Chapter 6 Standard for Fire Flow for Fire Protection
1.0 General.
1.1 Purpose. The purpose of this Chapter is to specify minimum requirements for water supplies for fire protection and fire fighting services (fire flow) that will provide a reasonable degree of protection to life and property from fire.
1.2 Intent. It is the intent of this Chapter that the State Fire Marshal, the fire department having jurisdiction, the land developers in the jurisdiction, and any other responsible agencies shall work together to provide and maintain the minimum fire flow requirements contained herein.
1.3 Scope. This Chapter establishes minimum requirements for water supplies for fire protection and fire fighting purposes. This Chapter also sets the requirements in rural areas where there is no public, private or central water system available from water companies. The requirements are performance oriented and allow the owner or developer the option of choosing the method of attaining the water supply required with consideration given to local conditions.
1.4 This Regulation does not apply to:
1.4.1 Residential sub-divisions, located with the jurisdiction of New Castle County, containing more than twenty-five (25) lots, or minimum aggregate side yard widths of less than thirty (30) feet. These requirements are contained in New Castle County Code Chapter 40, Article 12.
Note: New Castle County Code Chapter 40, Article 12, Sewer and Water Impact:
1.4.2 Fire hydrants, located within the jurisdiction of New Castle County. These requirements are contained in New Castle County Code, Chapter 40, Article 22.
Note: New Castle County Code Chapter 40 Article 22, Drainage, Utilities, Septic Systems, Parking, Loading, and Lighting:
2.0 Application.
2.1 Notwithstanding, any other provisions of the Delaware State Fire Prevention Regulations, for all buildings or structures of less than 10,000 square feet of aggregate gross floor area, and where there is not a public water system or a central water system; the State Fire Marshal may utilize the provisions of the Standard on Water Supplies for Suburban and Rural Fire Fighting, NFPA 1142, as adopted and/or modified by these Regulations, as meeting the requirement for fire flow. (See §7.0, Dry Hydrants, at the end of this Chapter).
2.2 A building, structure or the use of a parcel of land shall not be constructed, extended, renovated, or altered in violation of this Chapter. All provisions of this Chapter shall be met prior to the existence of the exposure or hazard unless arrangements can be made to phase the installation of the fire protection, which is acceptable to the State Fire Marshal, and would not impair the intent of this Chapter.
2.3 This Chapter applies wherein the construction, renovation, or alteration constitutes a hazard or condition which could create a self-propagating fire exposing an existing structure, fuel load, or property line that could be built upon. In the event there is no existing adjacent structure, the location of the property line shall govern.
2.4 This Chapter applies to all occupancies including one- and two-family dwellings, any hazardous processes, and the handling, storing, or use of flammable and combustible liquids and flammable gases.
Note: Any flammable and combustible liquid and gas site that falls within the scope of a specific NFPA code, as adopted and/or modified by these Regulations, shall be subject to additional requirements, for water supplies, including, but not limited to, the following:
Exception: This Chapter does not apply to four (4) or less one- and two-family dwellings when the four (4) one- and two-family dwellings, considered as a group or one fuel station, do not create an exposure to any other structure, fuel station or property line that could be built upon.
Note: Exception: It is the intent of this exception not to require water distribution systems when four or less single family detached dwellings are constructed in close proximity to each other (less than 100 feet). It is not the intent of this exception to allow or condone the construction of multiple groups of four (4) or less single family detached dwelling units wherein the arrangement of those groups constitutes a configuration that, in the opinion of the State Fire Marshal, would support a self propagating fire from one fuel station to the next.
2.5 The owner or his representative shall submit adequate plans of any construction, renovation, alteration or the use of a parcel of land prior to any work being performed and obtain written approval from the State Fire Marshal. The plans shall display all necessary information and calculations in accordance with this Regulation. At the completion of construction and prior to occupancy or functional use, the owner or his representative shall supply to the State Fire Marshal a report verifying the following:
2.5.1 That the actual exposure distances on the site as constructed are within the allowable limits of this Regulation and the approved plans;
2.5.2 That the required fire flow was obtained and verified by on site flow testing, at the required minimum residual pressure;
2.5.3 That the hydrant spacing, location and arrangement is in accordance with this Regulation and the plan approval, and;
2.5.4 That the required minimum duration of flow, as required by this Regulation and the plan approval, is obtainable as verified by field calculations of the storage facilities.
Exception to §2.5.4: When an unproven well (new well or a well that has been out of service for more than six months) is used as a water supply source, the owner may meet the requirements by one of the following methods:
1. Obtain certification from a recognized authority that the well is capable of providing the minimum
required fire flow for the minimum required duration.
OR
2. Provide flow test results verifying that the unproven well was tested and provided the required
minimum fire flow for the required minimum duration.

Fire Flow Table 1*
The requirements of Fire Flow Table 1 apply to rural areas where public, private, or central water is not available and where specified elsewhere in these Regulations.
1 A fire alarm signaling system shall be provided. See §3.1.4.
*A-Fire Flow Table 1.
The requirements of Fire Flow Table 1 apply to rural areas where public, private or central water is not available. Where Exposure Hazard, Same Property (EHSP) or Minimum Set Back from all property lines (MSB) cannot be met, the following table may be utilized.
Fire Flow Table 2
 
The requirements of Fire Flow Table 2 apply to areas where there is a public, private, or central water system.
Rowhouses1 & Townhouses1
1Sites in New Castle County are subject to the provisions of New Castle County Code Chapter 40 Article 5. See Note on §1.4.1 and §1.4.2.
Note: Fire Flow Table 2, Hydrant Spacing. The phrase, “on center” is intended to represent the maximum distance fire hydrants are spaced from each other. Proper application of this intention would generally provide a fire department with a maximum “hose lay” to a hydrant that would not exceed 500 feet for One & Two Family Dwellings, and 400 feet for all other structures.
 
Fire Flow Table 3
It is the intent of Fire Flow Table 3 to allow a credit for water flow that is available on site, but does not meet the full water flow requirements of Fire Flow Table 2. However, the available water flow on site shall be a minimum of 500 GPM, otherwise the requirements of Fire Flow Table 1 shall be applied to the site. This Table does not apply to new public, private, nor central water systems, including municipalities.
 
Note: Fire Flow Table 3: For example, if 1,000 GPM is required for a 9,000 sq. ft. Business Occupancy, but only 500 GPM is available, or 50%, then the required setbacks shall be reduced by 50% so that the Minimum Setback (MSB) from property lines would be 7.5 feet, instead of 15 feet, and the Exposure Hazard on the Same Property (EHSP) would be five feet, instead of ten feet.
