KW&SC seeks a specialized maintenance contractor for chlorination systems across 16 pumping stations—a 12-month recurring service contract worth ~PKR 14M.
This is infrastructure support work requiring technical depth in water treatment chemistry and equipment diagnostics, not construction. Bidders must field qualified staff at multiple sites simultaneously and meet stringent drinking water standards compliance. The scope includes emergency chlorine leak response, adding operational risk. Typical for utilities, this is a steady-revenue contract but demands PEC credentials, OEM certification or authorized agent status, and demonstrated chlorination expertise—screening out generalist contractors.
Who can bid: PEC Category C-6 or above (EE-02, EE-03, EE-04, ME-04, ME-06) mandatory. Must hold current FBR income tax and GST registration, Sindh Board of Revenue registration, and OEM or authorized agent or E&M maintenance expert certification. Minimum one similar project at 80% of estimated cost or two at 50%; three years documented chlorination/water treatment experience; five-year audit and three-year tax returns showing annual turnover ≥ estimated cost.
