Sewage Water Treatment

Wastewater treatment plants operate in the Main campus (300 KLD) and MIT Campus (200 KLD). Due to an increase in the students' strength, the quantum of wastewater generated is rising. A 300 KLD treatment plant with an ultra-filtration facility and back washing arrangement in the students’ hostels is nearing completion in the main campus. A similar facility with 200 KLD capacities is under construction at MIT campus. In addition, a 200 KLD treatment plant is under construction in the Main campus, and it is planned to use the treated water for gardening purposes.

An average of 9 lakh litres/day and 4 lakh litres/day of wastewater is generated from various parts of the Main and MIT campus to the Sewage Treatment and Recycling plant, which can treat 9 lakh litres of water per day. The treated wastewater irrigates lawns and gardens through Sprinkler Irrigation Systems. The wastewater from the kitchen is used for the in-house vegetable garden. It is also proposed to modernize the existing Sewage Treatment Recycling Plant to improve the treated water quality standards for flushing toilets in the new buildings.

Solar Energy

Power generation by solar energy and energy conservation

Solar power of nearly 105 kW is generated in Anna University Main campus, the CUIC, Centre for Excellence building, AU-FRG-ICC, and Thamarai Hostels, and in MIT campus, the Lecture Hall Complex and Marutham Hostels.

A proposal for generating a 500kW solar panel in the main campus has been approved in the Syndicate, and tender work is underway.

A Campus wide network load monitoring system (45 net meters installed in various buildings) is established. This setup is useful for monitoring continuous energy consumption and, intern to initiate energy conservation measures.

The street lamps in the four campuses have been converted to LED lamps. Nearly 75% of the street lamps on the campuses are LED lamps, and 25% of internal lighting on the campuses is through LED bulbs. All the air conditioners installed in the Departments follow the energy conservation policy (5-Star Quality Rating System).

Sensor-based on-and-off switching of the streetlamps on the campus has been implemented.

Renewable based power generation using SPV Power Plants

Solar Power Plants aggregating to 85kW had been installed by IES at rooftop of Thermal Sciences Building and Centre for Excellence building. These SPV plants are able to replace about 1.4 lakh units of electricity sourced from TANGEDCO and mitigate about 167 tons of associated CO2 emissions every year.

SPV Power Plants

Solar Power street lighting Systems

219 street lights installed at CEG and MIT campus are powered exclusively using SPV systems. 74 numbers of 330 Wp solar panels aggregating to 24 kW capacity were installed to provide the power supply to these street lights.

Installation of Smart Meter Network and Monitoring System for energy monitoring and targeting

Network load monitoring meters (50 Nos.) is installed at 50 different buildings in Anna University. All 50 meters installed in the campus transfers data to a centralized server through wireless data connection. Various electrical parameters are remotely monitored and used later for load analysis, forecasting or energy audit. Network load monitoring systems is used for monitoring electricity consumption pattern in a building and for load analysis. It is very useful during load forecasting and load scheduling. Depending on the load, energy requirement in a building can be planned. It is also useful in planning the capacity and installing renewable energy-based power generation system.

Net Zero Solid Waste

Bio Gas Power Plant

Disposal of food and vegetable waste from hostel mess has been an perennial issue for the hostel administration. These wastes are generated in large quantities (around 1 ton per day). Hostel mess is using about 600 commercial LPG cylinders per month for cooking. A biogas plant of 1 Ton capacity has been installed towards utilisation of these food/vegetable waste for biogas generation to reduce the dependence of LPG. Residues from the biogas plants is being utilised as a manure for organic farming.

One TPD capacity biogas plant - 1000 kg/day (6 m3 gas holder)

Bio- Fertilizers

The organic wet waste from hostel kitchens, mess, and canteen is sent to the biogas plant. The gas generated is used for cooking purposes at the hostel kitchens, and the slurry generated is used as fertilizer in the organic farm at the campuses

Organic waste is decomposed naturally by storing it in pits, and it is converted into manure

Bio Diversity of Anna University

Anna University was established in 1978 through Tamil Nadu Act 30 of 1978. The main Anna University Campus is in Guindy sprawling 185 acres which supports its own flora and fauna. AUC is blessed with a large number of beautiful and exquisite wild trees which are native to the dry, evergreen forest type that exist here. It is estimated that there are more than 500 species of plants expected in this campus. There are quite a number of exotic species of trees that are introduced for horticultural purpose over a period of time. Trees also play a major role in supporting a large number of birds, insects, animals etc. for food and habitat requirements.

These university campuses shelter native biodiversity within cities are fundamentally ecological landmasses. By and large, the suburbs of south Chennai have sustained some of the leftovers of breathing habitats that characterize north-eastern Tamil Nadu in general. The Anna University, Guindy National Park, Raj Bhavan and Indian Institute of Technology complex has historically enjoyed a certain degree of protection and hence has continued to support a large amount biodiversity. The Guindy National Park is a Protected Area, while the Raj Bhavan Complex is a high security area thereby allowing only very restricted presence of humans. This ensures that the biodiversity in both these areas is conserved in a rather insulated manner. In contrast, the continuous presence of humans on the campus of Anna University and Indian Institute of Technology has warranted a conservation plan with management goals.
