Storm Water Mixing with Sewage

Published on by in Government

What can be done where people are using storm water drains for their sewer to pass and what technology can we use to tackle this problem immediately? 

P.S. Septic tanks built up in the backyard and there is no space in between two houses to construct new sewer line.

  1. Hello The septic tank has septic only the name is actually a storage tank. As proof, the stores the excrement that becomes feces mud. When the tank is full it must be emptied and people are looking for all means not to financially resolve this drain using wild drain: street rainwater, ditch, hole in the ground. Organic sanitation with its biotechnology eliminates all excrements, more draining and especially people water their garden with the liquid at the end of treatment

  2. Bonjour

    la fosse septique n'a de septique que le nom c'est en réalité un réservoir de stockage. Pour preuve il stocke les excréments qui deviennent de la boue d'excréments. Quand le réservoir est plein il faut le vider et les gens cherchent par tous les moyens de ne pas régler financièrement cette vidange en se servant de vidange sauvage: rue, écoulement pluvial, fossé, trou dans le terrain. 

    l'assainissement  Biologique avec sa biotechnologie élimine la totalité des excréments, plus de vidange et surtout les gens arrosent leur jardin avec le liquide en sortie de traitement

  4. It is very common in Indian cities. Public awareness & strict vigilance of local authority can resolve the issue to some extent. Monitor the storm water regularly in non rainy season.

    I will recommend the septic tank followed by the Zero Energy Natural Treatment Process to treat the sewage. Fully treated sewage can join the sewer line. I can share more information with you.  Please write me on sarafrv@virajenvirozing.com

  6. The biggest problem, at least in California, is that coastal and other waterway adjacent cities are allowed to dump untreated wastewater into bays and rivers without consequence.  Until this is addressed via legislation, regulation and penalties, individual solutions will have little impact.

  7. From what I understand from the OP, stormwater drains are seeing sewage disposed of within them.

    The technology to treat waste water / sewage already exists obviously - wastewater treatment systems either at a local, cluster, or centralised scale.  However it may not be appropriate to divert stormwater flows to central WWTPs unless they are designed for irregular loading, or capacity exists to treat the additional volumes of water to the same level as that which the WWTP was designed.  Connecting stormwater systems to pre-existing WWTPs is counter productive in my understanding as the result is an overwhelmed receiving environment (and dilution is not treatment!)

    At a cluster (or catchment) scale, I imagine that sewage could be collected in stormwater retention/detention basins - but this would have massive ramifications to the local environment, not to mention the additional operational costs and maintenance requirements, and the vector for diseases that this would present.

    I can't see the installation of additional septic systems, nor retrofit of blackwater treatment systems to stormwater as being very feasible or practical at a local or cluster scale.

    As easy as it is to say, and as difficult as it may be to employ successfully and at scale, the only "technology" that is going to prevent disposal of sewerage in stormwater is a good behavioural change program (education), with a regular and ongoing maintenance program (sewerage and stormwater networks - are septic systems overflowing into stormwater?), and perhaps punitive measures for those who insist on using stormwater as a sewer.

  8. Sewage disposal can be done by online (Sewer line) system or offline (septic tanks) system. There seems to be no other choice! In your case there is no space available for construction of sewer lines and you are looking for immediate solution, let's rule out this system.

    Septic tank are already constructed. So, all you need to do is direct entire sewage to the septic tanks and then empty these tanks frequently using mobile tankers which will collect the sewage and dispose the same to nearby STP. This is the easiest method considering that you need immediate relief, there is space constraint and it's for residential users. If we discuss about Industrial or commercial clients with space available and considerable resources and technology available at their disposal.

    Also, check the existing Septic tanks for their structural integrity and leakages.

    All the Best!

  9. In some countries and regions stormwater discharge into sewers is illegal, for the fact that the sewage handing system is usually compromised during storm events or massive infrastructure needs to be deployed to receive stormwater into sewers - the latter not always practical.

    So stormwater from houses should be captured and used appropriately, there are several rainwater harvesting, collection and treatment options, systems and technologies available for this application, it should be encouraged wherever we are in the world. An above ground capture system located next to house (on top of septic tank) will most likely fit in your application
