Re: HDPE septic tank apply to the Rural sewage treatment in China and South east Asia

Dear Julian,

Thank you for the information, very useful given India's sanitation priorities. How does this company (sintex-plastics.com/products/sub-ground-...sintex-septic-tanks/) compare in terms of performance and price. They have been in the business for sometime but I have not seen any of their installations so cannot comment on efficacy.

Regards
Nitya

Re: HDPE septic tank apply to the Rural sewage treatment in China and South east Asia

Mr A.K.Singh,thanks for that.
The HDPE septic tank is maintenance free and no special skills required.
In China rural area,the treated water drain into field for reusing.In downtown,it will re-treated by integrated waste water treatment system.In some other countries,the treated waste water pass into soak away and finally follow into the soil.

Look forward to promoting in India.

Hello Juliana
Very interesting and useful for rural and semi urban condition in India. Any technology transfer agreement with indian industry in near future. What are the issues related to maintenance and any special skill is required. Can treated sewer can be reused in agricultural field.
For any further partnership can we discuss to demonstrate in India.

Please respond

Re: HDPE septic tank apply to the Rural sewage treatment in China and South east Asia

Thanks Nitya
HDPE is wildly used for rural waster water treatment in China.We intend to get entry into India.It applies to all area in South East Asia.I'd email you the cost and more details.
We advise 1500lts for 5-6 household.Rough cost is around usd88 for 3 chamber.The funnel type is much more econoical.

Pls see this image which show the inlet connection with kitchen and bath water water.

Re: HDPE septic tank apply to the Rural sewage treatment in China and South east Asia

Hi Juliana,

Great idea for using in space and money constrained situations. How scalable in terms of both size and money is this? Do you have any presence in India? I'm thinking villages who prefer septic tanks and an informal collection and transport system, but no disposal. Do you have anything that deals with the septage as well.

What's the cost for a typical household use of about 5-6 people, including bath water. Maybe a load of 250 lpd that's a mix of sewage and bath/kitchen water?

Thanks for the information in advance.

Regards
Nitya Jacob

Re: HDPE septic tank apply to the Rural sewage treatment in China and South east Asia

Hi Dana
Thanks for your good question.
Different from Roto molded,HDPE septic tank is injection molded.It improves the production efficiency greatly.Meantime,the transportation cost is much lower.

Pls let me know if you need any more details.

Re: HDPE septic tank apply to the Rural sewage treatment in China and South east Asia

Hi Juliana,

Thanks for sharing information on HDPE septic tanks. I'm based in Ghana and here we have access to plastic septic tanks, 3000 and 6000 liters. They are roto-molded. As you mention the cost is high, approximately twice the cost of a tank make using ferro-cement. How do you recommend producing HDPE tanks to lower the production cost?

Re: HDPE septic tank apply to the Rural sewage treatment in China and South east Asia

Hi Juliana,

Could you please caption each of your images with the product (Elisabeth could help)? I have questions but need to be able to refer to each product by name.

Also, can your company make these out of recycled plastic?

cheers

Re: HDPE septic tank apply to the Rural sewage treatment in China and South east Asia

Hi Kris,thanks for your kind attention to my post.

My answer is as following.
The butyl rubber tape is used for water tight seals, same as double-wall corrugated pipe joint. The actual lifespan of the gasket-like seal can last 25 years . What’s more, 58 pieces of bolts are screwed for strengthening the tightness.
..................................................................................

Sorry I can't upload the images today.I will try again in next days.
.................................................................................


The butyl rubber tape features as below.
corrosion protection of Oil, Gas, Petrochemical, and Waste Water.
Excellent adhesion to inner-layer tape and self
long term corrosion protection , Resistant to UV
High chemical resistance under service temperature.
Cold applied. It makes installation fast and easy.

Hope above information is helpful.

Any further question, please don’t hesitate to let me know.

Good weekend!
Juliana

Re: HDPE septic tank apply to the Rural sewage treatment in China and South east Asia

Stackable is great from a logistical point of view, but of what kind of material is the gasket made that ensures water tightness at the joint? Given the often corrosive qualities of septage, what kind of lifespans can you expect from that gasket before it starts leaking?
