Project Proposal

Reservoir Dredging and Its benefits to Society

• Dredging introduction
• Benefits of dredging
• Drought condition in Maharastra
• Dredging in reservoir
• Benefits of dredging in Reservoirs
• Methodology and Implementation
• Feasible methods
• Calculation and estimation

Dredging- Introduction

• Underwater excavation or scooping out, weeds & rubbish with a dredge/dredger/pump
• Helps to increase capacities of water bodies, helps in navigation
• Done with professional assistance and equipment
• Equipment includes pumps dredging vessels and pipelines barges- depends upon method of disposal

Benefits of Dredging

• Helps gathering sediments- unwanted wastes and debris
• Widening and deepening of water bodies
• Increases reserve storage capacities of water bodies
• Creates ant sludge pathways for navigation
• Replenish sand for coastal development as a remedy to coastal erosions
• Reclaim land to generate islands for land accumulation
• Increase capacities of freshwater bodies

Drought Condition in North India

• 2010 drought in North India unlike 80 years
• 390500 villages in North India are prone to droughts again
• Crops and other utilities are getting severely effected by these conditions
• As a consequence water storage is required to be increased
• The reservoirs are required to be dredged to increase the capacity in terms of water storage

Dredging in Reservoirs

• Controlling the sediment balance sustainably (low turbidity)
• Using the existing reservoir, no new constructions needed
• Efficient use of water
• Controlled reservoir management

Benefits of Dredging In Reservoirs

• Other than increasing capacities in reservoirs:
• Important issue is the relocation of the sedimented material
• Most reservoirs are located in mountainous area’s
• Possible re-use depends on properties, soil types and local needs
• Create land (fertile soil can be used to create land within the reservoir or region)
• Re-use of sand (for example to create building material)
• Bring back sediment in to the river to restore the natural sand balance
• Helps in creating a land where water parks can be build, for boating and water sports, which can further bring tourist attraction.

Methodology & Implementation

• Assigning a Portable Conventional Cutter Suction dredger
• Using TT/toyo/Bell pumps in case of loose/cohesive soils
• Potable crawl cat/water master dredger
• Portable IHC crawler with the help of geotextiles and geotubes to avoid problems further
• In line helping the reservoir sediments to vacate and increase reserve capacities

Feasible Method

• Compact submergible dredge pump
• Equipped with jet nozzles to boost production
• Widely applicable (pontoon, crane etc.)
• Depth > 50m
• Highly wear-resistant
• Supported by an economical crawler for mobilisation
