* The 'H1' data line contains Extran pump data (Max of 75).
*============================================================================
* H1 line :
* IPTYP : Type of pump.
* = 1 Off-line pump with wet well (program will
* set pump junction invert to -100).
* Pumping rate depends on volume in pumped junction.
* Pumping is constant between PRATE/VRATE points.
* Note: ONLY ONE CONDUIT CAN BE CONNECTED TO A
* TYPE 1 PUMP JUNCTION.
* Pump Rate - PRATE(1) for volumes less than VRATE(1)
* PRATE(2) for volumes less than VRATE(2)
* PRATE(3) for volumes greater than or
* equal to VRATE(2)
* = 2 In-line lift pump.
* Pumping rate depends on depth in pumped junction.
* Pumping is constant between PRATE/VRATE points.
* Pump Rate - PRATE(1) for depths less than VRATE(1)
* PRATE(2) for depths less than VRATE(2)
* PRATE(3) for depths greater than or
* equal to VRATE(2)
* = 3 Three-point head-discharge pump curve.
* Pumping rate depends on difference in head between
* discharge junction and pumped junction. Pumping
* rate varies linearly interpolated from entered
* PRATE/VRATE points.
* = 4 Variable speed in-line pump.
* Pumping rate depends on depth in pumped junction.
* Pumping rate varies linearly between input
* PRATE/VRATE points. Rate is constant at rate
* defined by first PRATE for depths less than VRATE(1).
* Rate is constant at rate defined by last PRATE for
* depths greater than last VRATE. PON and POFF are
* optional inputs. If entered, pump comes on when
* depth equals or exceeds PON and pump turns off when
* depth is less than POFF.
* = 5 Lift station type pump. This pump type was added to
* more realistically simulate the operation of typical
* pump stations. PRATE(1), PRATE(2), and PRATE(3)
* are individual pumping capacities of the installed
* pumps. Pump # 1 with capacity of PRATE(1) comes on
* at depth specified by VRATE(1) in the pumped
* junction and stays on until water levels in
* the pumped junction drop to POFF. Similarly,
* Pump # 2 with capacity of PRATE(2) comes on at
* depth specified by VRATE(2) and stays on until
* water levels drop to POFF.
* NJUNC(1) : Junction number being pumped, or
* junction name (enter in single quotes).
* NJUNC(2) : Pump discharge goes to this junction number, or
* junction name (enter in single quotes).
* Note, to pump to an outfall, pump to a junction
* designated on an I1 line.
* NRATES : Number of PRATE/VRATE Pairs.
* Enter this parameter only if optional parameter
* IPRATE on BB line is entered as a 1.
* By default, three PRATE/VRATE pairs are used.
* PRATE(1) : Lower pumping rate, ft3/s [m3/s].
* PRATE(2) : Mid-pumping rate, ft3/s [m3/s].
* PRATE(3) : High pumping rate, ft3/s [m3/s].
* Repeat the PRATE values NRATES times.
*
* Note PRATE does not necessarily have to increase
* but usually will. PRATE is the capacity of the
* individual pumps for type 5.
*
* VRATE values must increase for types 1, 2, and 4.
*
* VRATE values must decrease for type 3.
*
* VRATE(1) : If IPTYP = 1 enter the wet well volume for
* mid-rate pumps to start, ft3 [m3].
* If IPTYP = 2 enter the junction depth for
* mid-rate pumps to start, ft [m].
* If IPTYP = 3 enter the head difference (head at
* junction downstream of pump minus head at
* junction upstream of pump) associated with the
* lowest pumping rate, ft [m]. (This will be the
* highest head difference.)
* If IPTYP = 4 enter the pumped junction depth for
* which the pump rate equals PRATE(1). If depths
* are less than VRATE(1) rate equals PRATE(1).
* If IPTYP = 5 enter the depth at which pump #1 with
* capacity of PRATE(1) turns on.
* VRATE(2) : If IPTYP = 1 enter the wet well volume for
* high-rate pumps to start, ft3 [m3].
* If IPTYP = 2 enter the junction depth for
* high-rate pumps to start, ft [m].
* If IPTYP = 3 enter the head difference associated
* with the mid-pumping rate, ft [m].
* If IPTYP = 4 enter the pumped junction depth at
* which the pump rate equals PRATE(2). Pumping rate
* is linearly interpolated from PRATE/VRATE input
* points.
* IF IPTYP = 5 enter the depth at which pump #2 with
* capacity equal to PRATE(2) comes on.
*
* Note: A non-zero VRATE(I,3) and VWELL(I) are
* required only if IPTYP = 1, 3, or 4.
*
* VRATE(3) : If IPTYP = 1 enter total wet well capacity, ft3 [m3].
* If IPTYP = 3 then enter the head difference associated
* with highest pumping rate, ft [m]. (This will be
* the lowest head difference.)
* If IPTYP = 4 enter the pumped junction depth at
* which the pump rate equals PRATE(3).
* IF IPTYP = 5 enter the depth at which pump #3 with
* capacity equal to PRATE(3) comes on.
* Repeat VRATE NRATES times for IPTYP 1, 3, 4 or 5.
* Repeat VRATE NRATES minus 1 times for IPTYP = 2.
*
* Note: VWELL is required only for types 1 or 3.
*
* VWELL : If IPTYP = 1 then enter initial wet well volume,
* ft3 [m3].
* If IPTYP = 3 then enter the initial depth in the pump
* inflow junction, ft [m].
*
* Note: Enter PON(I) is required for IPTYP = 3
* PON(I) is optional for IPTYP = 4.
*
* PON : Depth in pump inflow junction to turn pump on, ft [m].
*
* Note: POFF(I) is required for IPTYP = 3, or 5.
* POFF(I) is optional for IPTYP = 4.
*
* POFF : Depth in pump inflow junction to turn pump off, ft [m].
*
* Note: Enter PONDELAY(I) for IPTYP = 5.
*
* PONDELAY : Time, seconds, required for pump rate for individual
* pumps to increase from zero to full capacity. Used to
* avoid shock produced by instantaneously turning pumps
* on at full capacity. Pump rates increase linearly from
* zero to PRATE over PONDELAY seconds.
