Such rates require the deter- mination of revenue requirements by customer class before designing and adopting a rate structure. Recognizing the limitations

27、Manual M1 may have for smaller systems, or larger sys- tems without sufficient data or rate-making capability, the AWWA Rates and Charges Committee (authors of Manual M1) developed the idea for a “Manual M1-type” alterna- tive. A rate manual for small systems provides guidelines for the development

28、of rates for utilities that lack the data and resources needed to apply the methods described in Manual M1. For these utilities, this manualDeveloping Rates for Small Systemsprovides guidance in developing rates when data and information may be lacking. The Rates and Charges Committee encourages all

29、 utilities to use Manual M1 as the primary guidance tool but believes this manual fills a need for small systems. INTENDED AUDIENCE This manual is intended to serve as a resource for managers (and others) of small water s y s t e m s i n t h e d e t e r m i n a t i o n o f r a t e s f o r w a t e r

30、s e r v i c e . O t h e r r e s o u r c e s , f o r e x a m p l e , M a n - ual M1 and state and local government agencies, may also be of value in the prepara- tion of rates for small systems. However, this manual focuses on the unique attributes of small systems as related to financial planning an

31、d rate design. Managers and operators of small systems and their advisors (financial, accounting, and engineering professionals) should find this manual useful in preparing water rates that recover costs using generally accepted cost-based practices. For purposes of this manual and for those who mig

32、ht benefit from its use, there is no reason to specifically define a small system in terms of connections or population. Rather than define a small system in either of these terms, and therefore restrict or limit the appli- cability of this manual, the characteristics of the systems to which this ma

At the same time, this manual may not be applicable for many water systems. Systems with a rapidly growing or diverse customer base,

36、those with a large industrial customer or customer base with signifi- cant outside city or wholesale service arrangements, or those with contracts requiring cost-of-service based rates should refer to Manual M1 for guidance in financial planning, cost allocation methods, and rate design. Systems see

In addition, Manual M29, Water Utility Capital Financing, should be reviewed as well when developing a financial plan. UNDERLYING FINANCE AND RATEMAKING PRINCIPLES The AWWA has establ

38、ished policies for finance, accounting, and rates. These AWWA policies provide direction to AWWA members and the volunteers that produced this manual. These policies are updated and generally available from AWWA. The policies included in the preparation of this manual were those revised by the Board

39、 of Directors on January 17, 2010. The relevant AWWA policies for this manual include: 1. Water utilities revenues from water service charges, user rates, and capital charges (e.g., impact f e e s a n d s y s t e m d e v e l o p m e n t c h a r g e s ) s h o u l d b e s u f c i e n t t o e n a b l e
