LNWB Ch08 Water Management - industrial, residential, and commercial water use - data

The Lower Nooksack Subbasin is comprised of a variety of land and water uses both agricultural and nonagricultural. The water uses, described in this chapter include municipal, industrial, residential, and commercial. The following analysis of nonagricultural water use is divided into three sections: municipal/industrial, residential, and commercial/industrial.

The utilities that serve municipal/industrial customers in the Lower Nooksack Subbasin include the City of Bellingham, the City of Everson, the City of Ferndale, the City of Lynden, and the PUD #1 of Whatcom County. For these utilities, large municipal user water system records were obtained for years 2007 through 2011. Averages for this five year period were used in the model for water use, return flows, and interbasin transfers. The average annual diversion by the large utilities municipalities in our analysis totals nearly 25 cfs, 82% of which are transferred out of the Nooksack basin. The majority of that water serves Cherry Point industries; a small amount serves out-of-basin irrigators.

Residential, or domestic, water use was estimated according to population. Population and per capita water use rates are the foundation for calculating an average daily residential water use for each drainage in the Lower Nooksack Subbasin. 2010 Census geospatial census data were used to calculate the population for each drainage. The 2010 population for the Lower Nooksack Subbasin was 46,204, up 8,345 since the 2000 census. A per capita demand rate of 88 gallons per capita per day was agreed upon by the WRIA 1 Joint Board Staff Team to use as input along with the new population numbers. Seasonal demand factors were also determined to distribute monthly water use such that maximum demand occurred in the summer months and minimum demand in the winter.

Businesses and other operations that are not supplied water by a municipality are either served by a smaller public water system or are self-supplied. For commercial users not within the service area of the municipalities listed above, water use was estimated based on average use rates agreed on in 2003 with the WRIA 1 Water Quantity Technical Team. Commercial use was based on the type of operation identified in the Whatcom County Assessor records.

下诺基斯克次流域包括农业和非农业的各种土地利用和水域利用。本章所述的水域利用包括市政、工业、住宅和商业用水。对非农业用水进行的以下分析分为三个部分：市政/工业、住宅以及商业/工业用水。

服务下诺基斯克次流域市政/工业客户的公用事业包括贝尔林厄姆市、埃弗森市、费尔内尔市、林登市以及惠康县公共事业局第1号。对于这些公用事业，获取了2007年至2011年期间的大型市政用户水系统记录。使用这五年的平均值来构建模型，以模拟用水、回水以及流域间转移。大型公用事业市政用户的平均年用水量总计接近25立方英尺每秒，其中82%的水被转移出诺基斯克流域。大部分的水服务于樱桃点产业；一小部分服务于流域外的灌溉者。

住宅或家庭用水量是根据人口进行估算的。人口和人均用水率是计算下诺基斯克次流域每个排水区平均日住宅用水量的基础。2010年人口普查的地理空间人口普查数据被用于计算每个排水区的人口。下诺基斯克次流域的2010年人口为46,204人，比2000年人口普查增加了8,345人。WRIA 1联合委员会工作人员团队同意采用每日人均88加仑的用水需求率，并与新的人口数据一起作为输入。同时，还确定了季节性需求系数，以分配月用水量，使得夏季用水需求达到峰值，而冬季则达到最低。

那些不由市政供应用水的商业和其他运营单位，要么由较小的公共供水系统提供服务，要么自行供水。对于上述市政服务区域之外的商业用户，其用水量是根据2003年与WRIA 1水量技术团队达成的平均用水率进行估算的。商业用水量基于惠康县评估员记录中确定的运营类型。
