7. LANDSCAPE DEVELOPMENT Increasing vegetation in the form of greenbelt is one of the preferred methods to mitigate air pollution. Plants serve as a sink for pollutants, reduce the flow of dust and reduce noise pollution. Calculation of green area for the project is given in Table-9.

Table-9: Calculation of Green Area

Total Plot area 12,140.00 m2

Landscape area required@ 50 % of Open area 3,642.00 m2

Landscape area provided@ 86% of open area or 43.03 % of Plot area 4,373.61 m2 Required number of trees @ 1 tree per 80 sq.m. of plot area 152 trees Number of trees planted both inside the complex and along the project boundary

200 trees

About 200 trees of 10 types of species are planted both inside the complex and all along the boundary to create a boundary of greenery. Selected species of trees planted are:

Saraca indica (Ashoka) Casuarina equiselifolia Cassia fistula (Amaltas) Jacaranda Mimosaefolia (Jacaranda) Erythrina indica (Indian Coral tree) Samanea saman (Monkeypod) Delonix Regia (Flamboyant tree) Oreodoxa regia Lagerstroemia speciosa Caesalpinia pulcherrina

The above selection of trees for the project has been considered to be suitable to the climate and environment of the project area. They are locally available and are commonly used in landscaping. The selected trees are also low in maintenance. Further, majority of selected trees are fast growing and are likely to establish in a short period of time. The fast growth rate and hardiness of the selected trees mean that large specimens could be translated onto the site. The characteristic features of some of the above mentioned species are mentioned below: Saraca indica Leaves are narrowly lanceolate 15-25 cms long, cork-like at the base and with a short petiole. Stipules are intra-petiolar and completely united. Flowers are fragrant. They are 7.5-10 cms across. Calyx is yellow to orange and finally red. Its stamens are 7 to 8. The filaments are filiform.



Cassia fistula They are commonly known as the Amaltas, with its pendulous sprays of deep yellow flowers. In sub-Himalayan and monsoon forests, it occurs thinly scattered, nowhere plentiful, and germinates only through the agency of bears, jackals and monkeys. Delhi has some beautiful amlatas, notably on Amrita Shergil Marg and it is a good tree to plant for its drought-hardiness. Samanea saman Tree normally spread to 25 m high with rough, fissured bark. Leaves bipinnately compound alternate with four to seven pinnae, each pinna bearing two to eight pairs of leaflets, blades ovate to obovate, 1.5-6 cm long, dark green. Flowers seasonally, mostly in spring and summer; flowers many, borne in axillary, flat-topped heads. Corolla funnel-shaped, of five fused petals 7-12 mm long, pink with greenish or yellow tips, and many red stamens 2-3.5 cm long. Fruit a sausage-shaped pod 6-20 cm long with thickened seams. Delonix regia Royal poinciana (so named because it used to be in the genus, Poinciana) is a flamboyant tree in flower - some say the world's most colorful tree. For several weeks in spring and summer it is covered with exuberant clusters of flame-red flowers, 4-5 in (1.2-12.7 cm) across. Even up close the individual flowers are striking: they have four spoon shaped spreading scarlet or orange-red petals about 3 in (7.6 cm) long, and one upright slightly larger petal (the standard) which is marked with yellow and white. Royal poinciana gets 30-40 ft (9.1-12.2 m) tall, but its elegant wide-spreading umbrella-like canopy can be wider than its height. Royal poinciana is deciduous in climates that have a marked dry season, but in Florida and other areas where the winter is not that much dryer than the summer, it is a semi-evergreen tree. Even the leaves are elegant: they are lacy and fernlike, twice-pinnate, and 12-20 in (30.5-50.8 cm) long with 20-40 pairs of primary leaflets (pinnae), each divided into 10-20 pairs of secondary leaflets (pinules). The dark brown pods are flat and woody, up to 24 in (61 cm) long and 2 in (5.1 cm) wide. A naturally occurring variety (var. flavida) has golden-yellow flowers. Casuarina equiselifolia It is selected as the boundary trees which is a fast growing species and grows to a height of about 10 m. It is native to the area and the leaves are dark green, pinnate and approximately 30 cm long. Flowers are yellow and arranged in racemes 45 cm long. The use of the same tree species, therefore, will create a visual connection to the existing surrounding landscape and a massing of trees. The selection of tall, leafy and resilient trees and positioning them along the boundary will also create a noise barrier as well as a filter for vehicular pollution. The use of many leafy large trees is also likely to have a cooling effect and shall assist in absorbing carbon dioxide. The greening of external areas and trees will have an overall physical effect as well as a psychological effect to occupiers’ well being. Lagerstroemia speciosa



