(d) Building with Soft Storey 'In case buildings with a flexible storeys, such as the ground storey consisting

of open spaces for parking that is“Still building” or any other storey with open halls,special arrangements are to be made to increase the lateral strength and stiffness of thesoft/open storey such as Steel bracingl Shear walls /Brick infills between columns.Dynamic analysis of building is to be carried out including the strength and stiffnesseffects of infills and inelastic deformations in the members. particularly; those in the

Page -1'2

soft storey and the structural members are to be designed accordingly. Alternatively.the following design criteria are to be adopted after carrying out the earthquakeanalysis, neglecting the effect of infill walls in other storeys: - R

The column and beams of the soft storey shall be designed for 2.5 times thestorey shears and moments, calculated under seismic loads specified in theother relevant clauses: or _

b. Besides the columns designed and detailed for the calculated storey shears andmoments, shears walls shall be placed symmetrically in both directions of thebuilding as far away from the centre of the building as feasible; to be designedexclusively for 1.5 times the lateral storey shear force calculated as before. Fordetails ofdesign and provisions, IS 1893, Pan 1 shall be referred.

comparison of a number of possible alternatives of structural schemes and determine the mostcost effective one. detailed structural calculations are jnot necessary for each alternativescheme. However, it is conservative assumption it is possible to derive simplified calculationsfor analysis and design. This is called “Preliminary or appropriate analysis. and design"

After the most cost effective scheme is selected and signed—off by the Client, the detailedcalculations are performed on the selected scheme to determine the precise structural members and

surfaces on which rain falls, and subsequently storing this water for use. Therainwater collected can be stored for direct use or can be recharged into theunderground aquifers. In scientific terms water harvesting (broadly) refers locollection and storage of rainwater from the rooftops. This also restricts evaporationand seepage into building foundations. All building having plinth area not less than200 sq.m., while submitting the building plans for sanction, shall mandatorily includethe complete proposal ofrainwater harvesting.

rainwater on surface for future use and Recharge to ground water.

The technical aspects and options of Rainwater harvesting are as follows:The storage of rain water on surface is a traditional technique and the

structures used were underground tanks, ponds. check dams, weirs etc. Recharge toground water is a new concept of rain water harvesting and the structures generallyused are:-

1.

i. Pits: Recharge Pits are constructed for recharging the shallow aquifer. Theseare constructed 1 to 2m wide and to 3m deep which are back filled with boulders,gravels. coarse sand.

ii. Trenches: These are constructed when the permeable steam is available atshallow depth. Trench may be 0.5 to 1m. wide and 1 to 1.5m. deep and 10 to 20mlong depending up availability of water. These are back filled with filler materials.

iii. Dug wells: Existing dug wells may be utilized as recharge structure andwater should pass through filter media before putting into dug well.

iv. Hand pumps: The Existing hand pumps may be used for recharging theshallow/ deep aquifer. if the availability of water is limited. Water should passthrough filter media before diverting it into hand pumps.

v. Recharge wells: Recharge wells of 100 to 300 mm. diameter are generallyconstructed for recharging the deeper aquifer and water is passed through filter mediato avoid choking of recharge wells. .

vi. Recharge Shafts: For recharging the shallow aquifer which are locatedbelow clayey surface, recharge shafts of 0.5 to 3m.diameter and 10 to 15 m. deep areconstructed and back filled with boulders, gravels & coarse sand.

vii. Lateral shafts with bore wells: For recharging the upper as well asdeeper aquifers lateral shafts of 1.5 to 2 m. wide & 10 to 30 m. long depending uponavailability of water with one or two bore wells are constructed. The lateral shafts areback filled with boulders, gravels & coarse sand.

viii. Spreading techniques: When permeable strata from top then thistechnique used. Spread the water in streamsfNalas by making check dams, nala bunds,cement plugs, gabion structures or a percolation pond may be constructed.

(3) Harvesting provisions in various Building categories:All building in a city contribute to the rain water runoff during the monsoon

and hence such runoffcan be harvested for water reuse/ recharge.

city’s geographic area. All such public open spaces above the size of 500 sq.m shallhave arrangements for complete utilization and capture of storm water with scientificrain water harvesting arrangements. s

Following ideas may also be included: ‘i) Well cum Channel cum percolation pits.ii) Use of abandoned bore wells for recharging of ground wateriii) Artificial or natural storage of storm water runoff from larger sites.

(5) Ground Water Recharge

Recharging of ground water should be made mandatory not only forresidential building but for all types of buildings, including Group Housing Societieshaving a plot area more than 500 sq. m. and above. ' .

The Ground Water Recharge should also be mandatory for open spaces likeparks, parking, plazas and playgrounds. The harvesting and recharge structures couldbe constructed by the authority with the involvement’ of community basedorganizations like Resident Welfare Associations. l '.1.

(6) Enforcement and Monitoring "i. The ULB shall constitute a rainwater Harvesting Cell which will be

responsible for enforcement and monitoring of the Provisions of RainwaterHarvesting. The cell shall employ qualified persons who are well versed with theinterpretation of Building Bye Laws and responsible for enforcement as well asmonitoring the functioning of the Rainwater Harvesting System.

ii. The Authority shall include inspection of rainwater Harvesting Structuresbefore issuing Completion Certificates or NOCs for service connections to theproperty.

iii. Set an example in the city by ensuring that Rainwater is harvested in theproperties/ assets owned by them including public building, markets, communitycenters, parking spaces, roads and parks etc.

iv. the Authority shall also establish a mechanism to monitor 100% of RWHprovisions in all the building above 1000 sq.m with annual physical verification,while building less than 1000 sq.m. can be monitored on the basis of 10% randomsurvey by competent authority. '

v) With regard to open public spaces viz., Parks, playgrounds etc, theimplementation of provision rainwater harvesting may be done with the help ofResidents Welfare Associations, Community Building Organizatin and Non-Giovernmental‘Organisations. i

vi. The “Authority shall ensure earmarking budgetary provision for the creationand maintenance of rainwater harvesting structures in public spaces owned andmaintained by them, like parking spaces, parks, plazas etc.

vii. The practice of incentives and penalties to promote rain water harvestingshall be formulated by the ULB based on best practices. ULB shall design its ownincentive and penalty systems, considering the water level and scarcity.

lb) Water Re-use and Recycling: - All non-residential buildings having adischarge of 10,000 litters and above per day shall incorporate wastewater re-cyclingsystem. Recycled water should be used for horticultural purpose."
