DIFFERENT KINDS OF RAIN WATER

HARVESTTNG STRUCTURES, DESTGNS

AND MODEL ESTIMATES

Rainwater harvesting (RWH) is a process of collecting, conveying, and storing the rainfall

in an area for the beneficial purposes. Considering the problems of water scarcity, pollution in

existing surface water bodies, and floods during rainy seasons in Karimnagar; the adoption of

rainwater haruesting practices is quite necessary and need of the hour. The methods involved

in this practice are simple and can be maintained at a minimal cost. Besides this, rainwater

harvesting is also very attractive because Karimnagar is having a good potential for harvesting

rains. Rainwater harvesting does not only improve the water usage practices, rather it is also

helpfut in the groundwater recharge. Considering the depletion of groundwater resources due

to excessive pumping of water, and its pollution from the leachate of waste dumping sites and

agricultural lands, replenishment of groundwater resources is also necessary. In view of this,

the present study focuses over the need, methods, detailed procedure for the establishment

of RWH system, and cost analysis for rainwater harvesting etc. The study also helps the people

to judge the best way to use the harvested water as per their need, geography of the area,

sub-surface geology, and prevailing local conditions. Along with this, some of the challenges

in the process have also been discussed at the end.

Water is one of the basic necessities of every living being for their suryival. Despite being

renewable, water is also a finite resource and therefore, needs extreme precautionary and

judicious use of it. Out of the total water available on the planet, only 3olo is fresh and can be

used for drinking purposes. However, the available fresh water is distributed very unevenly,

rendering serious implications on the steady supply across the globe. Moreover, with

increasing population, increasing urbanization, expanding agriculture, and rising standards of

living, tlre water demand has now touched a new arena, where it is getting difficult to meet

even the essentialities.

Natural replenishment of ground water reseruoir is a slow process and is often unable to keep

pace with the excessive and continued exploitation of ground water resources in various parts

of the city. This has resulted in declining ground water levels and depletion of ground water

resources in such areas. Artificial recharge efforts are basically, aimed at augmentation of the

natural movement of surface water into ground water reservoir through suitable civil

construction techniques. Such techniques interrelate and integrate the source water to ground

water reseruoir and are dependent on the hydrogeological situation of the area concerned.

Occurrence of rainfall in the city is mostly limited to about three months in a year. The natural

recharge to ground water reseryoir is restricted to this period only in a major part of thecity.Attificial recharge techniques aim at extending the recharge period in the post-monsoon

season for about three or more months, resulting in enhanced sustainability of ground water

sources during the lean season.

During the rainy seasons, it is often seen that roads get flooded while during the summers,

acute water shortage is faced by the dwellers. Although the cities receive good amount ofrainfall, still the problem of flooding during monsoon and droughts during summers has

become a very common phenomenon. This is because of the fact that the rainfall usually

occurs for short duration but with high intensity. Such conditions result in the heavy flow ofwater leaving very little amount for the recharge of groundwater. Thus, groundwater does notget chance to replenish

Considering this situation, the rainwater harvesting (RWH) technique has emerged as a boon.

Rainwater harvesting is a process of collecting, conveying, and storing the rainfall in an area

for the beneficial purposes. The collected rainwater can either be stored or it can be usedforrecharging the ground water depending on the needs and other factors. The collection of rains

can be done from rooftops, land surface, catchments/watersheds etc. using a number ofmethods. According to an estimate, for an average rainfall of 1000 mm, approximately 4million liters of rainwater can be collected in a year from an acre of land (i.e. 4046 m2).Therefore, in a city like Karimnagar which receives an appreciable amount of rainfall, adoption

of RWH technique may prove to be a savior.

Basically, the water harvesting methods can be classified into two:

3.3.1 Surface Run-Off Harvesting

During heavy downpour, the water flows away as sudace runoff. This runoff water can be

collected and used for recharging aquifers as shown in Figure 3-1.

