Waste Water Lifting Point Lift Stations‚ or Pump Stations are known as the structure that are used to "lift" liquid uphill - against gravity. They are the essential component of a wastewater collection system which takes wastewater from residents and businesses in a community and pumps it to a sewage treatment plant. They are equally essential in moving "potable" water from a water treatment plant up to one or more reservoirs‚ so that clean water can flow by gravity to the community. Waste water

ABSTRACT The quality of pipe borne water supplied by Imo State Water Corporation has been assessed by analyzing samples of water collected from different locations for their physicochemical parameters and bacteriological quality. The observed values were compared with standard values given by the World Health Organization for potable water .The quality of the analyzed water is found fit for human consumption.
