How much is the rural community living sewage treatment equipment

Now most of the rural areas with buried sewage treatment equipment, the country is mainly used buried, there are also containerized. Material is generally fiberglass, carbon steel, rarely stainless steel. The price of good-looking equipment size. Our Kunshan equipment here on average, including construction costs is about 1w / ton, this money is basically the government to come out. The price is ridiculously low to the project is basically unreliable, rural sewage treatment projects, not counting PPP projects such as most of the private sector to do, the gross profit is actually not very high 30% or so, the government bidding before most of the low price in the payment method of the government to be dragged on for so many years. Project completion acceptance, water quality acceptance anyway, a lot of content. Look at the rural sewage treatment market is very large, in fact, do up or very troublesome.
