Fresh & Waste water Management

admin June 15, 2023 0

Objective:

Our primary goal is to ensure access to clean and safe drinking water for all township citizens while also promoting the recycling and reuse of wastewater. ELCITA aims to achieve a “Water Positive Township” status by 2030 through the implementation of integrated water management (IWM) initiatives.

Key Initiatives:

Freshwater:

ELCITA has been providing freshwater to its member companies since 2013. We source water from BWSSB and our own borewells, with a storage infrastructure of 1.5 MLD UGR and a 45HP pumping system. Currently, ELCITA receives 1.2 MLD of water from BWSSB and 0.15 MLD from borewells, distributing it to companies through pipelines and water tankers.

To optimize water usage, ELCITA has implemented a smart water system that integrates smart water meters, hydrostatic pressure transmitters, and Ion selective online quality monitoring systems with ELCITA’s I-Connect platform. Additionally, we have established a 100 KLD Softener system to treat hard water, ensuring it meets the BIS: 10500:2012 water quality standards.

As part of our commitment to sustainable practices, we have implemented rainwater recharge facilities throughout the township, resulting in 476.4 KLD of rainwater recharge and 120 KLD of harvesting potential. We also monitor the groundwater status through dedicated infrastructure.

Wastewater:

Given the size of the township, ELCITA has constructed multiple sewage treatment plants to collect and recycle sewage generated by industries. We have established STPs with a total capacity of 1925 KLD within Electronics City, utilizing different technologies such as Extended Aeration System, e-SBR, ABR & MBR, and SBT. As a result, ELCITA generates around 1600-1800 KLD of treated water per day.

To enhance operational efficiency, we have installed smart meters that are integrated with our i-Connect platform, enabling continuous monitoring of STP operations using an advanced SCADA system. As a result, our STPs achieve an impressive 95% efficiency and comply with KSPCB norms as per the “Water & Air (Prevention & Control) Act.”

State of the Art 1.6MLD MBR Plant

Recently, ELCITA completed the construction of a 1600 KLD “Membrane Bio Reactor” STP located at East Phase, Electronics City. The plant collects raw sewage from neighboring villages and companies through underground sewerage lines.

The MBR STP PLANT is equipped with high-energy efficiency electro-mechanical equipment and features an innovative acoustic wood system for blowers, ensuring noise levels are kept below 65 dB, which is 87% lower than the KSPCB limit. The plant utilizes a complete SCADA system for auto-operations.

Thanks to the membrane system, the treated water achieves high-quality standards, with an impressive sewage water treatment efficiency of 98%. Moreover, to ensure further purification, we have installed UV sterilizers that target and stabilize all biological impurities found in water.

Recycled Water

At ELCITA, we recognize the importance of water recycling. We utilize over 90% of treated water for non-domestic activities such as gardening, landscaping, construction, and road wash. Additionally, we sell recycled water to member companies for their landscaping and construction needs, further contributing to sustainable water management.

Enhanced Facilities

Our focus on maximizing water recycling and reuse allows us to use more than 90% of treated water for non-domestic activities like gardening, landscaping, and construction. Additionally, ELCITA supplies recycled water to member companies, supporting their landscaping and construction initiatives while fostering responsible water management practices.