3,3.2 Rooftop Harvesti*g

The amount of water harvested depends on the frequency and intensity of rainfall, catchment

characteristics, water demands, how much .u,ilff o..rrs and how quickly or how easy it is for

the water to infiltrate through the subsoil and percolate down to recharge the aquifers. In

urban areas, where adequate space for surface storage is not available and water levels are

deep enough to accommodate additional rainwater to recharge the aquifers, roof top

rainwater harvesting is the ideal solution to solve the water supply problems.

Though the concept of roof top rainwater harvesting is an age old one, systematic collection

and recharging to ground water is of recent times. Recent developments in the field ofhydrogeology especially in ground water exploration resutted in efficient and scientific design

of ground water recharge structures. As surface water sources fail to meet the rising demands

of water supply in urban areas, ground water reseryes are being tapped and over-exploited,

resulting in deciine in ground water levels and deterioration of ground water quality. This

precarious situation needs to be rectified by immediately recharging the depleted aquifers. In

urban areas, the roof top rainwater can be conserued and used for recharge of ground water.

This approach requires connecting the outlet pipe from rooftop to divert the water to either

existing wells/tube wells/borewell or specially designed wells. The urban housing complexes

or institutional buildings have large roof area and can be utilized for harvesting roof top

rainwater to recharge aquifer in urban areas. Table 3.1 shows availability of rainwater through

roof top rainwater harvesting.

In this system, the roof itself becomes the catchment and rainwater can be collected from the

roof of the house / building (Figure 3-1). The water can either be stored for utilization or itcan be divefted to an artificial recharge system. In this method, water can be collected without

much expense. This method is highly effective, and it can also help in the recharge of ground

water level.

Rainwater haruesting system includes the following components:

3.4.1 Catchments

The area or surface which receives the rainfall is known as catchment area for rainwater

haruesting (Figure 3-2). It may be rooftop, courlyard, open ground etc. In the simplest

method, rainwater is collected in vessels at the edge of the roof / open ground. Moreover,

gutters may also be used at some places which drain into the collection vessel with the use

of various pipes. Sometimes, the collected water is also passed through the settling tanks for

the suspension of settleable particles before the collection in storage tank for domestic use.

In rooftop catchment, the amount and quality of rainwater collected depends on the area and

type of roofing material. As per the Indian standard guidelines for rainwater harvesting,

rooftop water may be collected from roofs constructed with galvanized ironsheet, aluminium

sheet, deleterious glass fibre sheet asbestos cement sheets, tiles, and slates etc. Bamboo

gutters and thatched roof may also be used as rooftop material for the collection of water if

these are covered by waterproof sheeting like food grade low density polyethylene films. To

obtain the fresh quality of water, the roofs having metallic paint, or any other type of coating

should be avoided. The catchment area should also be cleaned on regular basis to remove

dust, leaves, and bird droppings so that water quality can be maintained. Only non-toxic paints

should be used in case the water has to be collected from painted roof. Moreover, water

collected from roofs painted with toxic materials should not be used for potable purposes.

If the catchment area is a land surface or ground, then water can be collected in reservoirs

using drainpipes. As compared to rooftop catchment, it is easier to collect rainwater fromthe

ground surface or open area. However, in ground surface catchment, there is the possibility

of water infiltration into the underground reservoir. Therefore, water collection after the rain

Source: Central Ground Water Board (CGWB)

should be irnmediate and sufficient measures sl'rould be taken to reduce the infiltration to the

ground.

3,4.2 Gutters (Drains) and Down take Pipes

Gutters and down take pipes are essential for taking up the water from catchment area to the

storage tanks as shown in figure 3.2. The materials to be used for gutters, as per the Indian

standard guidelines for rainwater harvesting, are galvanized iron sheet, wood, bamboo, or

reinforced cement concrete. For the construction of down take pipes, galvanized mild steel,

cast iron, and high-density polyethylene material may be used. The downpipe should be at

least 100 mm diameter with 20 mesh (850 p) nylon wire screen at the inlet in order to prevent

dry leaves and debris from entering into it [3, 4].

