In 1999, the National Association of Clean Water Agencies (NACWA)
(formerly the Association of Metropolitan Sewerage Agencies -- AMSA) and the
Water Environment Research Foundation (WERF) formed a partnership to fund
and develop a centralized Internet database containing detailed technical
and research information relevant to wastewater facilities. The intent
was to build a fully searchable database providing public utility managers
and researchers access to a range of valuable information on treatment
processes, collection systems, and equipment used at agencies and facilities
within the NACWA and WERF memberships. Queries on these data would help
NACWA and WERF identify trends, forecast research needs for the future,
and assist in targeted regulatory and legislative efforts. In addition,
the database is also designed to ease the gathering of technical and research
data via the use of online surveys. This database has become known as
Cleanwater Central™.
Current Database Contents
Currently, the Cleanwater Central™ database
contains data on over 525 wastewater agencies and 800 treatment facilities
nationwide.
The information includes data collected from NACWA surveys, WERF research
studies, and utility and facility data provided public water and wastewater
agencies. Several of these surveys were designed to provide only aggregate
information. In these cases, data have been blinded (not linked to individual
agencies) and are available in summary formats only. Current data includes:
- NACWA and WERF Membership Information 2010
- WERF Flushables and Screening Devices Survey 2010
- NACWA Index (Household User Charges) 1985-2009 (Blinded)
- NACWA Peak Performance Awards 1998-2009 (Blinded)
- NACWA Financial Surveys 1996-2008
- NACWA Public Relations Survey 2006
- WERF Inspection of Ferrous Force Mains 2005
- WERF Plant Upset and Detection Methods 2005
- AMSA/WERF THC/CO CEMS Survey 2004
- AMSA Sewage Sludge Survey 1996 (Blinded)
Data Updates and Surveys
Each year, public agencies subscribing to Cleanwater Central™ are asked to update
their baseline agency and facility level information online. In this manner,
redundant collection of agency and facility description data is minimized,
while ensuring that the
database remains up-to-date. Cleanwater Central™ will also be used
to centralize information gathered in future NACWA and WERF surveys, and includes
an online survey collection/viewing tool.
Queries and Reports
Cleanwater Central™ includes a powerful
data analysis and querying tool for those seeking specific agency
or facility-level information, data from past utility surveys, or
utility benchmarking data. Cleanwater
Central subscribers can query on several different parameters and
summarize data
via charts
and
graphs,
and
statistical summaries. Downloads of data in Microsoft Excel format
are also available. Following a few simple steps, a user
can build his/her own queries and output various statistics or
performance indicators
based
on the data contained in the database.
Access to Cleanwater Central™
Access to the Cleanwater Central™ database is restricted. Public affiliates,
public members, and public subscribers of NACWA and WERF have been provided
with free access to the database. Public agencies not affiliated with NACWA
and WERF can also gain free access by adding their agency and facility information
to the database. Private entities may pay for access, however, information
will be available in a blinded format only. For more
