International Best Practices for Utilities/ Infrastructure Parameters Description Power Supply – 220KV GIS with double bus scheme instead of conventional AIS. – 220/33 & 33/11kV power transformers with N-1 redundancy. – 33 & 11kVRing main unit with Field terminal unit and self healing system. – Underground cabling system Equipments – Compact Substations HT panel, Transformer & LT panels as a combined unit Helps in cost and space reduction Harmonics filters and APFC panel will be connected at consumer load by individual plot owner – Substation Automation System up to metering point, – SCADA Power – Advanced Metering infrastructure Automation – Self Healing System for RMU System – Outage Management System – Smart meters shall be considered for 100% requirement – Roof Top Solar PV to generate ≥ 5% of total power demand Solar Power – Canal Top Solar Plant to generate 1.0 MW power and integrated at 11kv level. – Street Lighting System with 25% standalone solar powered LED lights – Adaptive lamp brightness (average 8-15 Lux will be maintained) Smart Street – LED energy efficient lights Lighting System – centralized lighting management system Water Supply & Wastewater Management (Integrated Approach) – Bulk flow meters of electromagnetic type at strategic points, viz. Inlet & outlet locations of service reservoirs, pumping stations (Potable & Recycled) Flow As DMA meters in the distribution network to monitor the quantum of water Monitoring being supplied Total 14 flow meters (9 in potable water + 5 in recycle water) are installed within the system – For monitoring and reducing Unaccounted for Water (UFW), – To facilitate systematic maintenance District Three District Metering Areas (DMA’s) Metering Areas Bulk flow meters for each DMA (DMA) Individual Meters at Plot levels (Smart Consumer Meters)-100% meter Approach connection. Valves are provided to isolate each DMA – Pressure Monitoring device in distribution network to measure pressure at 12 Pressure locations Monitoring – SCADA / Wireless system for data acquisition at central location – Helps avoid wastage of water due to unnecessary storage – For emergency situations one day storage has been provided in the reservoir (CWR24 X 7 Water 18 Hours & ESR-6 Hours) Supply – WTP should be planned for phase wise development and the reservoir/ water storage tanks should cater the load of 24X7 demand. – Treatment should be at par with WHO/ other stringent standards Recycling/ – Entire non potable water requirement shall be met with reclaimed water from STP Reuse of – Helps to reduce total water requirement by 65%. Reclaimed Water – Water Conservation
Parameters Description Dual Piping – Separate distribution networks for potable and non potable water System – HDPE for both potable and recycle distribution systems Quality Pipes – fewer joints, hence less leakage risk and Fittings – HDPE with electro fusion saddles connection for house service connections – Colour coding of pipes – Black for Potable and Blue for Recycled – Identify unreported bursts and leaks. Active Leakage – Reduce leakage runtime. Control – Prioritization of target areas for leakage inspectors. – Network performance can be monitored. – More accurate, secure & appropriate – Real time data accessibility – Detection and prevention of theft of service – Transmission through the wireless communication media Smart Metering – Automatic/online meter reading and billing – Comprehensive report generation from data – Connected to central SCADA system – Network should be planned to run mostly under gravity but pumping station can be used if terrain/ site topography is a constraints – Use of dual piping system for smaller and larger dia pipes (minimum dia should be 200 mm as per CPHEEO) – Design should be robust and minimum velocity should be maintained at peak hours – Centralized/ Decentralization of STPs should be planned based on network layout and after Techno-Economical analysis – STPs should be planned with tertiary treatment facilities Sewerage & – Reuse of treated waste water should be encouraged for Flushing, gardening and Drainage other non-potable purposes Infrastructure – STPs should be planned in modular basis – Sewerage and Drainage should be planned separately to avoid any management issue and also reduce ambiguity with dry and wet weather flow – SUDS and LIDs should be planned for drainage so as to utilize rain water at maximum extent – Recharge Pits/ RWH and Rain water storage tank should be planned – Outfalls are to be planned where excess water can be drained off without any issue with backflow. Also use some level indicators so as to plan emergency/ disaster relief in advance Solid Waste Management – Waste System Management with waste collection automation – Waste management information and ICT integration – Centralized control Control & – Mobile waste collection solutions (with GIS, GPS, TCS) Automation of Waste – Customer information system, Waste accounting and Billing Management – Mobile work force management – Surveillance System – Preventive maintenance and asset lifecycle management – Introduction of Automatic Waste Collection system – Proper handling and O&M of overall system – Control through ICT enabled centralized system Sustainable and – Mechanical Segregation of waste using Material Recovery Facility Smart – Transportation of waste using closed trucks equipped with GPS for real time traffic Technologies analysis for route optimization – Advanced Treatment/ Processing (incineration, Plasma-Arc, RDF after feasibility analysis) of residual waste before Landfill so as to reduce quantity of inert
Parameters Description – Try minimizing waste at source or at MRF centres only by segregation, recycling, reuse – Organic waste should be treated onsite to generate energy and utilize the residual as manure for internal green areas – E-Waste, Bio-Medical Waste and other Hazardous waste should be collected in separate bins/ collection chamber and should be managed by authorized vendors/ dealers so as to reduce any clash with Municipal waste management.
