PW-1 @ WELL #1

SUBMERSIBLE PUMP & MOTOR WATER SUPPLY/ TREATMENT P&ID 1

As per Ten State Standards, Section 7.2.2a, the capacity of the well and pump in a hydro-pneumatic system should be at least ten times the average daily consumption rate. Using an average 3,100 gpd for building use the capacity of the well and pump would be 31,000 gpd. Using a typical 8-hr work day, the maximum flow capacity of the well and pump would be 65 gpm (31,000 gpd/8 hr-day/60 minutes). Due to fire flow requirements a maximum flow rate of 157 gpm is required (see fire flow design). It has been assumed that the well is capable of pumping the fire flow rate. For design of the building potable water treatment system a maximum flow rate of 65 gpm will be used.

Type

SODIUM HYPOCHLORITE SYSTEM DESIGN CALCULATIONS:

SODIUM HYPOCHLORITE (12.5%)

Chlorine Residual in Hydro-Pneumatic Tank= 2 ppm

1. Hypochlorite Feed Tank Design

Average= 6.5 gpm (3100 GPD/8-hr day)

(6.5 gallon/minute x 480 minute/day x 2 ppm / 0.125) / 1,000,000 = 0.050 gallon/day

Maximum = 65 gpm (31200 GPD/8-hr day)

(65 gallon/minute x 480 minute/day x 2 ppm/ 0.125) / 1,000,000 = 0.50 gallon/day

SCALE: NO SCALE

REFER TO P-101, DETAIL 2

FOR MECHANICAL ROOM EQUIPMENT LAYOUT

At average feed rate of 0.05 gpd a 5 gallon carboy would supply hypochlorite for 100 working days. At average feed rate of 0.5 gpd a 5 gallon carboy would supply hypochlorite for 10 working days. It will be assumed that the 1908 facility will not be using 31 ,200 gpd of water for typical building usage. For a 30-day supply of sodium hypochlorite a 5 gallon carboy could supply 0.17 gpd of chemical which would be sufficient to treat 10,560 gpd of water (3.4 times the average daily usage). Therefore, Sodium Hypochlorite tank can be a 5 gallon carboy.

2. Hvpochlorite Pump Design (based on max 65 gpm)

(65 gallon/minute X 480 minute/day X 2 ppm / 0.125) / 1,000,000 = 0.50 gallon/day = 0.06 gallon/hour (gph)

Pump shall be a Blue-White Industries Model A1NOOV-6T-O FlexFlo Peristaltic Metering Pump. 14 RPM, 115V, 60 Hz, digital speed control with external input and a capacity of 0.29 gph@ 100%. Pump shall be supplied with Tube No. 6, 1/4" ID x 3/8" OD Norprene

As per Ten State Standards, Section 7 .2.2b, the gross volume of hydro-pneumatic tank storage shall be ten times the capacity of the largest pump. Using a 65 gpm design pump capacity the gross volume of the tank shall be 650 gallons. A John Wood Company JBPR Series ASME Bladder type Hydro-Pneumatic Tank with 660 gallon capacity has been chosen. The tank will be operated between 35-75 psig.

Using 65 gpm (max. treatment plant capacity) as a basis of design, the total system head loss is 157 psi (362 ft). This is calculated using an estimated 132 ft static head (estimated drawdown depth to water of 120 ft deep plus 12 feet to top of pipe) plus 185 ft (80 psi) max tank pressure plus 45 ft in pipe losses.

o Pump Chosen: Goulds L-Series Submersible 6" Pump Model 120L 15 with 15HP, 460V, 3 ph, 60 Hz, 3600 RPM CentriPro Motor.

Based on the pump curve the pump is capable of 73 gpm at 419 ft TDH at 57% efficiency.

For the purposes of determining whether the pump chosen is sufficient for fire flow a second set of calculations were completed.

Using 160 gpm as a basis of design, the total system head loss in the firewater system is 85 psi (196 ft). This is calculated using an estimated 159 ft static head (estimated drawdown depth to water of 120 ft deep plus 39 feet to top of pipe) plus 37 ft in pipe losses.

o Pump Chosen is okay for fire flow: Goulds L-Series Submersible 6" Pump Model 120L 15 with 15HP, 460V, 3 ph, 60 Hz, 3600 RPM CentriPro Motor. Based on the pump curve the pump is capable of 164 gpm at 202 ft TDH at 52% efficiency.

