The Problem with Current Water and Sewage Treatment Plants

Africa presents a challenge for water and sewage treatment plants. Lack of basic infrastructure for water and power; unreliable service delivery, lack of maintenance or expansion of aging systems; and communities with limited access to grid supply pose difficulties when designing solutions for water and wastewater treatment. In addition, the logistics and costs involved in delivery and installation further aggravate the situation faced by many communities on the continent.

While no single requirement is exactly the same, sometimes a one-size-fits-all approach, while still maintaining a level of design flexibility, is needed to ensure that communities and industry are able to receive basic services. This is where the package solution offers distinct benefits.

What are Package Plants?

Packaged Sewage Treatment Plants
An example of a package plant.

At its basic level, a package plant is an off-the-shelf, decentralised solution for water and wastewater treatment that bypasses the need for massive investment in piping, pumping, reservoir and instrumentation infrastructure.

Package Plant Design

Integrating a modular design, it can be transported easily to site and assembled (usually in a standard shipping container) either as a standalone solution or as part of an expansion of existing infrastructure. Its size and throughput can also vary from small scale systems capable of servicing a few hundred users to larger systems designed to meet the needs of thousands of users.

Package Plant Offering

WEC Projects has taken the concept to the next level by engineering package solutions that can be further customised to meet specific requirements as well as integrate resource recycling and reuse for water, nutrient rich waste, bio-gas and energy.

The ability to address the water and wastewater treatment requirements of African communities and industry gives WEC Projects a distinct advantage.

A package solution for water treatment up to potable standards can be achieved easily using local water resources such as boreholes, rivers and dams, and salt water sources such as marshes and oceans. In addition, a package solution can be used to expand existing water treatment facilities quickly and economically, eliminating the need for large capex investment.

Water Treatment Technology Integration

WEC Projects package water treatment solutions are available in sizes ranging from 30m3 to 550m3/h and can integrate a variety of technologies such as:

  • Clarification
  • Sand filtration
  • Chemical dosing
  • Water softening
  • Ion exchange
  • Cartridge filtration
  • Ultrafiltration
  • Nanofiltration
  • Reverse osmosis
  • Desalination
  • Disinfection

These solutions will bring treated water to the required standards for applications such as potable water, industrial processes, irrigation and dust-suppression.

Sewage Treatment Package Plants

Ensuring effective sanitation for communities and industry in Africa is of paramount importance if the continent is to grow its economies. At the same time, solutions need to be cognisant of the need to ensure that resources such as water and energy are preserved through reclamation and re-use and that effluent and solid waste are kept to a minimum and comply with local environmental standards.

WEC Projects has extensive expertise in the design and delivery of customised package sewage treatment solutions utilising either aerobic or anaerobic for small scale community and industrial applications to high-end multi-stage systems for municipal and large industrial applications. In addition, plants can integrate resource recovery capabilities for reclaiming/recycling for irrigation purposes.
