( Litholog Assembly diagram must be approved by Engineer-in-Charge of the work prior to installation)

Shrouding of TW :- Shrouding of the Tube well assembly by packing of river Pea Gravel of size 4mm to 8 mm free from sand, dust and any other foreign materials after staking at site including screening, washing etc as per IS 4097/2008 along with transportation, labour etc. complete as directed and (Packing to done after lowering tube well assembly and also during development as reqd)

Developing the tube well assembly by Air-Compressor of capacity 8-12 kg/cm2 and CFM=450 M3/min so as to get sand free discharge of water with supply of all required materials at site complete as directed including furnishing of litho-log / draw down data etc. as per IS : 11185 of 1999. ( For new DTW minimum 72 hours development is compulsory. Additional pea gravel required if any, during development would be extra ) The following data should be reflected in the report of development 1. Static water level 2. Drawdown at various discharge 3. Available average discharge
