Dear all
I am Juliana. I took part in the HDPE septic tank study of Hefei Reyao Environmental material construction technology co.ltd two years ago.

I would like to share the Reyao brief introduction with you guys.
Hefei Reyao Environmental construction material technology co., ltd is founded in 2010,which focus on research ,development and production of HDPE molded septic tank, plastic inspection chamber, integration of prefabricated pumping station, solar power sewage treatment equipment etc.

2010 SMC molded septic tank

2011 HDPE double-well corrugated pipe

2012 Integrated equipment for sewage treatment
Integration of prefabricated pumping station

2013 HDPE plastic septic tank
HDPE hollow-wall winding pipe

2014 Participate in the project of Rural Sewage Treatment Zhejiang province

2015 Participate in the project of Rural Sewage Treatment of Shanghai city
Participate in the project of Rural Sewage Treatment of Jiang Su province

2016 Participate in the project of beautiful village construction for Taiping lake, Chaohu lake, Nanling county Anhui province


Reyao HDPE septic tank was introduced widely for projects as its economic price, stackable design, easy installation & transfer, maintenance free. According to research ,Reyao HDPE is highly applicable for Africa and South East Asia too, such as Thailand, Philippine, India, Pakistan, Nepal, Kenya, Ghana, Nigeria etc.Attached specification FYI.

I would like to get a chance to talk more with you all.
HDPE Septic tank get a big success for China sewage treatment project.The original work diagram(3 chambers type) comes from U.S.A and Reyao worked out stackable mold in 2014.The innovation greatly lower the cost and solve the transportation problem.Hope it can be promoted in Africa and Southeast Asia first to solve the local sewage treatment problem.Meantime,i need you guys help to offer the possibility.Thanks.

Attached is the image of Reyao 3 chamber/funnel type septic tank.

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

I just wanted to put a small note here in case you are wondering "is the Forum allowing plain advertising?". It is one of our forum rules that we do not allow plain advertising (see here: forum.susana.org/forum/rules ).
However, the forum, and SuSanA, does welcome private sector participation so I think there needs to be some room for private companies to come in and engage with us.

I have been working with Juliana in the background to assist her in making her post suitable for our forum. I think it's quite good now and I would encourage you to interact with Juliana by asking her questions about her product, their experiences and perhaps give her some advice on how she could expand to other markets (provided you think their product is interesting). I have no opinion about plastic septic tanks, so this is not an endorsement of their product. I am just trying to give more room to private sector involvement in SuSanA (without violating our "no advertisement" clause).

If you have any concerns just contact me, post in this thread or start a new thread (if it's a more general concern).

Regards,
Elisabeth

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

Dear Elisabeth,thanks for your great support and encourage to my post.Appreciate that again.

Europe and U.S.A is getting a perfect sewage treatment system.That is so great.But some Asian and African countries did't have .The roto-molded septic tank and concrete one costs too much.I 'd like to promote it in these areas and sincerely expect some experts help provide proposal to the products and let't move forward it together.

Thank you.

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?

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

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 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 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,

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

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

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
