Better Apartment Management - Water Metering at Samhita Square

  1. 1. Case Study – Water Metering. • Our Apartment Located at Basavanagar, 2 Km away from Old Airport Road • 95 Apartments in 2 Blocks in a 1 Acre Land • Basement + 4 Apartments–in–a–column construction.
  2. 2. To Start with.. • Occupancy started in 2008 • 3 Yielding Borewells • Water Softener installed in 2009 since Borewell yield was coloured Hard Water • Self sufficient ( water supply ) till 2011
  3. 3. Rain Water Harvesting • Attended ADDA Water Workshop in Feb 2012. Decided to Execute the Rainwater Harvesting at the apartment. • Rain water Harvesting completed in June 12. Inline Filters Installed. Filtered water from Terrace- routed to the sump. This would be filtered again by the Softener’s Filter stage before feeding the apartments. • On Moderate rainy Days ( 30 minutes Rain ) Capacity was full. On those days, we could reduce the Borewell usage and Electricity consumption by 50%
  4. 4. Inflection Point • 2012 Summer – We faced reduced yield from the Bore-wells and Increased Electricity Consumption for pumping.
  5. 5. Status during 2012 – 2nd Half • Scanty Rains - Only about 7 rainfalls received that could fill the RWH capacity. • Started procuring water by Tanker from Sept 12 . Additional amount of Rs. 700 collected from each apartment per month, towards Water Purchase • 5 Hour Night Water disruption started officially in Oct 12. ( In reality , disruptions started much earlier ) • New Borewell (950 ft.) dug in Oct 12 and operational in Dec 12 . But the yield was not at all sufficient to meet the demand. • Electricity Usage for Water pumping had become very high. • Bore-well Motors failed twice.
  6. 6. Reaction from Resident Community • Huge Unrest from Residents about Water disruption. • Disruption in Water supply triggers much wastage of water. People collect water and store in containers. And throw away stored water when supply resumes and collects again. • Genuine Users starved of water ( Early Office Goers, Late Returnees) • Leaky Flush Tanks, Forgotten open Taps add to the woes. • Judicious users not at all benefitted of their frugality. • Demand for more Tankers. Opposed by those who consume less.
  7. 7. 2012-13 – Water-Electricity Consumption Sep-12 Oct-12 Nov-12 Dec-12 Jan-13 Feb-13 Mar-13 Apr-13 May-13 Jun-13 Jul-13 Aug-13 No. of Tankers of Water Purchased ( Each Tanker Appx 6000 Litres) 110 111 110 112 110 111 110 115 128 130 142 Electricity Consumption (units) 9550 8919 9307 10774 9555 10623 7953 7461 8686 8861 9284 8778 Electricity Bill ( 1000 Rs ) 56.54 52.83 55.11 63.79 56.57 62.85 47.39 44.26 54.30 55.26 57.89 54.74 No. of Hours of disruption in Water Supply 5 5 5 5 5 8 8 8 8 8 5 - Water Disruption : From Oct 12 : 5 Hrs ( 12 am to 5 am ) From 2nd march 13, 3 More Hours added ( 2 pm to 5 pm )
  8. 8. Bold Step - Water Metering Proposed • Water metering proposed in the April ‘13 GB Meeting • Each Overhead Tank had two compartments– Main ( Borewell Water ) & ‘Kaveri’ ( meant for storing Corporation Water supply obtainable in Future.) • Each Apt. was fed by two sets of Supply Pipes  3 to 4 utility points in the Apartments (Kitchen, Bathrooms / Balcony ) fed by a header pipe from the main tank.  Another point at the Kitchen sink fed by the Kaveri Tank header ) • Decided to keep them as Separate Circuits and provide 2 individual meters for each apartment • Cost Proposed – Rs. 18,000 /- per Apt. • Biggest challenge was in modifying the entire Plumbing lines for the Metering Requirement.
  9. 9. Water Metering Project - Chronicles • Water metering approved in the GB Meeting ( April ’13) • Layout plan , Vendor Finalisation, Material Procurement - (May to June ‘13) • Metering Plumbing Work started in the 3rd Week of June ‘13. • First Block Ready for Trial in Sept ‘13. • 2nd Block Ready for Trial in Oct ‘13. • Two weeks Full Trial in Oct 2nd Half. Data for each week about their consumption and probable bill at that rate of consumption was shared to Users. • Metering formally started in Nov ‘13. First Bill Raised on Dec 1st 2013. • Total Cost of Project = 19.2 Lakhs . Per Apt Share = Rs. 20,000/- ( Increased expenses due to the mid course decision to change Horizontal Terrace Headers from GI to CPVC. Original Plan was to retain the GI Header pipes at Terrace.)