DESIGN AND CONSTRUCTION NOTES:

The following notes are taken from the 2009 Edition of Ten States Standard and have been modified to fit the intent of this system Title headings are included for reference.

2.0 GENERAL DESIGN CONSIDERATIONS

2.10 SAMPLETAPS

Sample taps shall be provided so that water samples can be obtained from each water source and from appropriate locations in each unit operation of treatment, and from the finished water. Taps shall be consistent with sampling needs and shall not be of the petcock type. Taps used for obtaining samples for bacteriological analysis shall be of the smooth-nosed type without interior or exterior threads, shall not be of the mixing type, and shall not have a screen, aerator, or other such appurtenance.

2.15 DISINFECTION

All wells, pipes. tanks, and equipment which can convey or store potable water shall be disinfected in accordance with current AWWA procedures.

7.0 FINISHED WATER STORAGE

7.0.18 Disinfection

a. Finished water storage structures shall be disinfected in accordance with AWWA Standard C652. Two or more successive sets of samples, taken at 24_hour intervals, shall indicate microbiologically satisfactory water before the facility is placed into operation.

b. Disposal of heavily chlorinated water from the tank disinfection process shall be in accordance with the requirements of the state regulatory agency.

c. The disinfection procedure specified in AWWA Standard C652 chlorination method 3, section 4.3 which allows use of the highly chlorinated water held in the storage tank for disinfection purposes, is not recommended. The chlorinated water may contain various disinfection by-products which should be kept out of the distribution system.

If this procedure is used, it is recommended that the initial heavily chlorinated water be properly disposed.

7.3 DISTRIBUTION SYSTEM STORAGE

7 .3.1 Pressures

The maximum variation between high and low levels in storage structures providing pressure to a distribution system should not exceed 30 feet.

The minimum working pressure in the distribution system should be 35 psi (240 kPa) and the normal working pressure should be approximately 60 to 80 psi (410 - 550 kPa). When static pressures exceed 100 psi (690 kPa). pressure reducing devices shall be provided on mains or as part of the meter setting on individual service lines in the distribution system.

7.3.2 Drainage

Finished water storage structures which provide pressure directly to the distribution system shall be designed so they can be isolated from the distribution system and drained for cleaning or maintenance without causing a loss of pressure in the distribution system. The storage structure drain shall discharge to the ground surface with no direct connection to a sewer or storm drain.

8.6 VALVE, METER AND BLOW-OFF CHAMBERS

Wherever possible, chambers, pits or manholes containing valves, blow_offs, meters, or other such appurtenances to a distribution system, shall not be located in areas subject to flooding or in areas of high groundwater. Such chambers or pits should drain to the ground surface, or to absorption pits underground. The chambers. pits and manholes shall not connect directly to any stonn drain or sanitary sewer. Blow_offs shall not connect directly to any storm drain or sanitary sewer.

8.7 INSTALLATION OF WATER MAINS

8.7.1 Standards

Specifications shall incorporate the provisions of the AWWA standards and/or manufacture~s recommended installation procedures.

8.7.2 Bedding

A continuous and uniform bedding shall be provided in the trench for all buried pipe. Backfill material shall be tamped in layers around the pipe and to a sufficient height above the pipe to adequately support and protect the pipe. Stones found in the trench shall be removed for a depth of at least six inches below the bottom of the pipe.

8.7.3 Cover

Water mains shall be covered with sufficient earth (min. 3'-0" cover) or other insulation to prevent freezing.

8.7.4 Blocking

All tees, bends, plugs and hydrants shall be provided with concrete reaction blocking, tie rods or joints designed to prevent movement.

8.7.5 Anchoring of fusible pipe

Additional restraint may be necessary on fusible pipe at the connection to appurtenances or transitions to different pipe materials to prevent separation of joints. The restraint may be provided in the form of an anchor ring encased in concrete or other methods as approved by the reviewing authority.

8.7.6 Pressure and leakage testing

Installed pipe shall be pressure tested and leakage tested in accordance with the appropriate AWWA Standards.

8.7.7 Disinfection

New, cleaned and repaired water mains shall be disinfected in accordance with AWWA Standard C651 . The specifications shall include detailed procedures for the adequate flushing, disinfection, and microbiological testing of all water mains. In an emergency or unusual situation, the disinfection procedure shall be discussed with the reviewing authority.
