Scheme :: ROOFTOP RAINWATER HARVESTING & GROUND WATER RECHARGE

IN URBAN AREAS OF ODISHA

1. Introduction to the scheme

Ground water is one of the most important natural resources, which has a very wide spatial distribution. It serves as a major source of domestic water across the State. As per the water supply and demand status (2012-13) in Urban Local Bodies (ULB), ground water plays an important role. Ground water constitutes about 40% of the total public water supply. Apart from the public supply systems, large numbers of private wells serves as only source of water or many households in these areas.

Due to rapid urbanization, the scope of natural ground water recharge is being reduced day by day. 

Other Schemes

 Such a situation will eventually lead to water table depression and water quality degradation. Rainwater conservation and ground water recharge practices are essentially required to be adopted for sustainable ground water management in these areas. Many cities like Chennai, Pune, Bangalore , Delhi etc have already adopted such practices to combat water scarcity as well as water quality issues.  

Department of Water Resources (DoWR), Govt. of Odisha, intend to launch a new   State Sector Scheme, during FY-2014-15  for rainwater conservation and ground water recharge through adoption of Rooftop Rainwater Harvesting Systems (RRHS) in private and Govt. buildings in all ULB of the State. The Scheme is to be launched on pilot basis, within the urban local areas of Bhubaneswar , Berhampur, Titilagarh, Bolangir and Jharsuguda. Subsequently, towns facing acute shortage of drinking water will also be covered.  The Scheme is very eco-friendly and does not require any land acquisition or displacement of people.

2.     Objectives

The important objectives of the Scheme are to augment ground water recharge, improve water table and water quality conditions in all urban areas (ULB) of the State through mass adoption of RRHS in private buildings as well as in Govt. buildings. 

 

3.       Salient Features of Scheme

(a) Building owners shall choose any one out of the nine RRHS Models specified below , based on the water requirements and space for execution of different components. Initially building owners shall construct the RRHS at their own cost.

(b)  The actual cost of a Rooftop Rainwater Harvesting System (RRHS) may vary from building to building depending on the water requirements, type and size of roof, Model of RRHS adopted etc. The typical cost estimate for a building having roof area less than 200 Sqm with different Models of RRHS, which includes cost of following four major components of RRHS.

1.     Rainwater Collection Unit - PVC (110-150 mm) pipeline with fittings for rooftop rainwater collection and conveyance to different units.

2.     Filter Unit - Masonry tank with a bed of filter materials.

3.     Storage Unit - RCC underground rainwater tank of 5,000 - 10,000 liters capacity

4.     Recharge Unit - Dug Well / Bore Well / Tube Well with depth range of 10-50 m.

(c)   In case any or all of the four components such as dug well or bore well or tube well, water storage tank or sump and roof water drain pipes exist in the building premises, the same can be suitably modified to be incorporated into the RRHS.

(d)  The RRHS should have a suitable recharge unit (well), which is compulsory under the Scheme for claim of subsidy. The modular PVC / HDPE Filter Unit or Storage Unit available in the market can also be used in place of such units made of RCC or ferro-cement or masonry. 

(e)  The typical cost estimates of four major components of RRHS have been indicated below .The cost of RRHS shall be evaluated considering the actual investment made by the owner for the different components as described above. The cost of existing components, if any, can be considered for such evaluation under the Scheme. After successful testing of the RRHS by the authorized officer, a Certificate of Fitness shall be issued by GWS&I.

(f)    The State Government shall release 50% of the cost investment actually made (limited to the cost of adopted model) by the building owner or Rs. 45000/- whichever is less, as subsidy through GWS&I.

(g)  Any person, owning a building having a roof area less than 200 Sqm and not having more than three floors will be eligible to apply under the Scheme. The building owner at the time of submitting application shall have to attach the proof of his ownership (copy of holding tax / land revenue receipt / ROR etc).

(h)  Non-residential and residential Govt. buildings (in urban / rural areas) shall also be covered under the Scheme in a phased manner. The total cost of the installation of RRHS in these buildings shall be met from the budgetary allocation under the Scheme.  

(i)  The Scheme envisages covering 550 Govt. and 16405 private buildings within a period of five years at an estimated cost of Rs. 100 Crore. In urban areas private buildings having roof area less than 200 Sqm (2150 Sft) and not having more than three floors will be eligible to be covered under the Scheme. There is a provision for payment of subsidy to owners of such private buildings up to Rs. 45000/- for adoption of the RRHS.

4.       Present Status of the Scheme                                                                                                                

In the first phase following five water stressed towns(Sl. 1 to 5) have been taken up under the Scheme.Later on during the FY 2018-19 ,06 more no. of towns have been added under this scheme. The year-wise cumulative physical and financial achievements made since FY 2014-15 up to end of April 2018 (FY 2018-19) are indicated below.
