I have dug my borewell till 515 feets after 450 feets I found water. While testing we used five HP motor which gave two inch water flow for 25 mins, afterwards there is continuous flow of 0.75 inch for whole day and if we stop for 1-2 hrs it gives 2 inches water for 15 mins. Please suggest how much HP motor to be fitted for a continuous supply and whether single phase or three phase motor to be fitted?

In our industry, we are having RO system and 30 percent of wastewater is being produced by this system. I checked the TDS of wastewater and it was 3200 ppm. Now I would like to use this wastewater for growing plants. Could you suggest a few varieties that would be able to thrive at this level of TDS.

Hi, I am working in ESBR wastewater treatment plant. We are struggling with a issue of Low MLSS, MLVSS in aeration tank and high COD after secondry clarifier.

  • MLSS-700 PPM, MLVSS- 300 PPM
  • Inlet COD 700-800 PPM and after secondry clarifier it is upto 400 ppm.

So, please suggest how to increase our MLSS/MLVSS and reduce COD in our plant.

Hi, I am looking for groundwater/borewell point identifiers in Tiruvannamalai, Tamil Nadu. I have a farm land I am only looking for scientific surveyors/consultants for drilling a borewell in my farm. Please let me know if you know of someone who provides such service in Tiruvannamalai district in Tamil Nadu. However, I am not looking for old style diviners (coconut, rod etc) as I have already done that and failed.

Can any body help me in solving this? I have a borewell with a depth of 480 ft. Unfortunately, while drilling we encountered mud present at 440 feet along with water. We continued drilling till 480 feet and stopped. Now the concern is at what level the pump should be placed for optimum performance? Also does the water level will improve during rainy seasons?
