For Residential Developments

In today's world, building an apartment complex or a residential area also requires considering how to deal with the accumulating waste water. Most industrial countries in the world require 100% treatment. Many developing nations also increased their regulation in the area of waste water treatment over the years and do request developers or owners of apartment complexes and residential areas to either treat the accumulating waste water on their own grounds or to connect their sewage system to public sewage systems with proper treatment plants. Therefore, whether you are building one apartment building or a large residential area, the issue of waste water accumulation and treatment needs to be dealt with early on in the project.

Certainly, there are many different options in how to deal with this topic. Often, the most convenient way is to connect to the public sewage system. However, in some cases this might not be possible or not desirable from a developer's point of view. Some might like to use the treated water themselves e.g. for irrigation or for artificial lakes. Others are too far away from public sewage systems or do not trust municipal treatment systems. They rather seek independence to achieve maximum system availability and better and stable effluent quality with their own treatment plants. Indeed it is a suitable solution to have a treatment plant built for the specific development (and potentially for neighboring developments as well).

The waste water treatment solution has to fulfill some basic requirements. It has to perform perfectly well 24 hours a day, 7 days a week and 365 days a year without unpleasant side effects such as odor and noise. It must not endanger the safety of the people living on the grounds (not acquiring diseases from contact with untreated waste water); it must be in line with regulations, be cost efficient and at best be invisible or fit into the overall architectural plan of the development so as to avoid spoiling the development's appearance.

If you are a developer of an apartment complex or a residential area facing these types of issues and like to have your waste water problem solved with a solution that fits your needs, consider our product and service offerings.

Erection of treatment plants

  We design and build state-of-the art waste water treatment plants exactly fitting your requirements in terms of size and application.

  Growing residential areas benefit from our plant's modular design. The rectangular construction of the BIOCOS® tanks for example ensures easy plant enlargement in the future. There is no need to invest money in future capacity requirements today.

  In comparison to other sewage treatment systems, our plants require less technical equipment. Consequently, there is a lower initial investment and there are lower operational costs.

  Our plants fulfill and often exceed strict European limits for biological waste water treatment, while consuming less energy than comparable conventional plants. This is especially relevant for residential complexes that like to use the treated effluent for irrigation. Our plants produce hazard free water, so you do not need to worry about potential health problems for the resident . Furthermore, the very high cleaning performance of the BIOCOS® system results in very low nitrate, ammonium and phosphate concentrations of the effluent. Hence, when the effluent is used for artificial lakes, algae growth is hampered. On the other hand, the nitrates and phosphates are bounded to the excess sludge, which in a dried from can be used as perfect fertilizer.

  We can build covered plants to avoid any odor coming out of the plant, however even open plants generally do not smell. The plants can also be built underground to save precious space and to maintain unobstructed views.

Maintenance and operation of treatment plants

  Besides manuals and training for local plant personnel, provided in the client's language, we offer a range of maintenance packages to ensure the availability of your plant.

  We can also operate your plant no matter what size (as long as it has been built or rebuilt by us).

Rebuilding of existing treatment plants

  If you own plants that are too small, too old or just do not perform according to your requirements and expectations, we can convert them into BIOCOS® plants.

  When converting plants into the BIOCOS® technology, we will use as many of the existing structures as possible to keep the investment to a minimum (of course without endangering the new plant's performance).

Financing support and consulting for waste water treatment

  We have established relationships with major international banks that do infrastructure financing for private developments.

  We offer consulting services to find the right solution for your specific waste water problem even if this solution is not BIOCOS®.
