Water Tariff in Apartment Communities

  1. 1. The Wishing Well As presented in Water Workshop organized by Avinash Krishnamurthy ( Biome Environmental Trust Rainwater Club Biome Environmental solutions Pvt Ltd
  2. 3. So Why Tariffs for water ? <ul><li>Integral to managing </li></ul><ul><li>Quantity </li></ul><ul><li>Quality </li></ul><ul><li>Tariffs – Single most important economic tool </li></ul>
  3. 4. <ul><li>Cost Account for Water Separately </li></ul><ul><li>(as for energy or any other infrastructure service) </li></ul><ul><li>Don’t bundle it into a single maintenance cost – you lose track of what’s happening </li></ul><ul><li>What cannot be measured cannot be managed </li></ul>
  4. 5. <ul><li>Metering Source </li></ul><ul><li>Metering Distribution </li></ul><ul><li>Metering Consumption </li></ul><ul><li>Metering Waste </li></ul><ul><li>Water Balance – </li></ul><ul><li>Embedded Energy in Water - </li></ul>
  5. 6. Metering a Borewell – Electricity and Water Knowing your numbers
  6. 7. Every household connection METERED !!!!
  7. 8. An Ecological Framework : Water Balance
  8. 9. <ul><li>Capital Infrastructure Costs </li></ul><ul><li>(The borewells, pipes, meters etc) </li></ul><ul><li>Typically already paid up for </li></ul><ul><li>OR </li></ul><ul><li>Raise explicitly monies for implementing new infrastructure </li></ul>
  9. 10. Production cost of water Cost component Example expenses Example Sources of data Cost of maintaining source groundwater management and borewell maintenance Cost accounting monies spent on these (Bills) Cost of pumping from source Borewell / well pumping costs Electricity bills Cost of treating source quality to consumption quality RO system for TDS management Electricity and “Outsourcing” bills Cost of distribution pumping and distribution maintenance Hydro pneumatic pumping, valves, pipes maintenance Electricity and maintenance bills Cost of Conveying waste Sanitation pipes maintenance Cost accounting monies spent on these (Bills) Cost of Waste Water treatment STP running costs Electricity and “Outsourcing” bills Cost of Treated Waste water disposal “ Pumps to throw it out” / Wells to recharge treated waste water to ground / reuse for gardening Cost accounting monies spent on these (Bills) and Electricity bills Ecological Cost of Water : Cost of Returning it to nature at the same quality you extracted it
  10. 11. <ul><li>Go to </li></ul><ul><li>Search for “When Pigs fly : Citizens at the centre of integrated urban water management” </li></ul><ul><li>Download </li></ul><ul><ul><ul><li>Production cost of water tool </li></ul></ul></ul><ul><ul><ul><li>Ecological framework </li></ul></ul></ul>
  11. 13. Principles for Tariff Setting <ul><li>Financial sustainability </li></ul><ul><li>Cover all operating costs (pumping bills,salaries etc) – assuming equity issues not there </li></ul><ul><li>Sinking fund for infrastructure maintenance </li></ul><ul><li>Water supply security </li></ul><ul><li>Water supply continuity fund (digging new borewells) </li></ul><ul><li>Ecological security and responsibility </li></ul><ul><li>Source management / Sustainability fund (eg: recharge and maintenance of recharge, future investments for reuse etc) </li></ul>
  12. 14. Principles for Tariff Setting <ul><li>Demand Management (most important ?) </li></ul><ul><li>Increasing block Tariff </li></ul><ul><li>Incentivize conservative use of water </li></ul><ul><li>Penalize wasteful use </li></ul><ul><li>Let the Water Bill tell the story – its more than numbers </li></ul>
  13. 15. Demand Management <ul><li>Control Lever : Water Tariffs </li></ul><ul><li>Don’t bundle Water charges into other charges </li></ul><ul><li>A Water Bill can be a communication tool (Make your bill tell the story) </li></ul><ul><li>Understand Production cost of water </li></ul><ul><li>Can an increasing block tariff be imposed ? </li></ul><ul><li>Are there mechanisms to penalise wasteful use </li></ul><ul><li>Are there mechanisms to incentivise conservative use </li></ul>Consumption slab Tariff 0 – 10 KL Rs 10/- 10 – 20 KL Rs 15/- 20 – 30 KL Rs 25/- 30 – 40 KL Rs 40/- > 40 KL Rs 60/-
  14. 16. Demand Management <ul><li>Water Literate means Water responsible </li></ul><ul><li>Engage with the community </li></ul><ul><li>Communicate water issues, get the kids involved </li></ul><ul><li>Educate Community </li></ul><ul><li>Provide Data and Information </li></ul><ul><li>Voices for Water !!!! </li></ul><ul><li>Water Efficient Devices </li></ul><ul><li>Taps : Flow rate ? 75lpm or 2 to 10 lpm </li></ul><ul><li>Showers : Flow rate ? 30lpm or 10 to 12 lpm (Bucket Bath ?) </li></ul><ul><li>Water closets : 10/20 litres or 6/3 litre dual flush </li></ul><ul><li>Washing m/c : 150 litres or 70-100 litres, Front loading not top loading </li></ul><ul><li>Bath Tubs : DON’T USE THEM (Bucket Bath ?) </li></ul>
  15. 17. Biome Environmental Trust <ul><li>Urban water and Groundwater research </li></ul><ul><li>Engaging with Schools </li></ul><ul><li>Urban and Rural Sanitation </li></ul><ul><li>Section 12A / 80G </li></ul><ul><li>Donate generously ;-) </li></ul>

  17. 19. A yielding recharge well !!
