Costing of recharge structures

  1. 1. COSTING OF ARTIFICIAL RECHARGE PROJECTS Baldev Chugh CEO, WATER HARVESTERS NEW DELHI
  2. 2. DRILLING OF RECHARGE WELLS Drilling manually in Alluvial areas – Rs. 100 - 200/- per m. With rig in Alluvial areas – Rs. 400 - 500/- per m. In Hard rock areas with DTH rig – Rs. 1000 – 1400/- per m. Cost of drilling charges reduces if the depth of the drilling is more (depends on negotiations).
  3. 3. CASING OF PVC PIPES  The cost includes filling of gravel and bail plug.  Rs. 250 – 300/- per m. for 4” dia pipe – ISI approved brands.  Rs. 350 – 400/- per m. for 6” dia pipe – ISI approved brands.  Cost may vary depending upon the quality ,Pressure or thickness of pipes.  The cost does not vary much for the slotted portion of the pipes.
  4. 4. EARTH WORKS Excavation includes disposal of surplus, backfilling, labour, etc. Rs. 160/- per cu.m. in Alluvial areas Rs. 300/- per cu.m. in Hard rock areas
  5. 5. PCC FOOTING FOR FOUNDATION  This is required for providing foundation below the brick work.  Rs. 2500 – 3000/- per cu.m.  Cement: Coarse Sand: Stone aggregate (15 mm. or less) – 1:4:8  The sand used nowadays is mainly coarse one like Stone dust, Red sand with minimum silt contents etc..
  6. 6. BRICK WORK  This is required for creating storage in the trench and for filter media.  Rs. 3500 /- per cu.m. approx.  The cost depends upon the quality of brick and cement-sand ratio (1:6 or 1:4).  In recharge structures generally no plastering is done.
  7. 7. FILTER MEDIA  The filter media generally consists of sand, gravel and boulder – inverted filter.  The cost varies from Rs. 1000 – 1200/- per cu.m.  The cost includes material, labour, levelling, transportation, etc.  The cost variation for sand, gravel and boulder is not much and are within a specified range.
  8. 8. RCC SLAB  This is used to provide cover to the recharge trench.  They are mainly detachable, so as to undertake regular maintenance.  Fixed Slabs may be considered with manhole provisions  The cost varies from Rs. 3000 – 3500/- per cu.m.  The cement:sand:stone aggregate (20 mm. or less) – 1:2:4
  9. 9. TOR STEEL - REINFORCEMENT The cost is generally Rs. 35 - 40/- per Kg. This includes transportation, labour, binding wire, cutting, etc. The spacing of the Tor Steel are generally 6”, 4” or 3” depending upon the cover span of the area & thickness of the RCC slab/strength required (generally the slabs are 7 cm./10 cm./15 cm. thick). Cement Mortar ration should be 1:2:4 (1- cement:2-coarse sand:4-stone agg. 15mm or less)
  10. 10. SHUTTERING  Shuttering is mainly to provide cushion for RCC slabs.  Cost for shuttering is generally Rs. 300/- per Sq.m.  The cost includes transportation, fixing, shuttering, binding, labour, etc.  The cost principle says, less area – more cost and vice versa.
  11. 11. INLET AND OULET PIPES Rs. 300 – 400/- per m. for 10” dia. RCC pipe. Rs. 300/- per m. for 6” dia. PVC pipe. The cost includes for material only and does not include transportation, etc.
  12. 12. MISCELLANEOUS CHARGES  This includes contingencies, in-house transportation, site clearance, etc.  The cost varies from Rs. 1000/- to Rs. 2000/-.  The cost depends on the size of the trench/pit.
  13. 13. OPTIONALS - PLASTERING  This is done where the trench is near to the basement or it is intended to recharge through recharge well only.  Rs. 150/- per Sq.m. with 12 mm. thick plaster with Jamuna sand.  Cement:Sand – 1:6 on walls and 1:4 on the bottom of slab.
  14. 14. OPTIONALS – FINISHING WITH FLOATING CEMENT  Plastering of slabs and finishing it with a floating coat of neat cement is required in certain specific sites where the recharge structure is located on the front of an institutional campus.  Rs. 150/- per Sq.m. with 12 mm. thick plaster.
  15. 15. OPTIONALS – MS COVERS  Rs. 35/- to Rs. 40/- per Kg.  The cost depends on nature of angles, square bars, flat hinges, fabrication, etc.  This type of covers are one of the substitutes for RCC slabs.  SFRC covers are also in use—cheaper option will cost around Rs.800/- for 600x450mm
  16. 16. THUMB RULE OF COSTING Rs. 5000/- per cu.m cost towards civil work Plus drilling & casing cost as per soil formation Plus Rs.500/- to 700/- per R.mtr cost towards channelizing
