ICI water use.

Benchmarking Energy and Water Use In Commercial Buildings
The Star indicates benchmarking water use.
SB 700 requires that the Texas State Energy Conservation Office
(SECO) to benchmark energy and water use in State Facilities and State supported Institutions of
Higher Education.
Beverage Industry Environmental RoundtableBIER
Conclusion• The numbers can help determine the effectiveness of your program;
• The numbers can help identify area in the ICI community that off great potential;
• The numbers can help identify what areas within a facility offer the greatest potential for savings;
• The numbers can tell how much of the water you sell is used by which sector; and
• The numbers can help identify specific entities that may offer the largest potential.
But you have to put the numbers together!
Are you ready for this avalanche of BIG DATA, and are you capable of analyzing
the information?
