Deep Borewell Method to Recharge Groundwater - Advice Required : Orissa

We are taking up construction work in 5 acres of land at Bhuvaneswar, Orissa.There is no outlet to discharge rainwater and we wish to use the entire rainwater collected in recharging the ground water. The soil nature is "murrum".We would like to discharge the rainwater in the ground water table.

I adviced that if we leave the water in underground water table by deep borewell method,there is chance of reverse flow due to negative pressure.

What methodology we need to follow so that entire rainwater get discharged in the under ground water table.How it is done scientifically so that there is no reverse flow and entire rainwater can be used in recharging the water table.

warm regards,




1. Discharge water into the groundwater system

Dear Mr Mallick

Disposal of water into the groundwater system is not a good proposal. It is like channelling your bathroom waste-water into your water-tank. In the process you may contaminate the entire precious natural resource of the area.

There is a clear difference between disposal and recharge, which should be understood.

Please think alternative.

Respected Dr PC Naik

My appology for not using appropriate terminology. I would correct myself stating that I would like to recharge the ground water table by using entire quantum rainfall on the plot.There is no other alternative available to me to channelise the rainwater anywhere else like storm water drain etc.

I ernerstly look for your advice in this regard.

Warm Regards.


3. Dear Mallick, You will be

Dear Mallick,

You will be able to discharge the entire rainwater falling within your premises only if the following conditions are satisfied.

1. The post-monsoon groundwater table should be low viz. at 10 ft. or more b.g.l.

2. The soil upto to 10 metres b.g.l. should be reasonably permeable viz. sandy, silty or gravelly. Even murram is reasonably porous and will absorb lot of water.

In addition I would also like to know at what depth do you encounter bedrock? Recharge wells of 4 to 5 feet diameter constructed using cement rings are the most ideal recharge structures for surface runoff harvesting.

Respected Sri Sekhar Raghavan

I would like to furnish the following data for your kind information.

1)The sub-soil profile is as follows:

a)Moorum Soil-From existing ground level it varies upto a depth of 2 meter to 6 meter

b)Moorum with silty clay (80% of plot area)-6 meter to 21 meter and Hard Moorum (20% of plot area)-6 meter to 21 meter

c)Laterite soil-21 meter to 25 meter.

Soil exploration is not carried out beyond 25 meter. But with all probabily the soil beyond 25 meter could be Laterite soil.Depth of water table in the month of October was around 4.5 meter average.

We have also carried out field percolation test at the site as per IS:2470(PART-2)-1985 in the month of November. The test was carried out at a depth of 5 meter.It is observrd that time required for water to fall by 25mm is 5 minutes.

Water table was not encountered at a depth of 5 meter when percolation test was carried out in the month of November where as water table was at 4.5 meter when the soil exploration was carried out in the month of October.

Now,I would wait for your esteemed observations on the issue raised by me.

Warm Regards.


5. Dear User, Ground water

Dear User,
Groundwater recharge may be taken up by constructing recharge trench with recharge well depending upon the runoff available. It is important to understand the aquifer intended to be recharged. As regards to the overflow form the recharge trench, the same may be diverted to a recharge pond. This would ensure utilisation of entire rainfall runoff.

Dear Mr. Mallick,

This problem is under-estimated. The thing to do is to use a well point system around each structure and collect the water in a temporary pond and inject it deep into the ground where there is porous formation like coarse sand. If such formation is not there, it has to be pumped out to nearest drain.

7. Need to find underground water level in Bidanasi,Cuttack,Orissa

Dear Sir,

We want to dig a borewell in our house for domestic purpose. So kindly advise me as to how many feet or metre we need to dig for all season water.
