Objective : 1. Stop or Reduce present dependance on external water sources 2. Aim for Zero-budget Closed loop recycling water system 3. KIT's own usage model can become example of best Eco-Environmental approach & methodology of best practices. 4. Integrate with PBL and involve student/faculty teams as part of learning program
Methodology : 1. Water Budget : Input - Output Modelling 2. Build Total Resource Inventory with visual information, mapping of resources on campus 3. Mutli-level use of resource at various levels of degradation by recycling and grading use quality requirements
Hydrological System Model & Inventory :
1. KIT Campus boundary 2. Larger watershed feeding KIT Hydrology GIS, contour data 3. Assess throughput from larger system passing through KIT Volume of Water; Duration, Period, Surface run-off, Sub-surface flows. 4. Preciptitation over KIT Campus of 27 acres 5. Area of paved surfaces with run-off flowing to drains 6. Built Areas, natural drainage, runoff and Harvesting potential. 7. Present Storage areas : 1. Open Well : Volume, Duration, period, daily uptake and recharge time, volume 2. Storage tanks : Overhead, underground, volume, linked to which buildings? 8. Surface water storage areas, efforts, volume, trenches, bunds, sizes 9. Geological profile of site Data from GSDA, consultants, vertical section profile, permeable. impermeable zones, depths, Soil types, Ground cover, Water retention, Organic carbon 10. Mapping of Plumbing of water supply main lines, branches to buildings, individual buildings 11. Mapping of drainage system, septic tanks 12. Water Audit : Consumption types & volume : Toilet, Bath, Washing, Canteen, Drinking, Workshops, Cleaning, Garden Provision for fire fighting needs 13. Daily, Monthly, Annual consumption 14. Water brought from outside systems : Gram Panchayat, Tankers, Volume,Costs 15. Tree cover, location, species, density, shade index 16. Solar insolation data, Evapo-transpiration losses of open water ponds, storage 17. Contour bunding calculations, volume, outcomes, costing
Strategies, solutions 1. Surface water harvesting through Keyline Method (Yeoman), Contour bunds, maximize run-off through site, small decentralized storage ponds. Impervious lining, polymer fabric / cement fabric. 2. Ground water prospects for bore well, perched water table 3. Augment groundwater strata by bore blast fracturing of impervious strata 4. Improve groundwater recharge and retention by increasing soil carbon and ground vegetative cover. 5. Reduce evapo-transpiration losses through vegetative cover like Azolla, Water Hyacinth and general shade through tree cover. 6. Multiple level use of degraded water by recycling, separate plumbing, filtering, and storage for secondary uses like toilet flushing, urinal flush, garden use. 7. Use water efficient plumbing and fixtures, leakage monitoring smart systems. 8. Building rainwater harvesting systems to be decentralised. Storage at point of use. 9. Increase green cover by creating natural ecological landscape in niches, no maintenance human forests. 10. Swales for natural irrigation for needs of landscaped areas of campus.
Congratulations! Good start. Let us bring all info relevant to the project on this blog.