FIGURE 3-2 COMPONENTS OF MINWATER HARVESNNG SYSTEM

3.4.3 Filters and First Flush Devices

These devices remove grit, leaves, and dirt which are often found in the first rains. It is

necessary to remove these from the water as it may contaminate the whole water of the

storage tank. Sometimes, these devices are also useful when rains occur after a long time. In

such conditions, the rainwater carries with it, various dissolved pollutants. Materials such as

gravel, sand, or coconut, palm, or betelnut fibre, etc. may be used as filter media. Filters and

first flush diveft the water from the first rain to avoid mixing of it with the water of storage

tank (Figure 3.2).

3.4,4 Storage Tanks

These tanks might be either above ground or underground or partly underground as indicated

in figure 3.2. The tank should always be covered so that water should be clean. The storage

tanks may be made up of reinforced cement concrete, masonry etc. The size of the tank

depends upon factors like daily demand, duration of dry spell, catchment area, and rainfall.

Underground storage tanks should be suitably lined with water proofing material and

preferably have a hand pump installed for withdrawal of water. Their top should remain at

least 300 mm above the ground [3, 4]. Prior to the use of storage tan( it should be thoroughly

cleaned and disinfected using chlorine, bleaching powder, and potassium permanganate etc.

Measures to ensure the cleanliness of water can also be kept in the storage tanks for periodical

disinfection so as to prevent the growth of pathogens.

3.4.5 Delivery Systems

There should be efficient piping system which can deliver the stored water for the end use.

In the absence of any treatment, rainwater should be avoided for the consumption and

cooking. However, it can be used for other purposes. To be used for consumption,

conventional water treatment is necessary. Leaking and rusted pipes should be avoided

completely. To avoid any leakage, timely check-up of the pipes is necessary.

3.4.6 Recharge Structures

Haruested rainwater can also be used for charging the ground water aquifers through the

construction of various kinds of structures like dug wells, borewells, recharge trenches, and

recharge pits (Figure 3.2). There may be different depths in recharge structures, such as

depth can be such that water reaches to lower soil strata. Examples of such structures are

recharge trenches, permeable pavements etc. In other case, the depth of the pipe down in

.;

the soil can be such that it reaches to the level of ground water and joins it. Examples of these

kinds of structures are recharge wells. Nevertheless, for recharging the groundwater aquifers,

the possibility of contamination from nearby areas should be thoroughly checked and

accordingly changes may be made in the designing'

On an average, Karimnagar town receives around 907 mm rainfall in a year out of which' 80

- gao/ois received only during monsoons. Even though rainwater is the only major source of

Karimnagar town water need, its collection and significance is highly neglected in Karimnagar'

Although the total amount of rain which is falling on the earth cannot be collected due to

evaporation losses, spillage etc., but still a fair amount of it can be put into use' The total

amount of water that is received in the form of rainfall over an area is called the rainwater

endowment of that area. However, out of this, the amount which can be effectively

harvested is actually called as the rainwater haruesting potential' In urban areas where

the open grounds are scarce, rooftop rainwater harvesting is suitable option whereas in rural

areas and outskirts of the city, surface runoff or a combination of both the methods may be

used.

Rainwater harvesting has several advantages as given below:

i. In areas where there is inadequate groundwater supply or suface resources are either

lacking or insufficient, rainwater harvesting offers an ideal solution'

ii. Rainwater is bacteriologically pure'

iii. It is free from organic matter and soft in nature'

iv. it will help in reducing the flood hazard'

v. It improves the quality of existing ground water and helps to replenish it'

vi. It reduces the cost for pumping of ground water'

vii.

It helps to meet the needs of already water scarce society.

It also reduces soil erosion in urban areas.

No land gets wasted for RWH and hence there is no issue of population displacement.

