The DJB officials were accused of conspiring with the contractor, who submitted false bills, to record false entries in the measurement books showing installation of pipes which were five to six times costlier than the ones actually used.
Special CBI Judge Manoj Jain ordered the re-probe rejecting CBI's closure report which said that no case was made out against the six public servants and a contractor for want of sufficient evidence as it was not possible to assess whether there was any pipe of the requisite brand or not after a particular depth.
While the contractor was required to install pipes of a particular company, he in connivance with DJB officials installed pipes of an ordinary brand and raised bills for the costlier brand.
The FIR was registered by CBI on the basis of information received from a source in September 2011 against officials of southwest division of DJB -- P K Jain, N K Khare, Shiv Hari, Birendra Singh, R B Sharma and Ashok Pal Panwar and a private contractor M/s R B Sales (India).
