Rewatec SOLIDO Sewage Treatment Plant

The SOLIDO Sewage Treatment Plant is the perfect solution to treat domestic wastewater when site conditions require an ultra-compact system.

This technologically-advanced system offers reduced running costs, minimal excavation and a long lifespan.

The Solido Sewage Treatment Plant caters to 6 to 40 PE and incorporates the Sequence Batch Reactor (SBR) technology. Wastewater is treated in batches rather than being treated continuously, resulting in an efficient treatment plant with reduced energy consumption and a prolonged life for all component parts.

Typical applications include:

  • Single dwellings
  • Small communities or developments
  • Refurbishments
  • Rural barn conversions

Minimal Disruption upon Installation

The SOLIDO is a rectangular design requiring 50% (approximately 30t) less excavation than other systems. Installations are often completed within a day or two. The SOLIDO can also be located within driveways, resulting in even less disruption.


The design and the batch treatment process of SOLIDO greatly reduces the need for electrical power. Rated at 0.65kwh per day based on a family of four.


Durable Design

Made with 8mm thick, ribbed polyethylene, SOLIDO is one of the most robust systems on the market. It requires zero concrete during installation – resulting in fast, safe and economical projects.


Reduced Noise Pollution

Peaceful summer evenings in the garden can be enjoyed with zero noise pollution, thanks to a design eliminating noises typically associated with compressors.
