          Mile Beach. The original facility consisted of four, large,
        
        
          waste stabilization ponds. “But since 2005, we have a
        
        
          Sequencing Batch Reactor plant with a capacity of 2.5
        
        
          million gallons a day, and that’s actually the first phase
        
        
          out of four; it’s designed to ultimately treat 10 million
        
        
          gallons a day,” van Zanten states. “So, hopefully, in the
        
        
          future, we’ll expand our collection system. Our man-
        
        
          date dictates that we’ll have to do that. But it’s going
        
        
          to be a gradual process.”
        
        
          Other items on the Authority’s immediate and ongo-
        
        
          ing agenda include a new water distribution pump sta-
        
        
          tion in George Town equipped with variable frequency
        
        
          drives that adjust the speed of the pump motor to fit
        
        
          the water demand at any given time, thus saving ener-
        
        
          gy and money; the installation of bulk water meters at
        
        
          strategic places, where the net inflow of water can be
        
        
          compared against water sales; and the replacement
        
        
          of older water meters to ensure that all water used by
        
        
          customers can be properly and accurately registered.
        
        
          “The next step would be to go to smart meters,” says
        
        
          van Zanten. AMI (Advanced Metering Infrastructure)
        
        
          uses wireless water meters that send data on water
        
        
          use from each customer to a central monitoring loca-
        
        
          tion. “The system is capable of logging the water us-
        
        
          age and alerting the Water Authority if a customer has
        
        
          a sudden or unusual spike in water usage (either in
        
        
          real time or using historical data, in the event of a cus-
        
        
          tomer dispute), or if there are localized low pressure
        
        
          areas, which are possible indicators of a leak.
        
        
          This could help the Water Authority identify the loca-
        
        
          tion of pipe breaks, allowing for quicker repairs and
        
        
          less lost water,” say van Zanten. “It will give us a lot
        
        
          more data, our customers can see their own usage to
        
        
          see if there’s anything amiss, and we can do the same
        
        
          thing. Plus, our staff won’t have to go out and operate
        
        
          a valve.”
