WHCRWA
¨ Created in 2001 – HB 1842 approved in 77th Texas Legislature
¨ Primary Purpose: ¤ Acquisition of surface water for residential, commercial and industrial
uses
¤ Reduction of groundwater withdrawals; 30% by 2010 goal met, 60% by 2025, 80% by 2035
¤ Conservation, preservation, protection, recharge and prevention of waste of groundwater for control of subsidence in western Harris County

Lessons Learned
1. Allow end users to have input into system requirements
Understand user’s needs… capture support
2. Keep application designs SIMPLE and EASY to USE and MAINTAIN
Users often abandon new technologies for more familiar manual methodologies
3. Develop solid design specification documentation that will guide the developer to build exactly what the user base needs
Not what the developer or GIS Analyst believes is needed… intuitive easy to operate… not encrypted with multiple activity layers to accomplish a single function
4. Set up a mirrored test environment that matches production
Isolated staging system for testing and recovery activities
5. Apply regression testing techniques to test the entire application for new bugs introduced during code enhancement and modifications
New code creates new problems elsewhere… be sure to catch all before releasing enhancements to the user base