  10. 10. 1.5” GI Header Pipe ( From Main section of O/H Tank ) 1.25” GI Header Pipe From Kaveri O/H Tank. Single Feeder pipes running down and branching to Utility points of all Apts in that column ( Telescopic Plumbing with a single GI Valve) Old Plumbing Arrangement at Terrace , for a column of 3 BHK Apartments
  11. 11. Typical Terrace layout Plan for the Modified Water metering Plumbing Line for a Column of 3 BHK Apartments This column had 4 Apartments T0 – T3 are the ¾” meters for Main Line . t0 to t3 are the ½” meters for the Kaveri Line. 1.5” Pipe Line 1” Pipe Line Valve 1.25” Pipe Line 3/4” Pipe Line T3 T2 T1 T0 t3 t2 t1 t0 T3 t0 Meters Single pipes leading to Individual Apartments From Terrace Top
  12. 12. BEFORE AFTER Single vertical feeder pipe, from the Horizontal Header at Terrace. Horizontal pipes branch out to feed utility points comng in a column of apartments. Individual vertical feeder pipes, from the Apartment’s Meter on the Terrace to the apartment’s utility points
  13. 13. Pipe Routing through Terrace Meter Chamber
  14. 14. Monthly Charges Structure Consumption Slabs Paise per Litre Max amount payable in this slab (Rs.) Water charges for highest consumer falling in this Slab(Rs.)From To 0 1000 Flat amount of Rs. 50/- 50 50 1001 8000 5 350 400 8001 16000 7 560 960 16001 20000 8 320 1280 20001 22000 10 200 1480 22001 12 sky Monthly charges of apartments bifurcated to the following components:  a Fixed component for Maintenance Expenses  a variable component based on the Water Consumption of the apartment of previous month, as per the below Tariff Structure.
  15. 15. Metering – Before and After BEFORE TRIAL AFTER Mar-13 Apr-13 May-13 Jun-13 Jul-13 Aug-13 Sep-13 Oct-13 Nov-13 Dec-13 Jan-14 Feb-14 Mar-14 Apr-14 No. of Tankers of Water Purchased ( Each Tanker Appx 6000 Litres) @ Rs. 600/- per Tanker 111 110 115 128 130 142 70 54 34 31 33 28 30 14 Water obtained from Kaveri supply ( Supply started in Dec 13) ( In Equivalent Tankers ) 5.7 23.8 19.5 20.5 46.2 Electricity Consumption (KWH) 7953 7461 8686 8861 9284 8778 8056 7144 6130 6317 5747 5859 6012 6248 Electricity Bill ( 1000 Rs ) ( Cost @Rs..6.15 per KWH) 47.39 44.26 54.30 55.26 57.89 54.74 50.27 44.62 38.33 39.49 35.95 36.65 37.60 39.06 No. of Hours of disruption in Water Supply 8 8 8 8 8 5 0 0 0 0 0 0 0 0 Per Apt - Per Day consumption Average ( Litres) Unknown ( But definitely Higher) 619 547 495 463 481 487 489 475 0 20 40 60 80 100 120 140 160 No. of Tankers of Water Purchased ( Each Tanker Appx 6000 Litres) Water obtained from Kaveri supply ( In Equivalent Tankers ) Electricity Bill ( 1000 Rs ) No. of Hours of disruption in Water Supply Per Apt - Per Day consumption Average ( HectoLitres)
  16. 16. Fruits of Labor Average Electricity consumption for 8 months prior to Metering (KWH) 8278 Corresponding Cost ( @ Rs. 6.15 per unit ) 50,910.00 Average Electricity consumption for 6 months After Metering ( KWH) 6052 Corresponding Cost ( @ Rs. 6.15 per unit ) 37,220.00 Average Reduction in consumption consequent to Metering (KWH) 2226 Corresponding Average Savings per month ( @ Rs. 6.15 per unit ) 13,690.00 Reduction in Electricity Consumption Reduction in water procurement from outside Average procurement of Tankers for 8 months prior to Metering 107 Average procurement of Water from outside : Tanker + Kaveri supply (which Started in Dec 13 ) : for 6 months after metering ( No. of Tanker Equivalent ) 48 Note :  20% Apparent reduction in Apartment -Per-day consumption averages between Trial period Vs. Post Metering period. Considering the higher consumption prior to the Trial period, the Actual %ge reduction is still higher.  Presently No water is sourced by Tankers. Consumption is exclusively met by the Borewell yield and Corporation Water supply.  As against 5 to 8 Hours of Water disruption prior to Metering , Now there is continuous Water Supply round the clock.
  17. 17. Members from occupied Apartments , wishing to implement Water Metering : • Study your Apartment Plumbing Layout. Each Apartment is Unique. No Common Solution. • Design a system best suited for your requirement. For this , visit the Existing Installations, Discuss with people involved and collect as much information as possible. • Procure Meters beforehand and try out tests , to assess suitability. Suggestions for Implementation of Water Metering System Builders – • When you construct the Apartment, make the Plumbing system in such a way that metering can be implemented easily.
