Safe Methods for Water Disposal from Laboratory

Published on by in Technology

We are setting up a laboratory and we urgently need a safe disposal method for water from our lab. This is a temporary measure as we wait for the construction of sewer near the vicinity.  Is construction of  a soak pit ideal for this purpose?

  1. What are you disposing of 1000 liter flow bins are a good option and then have them removed by a company that specializes in handling hazardous materials that is option number1: Option number two is build a decentralized treatment plant that you can make use of at any time, however, to make the right choice will depend on what it is that you are disposing of and what effect the effluent will have on the environment. a lined pit is definitely not an option for containment or disposal. solid waste must be incinerated your best option if in doubt contain it flo- bins and get hazmat to remove it for you its not tht expensive. 

  2. I think the first question would be the nature of your waste stream and the contaminants that you expect to be discharging. Without knowing that you might get answers that may not be suitable for your waste stream. 

  3. I would suggest you do not choose the soak pit option as you could contaminate the groundwater.  Maybe consider an evaporation pond - a shallow pit that you will line with a suitable non-porous lining.  Look up the evaporation data vs rainfall for your area (i.e. net evaporation) for the season you need the temporary solution, and size the pond accordingly.  Depending on what the laboratory does, you may need to partially treat the waste, e.g. with lime, if there is a risk to birds or other wildlife.  

  4. Please clarify what do you means by a "soak pit". Are you referring to a leaching pit as used in septic systems? Also, what type of laboratory is being built?

    1. Yes, I meant that. It is a water laboratory for conducting water quality tests  for domestic water and sewage.

  5. It is good practice to separate microbiology wastewater from general lab wastewater for treatment before disposal. This will prevent contamination of the receiving environment with microbes, which could be pathogenic.

    1. This is well noted and will be factored. Thank you

  6. It all depends on your waste - what do you want to dispose?

    1. Effluent from a water laboratory. Connections made only from the sinks.

  9. Do it in IBC then you can bring it to WWTP treatment plant or store at your site and

    1. Thank you Hofmann. I have checked on this and found out that these containers are made of plastic. Won't this be affected by the chemicals used in the lab?..or the effluent should be diluted?
