One 
  of the most important services to any site, whether industrial or residential, 
  is water, and accurate selection that considers all the factors involved, is 
  critical. More stringent water regulations are now precluding direct connection 
  to the mains water supply. The resulting need for holding tanks therefore kills 
  the pressure previously afforded by the main and booster sets are required to 
  restore the pressure required. 
Whether 
  the requirement is for single or multi-pump, constant or variable pressure or 
  energy saving variable speed drives, AJH can help with assessing the most suitable 
  equipment.