  18. 21. Rainwater sent for recharge Recharging a bore well Outlet pipe in recharge well
  19. 22. … So What is water quality ?... <ul><li>Is your piped water, borewell water or tanker water clean ? </li></ul><ul><li>How do you know ? Have you tested water you use ? </li></ul><ul><li>And have you tested it after your aquaguard, RO system or whatever-else ? </li></ul><ul><li>BIS 10500:1991 – </li></ul><ul><li>Drinking water Standards for India, 33 parameters. </li></ul><ul><li>Formal water testing conducted in </li></ul><ul><li>Accredited Labs found in cities. </li></ul><ul><li>Water Quality issues to watch out for in cities : </li></ul><ul><li>a) TDS – High TDS in groundwater. Health issues and Problem for Fixtures, pipes, taste etc </li></ul><ul><li>b) Hardness – High hardness in groundwater. Health issues, Soaping, taste and stains </li></ul><ul><li>c) TSS – High TSS – associated typically with surface water sources. Sometimes piped water in blore has silt !!! </li></ul><ul><li>d) High Nitrates and phoshates – Urban area sewage mixing with water or seeping into groundwater </li></ul><ul><li>e) Bacterial and viral contamination – Source of this can be anything including way water is handled and stored. </li></ul><ul><li>f) In specific geologies issues like Iron, Flouride, Arsenic needs to be checked </li></ul>
  20. 23. <ul><li>Good Ground Water Management : </li></ul><ul><li>A component of good water management </li></ul><ul><li>Demand & Catchment Management </li></ul><ul><li>Source and Supply Management (covered) </li></ul><ul><li>Waste Water Management </li></ul>
  21. 24. Waste Water Management What goes around comes around Bangalore Ground water has high nitrates (upto 100-150) Waste Water you throw out comes Back into your borewell
  22. 25. Waste Water Management Is your STP working or is it just getting rid of your waste water ? Do you do regular checks of STP output water ? Is the contract with your STP operator linked to quality of output ? Does he have metrics of performance ? Can you reuse waste water ? Can you separate out different kinds of waste water ? Does your flushing need good quality water ? Can you treat waste water to good enough quality that you can recharge it ?
  23. 26. Dewats
  24. 27. Dewats with Grey water recycle Reuse Waste Water (eg: Grey for flushing, Treated black/grey for irrigation) And use the treated waste water to irrigate Your roof farm that produces food
  25. 28. Getting Maverick : Turn sewage to a nutrient through Eco-san
  26. 29. <ul><li>The choice is yours: </li></ul><ul><li>Want to be part of the solution ? </li></ul><ul><li>or </li></ul><ul><li>Want to be part of the problem ? </li></ul>
  27. 30. Kunju Azhil, 57 Started digging surangas when was 16 Surangas of Kasargod
  28. 32. How much water do I use ? Real Consumption range : from 50 to 300 liters per person per day National Town planning Norms : Urban : 135 Lpcd Rural (Karnataka) : 55 Lpcd How much Water do YOU Use ? Use Litres/person Drinking 3 Cooking 4 Bathing 20 Flushing 40 Washing-clothes 25 Washing Utensils 20 Gardening 23 Total 135
