Method for manufacturing a system for treating reclaimed water to provide treated water

A method for converting an existing water treatment system to provide a flow of treated water having a pre-established quality from a flow of reclaimed water having a, quality poorer than said pre-established quality of said treated water and a flow of treatment water having a quality better than said pre-established quality of said treated water, said water qualities based on parameters including relative conductivity or TDS values wherein said existing water treatment system comprises:

• a mixing reservoir;
• first and second fluid conduits connected to said mixing reservoir for respectively flowing said reclaimed water and said treatment water into said mixing reservoir;
• and
• a third fluid conduit connected to said mixing reservoir for discharging a flow of treated water from said mixing reservoir;
• the method comprising the steps of:
• a. providing sensing means for sensing parameters including:
• (1) the flow rate and quality of the reclaimed water entering the mixing reservoir through said first fluid conduit, (2) the flow rate and quality of the treatment water entering the mixing reservoir through said second fluid conduit, and (3) the quality of the treated water being discharged from said mixing reservoir through said third fluid conduit, said sensing means including separate water conductivity measuring means installed in said first and second fluid conduits upstream of said mixing reservoir and in said third fluid conduit downstream of said mixing reservoir;
• b. providing signal generating means responsive to said separate conductivity measuring means for providing signals indicative of the TDS levels in said reclaimed water in said treatment water and in said treated water and indicative of said sensed water flow rates;
• and
• c. providing control means responsive to said provided signals for regulating the flows of reclaimed water and treatment water into said mixing reservoir through said first and second fluid conduits so as to cause the quality of the treated water discharged from said mixing reservoir through said third fluid conduit to be at least about as good as said pre-established treated water quality, said pre-established treated water quality including a pre-established maximum TDS level.
