Visual Tank Inspection

  • Safe access to the tank

  • Available lighting system works properly

  • Tank condition is considered good (no rusting, no signs of corrosion or pitting)

  • Outer tank surface check for any sign of leakage or excess flow or weakness in the flow

  • No signs of separation or swelling of tank or cracks at inside/outside surface of the tank

  • Bolts, rivets and/or seams are not damaged and appear in good condition

  • Valves, flanges and gaskets are free from leaks

  • Vents are not obstructed. Ventilation’s stopcock’s works properly.

  • Nearby tank any oil, chemical or sewage leak

  • Outer Surfaces of the tanks free from dirt & birds facial

  • Opening is uncovered / door is locked

  • No any sign of algal growth around the tank opening / manhole

  • No any accumulation of dirt around the tank

  • Door to tank is in good condition and seal

  • Level gauges and alarms are working properly (push button to test alarms)

  • location of the reservoir clean and away from sewage water at least or more than 10 m

  • What is the measured distance of reservoir from sewage water is (m)

  • Distribution/outlet water slots should be above or equal to 10 cm from the bottom of the tank.

  • Distance of the outlet water slots from the bottom of the tank is (cm)

  • The distance between the top surface of the tank and the water should not be less than 30 cm

  • The distance between the top surface of the tank and the water is (cm)

  • If the water tank mounted on pillars, then height from the floor should not be less than 20 cm

  • The height of water tank from the floor is (cm)

  • No signs of Sediment/ Sludge inside the tank

  • No signs of any algae growth inside the tank

  • No signs of any micro-film or oils inside the tank

  • Out of service pipelines are capped

  • Pumps valves free from rust, no signs of corrosion or pitting

  • Inside the water tanks Ladders made/installed of stainless and non-toxic materials

  • Water outlet openings excess water with a diameter greater than the feeding diameter or at the same level

  • Any sign of tank material like paint peels off from the inner surface which transferred from the tans body to the water

  • Does any change in the water colour, taste or odor etc
