The development of municipal sewer system as well as constructing its 20 km concrete piping transmission line to the waste water treatment plant has been under construction. The treatment plant has been designed for a population of 1.5 million people and its contract has been awarded to a general contractor. The owner, Isfahan Water and Waste Water Company, requested a value-engineering consultant to review the project in order to reduce the cost of the project while improving the quality of the design. This paper explains the procedure of value analysis that was performed by the consultant. Value engineering of the project resulted the improving of quality in design and also reducing the cost of project by 250,000 dollars. Thus, the return of investment of value analysis study is estimated to be about 50:1 which implies that for spending one dollar for value analysis the saving in the project’s cost is 50 dollar.
