The right sewage treatment technology in India:

  • Requires minimal electricity to operate.
  • Sequesters carbon as it processes sewage, thus reducing India’s carbon footprint.
  • Should make the most of natural energies and forces such as gravity, sun and microalgae.
  • Removes harmful, disease causing pathogens.
  • Completely treats sewage – reclaiming precious water and nutirients for re-use.
  • Should ensure that water is left with high levels of dissolved oxygen.
  • Has all of the characteristics for sustainable design in a resource and climate change challenged world.

Furthermore, a wholistic solution should in addition include:

1. The amount of sewage the sewage treatment plants along the Ganga River can process every day, should at least equal the amount of sewage that is flowing into the river. To do this well the government will need to project sewage figures for 2020 and plan to build accordingly.

2. Build the number of sewage treatment plants that are committed to, and regularly verify that they are functioning properly.

3. The river must be rigorously monitored and data honestly tracked and recorded, both at point and non point sources. This includes ensuring complete water inventories, pollution tests, identifying contaminants, doing risk assessments to the health and environment, ensuring the adoption of the right approach etc.

4. Do holistically planning, required processes, and pilot projects before beginning the work at a large scale, ie. acquire the land required for the sewage treatment plants before constructing  sewerage pipes.
