Page 2 of 12 Aquifer Storage and Recovery Well # I and #2 Controls Upgrade December 13,2006 CITY OF BOYNTON BEACH TASK ORDER NO. - U.07-002 Control Description for the operation of ASR Well #'s 1 & 2 , Backaround , , I The City of Boynton Beach operates an Aquifer Storage and Recovery System (ASR) at its East Water Treatment Plant (EWTP) location. The system originally comprised a single well (ASR 1) which was used for both recharge and recovery. A second well was drilled in 2006 to allow for expansion of the ASR system. ! In principle treated water is stored in an underground tightly enclosed aquifer I beneath the EWTP. Water is pumped into the aquifer during the wet season of , May through November and recovered during the dry season of December through April. The water needs no further treatment although it is passed back through the filters to remove any sand that may have been entrained in the recovery stream. I General Principles , I Each well will be provided with similar control equipment (wherever possible) and' I will employ a similar joint control strategy. I Both wells will be run by either an existing PLC # XX stationed by MCC 1, or a new one of type to be determined, and viewed through either the existing Fix32 HMI SCADA system or through the proposed single utilities SCADA. " , I As far as possible the recharge and reclaim rates for each well will be equal and simultaneous. If only one well is used then we must attempt to balance the system over time. The wells will be equipped with vertical turbine pumps with VFD drives. Until there is a properly annotated copy of the ASR1 P&ID all references to the ASR 2 equipment names are to be assumed to be matched on ASR 1.

I : I I DCR Engineering Services, Inc. , Page 3 of 12 I Aquifer Storage and Recovery Well # 1 and #2 Controls Upgrade December 13,2006 ASR Recharae Recharge is achieved by using the existing system pressure as delivered by the high service pumps at the EWTP. There is no separate pumping system (Pump P-2-1 and Pressure Transducer PIT-2-2 as per drawing 1-2 are not required We need to move PIT-2-2 after FCV-2-1 so that we can measure the pressure at the wellhead during recharge.). Recharge Start-up will be as follows:- I Operator will select either ASR1, ASR2 or both for recharge. i Operator will enter a recharge rate. I Operator will confirm start parameters. I (If two wells are chosen - which will be normal operation - the flow will automatically be distributed evenly) The standby valve FV-2-2 will be closed. i The flow control valves will be closed. System will slowly open the control valves by increasing the set-point from zero with a ramp of 100 gpm2 until desired set point value is met. Flow to the aquifer will now be control by a feed-forward loop from the flow transmitter FE- 2-1. I While in recharge mode the system will monitor the high service pressure. If this I pressure falls below 50 psig the system will perform a controlled shutdown (see , below). If the high service pressure fails below 45 psig or the operating high' I ! service pumps fail the system will perform an emergency stop (see below). The I recharge system will not restart automatically if the fault condition is corrected, I but must go through a normal restart only when initiated by an operator. I I I To change flow when in operation the operator will request to change the flow , and then enter a new value. Upon confirmation of the new rate the system will I ramp the set point up or down at a rate of 100 gpm2. I I, Recharge Shutdown will be as follows:- I I Operator will enter a shutdown request. Upon confirmation the system will progressively reduce the set point of the flow controller at a rate of 100 gpm2 until it reaches zero. When the set point reaches zero the main supply valve will close. This proposal contains intellectual propelty of D!<R Engineering Services, Inc.

