2.4 Source

Water will be sourced from the following source:-

o Municipal Supplyo Tanker

The clients may need to furnish information with regard to the availability of water from all the abovetwo sources.


8/133



2.5 Water Treatment System

In order to decide the exact treatment to be adopted, it is essential to know the chemical composition of raw

water as per IS 10500. Efforts should be made by the clients to get the water samples tested from all the

possible sources. If there is no tube well existing at site, sample may be taken from some other tube well

existing in the vicinity of the site.

In general practice following water treatment system will be adopted.

The water from the source will be brought into the underground fire static tank to overflow into the raw

water tank. Water from this tank shall be treated in the water treatment plant, consisting of

chlorination, filtration (DMF - Dual Media Filter) and optional softening units, located in the plant room.

Domestic water shall be supplied after chlorination and filtration. A certain amount of water may also

be softened and blended with the domestic water to reduce the water hardness to permissible levels.

The domestic water shall be stored in the domestic water tank. Municipal connection shall be directly

brought into the domestic water tank.

2.6 Pumping, Overhead Storage & Distribution System

2.6.1 Domestic Water

For pumping and distribution of domestic water to tower, the gravity system is being proposed. The

domestic water from underground domestic water tank shall be transmitted via variable speed

pumping system to all the overhead tanks located at terrace levels of each tower depending upon

heights, and from there the water shall be supplied by gravity to all user points. The system shall be

designed to take care of peak demand of water and a residual pressure at the ground floor users point

shall be minimum 1.5 kg/cm2. Since the pressure in the lower floors shall be high, pressure reducing

valves shall be provided to maintain reasonable pressure. The low rise building club/nursery school

will be feed thru extended by the gravity line from nearby towers with pressure reducing station at

ground floor level or separate pumping system as per requirement. The top four floors will have

separate hydro pneumatic pumping system. (Min 1.5 kg/cm2

)

Each tower shall have an OH tank (Domestic) as per requirement.

Water supply system will be completely automatic through mechanically operated valve with level

controller. The ON/OFF operation of the motorized valve will get signal from level controller placed in

domestic water tank.

2.6.2 Flushing Water

Since the recycled water from STP is to be used for flushing, an independent system of pumps, pipes

and overhead tank in each tower shall be provided. This water shall be used only for flushing and

ablution taps/health faucets shall be connected to domestic water.

Similar pumping system is proposed for flushing water system as described in Domestic water

system.

Each tower shall have an OH tank (Flushing) as per requirement & mechanically operated valve with

level controller. The ON/OFF operation of the motorized valve will get signal from level controller

placed in flushing water tank.

SEWERAGE SYSTEM

3.1 As per MOEF requirement it is mandatory to provide STP and same shall be done for this project.

3.2 It is proposed that the sewage generated from the entire tower shall be treated in a sewage treatment plant,so that the treated effluent can be recycled for horticulture, flushing & soft water requirements of the site &balance treated water can be sold to outside agencies. So that site will be ZERO discharge site.

Design Conditi ons

a. Termination of vent cowl at terrace level.

b. Provision of adequate slope for horizontal header pipes in the ceiling level of the floor for achievingself-cleaning velocity in the pipes.

c. Provision of cleanout plugs.

d. Provision of the system services maintenance.

3.3 System Designed

The sewerage system will be based on conventional water carriage system, in which soil anddomestic waste generated by individual buildings/units will be collected into a collection chamber,through soil and waste piping system.

The sanitary, waste & vent system shall be water tight and gas tight designed to prevent escape offoul gas and odour from various fixtures.

Provision of ASP vertical vent shall be made for hygiene, safety considerations, and to avoid entry offoul smell into occupied areas.

Vent system shall be designed to facilitate escape of gases and odour from all parts of sanitary andwaste system to the atmosphere at a point above the building and to allow admittance of air to allpart of the system, so that siphonage, aspiration or back pressure conditions do not cause loss of

seal at traps.

It is proposed to use uPVC SWR pipe for soil/waste application. The soil & waste piping from toiletshall be connected vertical stack located inside the pipe shaft which shall be coordinated with otherservices and in consultation with the Architect.

The collection chamber from all units shall be connected to the nearest manhole on the externalsewer line planned along the periphery of the building and as per site conditions.

It is recommended that the domestic sewage shall finally be carried due to gravity to one disposalpoint for further treatment in the Sewage Treatment Plant.

Phase - 1,As per calculation total domestic water consumption, is about 488 m3/day. For designingthe STP it is considered that 80% of water consumed gets converted in to sewage. Based on thisfundamental the capacity of STP shall be 391 m3/day. But for working point, we are proposing STPcapacity 460 KLD as per EIA requirement.


