Small systems (serving fewer than 10,000 people) still face difficulties in
meeting the requirements of the Safe Drinking Water Act (SDWA). Many technologies
available to large systems may not be suitable for small systems mainly because
they are prohibitively expensive due to the lack of economies of scale.
Furthermore, trained operators and maintenance personnel may not always be
affordable or available, which can lead to standards violations. As found in the
National Research Council study about small water systems, continuous technical
and financial assistance is still needed to help more than 54,000 small systems
comply with changing regulations. This study discusses some water treatment
technologies that small systems may use to provide safe drinking water to their
customers, who are mainly residential. The technologies discussed here surfaced
from responses to the questionnaire sent to thousands of small systems across the
nation. The information was compiled into the National Drinking Water
Clearinghouse (NDWC) Registry of Equipment Suppliers of Treatment Technologies
for Small Systems (RESULTS) database, which is a public reference database
containing information about technologies in use by small water systems around
the U.S. Includes 13 references, tables.
