叙利亚采购需求：家庭污水处理厂

I'm interested in your domestic sewage treatment plants suitable for a farm house application. Could you please provide detailed pricing information, including any variations available? Additionally, I'd like to know the shipping options and costs associated with sending the unit to Syria. If you have any specifications or features that would be beneficial for a farm setting, please share those as well. Understanding the installation requirements and maintenance support would also be helpful. Looking forward to your prompt response!
