DRAWING LIST

DESIGN PHILOSOPHYTO REPLACE THE EXISTING OUTFALL ARRANGEMENT THAT SEES TREATEDEFFLUENT FROM THE CARRICK WWTP DISCHARGED INTO AN OPENCHANNEL THAT CONVEYS THE FLOW TO THE LIFFEY RIVER WHICH,IN TURN DISCHARGES INTO THE MEANDER RIVER.THE PROPOSED ARRANGEMENT WILL ALLOW TREATED EFFLUENTTO BE USED FOR IRRIGATION PURPOSES ON THE FARMING PROPERTY"THE MOAT" AND EXCESS TO BE DISCHARGED TO THE MEANDER RIVER.

MODES OF OPERATIONTHE PROPOSED SCHEME WILL OPERATE UNDER A NUMBER OF SCENARIOS. THESEINCLUDE THE FOLLOWING MODES OF OPERATION:1. REUSE IRRIGATION - TREATED EFFLUENT TO IRRIGATION PUMP FOR USE BYPROPERTY OWNER FOR IRRIGATION.2. OUTFALL - TREATED EFFLUENT TO THE OUTFALL IN THE MEANDER RIVER.3. STORAGE - TREATED EFFLUENT TO FILL THE WWTP STORAGE LAGOON4. EMERGENCY - TREATED EFFLUENT TO OPEN CHANNELSYSTEM CONTROLS WILL PERMIT ONLY ONE MODE OF OPERATION AT A TIME.TREATED EFFLUENT STORAGE LAGOON ( TESL ) = 25MLWWTP AVERAGE DAILY FLOW ( THROUGHPUT ) = 0.5 TO 0.6ML / DAY ( 5.8 TO 6.9 L/S )ESTIMATED TIME TO FILL THE TESL FROM EMPTY = 50 DAYS TO 42 DAYSESTIMATED AVERAGE FLOW DELIVERED TO IRRIGATION PUMP = 42 L/SESTIMATED NETT EMPTYING RATE OF TESL = 36.2 TO 35.1 L/SESTIMATED TIME TO EMPTY THE TESL FROM FULL = 8 DAYS TO 8.2 DAYS
