  Water systems

  A facility may have several water systems, some for process use (process coolingwater, chilled water) and some for building services (potable water, domestic hotwater).Whatever their function; water systems tend to have similar inefficienciesand energy management opportunities.Water losses are detailed in the following Table.

  Default table type

  Leakage	Daily Loss	Monthly Loss	Yearly Loss
  One drop/second	4 L	129 L	1.6 m3
  Two drop/second	14 L	378 L	4.9 m3
  Drops into stream	91 L	2.6 m3	31.8 m3
  1.6 mm stream	318 L	9.4 m3	113.5 m3
  3.2 mm stream	984 L	29.5 m3	354.0 m3
  4.8 mm stream	1.6 m3	48.3 m3	580.0 m3
  6.4 mm stream	1.6 m3	105.0 m3	1260.0 m3

  Knowing the local rates, you can calculate the unnecessary costs above. Chances are that there may be several leaks in a plant at the same time.

Our group can serve the following activities:

1. Detecting and eliminating leaks.
2. Examining water use patterns and reducing water consumption to the minimum necessary.
3. Imaginative re-use and recirculation of process and cooling waters.
4. Reduction of friction losses and the associated pressure drops.
5. Reduction of heat loss from hot water systems and heat gain to chilled watersystem.
6. Correct choice and sizing of pumps and reduction of pump operating time.
