Please read about the new report released today by NFPA. This new report dispels the "water issues" argument and is a must read. An excerpt from the NFPA press release follows:
New study shows ease of integrating home fire sprinklers with local water supply systems
No design issues or significant cost issues found
October 22, 2009 – Home fire sprinklers can be integrated with local water supply systems with ease according to a new study - Integration of Residential Sprinklers with Water Supply Systems(PDF, 842 KB) - released today by the National Fire Protection Association (NFPA). The study, conducted by Newport Partners of Maryland, looked at detailed information for 20 US communities with a residential sprinkler ordinance and concluded that water supply integration requirements have been put into place, and there are no examples of insurmountable problems or issues. Neither design problems nor significant added costs were found in the communities surveyed.
“This is another critical piece of substantiation against the myths that abound about home fire sprinklers,” said Jim Shannon, NFPA president. “It is simply not true that sprinklers cannot be integrated with public water supply or significantly adds to cost. What is true is that home fire sprinklers save lives and should be required in new construction of one- and two-family homes.”
Key findings from the report
While sprinklers are still a fairly recent development in all of these communities (average ordinance age is about 3 years), water supply integration requirements have been put into place, and there are no examples of insurmountable problems or issues. Neither design problems nor significant added costs were found in the communities surveyed. Findings included:
- Nearby communities, such as those in the same state, generally adopt consistent provisions on issues such as water metering requirements; making compliance more uniform and predictable.
- More unusual design requirements, such as dual water service lines or dual water meters, are rare and typically driven by a local issue which would not apply in most other areas
- In more than half of the communities, no cost impact resulted from sprinkler-induced changes to water meter size, the need for additional water meters, or changes to tap size. These communities also did not have higher monthly service fees from the water supplier for homes with sprinklers. (In those communities where one or more of these factors did add cost, the average added cost was about $400.)
- Administrative issues such as concerns about water shut-off and larger, less accurate meters are not viewed as significant issues. In those communities where system inspections are required, communities are adopting a variety of practical strategies.
Overall, water suppliers, building departments and fire service have developed practical approaches to accommodate both home fire sprinklers and the local water supply.
In-depth interviews were conducted with 20 U.S. communities with a residential sprinkler ordinance to better understand how sprinklers are integrated with the local water supply systems, including any added costs related to meters or tap fees. Participants included local water providers, building departments and fire service staff. The interview questions were based on a literature review of fire sprinkler/water supply integration issues, and were conducted by phone after first screening a community to make sure it had an ordinance covering all new single-family construction that had been in effect subsequent to 1999. This research was conducted in Spring/Summer 2009.
This new tool in the arsenal is an important one as we continue to dispel the myths associated with the adoption of the one- and two-family home fire sprinkler requirement.
