The Delhi Development Authority (DDA) has unveiled plans to install automated real-time monitoring systems for sewage treatment plants (STPs) that supply treated water to almost 100 public parks across the city. The initiative aims to enhance the quality and reliability of treated wastewater used for irrigation and greenery maintenance, reducing dependence on manual checks and improving oversight of critical water-treatment parameters. Systems will continuously track indicators such as biochemical oxygen demand, chemical oxygen demand, total suspended solids, pH and treated water output, officials said. The authority has invited expressions of interest for the project, with bids expected from firms capable of deploying modern wastewater treatment technologies. The parks involved span multiple localities, and plant capacities range from small to medium-sized units. The move is designed to bolster park maintenance and support environmental goals by ensuring consistent and high-quality treated water is available for landscaping and public use.
The Delhi Development Authority has announced a new initiative to install automated, real-time monitoring systems for sewage treatment plants (STPs) serving nearly 100 parks across the national capital. The authority said the move is intended to strengthen oversight, improve water quality and enhance the upkeep of green spaces by ensuring treated wastewater meets established standards at all times.

Under the plan, the automated systems will continuously monitor key operational parameters at STPs, including biochemical oxygen demand (BOD), chemical oxygen demand (COD), total suspended solids (TSS), pH levels and the volume of treated water produced. These indicators are critical for assessing the effectiveness of treatment processes and ensuring that water used for irrigation and maintenance of park landscapes is of suitable quality. The real-time data will reduce reliance on manual checks, which have traditionally been subject to delays and potential inaccuracies, and will allow the authority to respond more quickly to performance issues.
Parks identified for the initiative include sites in Dayanand Vihar, Vivek Vihar, Ashoka Niketan, Ashok Vihar, Shalimar Bagh and Narela, among others. The STPs at these locations vary in capacity, ranging from around 10 KLD (kilolitres per day) to 250 KLD, reflecting a mix of small and medium plants that support irrigation needs for landscaped areas within park boundaries.
DDA has invited expressions of interest from firms to undertake the installation of the monitoring systems and to maintain them, signalling the start of the procurement process. The tender documents mandate the use of modern wastewater treatment technologies, particularly for plants with smaller capacities up to 100 KLD. Officials said that integrating advanced treatment and monitoring solutions will help ensure consistent reuse of treated water and minimise environmental risks associated with underperforming plants.
By adopting real-time monitoring, the authority expects to reduce human error, improve transparency in STP performance reporting and enhance the maintenance of greenery in public parks. The initiative aligns with broader environmental and water management goals as authorities seek to improve the efficiency of treated wastewater use and support sustainable urban landscaping across Delhi.
