Sec. 2. (a) The calculated average and peak flowrate values required for a water main extension to a public water system shall be equal to the average and peak daily consumer demands of the proposed additional service connections calculated as follows:

(1) The public water supply quantity requirement for the average daily consumer demand for residential service connections shall be determined by using a general average daily demand value. The following method shall be used to calculate average and peak supply quantity requirements:

ADCD = (General Avg) × PRSC

PDCD = (ADCD × PF) + FF

Where:ADCD=Average daily consumer demand in gallons per residential service connection per day.
PDCD=Peak daily consumer demand in gallons per residential service connection per day.
General Avg=General average daily consumer demand value of five hundred (500) gallons per residential service connection per day.
PRSC=Proposed number of residential service connections.
PF=Peak daily consumer demand factor of two and one-half (2.5).
FF=Fire flow demand value equal to the fire protection flowrate provided by the public water system or zero (0) if the public water system is not providing fire protection.

(2) The public water supply quantity requirement for the average and peak daily consumer demand for residential service connections may be determined from the monthly reports of operations (MROs) as follows:

(A) The following method may be used to calculate average and peak supply quantity requirements for a public water system that has been in operation for at least ten (10) years and has an accurate record of MROs for that time period:

ADCD = (Max Average) × PRSC

PDCD = (ADCD × PF) + FF

Where:ADCD=Average daily consumer demand in gallons per residential service connection per day.
PDCD=Peak daily consumer demand in gallons per residential service connection per day.
Max Average=Maximum average daily consumer demand in gallons per service connection as calculated by:

Max Average = (ADCD10) ÷ (SC10)

Where:ADCD10=The highest average daily demand as reported on the MROs over the previous ten (10) year period.
SC100The number of service connections at ADCD10.
PRSC=Proposed number of residential service connections.
PF=Peak daily demand factor as calculated by the following:

PF = MDD10 ÷ 10YADD

Where:MDD100The maximum single day demand as reported on the MROs over the previous ten (10) year period.
10YADD=The ten (10) year average daily demand as calculated from the previous ten (10) year period.
FF=Fire flow demand value equal to the fire protection flowrate provided by the public water system or zero (0) if the public water system is not providing fire protection.

(B) If a public water service has not been in operation for at least ten (10) years, then all available MROs shall be used to determine the highest average daily demand (ADCD10), the number of service connections at ADCD10 (SC10), the maximum single day demand (MDD10), and the ten (10) year average daily demand (10YADD).

(3) The public water supply quantity requirement for the average and peak daily consumer demand for service connections described by Table 2-1 in subsection (b). The following method may be used to calculate the average and peak public water supply quantity requirements:

ADCD = DCF × PSC

PDCD = (ADCD × PF) + FF

Where:ADCD=Average daily consumer demand in gallons per service connection per day.
PDCD=Peak daily consumer demand in gallons per service connection per day.
DCF=Demand calculation factors as contained in Table 2-1 in subsection (b).
=Proposed number of service connections.
PF=Peak daily consumer demand factor of two and one-half (2.5).
FF=Fire flow demand value equal to the fire protection flowrate provided by the public water system or zero (0) if the public water system is not providing fire protection.

(4) If the average and peak daily consumer demand cannot be determined or calculated using the methods described in subdivision (1), (2), or (3), the determination of the average and peak daily consumer demand must be approved by the commissioner. The source and any calculations or assumptions must be approved by the commissioner.

(b) The following demand calculation factors shall be used in the calculations under subsection(a)(3):

Sec. 4. (a) All school buildings and related facilities must be supplied with safe, potable water from an approved source and water distribution system.

(b) The drinking water for school buildings and related facilities must be supplied at the flow rate and pressure required by 327 IAC 8-3.2-11, at the quality required by 327 IAC 8-2.7, and in accordance with the following:

(1) The water supply and water distribution system must be sized and constructed to deliver water at twenty (20) pounds per square inch minimum pressure to all fixtures and appurtenances during periods of peak water demand.

(2) Notwithstanding subdivision (1), school buildings may be served by hand-operated well pumps where religious custom precludes using electrically or gasoline driven well pumps providing the well and well pump are located and constructed in compliance with this rule.

(c) A connection to a PWS must be made with its potable water used exclusively wherever the system is available or becomes available within a reasonable distance from the school facility, with the exception that nonpotable sources of water are available and may be utilized for the following nonpotable activities:

(1) Lawn sprinkling.

(2) Bus washing.

(3) Firefighting.

(4) Other nonpotable uses provided by a nonpotable distribution system having no connection to the potable system.

(d) Where a community PWS is not available, a properly located and constructed private water supply must be provided. Beginning on May 1, 1999, all new and modified PWSs exclusively serving schools and related facilities must be equipped with a backup system capable of providing drinking water in accordance with subsection (b).

(e) Well pumps, pressure tanks, storage tanks, treatment facilities, and piping must be sized to meet peak daily consumer demands. The minimum usable capacity of the pressure tank, in gallons, must be three (3) times the installed well pump capacity in gallons per minute. If the well or pump cannot meet peak demands, sufficient additional usable storage capacity must be provided to meet peak demands.
