January 1990 marked the inception of construction activities by the Imperial Irrigation District (IID) to implement 15 new projects in the Water Conservation Program (Program). 

These projects were identified in the landmark December 1988 Water Conservation Agreement (Agreement) between IID and the Metropolitan Water District of Southern California (MWD) and in the December 1989 Approval Agreement among IID, MWD, Palo Verde Irrigation District (PVID) and Coachella Valley Water District (CVWD). 

Major construction work was completed in December 1997 while construction of the last project was completed in September 1998.  While the Program focused primarily on modernizing and rehabilitating IID's distribution system, it included on-farm water management projects that permit greater water management flexibility for farmers and opportunities for farmers to apply water more effectively.  In some cases, distributuion system and on-farm management improvements are so interrelated that they increase the effectiveness of each project on the Program.
