根据与南加州大都会水区20个成员机构合作进行的900多个商业、工业和机构（CII）用水审计得出的信息，发现翻新卫生设备是广泛推荐的节水措施。对审计数据的仔细检查表明，对于大多数CII现场，卫生设备是节约用水的最佳机会。跟随- 对审计参与者的电话采访表明，需要财政激励，才能更频繁地进行这些改造。有了这些信息，伦敦大都会董事会于1997年10月批准了最初的CII退税计划。该返利计划允许大都会为节水更换或改造措施的扩展列表（菜单）提供资金，特别是:超低冲洗（ULF）厕所和小便器；ULF马桶冲水器改装套件； 预先冲洗喷头；高效（水平轴）洗衣机；冷却塔电导率控制器。1998年8月，Metropolitan与COMPAC成员机构合作，提议改进和扩大其现有的菜单返利计划，以便在整个地区范围内实施。在不改变大都会董事会批准的菜单返利计划基本前提的情况下，新的区域性试点返利计划将:通过区域性重点扩展现有计划； 针对具有最高节水潜力的终端用户进行营销；此外，增加回扣，以激励最终用户更换高使用率的固定装置和设备。包括桌子。

Based on information developed from over 900 commercial, industrial, and institutional (CII) water-use audits conducted in cooperation with 20 of the Metropolitan Water District of Southern California's member agencies, it was found that retrofitting sanitary fixtures was a widely recommended measure for saving water. Closer examination of the audit data showed that for most of the CII sites, sanitary fixtures represented the best opportunity for water savings. Follow-up phone interviews with audit participants indicated that financial incentives were needed for these retrofits to occur on a more frequent basis. Armed with this information, the original CII Rebate Program was approved by the Metropolitan Board of Directors in October 1997. The Rebate Program allowed Metropolitan to offer funding for an expanded list (MENU) of water-saving replacement or retrofit measures, specifically: ultra-low flush (ULF) toilets and urinals; ULF toilet flushometer retrofit kits; pre-rinse spray heads; high-efficiency (horizontal-axis) clothes washers; and, cooling tower conductivity controllers. In August of 1998, Metropolitan, working with COMPAC member agencies, proposed that its existing Menu Rebate Program be improved and expanded to provide for a regionwide approach to implementation. Without altering the basic premise of the Metropolitan Board approved Menu Rebate Program, the New Regionwide Pilot Rebate Program would: expand the existing program through a regionwide emphasis; target marketing efforts toward end-users with the highest potential water savings; and, increase rebates to motivate end-users to replace high-use fixtures and equipment.