3


22/133




EWS, Nursery & Primary Schools,As per calculation total domestic water consumption, is about208 m3/day. For designing the STP it is considered that 80% of water consumed gets converted in

to sewage. Based on this fundamental the capacity of STP shall be 170 m3/day. But for workingpoint, we are proposing STP capacity 210 KLD as per EIA requirement.

Treated effluent shall be filtered through Dual Media Filter (DMF) & Activated Carbon filter (ACF)and stored in an UG tank for use in flushing and Horticulture.

Further filtered water will be softened and used for DG Cooling tower.

3.4 Basic characteristic of incoming and outgoing parameter are as follows:

Parameter Raw Sewage Treated Sewage (Incoming) (SAFF treatment)

DRAINAGE & RAINWATER HARVESTING SYSTEM

4.1 Introduction

Due to urbanization of the land and sharp growth in population and thus increase in water demand forvarious uses, the fresh water is becoming scarce in most regions of the area. In certain areas due to almosttotal dependency on the underground water, the wells and bore-wells are getting deeper and deeper. Also

due to increase in paved surface/roof areas, the amount of natural/percolation of rainfall is reducing verydrastically.

Therefore, it has become very necessary to harvest the rain water as maximum as possible. The drainagesystem needs to be planned with a view to incorporate rainwater harvesting principles.

Separate and independent rain water drainage system shall be provided for collecting rain water fromterrace, paved area, lawns and roads. Independent rain water down takes of appropriate size and numbershall be provided in apartment toilet shafts & other dedicated shafts. The final disposal shall be in rain waterharvesting pit with overflow connection to the municipal storm water mains for the site. Perforated pipedrainage system shall be provided for open-to-sky courtyards/lawns.

Drain channel shall be provided in the car parking and pump room areas within the floor-fill. Drain channelsshall be provided with adequate slope to effect self cleaning velocity and shall terminate in sumps. For eachsumps, 2 nos submersible pumps (1 working + 1 standby) shall be provided for disposal of collected run-off.Pumps shall be installed in identified sumps and shall be operated by Hi-Lo level switches with automaticchangeover between both pumps. Provision of water detector/alarm shall be made in each lift pit. Portablepumps shall be lowered in the lift pit when water logging is detected, to enable disposal of surface runoffwater.

4.2 Systems of Rainwater Harvesting:- The sub-soil met the course of investigation consist of predominantlygravelly silty fine sands up to termination depths of 25.45M & silt layer between 6.0 & 7.5 M depth. The subsoil to have gravel /Kankar at all depths but beyond between 9.0 M & 18 M appreciable percentage.

The Sub Soil is alluvial deposit. The stratification at site indicated layered deposits caused by sedimentdeposition by streams in non marine fluvial condition. The deposit is known as alluvium. The sub soil islayered deposit consisting of fine sand with gravel/kankar. The sub-soil is cohesion less deposit. They areinorganic and non- plastic. The standard penetration values observed at site indicate the deposit to bemedium dense up to 21.0 M below which they are dense. The field penetration value increases with depth,indicating they are normally consolidated deposit. The N values observed at site are influenced due topresence of gravel/kankar.

As the sub soil is cohesion less deposit, any long-term settlements are unlikely. Most settlement if any arelikely to take place during construction period itself except for creep. Water table varies between 10.5M to11.15M in the month of Nov/Dec, 2012. The raise in water table may not be more than a meter duringmonsoon.

The layered deposit encountered in all bore hole are similar. The deposit appear to be homogeneous andisotropic, as N value at similar depth in various bore hole are same.

4.2 Systems of Rainwater Harvesting

Out of the various techniques adopted in India, and approved of by the Central Ground Water Authority, thefollowing are the three main classes of rainwater harvesting systems:

o System that collect direct roof runoff for storage and then reusing for various purposes.o Systems that use in-field or adjoining surface catchments to collect run-off and then impounded for

irrigation, horticultural, recreational & domestic purposes, after treatment.

36/133



o Systems that utilize the rainwater run-off from various surfaces including Terrace and Roads andgreen areas etc. for re-charging of the underground aquifer, through various measures.

In this system, the catchments from roof/terrace areas are further segregated for directrecharging of aquifer through filter media.

The catchment from surfaces of road/paved/park/lawns etc. is segregated and then taken to

underground, through desilting chamber/oil and grease separator etc.

4.3 Therefore as per prevailing practice and from a practical point of view in North India, it is morefeasible and recommended to use rainwater to recharge groundwater aquifers than for directstorage. Therefore, it is proposed to implement the system as explained in Point-C above, so as tomaximize the rain water utilization efficiency for recharging the underground aquifer.

The entire rainfall is received over a period of 27 days, 80% of which falls in the period between July toSeptember. The rainwater therefore has to be harvested during this short period.
