TECHNICAL MEMORANDUM
SUBJECT: | Snake/Salt River Basin Plan Basin Water Use Profile – Municipal |
PREPARED BY: | Sunrise Engineering, Inc. |
DATE: | May 2, 2002 |
Introduction:
This memorandum covers the topic of municipal water uses in the Snake/Salt River basin. The majority of the population in the basin is located in valleys along the Snake and Salt Rivers, although water used for municipal purposes comes from sources other than those rivers. The following towns, communities, subdivisions, and water systems are included in this memorandum:
Incorporated municipalities with primary groundwater sources:
Other entities with primary groundwater sources:
The following community also obtains water from groundwater sources in Wyoming, however the town itself is located in Idaho:
There are no entities in the basin that obtain water from surface water sources.
Appendix A contains summaries of each municipal water user in the basin.
Methodology:
While investigating the use of water for municipal purposes, it was recognized that only four of the communities in the basin are incorporated municipalities. Many other systems serving various unincorporated communities or subdivisions also provide water for municipal type uses, and it was felt that these systems should also be included in the municipal portion of the basin water use profile. In order to have a consistent method of determining whether or not to include a particular system, it was decided that the EPA definition of a Community public water system should be used. According to the EPA website, “Public water systems provide water for human consumption through pipes or other constructed conveyances to at least 15 service connections or serves an average of at least 25 people for at least 60 days a year.” Public water systems are further defined by EPA as Community, Non-Transient Non-Community, and Transient Non-Community. EPA states that a Community water system “supplies water to the same population year-round.” A Non-Transient Non-Community system “supplies water to at least 25 of the same people at least six months per year, but not year-round. Some examples are schools, factories, office buildings, and hospitals which have their own water systems.” A Transient Non-Community system “provides water in a place such as a gas station or campground where people do not remain for long periods of time.” Using this method of classification ensured that municipal type uses were looked at collectively, while other uses such as schools, restaurants, and dude ranches were included in other portions of the basin water use profile, such as domestic use.
Information regarding municipal use of water in the basin was primarily obtained from the 2002 Water System Survey Report produced by the Wyoming Water Development Commission. Interviews were also held with representatives of some of the water systems to obtain additional information, such as water use records. If information was not available for a particular system in the 2002 Survey Report, the 2000 Survey Report was used, as well as EPA Sanitary Surveys of various dates. Past studies conducted on various water systems were also consulted for additional information.
Many of the water systems in the basin utilize water from spring sources. Were it not for the municipal depletion, this water would enter a stream and flow through the surface water system. Thus, the municipal use in the basin in reality does have an impact on surface water, although water is not diverted from a surface source directly. However, upon further review of this situation, the amount diverted is not significant. For example, the average water use in Afton, which obtains a majority of its water from spring sources, is approximately 1.25 MGD. This corresponds to less than 2 cfs, which is considered minor when compared to other surface water diversions such as irrigation headgates. This is in light of the fact that Afton represents the largest spring source use in the basin, and many other spring users only divert a fraction of the above amount. Due to the fact that the depletion from a major municipal use equates to the depletion of a minor irrigation use, it was determined that the depletions from the various municipal and community systems due to spring sources would not be included in the surface water modeling effort.
Some wastewater treatment systems discharge water to a river or stream following collection and treatment of the wastewater to appropriate standards. A majority of the systems covered in this memo utilize individual wastewater disposal systems, such as septic systems. The incorporated municipalities do have wastewater collection and treatment systems, however the majority do not necessitate discharge. Only two systems in the basin have flows that return directly to surface water following the treatment of wastewater. These flows represent an increase to the stream flow, and are quantified in Table 1. Similar to the discussion regarding surface water depletions due to use of springs, the quantity of water discharged and returned to the surface water system is minor, and it was determined that these inflows would not be included in the surface water modeling.
Conclusions:
Table 1 provides a summary of basic data on each municipal system in the basin, such as population, water sources, and general water use rates. Table 2 lays out the peak demands experienced by each system, and how these demands compare with the capacity of the system and the current water rights held by each entity. As stated previously, Appendix A contains a summary of the water system for each municipality or community in the basin.
