  1. WATER CONSERVATION & ENVIRONMENT ENVIRONMENT - HEALTH - SAFETY (EHS) DEPT. LARSEN & TOUBRO LIMITED HAZIRA MANUFACTURING COMPLEX HAZIRA, SURAT, GUJARAT

  2. Can I get some good water to drink…??? DRINKING WATER SCARCITY…

  3. WATER SOURCE & USAGE WATER SOURCE GROUND WATER SURFACE WATER • OCEAN • RIVER • RESERVOIR • LAKE / POND WATER USAGE PURPOSES INDUSTRIAL DOMESTIC • DRINKING • COOKING • SANITATION • CLEANING / WASHING • COOLING • BOILERS • PROCESSING • EQUIPMENT WASHING

  4. RECYLING OF THE WASTEWATER WASTEWATER Chemicals Air & Nutrients • PRIMARY TREATMENT • SCREEN • GREET CHAMBER • COAGULATION / FLOCCULATION • SEDIMENTATION / CLARIFICATION • SECONDARY TREATMENT • AERATION • SECONDARY CLARIFICATION • MBR • TERTIARY TREATMENT • FILTRATION • REVERSE OSMOSIS • ULTRA-FILTRATION • CHLORINATION Sludge to CHWTSDF - site TREATED WASTEWATER (Recycle / Reuse) A ZERO-DISCHARGE FACILITY

  5. RAINWATER HARVESTING NEED DUE TO THE INCREASED WATER CRISIS TO REDUCE SOIL EROSION TO CREATE A CULTURE OF - RAINWATER CONSERVATION RAINWATER HARVESTING RAINWATER HARNESSING LIFE… ROOF-TOP & SURFACE RUN-OFF CHANNELISATION GROUND WATER RECHARGE COLLECTION & STORAGE TREATMENT USAGES LEAD TO REDUCTION IN RAW WATER CONSUMPTION

  6. WAYS TO USE LESS WATER – • Check and fix any water leaks • Install a low-flow shower head • Install water-saving devices on your bathroom/toilets • Don’t wash dishes with the water running continuously • Turn OFF washing machine’s water supply to prevent leak • Follow your community's water use restrictions or guidelines • Replace old toilets with new ones that use a lot less water

  7. WATER MANAGEMENT L&T LTD. - HEAVY ENGINEERING DIVISION – HZMC (ISO 14001 & OHSAS 18001 CERTIFIED) (from Irrigation dept.) RAW WATER STORAGE & TREATMENT DOMESTIC INDUSTRIAL • DRINKING • COOKING • SANITATION • HYDRO-TESTING (JOBS REQUIREMENT) SEWAGE TREATMENT PLANT (STP) TREATED SEWAGE UTILIZED FOR PLANTATION / GREENBELT DEVELOPMENT WITHIN THE PREMISES

  8. WATER CONSERVATION L&T LTD. - HEAVY ENGINEERING DIVISION – HZMC (ISO 14001 & OHSAS 18001 CERTIFIED) • INSTALLATION OF NYLON-ORIFICES TO WATER TAPS FOR FLOW CONTROL • TREATMENT OF WASTEWATER IN S.T.P. • UTILIZATION OF THE TRETAED WASTEWATER FOR PLANTATION /GREENBELT DEVELOPMENT • METERING SYSTEM FOR WATER FLOW MEASUREMENT • RAINWATER HARVESTING FOR ROOF-TOP & SURFACE RAINWATER AT TECHNOLOGY BLOCK (GEEEN BUILDING) • MANAGEMENT PROGRAM TO DEVELOP WATER CONSERVATION PRACTICES UNDER ISO-14001 EHSMS • AWARENESS TRAINING PROGRAMS • TOP MANAGEMENT COMMITMENT (EHS POLICY) FOR WATER CONSERVATION

  9. WATER CONSERVATION L&T LTD. - HEAVY ENGINEERING DIVISION – HZMC (ISO 14001 & OHSAS 18001 CERTIFIED) NYLON ORIFICE FOR WATER TAPS INSTALLED AT HZMC & MHC (10% REDUCTION IN TOTAL WATER CONSUMPTION) PLANTATION / GREENBELT USING TREATED SEWAGE

  10. ENVIRONMENT EFFECT BY WATER CONSERVATION • DIRECT REDUCTION IN RAW WATER CONSUMPTION • REDUCED WATER USAGE - LEAD TO LESS WASTEWATER GENERATION WHICH MINIMIZE WATER POLLUTION (BY VOLUME) • MAINTAINANCE OF UNDER-GROUND WATER TABLE • PRESERVATION OF WATER RESERVE FOR FUTURE GENERATION WHICH IS IMPORTANT FOR SUSTAINABLE DEVELOPMENT • ECONOMIC – WATER BILLING IS REDUCED SO THE PRODUCTION PRODUCTION COST IS GOING TO REDUCED

  11. A SMALL change can make a BIG difference. TOGETHER we can do it. WATER IS A PRECIOUS RESOURCE…!!! CONSERVE IT.