Rainwater may be harnessed at place of need and utilized at the time of need.

The structures required are simple, economical, and eco-friendly.

The technique does not require rigorous manpower,

It helps in utilizing the primary source of water and prevents the runoff from going

into sewer or storm drains, thereby reducing the unnecessary load on treatment plants.

Adoption of rooftop rainwater harvesting followed by its storage through artificial recharge

methods at household level could be a viable strategy to locally tackle the growing water

scarcity problem that is prevalent in most of the towns and cities of India. Artificial

groundwater recharge methods can be adopted in urban areas where:

Groundwater level occurs at a depth of 5m or more;

Permeable strata are available at shallow or moderate depth;

Groundwater quality needs improvement;

There are possibilities of saline water intrusion in coastal areas; and

Evaporation rate from surface storage will be very high.

The AR techniques described in the previous section are more suitable for large-scale RWH

projects with huge catchment area. They may also be appropriate for institutional campuses

with Large rooftop as well as open suface area. Many simple and low-cost AR techniques

have been developed and practiced to encourage households to adopt RWH practice. The

methods prescribed for adoption at household levels are mostly the simplified forms of the AR

techniques described earlier. These include:

3.7.1 Abandoned or in-use dug wells: -

Dry and unused or in-use weils in the buildings can be used as rainwater recharge structure

(Figure 3-3). If abandoned well is to be used, it is essential to clean the bottom surface of all

fine deposits. The rooftop rainwater has to be guided through a pipe to the bottom of the well

or below the water level to avoid scouring of the bottom and entrapment of air bubbles in the

aquifer. It is preferable to make the collected rainwater silt-free by passing it through a silt

trap (gully trap) before recharge. Periodic chlorination is recommended to avoid bacteriological

contamination.

3.7.2 Abandoned or in-use hand pumps:

In this case, hand pump (abandoned or in-use) is adopted as the rainwater recharge structure.

The rooftop rainwater is diverted to the suction pipe of the hand pump through a small

diameter pipe (50 mm or 100 mm) as shown in Figure 3-4. A gate valve would require to be

fitted with the rainwater conveyance system to avoid entry of air into the suction pipe. A small

collection tank in the rainwater conveyance system can act as silt trap as well as a balancing

tank. During recharging period (rainy days), the water extracted from the hand pump should

be used after boiling or chlorination.

and 2 to 3 m deep. The pits can be of any shape, i.e. circular, rectangular or square' After

excavation, the pits are refilled with coarse gravel, pebbles and boulders' The fillings can

function as a roughing filter to remove suspended impurities, if any, in the collected rainwater'

3.s.i Alternative-I, Conventional Rainwater Harvesting System :

For assessment of quantity of rainwater that can be harvested, estimation of roof catchment

area and the rainfall are required.

Total roof catchment area = A m2

From data published by the Meteorological Department of India, the annual average rainfall

in Karimnagar has been adopted as 907 mm.

The total quantity of rainwater that can be harvested annually is = Catchment area X Annual

rainfall X Runoff coefficient

For the design of aftificial recharge system, critical rainfall scenario has to be considered. The

rainfall data of Karimnagar over the previous decades indicates that on an average, there are

27 rainy days in a year. However, about 75o/o of the rains occur within a period of three

months (july - September), with maximum rainfall during the month of July, which accounts

for 30% of total annual rainfall. Even during the rainy months, rainfall may be occurrlng only

for a few days.

