The machine should have imported twin steel core protection rubber high pressure hose for safety, withstanding operating pressure of 250 bar, and two cleaning lances, one with rotary jet and the second one a flat jet for effective drinking water tank operation. STAGE – IV Vacuum Cleaning – Removal of remaining sludge from the floor with the help of industrial vacuum cleaner. (A) Removal of remaining sludge with the help of imported heavy duty industrial vacuum cleaner and sludge sucker having maximum power of 1200 watts, with suitable heavy duty motor. (B) Imported sludge sucker should be a part of the high pressure system which sucks sludge and throws the same out of the tank. This must handle solid particles as well. STAGE – V Anti-Bacterial Spray – Spraying of non-toxic, biodegradable, eco-friendly anti-bacterial agent to disinfect the tank from all harmful pathogens. The dose utilized should be safe as per WHO guidelines. STAGE – VI UV Radiator – Treatment of inside of tank by exposing UV radiator to kill further suspended or floating bacteria, if any. Treatment of inside tank should be done by exposing UV radiation by imported heavy duty UV radiator. The radiator should be designed in a way to ensure 360 degrees of sterilization and should have suitable lamps for effective sterilization for a period of 8000 working hours. The radiator must be totally portable and effective for final sterilization of drinking water tanks for elimination of floating and suspended bacteria. Notes:- i.
