MUD and Utility Director Workshop PRELIMINARY AND SUBJECT TO CHANGE

THE INFORMATION CONTAINED IN THIS WORKSHOP PRESENTATION IS PRELIMINARY IN NATURE AND IS INTENDED TO SERVE AS A PLANNING REFERENCE ONLY. Note: The time references related to the 2025, 2035 and 2045 “Service Areas” are intended to signify the various phases of project development and are not to be interpreted as being converted to alternative/surface water within those time horizons. For example, not all of the 2025 Service Area (Blue Areas) will be converted by calendar year 2025.

February 1, 2018

Meeting the Subsidence District Goals • Harris Galveston Subsidence District 2013 Regulatory Plan • 2010 – 30% Conversion to Alternative Water • 2025 – 60% Conversion to Alternative Water • 2035 – 80% Conversion to Alternative Water

– 2018 Disincentive Fee $8.75 per 1000 gallons

The NHCRWAs primary assignment is to develop and implement a strategy for complying with the Harris-Galveston Subsidence District’s Regulatory Plan that requires a reduction in groundwater usage to no more than 20 percent of total water demand by the year 2035.


3

Meeting the Subsidence District Goals • Harris Galveston Subsidence District Tools • Over-Conversion Credits • Water Education/Conservation Credits • Water Reuse

The Authority can employ any or all of these tools to meet the HGSD mandates. The approach the Authority elected to use is aligned with the Board directive to keep water rates as low as possible for as long as possible.


4

Meeting the Subsidence District Goals Two major components to achieve the Authority’s Assignment:

 Participation in large-scale “Regional” Projects o Luce Bayou Interbasin Transfer Project o Northeast Transmission Line o Northeast Water Purification Plant Expansion