It is a species of Lagerstroemia native to tropical southern Asia. It is a small to medium-sized tree growing to 20 m tall, with smooth, flaky bark. The leaves are deciduous, oval to elliptic, 8-15 cm long and 3-7 cm broad, with an acute apex. The flowers are produced in erect panicles 20-40 cm long, each flower with six white to purple petals 2-3.5 cm long. It is planted as an ornamental plant. Besides this, the visual aesthetics of the proposed site is enhanced by developing parks/lawn with local ornamental plants in the open spaces. As adjoining plots are not the agricultural plots, the plantation raised on the boundary (external or internal) of the plot but within the premises, does not results in decrease in productivity of adjoining lands due to shadow effect. The approved site layout plan showing landscape area is attached as Annexure-IX. 8. WATER REQUIREMENT, SUPPLY AND DISTRIBUTION Water Requirement for the proposed project is discussed below. 8.1 Water requirement during Construction phase The construction activity has been done and hence, there is no requirement for water for construction phase. 8.2 Water requirement during operation phase Water requirement during the operational phase is met through New Delhi Municipal Council. The letter of sanctioning of water connection by NDMC is attached as Annexure-XV. The total water requirement for the project is 508 KLD. This includes domestic water requirement, flushing, landscaping, cooling tower makeup, swimming pool and for firefighting tank. The total fresh water requirement is 241 KLD which includes Domestic water requirement. The water requirement for Flushing and landscaping will be met through treated water from STP. Details of break-up of water requirement are given in Table-10.

Reuse of Treated Water: Total waste water generated is 263 KLD, which will be treated in the STP of capacity higher than the waste water generated i.e. 320 KLD. The treated water available is 237 KLD (@ of 90%) and it will be recycled and re-used for flushing, landscaping, HVAC makeup, DG cooling, thus achieving Zero Discharge. During monsoon season, as there will be less water requirement for landscaping, the excess treated water to be discharged to sewer shall be in tune of 10 KLD. The details of recycled water uses are provided in Table-13 below.

Wastewater Treatment Scheme The waste water generated will be treated in the Sewage Treatment Plan, and the capacity of Sewage Treatment Plant (STP) will be higher of waste water generated i.e. 320 KLD. The proposed STP is based on MBR. The schematic diagram of STP is attached as Annexure-XVII. 9. STORM WATER DRAINAGE The storm water disposal system for the premises is self-sufficient to avoid any collection/ stagnation and flooding of water. Maximum harvesting is done within the site. Sufficient rain water harvesting system with suitable dimension at appropriate locations in order to catch the maximum run-off in conformity of Delhi state’s regulation regarding adoption of rain water harvesting. 10. RAINWATER HARVESTING Rainwater harvesting is the activity of direct collection of rainwater. Collected Rainwater is stored for direct use or for recharging the groundwater. Rain Water Harvesting is the technique through which rain water is captured from the roof and paved surfaces and stored in sub-surface ground water reservoir by adopting artificial recharge techniques. Advantages: To meet the ever increasing demand for water. To avoid flooding of roads. To augment the ground water storage and control the decline of water table levels. To reduce ground water pollution. To improve the quality of ground water.



To reduce the soil erosion. To supplement domestic water requirement during summer, drought etc. Improves the quality of ground water through dilution when recharged to ground water. In saline areas, rain water provides good quality water and when recharged to ground

water, it reduces salinity and also helps in maintaining balance between the fresh-saline water inter-faces.

Rainwater Harvesting Calculation for the project is given in Table-14 and Table-15.

Table-14: Numbers of Pits Calculation

As per the calculation provided above, the nos. of RWH Pits is required 2 pits, and we have installed 2 nos. of RWH pits. The Drainage Plan is attached as Annexure-XVIII. 11. POWER REQUIREMENT The total electrical load demand is 2772 KW (2228 KW existing + 544 KW expansion). The source of power supply is New Delhi Municipal Council. The sanction letter of power connection by NDMC is attached as Annexure-XIX. In case of power failure, 2 DG sets of 2000 KVA capacities each are provided for backup power supply system. All 2 Nos. DG Sets are fully synchronized with AMF, Auto Load Management and Auto Load Sharing thru PLC / PCCM (Power Command Control module) for optimum utilization of backup system. The DG sets are water cooled.

SOLID WASTE GENERATION AND MANAGEMENT The project adopts a systematic approach for solid waste collection and disposal. Solid waste generated from the project is collected properly and managed as per MSW Rules, 2000. The domestic solid waste generated by the occupants of the Guest Rooms, Service Apartments, staff and Commercial & Community Population, pertains to the two categories, Bio-degradable and Non-biodegradable. These solid wastes are collected separately by putting three types of separate bins at the source of generation. For the biodegradable waste green bins are provided, for the recyclable waste blue bins and for the non-recyclable waste dark grey bins are provided. For wet garbage, Organic Waste Converter is installed within the complex. The photograph of Organic Waste Converter is attached as Annexure-XX. For Wet Garbage management, agreement has been made with M/s Ganesha Enviro Management Pvt. Ltd. The copy of agreement is attached as Annexure-XXI. The log book maintained for solid waste disposal is attached as Annexure-XXII. The Hazardous waste disposal is done by M/s Lubri Sales India. The latest receipt of Hazardous waste disposal is attached as Annexure-XXIII. The maximum solid waste generation after expansion is about 764.5 kg/day (630 kg/day existing + 134.5 kg/day expansion), and 191.46 kg of sludge (wet basis). Following are the solid waste generation rate has been considered as given in Table-15.
