Analysis
NAICS 2213 is the 2022 industry group for water, sewage and other systems, part of 221 (Utilities). Census lists 28 example activities under it in the official index.
County Business Patterns counts 5,210 US establishments in this code in 2023, employing 52,028 people at an average annual payroll of $77,927 per employee (66th percentile of national industries). 57% of the establishments have fewer than five employees, which is close to the national mix.
Across its national industries Census lists 28 index entries; typical ones are canal, irrigation, collection, treatment, and disposal of waste through a… and air-conditioning supply.
It splits into 3 more detailed codes. The largest by establishments is 22131 (Water Supply and Irrigation Systems) with 4,554.
Its more detailed codes are 22131 Water Supply and Irrigation Systems (4,554 establishments), 22132 Sewage Treatment Facilities (538 establishments) and 22133 Steam and Air-Conditioning Supply (118 establishments).
Between 2018 and 2023 the number of establishments grew 6% and employment rose 12%. The 2018 count used NAICS 2017, so part of a large move can come from codes being redefined rather than from businesses opening or closing.
