Expansion of KC Valley Project for Wastewater Reuse Nationwide

  • Government Initiatives:
    • Plan to replicate Karnataka’s KC Valley project nationwide to promote wastewater reuse.
    • Consideration of partial funding through the Atal Bhujal Yojana to address groundwater depletion.
  • Current Project Overview:
    • KC Valley project supplies treated water from Bengaluru to replenish lakes in arid districts like Bengaluru Rural, Kolar, and Chikkballapura.
    • Success in groundwater recharge prompts its implementation for lake rejuvenation in other states.
  • Proposed Enhancements: Upgrading the project for better tertiary treatment and bio-remedial measures to improve water quality.
  • National Wastewater Generation: India generates 72,368 MLD of wastewater daily, highlighting the need for effective reuse strategies.
  • Recent Initiatives: Launch of the Sujalam 2.0 greywater recycling project to reuse kitchen, bathing, and laundry runoff.

Concerns Raised by Farmers:

  • Some farmers in Kolar express opposition to using treated water due to concerns about groundwater quality and crop health.
  • Farmers attribute reduced yields and pest infestations to treated sewage water, claiming increased pest and fungi resistance since the project’s inception.

Atal Bhujal Yojana (ATAL JAL):

  • Objective: Facilitate sustainable groundwater management.
  • Budget: Rs. 6000 crore, with Rs. 3000 crore as a loan from the World Bank and Rs. 3000 crore as a matching contribution from the Government of India (GoI).
  • Financing Method: World Bank financing under the Program for Results (PforR), disbursed to the GoI based on pre-agreed results for onward distribution to participating States.
  • Funding Disbursement: Funds provided to States as grants-in-aid.
  • Implementation: Covers 8220 water-stressed Gram Panchayats in Haryana, Gujarat, Karnataka, Madhya Pradesh, Maharashtra, Rajasthan, and Uttar Pradesh.
  • Focus Areas: Emphasizes community participation and demand-side interventions for sustainable groundwater management in identified water-stressed areas across seven states in India.

Greywater vs. Blackwater:

  • Source: Greywater originates from household activities like laundry, showering, and bathroom sinks, while blackwater comes from toilets, kitchen sinks, and dishwashers.
  • Contact: Greywater typically does not come into contact with fecal matter, while blackwater contains both urine and fecal matter.
  • Origin: Greywater is a byproduct of domestic activities, whereas blackwater is sewage.
  • Contamination: Greywater poses minimal contamination risk and is easier to filter and clean, whereas blackwater contains harmful bacteria and is highly contaminated.
  • Reusability: Greywater can be filtered and cleaned for reuse in the garden, while blackwater is extremely difficult to filter and clean for reuse.
