Needed : Cost Effective & Reduced Footprint Wastewater Treatment System

I'm  from Bangalore and i'm searching for a grey or black water treatment system for my newly constructed house. The catch in my building design is, it is having only a very small area which can be planted / open to sky ( 1'6" x 40' ). When I approched a consultant they said as there is no much open space the scope for the implementation of the conventional reed bed system is very less. 

I'm searching for a system which can handle Max 2500 LPD of black and gray water. In my plan ground floor is left for parking hence the avilable 35 feet x 35 feet can be utilized for the UG tanks or sumps. Is there an option that will help fit in a water treatment system in such a restricted area? 



1. Dear Member, As a solution it

Dear Member,

As a solution it may be required to utlise the space above the UG, and have extended plantation..
It may be required to locate these tanks more deeper...and have say 11/2 Ft. depth space to locate plantation..also have the opening for the top-slab of these tanks..
2ft by 2 ft.. to have man-hole frame and a cover for doing maintainance..
In this way, you would have the tanks tops,,with green- cover..and flowery plants like cayhna- indica..kheli as called in hindi..and Khal tamil..i.e meaning stone banana.. in english...
Pl do asess..the same...
In our earlier e mails.. and in IWP website ... a few pictures..and a layout of a typical arrangement of tanks below ground providing anaerobic treatment and planation above ground giving aerobic process has been explained..
If your daily flow is..2500 litres..i.e 2.5 Kl/ cbm  then you ought to have a volume of 10 times..say 25 kl/ cbm.. waste water retained in septic tank..or reed bed. plantation..or rock garden,, and or a storage for processed/ filered water..etc..Say an average depth of tanks is 1.5 metres.. / i.e 5 feet.. you require an area of 15mtrs..times 1.5 mtrs..
i.e 25 cbm.. 15 mtrs is around 150 sq ft..accordingly it can be managed..
or try a roof garden..or a terrace garden..
You need to feel confident to source waste water either black or grey and recycle..and use for recycling..
The processed water thus ensued from the wwt plant  can be passed through a fountain spary arrangement to provide extended aeration  etc..
can have a flow of water on some planned well sun-lit..aerated ventilated..rock gaden.. and as the water cascades in and out of the stones held in open- rock wouls provide aeration..
The processed water can then be used for secondary purposes..viz.. flushing..irrigation of plants... and others...

5. Needed: Cost effective and reduced footprint system for wastewat

Dear Vipra Bharadewaj

I will suggest a simple and economic system for recharging water used for bathing and washing of clothes which constitute almost 65% of the total water used. In the area of 1.5ft x 40 ft soil space you have, set aside 2.5 sq ft area per occupant in the house. Over this, plant Canna indica at a distance of 1ft between them. Water them with good water for three weeks. Thereafter divert the above water on to this bed. Your grey water will be cleaned and charged into the soil. You can also plant one or two bananas in between and harvest a good crop of bananas. If you get in touch with me, I can give you more details.

6. Needed help sewage treatment-drain water (Kitchen and Bathroom)


I am Bhargav, living in suburbs of Chennai, and I face a very similar problem of having a safe sewage treatment of drain water from bath room, basic washing and kitchen. Our daily drain water comes to around 1000 litres per day. 

We have a separate line from all the restroom/toilets to a septic tank. 

We have the following questions:

1. Can we still use the septic tank to have all the drain water from bathrooms and washing basic, kitchen sink to get collected here (in septic tank).

2. If we need to treat the drain water from batchroom, kitchen seperately, how can we do that?

We live in a 1800 sqft sized plot. 

Please help me with some pointers and also whom i can seek help in Chennai.

Thanks for understanding.




7. Septic tank treatment using in-house cultured microorganisms

Dear Mr. Bhargav,

You can treat all your waste water (from toilets, bathrooms, kitchen and washing areas) in a single septic tank. We provide biological solutions to help you to recycle your waste water for horticulture purposes.
We focus on treating waste by using special in-house cultured microorganisms - that are "pro-biotic" in nature and absolutely eco-friendly.

Septic tanks only partially treat sewage, discharging polluted water leading to ground water contamination. Also, septic tanks without proper treatment get clogged & get filled with sludge, leading to frequent pump out by tankers which is a huge nuisance and is overall a rather unhygienic practice.
We have solutions that utilize the existing septic tanks to treat the sewage using our special microbial culture. You can recycle treated water for gardening or discharge it into the ground water through the soak pit.

Please feel free to contact us for further information.