For the purpose of assessment of critical rainfall scenario, it has been assumed that out of 27

rainy days in a year, the number of rainy days in the critical month of July will be in the same

proportion as the quantum of rainfall during the month, That is, 30o/o of the27 rainy days will

fall in the month of July. With this assumption, the (maximum) quantity of rainwater that will

be harvested and utilized for groundwater recharge during the critical month been calculated

as below:

(i) Average rainfall during the month the month of July = 3Oo/o X 907 = 272mm

(ii) No of rainy day in July

(iii) Critical rainfall per day (with safety factor 2)

= 30o/o X 27 =8 days

= (27218)X2 = 68 mm

(iv) Maximum quantity of rainwater haruested in a rainy day of July

=Catchment area X rainfall X 0.9

Because of the highly permeable, alluvial soil strata, a gravel filled artificial recharge pit

combined with two no's of gravity-fed injection bores has been envisaged as the recharge

structure for Karimnagar city. The details of the recharge system installed are schematically

presented in Figure 3-7.

The recharge pit has been filled with four layers, top layer is kept empty for standing water

to create the head on water, the layer below the standing water filled with coarse sand of

size 1.5-2.0 mm with 35o/o porosity, layer below the sand is filled with gravels of size 5-10 mm

with 30% porosity and bottom layer with boulders of size 5-20 cm with 30o/o voids, which acts

also as a roughing filter to effect primary level treatment to the collected rainwater before

recharge.

The depth of standing water above sand bed is considered 1,0 m, the depth of coarse sand

below the standing water is 0.5 m, the depth of gravel bed below the sand bed is 0.5 m,and

the depth of boulders below gravel bed is 0.5 m.

The equivalent liquid depth in the trench

1+ (0.5 x 0.35) m + (0.5 x 0.3) m +(0.5 x 0.3) m

= L.475 m

Therefore, Area of the trench required for spreading =Volume of rainwater / liquid depth

Based on the area available at the location selected for the recharge pit, the size of the trench

shall be fixed as L m x B m x D m.

Additional area requirement has been offset by providing two gravity fed injection bore well

of 0.20 m diameter. The bore well is encased with slotted PVC pipes of 0.15 m diameter for

structural support and prevention of clogging. The depth of the bore well is 10.0 m at which

level groundwater table found in this area.

The injection bores will increase the recharge capacity of the trench by about 50o/o. The

additional recharge capacity so obtained can take care of abnormal exigencies, and any future

expansion of catchment area. By ensuring faster rate of infiltration, the injection wells will also

help minimize evaporation losses of the harvested rainwater.

Design parameters for setdement tank:

settlement tanks are used to remove silt and other floating impurities from rainwater.Settlement tank is like an ordinary container having provision for in flow, outflow and overflow.Settlernent tank can have an unpaved bottom suface to altow standing water to percolateinto the soil' Apart from removing silt from water the desilting chamber acts like a buffer inthe system.

For designing the optimum capacity of the tank following aspects have to be considered:

i. Size of catchment

ii. Intensity of rainfall

iii. Rate of recharge

Since the desilting tank also acts as buffer tank, it is designed such that it can retain a certainamount of rainfall, since the rate of recharge may not be comparable with the rate of runoff.The capacity of the tank should be enough to retain the runoff occurring from the conditionsof peak rainfall intensity. In Karimnagar Peak hourly rainfall is 46 mm. The rate of rechargein comparison to run off is a critical factor. However, since accurate recharge rate are notavailable without detailed Geo-hydrological studies. The rates have to beassumed.

The roof top catchment area available for rainwater collection at Gps-URDHU-MUKHRAMpuRAschool has been calculated from the building plan drawing as given in Figure 3-9. The capacityof the recharge tank is designed to retain runoff for at least 30 minutes of rainfall of the peakintensity (for Karimnagar 23 mm per 30 minutes)

The data for a Govt School

Surface area of the Roof Catchment (A) = 340 Sq.m

Peak rainfall in 30 min (r)

Runoff co-efficient (C)

=23mm

= 0.85

Capacity oftank = A x rx C = 340 x 0.023 x 0.g5 = 7 cum

Assume Capacity of tank is 10 cum = 10,000 Liters.

Typical drawing of the new rainwater harvesting structure and its section are given in Figure

a

3-9 and Figure 3-10. schematic layout of rainwater routing to RVIHS for Govt Schools is

given in Figure 3-11.
