| Rainwater Harvesting |
| We have been harvesting rainwater for a few years and the results have been very encouraging. During the reporting year we extended the initiative to cover two more facilities - API Nalgonda Plant and CTO SEZ. |
| We harvested 194,600 kilolitres of rainwater across units - API Hyderabad Plant 4, API Nalgonda Plant, API Srikakulam Plant, CTO SEZ, Formulations Hyderabad Plant 1, 2, 3, Formulations Baddi Plant 1. |
| Rainwater Harvested in
API Plants BU |
| API plants business units consumes 689,000 kilolitres of fresh water per annum. In FY15, 122,000 kl of rainwater was harvested due to which the unit reduced the usage of total fresh water by 17.7%. |

A 3.5 km storm water drainage system was
constructed within the plant |

Two storm water collection tanks of capacities
1,000 kl each were constructed |
| |
Two storm water drains were laid to collect
and transfer all the storm water from the site into
the collection tanks. |
| |
The storm water was further treated to make it fit for
consumption in utilities and the reject was sent to
multiple effect evaporators. |
API
Srikakulam
Plant |
|
Three tanks of a total capacity 160 kl were used for
collection of storm water. |
|

| |
The storm water collected was pumped into 800 kl capacity rainwater storage tanks using higher capacity pumps. |
| |
The rainwater was used in cooling towers after passing it through the reverse osmosis system. |
| CTO SEZ |
|
A well thought-out plan was devised for rainwater harvesting |
|
81,000 |
| |
Measures were taken to impound maximum quantity of run-off water generated in the area and backwater coming through the adjacent streams. |
| |
A total of six rainwater harvesting pits, one large irrigation tank spread over 33 acres, an open well and a storage cum percolation pond were constructed |

Rainwater Harvested in the
Formulations Business Unit |
| The Formulations BU consumes 450,000 kl of fresh water per annum. In FY15, 72,000 kl of rainwater was harvested due to which the unit reduced its fresh water usage by 16%. |

| Technical feasibility of rainwater harvesting at Formulations Vizag SEZ Plant, FTO 9, Baddi Plant 2 & FTO SEZ sites is on
the anvil |
| Budhera (Zaheerabad) - Technical feasibility is being carried out |
| Technical feasibility & possibility of implementing rainwater harvesting in hilly areas of Telangana and Andhra Pradesh is being evaluated |
