Challenges to Wastewater treatment in India

India is struggling with water scarcity like no other nation and the picture of the future doesn’t look good. It is imperative that we pay attention to this problem and take wastewater treatment more seriously than ever. Water treatment companies in India like Sauber Environmental Solutions are committed to helping the nation overcome this problem.

Since India is currently an economy that is in transition from being a developing nation to a developed nation, the country is majorly facing two problems – on one end there is lack of infrastructure while on the other end the country is witnessing constant rise in the urban population. Public services have not been able to keep pace with rapid urbanization. Water supply, sanitation measures, and management of sewage cover only a part of the total urban population.

Easier said than done! Follow 3 R’s Principle – REDUCE, RECYCLE & REUSE

Here’re a few challenges to wastewater treatment in India-

Wastewater Generation and Treatment: According to an estimation, about 38,254 million litres of wastewater per day (mld) is generated in the urban centres which comprises of Class I cities and Class II towns having the population of more than 50,000 (which accounts for more than 70% of the total urban population). The municipal wastewater treatment capacity developed so far is about 11,787 mld, that is about 31 per cent of wastewater generation in these two classes of urban centres. Majority of wastewater treatment plants are out of order

due to lack of maintenance. The untreated wastewater also pollutes the existing water sources, only to add to the problem even more. Considering the population of India, ignoring the wastewater treatment issue isn’t an option anymore.

Industrial and population growth: Growing population has increased the need for power generation, for example, which placed greater demands on water reuse.

Fresh water costs: The cost of clean, fresh water is continually increasing, and is impacting all Businesses, Societies, Communities

Regulatory requirements: Industrial sites have nowadays very stringent wastewater discharge permits that include flow and quality restrictions. Moreover, CPCB/SPCB Industrial Effluent Guidelines are often revised. Now, more demands and regulatory focus is on Zero Liquid Discharge (ZLD) for Industrial units.

Water scarcity: Many regions in India are susceptible to drought. Natural Ground water table is depleting in rapid pace. Additionally, some industrial plants have limited access to clean/fresh water.

Power costs: In many industries, electricity cost is quite significant and they put efforts to enhance the power consumption efficiencies by utilising various options of ‘Waste to Energy’ technologies

Land Scarcity: In today’s urban India, land availability is a major concern and always drives the companies for modern space saving technologies for their waste water solutions.

Sustainability efforts: Many companies strive towards sustainability by utilizing economically sound programs that help minimize a plant’s negative environmental impact while conserving energy and natural resources.

Sewage Recycling Project Reference:

M/s Rashtriya Chemical and Fertilizers Limited (RCF) & M/s Bharat Petrochemicals Corporation Limited (BPCL) joined hands with the Municipal Corporation of Greater Mumbai (MCGM) to set up the ‘Waste Water Recycling Sewage Treatment Plant.’ The purpose of the project was to save the most precious gift of the nature “fresh potable water”.

We at Sauber provided complete design engineering support and PMC to EPC Contractor, M/s SMC Infra Pvt Ltd, Mumbai, for 22.75 MLD SEWAGE RECYCLING PLANT FOR M/S. RASHTRIYA CHEMICALS AND FERTILIZERS LIMITED (RCF),

TROMBAY, MUMBAI by using state of the art technologies i,e Membrane Bio Reactor followed by Reverse Osmosis System. This plant was commissioned in June 2019. The treated water of 15 MLD RO permeate is used by M/s. RCF & M/s. BPCL for meeting their industrial manufacturing needs thus addressing several of their key drivers like freshwater cost, regulatory requirement, discharge costs, water scarcity and above all sustainability.

Project Major Components:

1. 5 MLD Sewage Pumping Station (SPS) in the premises of Municipal Corporation of Greater Mumbai (MCGM).
2. 75 MLD capacity Fully Automated Sewage Recycling Plant based on Membrane Bio-Reactor (MBR) Technology followed by Reverse Osmosis (RO) to generate 15 MLD of treated water at RCF Plant, Trombay.
3. 15 MLD Treated water pumping station with treated water pumps for treated water supply to M/s. RCF & M/s
4. 800 mm diameter – 4.5 Km DI K9 Raw sewage pumping main, 500 mm diameter- 1.5 km clear water pumping main for RCF & 300 mm diameter- 4 km treated water pumping main for
