Chennai Metropolitan Water Supply & Sewerage Board - Head Office

Chennai Metropolitan Water Supply and Sewerage Board, known shortly as CMWSSB, provides water supply and sewage treatment to the city of Chennai and areas around it.Chennai is one of the metros in India which is dependent mostly on ground water supply. Ground water in Chennai is replenished by rain water and average rainfall in Chennai is 1276 mm. Chennai receives about 985 million liters per day (mld) from various sources against the required amount of 1200 mld and the demand is expected to rise to 2100 mld by 2031. The newly constructed Minjur desalination plant adds another 100 mlds to the city's growing demand. As of 2012, Chennai Metrowater supplies about 830 million litres of water every day to residents and commercial establishments. Till about the mid of 19th century, Chennai received water from local shallow wells and tanks. Mr. Fraser, a civil engineer who visited Madras, forwarded a proposal to the government to tap the Kortalayar river which is situated about 160 km northwest of Chennai and it was accepted. The project consisted of a masonry weir across Kortalayar at Tamarapakkam and diverted the water into Cholavaram lake and hence into the Red Hills lake through a channel. The works were completed in 1870 at a cost of about Rs.18.50 lakhs. In 1872, a Valve House at Red Hills and an earthen supply channel to supply water to Chennai by gravitation was constructed. In early 1890, surface drains in the City were connected to Pumping Stations and the wastewater conveyed for disposal away from inhabitation. The authorities observed an increase in population in the beginning of the 20th century. Hence, they decided to develop a comprehensive drainage scheme. The proposal for this scheme to cater to the needs of a topographically flat, fast growing city was formulated in 1907 and works were initiated in 1910 and completed during 1914 in stages. The systems were designed for the population of 6.5 lakhs expected in 1961 at 114 lit. per capita per day of water supply. The system originally consisted of a network of force mains and brick gravity sewers served by 3 Pumping Stations at Royapuram, Purasaiwalkam and Napier Park and ultimately discharging wastewater into the sea at Kasimedu on the Northeastern boundary of the City. A fundamental change to this system was made in 1956 by laying a force main to divert part of the sewage discharged from the Purasaiwalkam Pumping Station to Kodungaiyur where the sewage farm was established. The aim of this diversion was to utilise the sewage for irrigation and fertilising agricultural land. But one of the implied benefit of this was the conservation of fresh water whose supply was scarce. Thereafter a comprehensive wastewater management scheme was formulated. The implementation of these schemes commenced in 1961 and had undergone modifications periodically commensurate with the system requirements of an expanding City and the growing population. The wastewater system for the City has been divided into five drainage zones. These zones of macro systems covering the entire City had independent zonal collections, conveyance, treatment and disposal facilities. Zone-1 covers the areas of Tondaiarpet, Washermenpet, Royapuram, George Town and Chindadripet. Zone-2 comprises areas such as Nungambakkam, Chetpet, Kilpauk, Egmore, Purasaiwalkam, Ayanavaram, Perambur, Vyasarpadi, Sembium, Kolathur, Periyar Nagar, Jawahar Nagar and Kodungaiyur. It is the largest of all zones. Zone-III lies between Zone-II and Zone-IV to the West. It comprises Thyagaraya Nagar, Kodambakkam, Arumbakkam, Anna Nagar and Koyambedu. The areas covered by Zone-4 are Ashok Nagar, Saidapet, Jafferkhanpet, K.K. Nagar and Nesapakkam. Zone-V is the second largest of the five macro systems and is to the South of the City which is bifurcated by the Adyar River. Areas covered are Ice House, Mylapore, Adyar, Guindy, Velacherry, Gandhi Nagar and Indra Nagar. Therefore, considerable amount of efforts were made by the government to ensure the administration and development of a proper wastewater system in Chennai.

The Chennai Metropolitan Water Supply and Sewerage Board (CMWSSB), often referred to as Chennai Metro Water, plays a crucial role in managing the water and sewage systems in one of India's largest and most densely populated cities. 1. Comprehensive Water Supply Management Reliable supply: CMWSSB provides drinking water to a large portion of Chennai through a piped network, tankers, and hand pumps. Desalination Plants: Operates major desalination plants (Minjur, Nemmeli) to reduce dependency on unpredictable monsoon rainfall. 2. Technological Integration Online services: CMWSSB has improved digital services like online bill payment, grievance redressal, water tanker booking, and mobile apps. Smart metering and SCADA systems: Some areas use smart meters and real-time monitoring for efficient water distribution and pressure management. 3. Sewage Management and Treatment Operates several Sewage Treatment Plants (STPs) to treat wastewater before it is released or reused. Promotes wastewater recycling and reuse, especially for industrial and construction purposes. 4. Rainwater Harvesting Advocacy CMWSSB has been a strong proponent of rainwater harvesting (RWH). Chennai was one of the first major cities in India to mandate RWH in buildings. This has contributed to groundwater recharge and reduced water stress. 5. Emergency and Drought Management During water crises (like the 2019 shortage), CMWSSB coordinated water tankers, rail supply (Jolarpettai project), and sourced water from alternative locations to meet basic needs. Shows resilience and adaptability in challenging circumstances. 6. Community Engagement and Public Awareness Runs awareness campaigns about water conservation and hygiene. Encourages public participation in initiatives like "adopt a water body" and neighborhood water audits. 7. Infrastructure Development Ongoing investments in expanding the sewer network, upgrading aging pipelines, and reducing non-revenue water (NRW). Part of AMRUT and Smart City missions for urban water infrastructure enhancement. Thanks Bharathidasan M
