A septic tank is a large vessel that collects household wastewater through an inlet pipe, treats the effluent through a bio-action process, and releases the treated water into a drain field where the water percolates underground. Ready to install (RTI) Eco Septic Tank adopt container based sanitation, where excreta is collected in sealable containers. This technology is suitable for densely populated low-income urban areas, emergency camps and for areas with high ground water table.

Septic tank provides primary biological treatment to crude sewage produced in a normal domestic environment. It retains solid and allows them to settle in, where they are partially broken down by biological “Anaerobic” action by microbes and bacteria. The remaining liquid effluent is left to flow down towards the outlet drain. The gases such as biogas, carbon dioxide etc. produced stay on top of the effluent and escape through the vent pipe. This effluent further undergoes anaerobic digestion in the subsequent chamber along the long flow path without any turbulence inside the tank ensuring high degree of settlement and sedimentation, thus providing a low level of suspended solids perfectly suitable for discharge into an underground soak-pit.

Specifications of RTI septic tank: Septic tanks come with 3 chamber baffle design system. This ensures a high degree of settlement and sedimentation, thus providing a low level of suspended solids, suitable for discharge into any underground soak away system.

All products are rotationally molded using PLC-Numerically Controlled Machines, in tough LLDPE (Polyethylene) which offers a very high impact resistance. Polyethylene is most resistance to human urine and is seven times more resistant than cement.
Other specifications are:

  • HDPE plastic septic tanks
  • Temperature resistant upto 60o C
  • Smooth interior
  • Chemical and gases resistant

Design and Dimensions

Advantages of RTI septic tank

Leak proof with good sealing properties.

  • Environment friendly.
  • These are easy to install and ready to use tanks.
  • These are good alternatives to concrete and brick septic tanks as they are lighter in weight and rustproof.
  • Suitable for sewage treatment in residential buildings, hotels, schools, hospitals, public toilets etc.

An easy to install RTI Eco Septic tank is being promoted by Eco Concern Pvt. Ltd. to support safe collection of faecal sludge.