Page 4 of 12 I Aquifer Storage and Recovery Well # I and #2 Controls Upgrade December 13, 2006 Emergency Stop - The operator will have the option to initiate an emergency stop if required. In this case both the main supply valve and the flow control valve will be driven to zero. After 10 minutes if recharge has not been restarted by the operator the system will automatically revert to stand-by mode. ASR Standby When either ASR well is in standby condition, that is neither recharging nor reclaiming, it is necessary to keep the well free of potential bacterial problems. This is achieved by using a small 1 inch by-pass line fitted with a :y. inch automated valve FV-2-2 and water meter FE-2-2. When the system has been shutdown the automated valve is opened to allow a small flow of chlorinated water down the well. The valve is closed whenever normal recharge or reclaim operations are underway. The system will totalize the additional water added to the system during standby. I ASR Recovery , Recovery is achieved using the well pumps. These pumps have a variable speed I drive which is the main control device. Each system also has a flow measurement device and a conductivity probe to monitor saline levels. There is , also a diversion system for use during routine start-up to allow for water clarity to , be settled before sending forward to the plant. The normal operating range for , the reclaim pumps is 500-1500 gpm. Reclaim Start-up is as follows:- Operator will select either ASR 1, ASR2 or both for reclaim. Operator will enter a reclaim rate. Operator will confirm start parameters. (If two wells are chosen - which will be normal operation - the flow will ! automatically be distributed evenly) The standby valve FV-2-2 will be closed. I I The main recovery valve (FV-1-1 on 1-2) will be set to open. The valve (FV-1-2 on 1-2) to the WTP will be set to close. I The valve (FV-1-3 on 1-2) to the storm water (or reclaim) pond will be set to open. I I Pump P-1-1 will be started and driven to maximum output as soon as practicable. ! I The pump will operate at maximum for a period of 5 minutes and then flow will be ! ramped down at a rate of 100 gpm2 until it reaches the set point.

Page 5 of 12 Aquifer Storage and Recovery Well # I and #2 Controls Upgrade December 13,2006 After a further 5 minutes at this rate, or after 15 minutes (whichever is the greater), the system will change over to production as follows:- The valve to the water treatment plant (FV-1-2) will open. The valve to the pond (basin) (FV-1-3) will then be closed. The set point for flow control will remain at the desired flow rate. Any subsequent changes in flow inputted by the operator will be made at 50 gpm2, (Supervisory access should be given to enable a change to this ramp factor) Periodic system flush during routine reclaim. After an extended period of operation it will become necessary to "clear the baffles" of any sand build up. This is accomplished by briefly increasing each pump independently (and at differing times) to maximum flow for a period of 5 minutes. A timer will be set at the start of normal operation and after 24 hours will cause this operation to start. A separate timer will ensure that there is a minimum of 30 minutes between either ASR pump performing this task. There should also be provision for the operator to manually initiate this operation. There is no requirement to divert flow away from production when this operation occurs. Conductivity Measurement At any time during reclaim the conductivity meter will be monitored and recorded I by the system. During commissioning it will be calibrated to represent saline I , content of the reclaim water. If the conductivity (saline level) in the reclaim water' I exceeds a set level the system will immediately divert the flow to the basin (pond) , and start a shutdown. i I Well Level Measurement I The level in the well will be measured and recorded at all times. I If the well level falls to 15% of scale then a warning will be shown on the screen I by a flashing signal. I , If the well measurement fails or the level falls to zero (the low level is set above , , the pump) then the system will undergo an emergency stop. i !

I Page 6 of 12 I Aquifer Storage and Recovery Well # I and #2 Controls Upgrade I December 13,2006 Reclaim Shutdown is as follows:- If the operator initiates a reclaim shutdown (or the saline level exceeds it desired value) the system will start a controlled shutdown. The flow rate set point will be reduced at the rate of 50 gpm2 until it reaches 500 gpm. At this point the pump motor will be turned off and the main valve (FV-1-1 on 1-2) will close. The valve to the pond will remain open. Emergency shutdown will occur as follows:- I In the event of an emergency shutdown the valve to the pond will open and then the valve to the WTP closes. , The power to the reclaim pump motor will be shutoff. I The system will remain under artesian flow for 10 minutes to allow the motor to I cool and then the main valve (FV-1-1 on 1-2) will close. The valve to the pond will I remain open. , Whenever an Emergency stop is initiated the system will only restart if initiated by the operator through the standard procedure. Alarms Major alarms will be notified to the operator by means of a pop-up window detailing the issue. This window will remain on the front of the screen until I acknowledged. If there are several alarms because of the nature of the initial , problem, only the first (or originating fault) will be displayed as a pop-up. i I All alarms, both major and minor, will be recorded in the alarm database and I available for ongoing review. , I (For example: The well level indication has the Low Level alarm (Minor) and the I LoLo Level alarm (Major). The low level alarm will show up as a flashing warning on the graphic and be recorded in the database. The graphic will continue I flashing until the alarm condition ceases. The LoLo level alarm will as described I I cause an emergency stop. The pop-up window will show the condition as LoLo I and will not in this case because a second window to detail that there was an i emergency stop since that is implied by the originating call on the system.) , , I This proposal contains intellectual property of D!<R Engineering Services, Inc.
