Haridwar strengthens Ganga cleanliness with advanced sewage treatment
Haridwar (Uttarakhand) [India], July 7 (ANI): Haridwar, one of the holiest cities in India and a key site of the Kumbh Mela, is making major strides in preserving the purity of the river Ganga through enhanced sewage treatment infrastructure under the Namami Gange Mission. Working towards the goal of a clean and rejuvenated Ganga, the city now hosts two state-of-the-art Sewage Treatment Plants (STPs) with a combined capacity of 82 million litres per day (MLD). These include a 68 MLD STP at Jagjeetpur and a 14 MLD STP in the Sarai area. With these additions, Haridwar's total sewage treatment capacity now stands at 145 MLD, operating at peak efficiency. The Jagjeetpur STP, based on Sequential Batch Reactor (SBR) technology, is the largest in Uttarakhand and holds the distinction of being India's first STP under the Hybrid Annuity Model. It is also the country's first 'Pink STP', with 50 per cent of its staff comprising women, promoting gender inclusivity in environmental management. 'Earlier, all domestic waste used to flow directly into the Ganga. The biggest achievement of our plant is that we are now able to treat all the sewage generated by our community effectively,' said Manoj Kumar Verma, in-charge of the Jagjeetpur STP. Similarly, the 14 MLD STP in Sarai is effectively treating sewage using modern techniques. The treated water is being reused for irrigation, benefiting the local agricultural community and helping to mitigate groundwater depletion. Sandeep Rathore, a local farmer, said that the change in groundwater is noticeable. 'The water from this STP is being used for irrigation, and the difference compared to groundwater is clearly noticeable. Crops irrigated with this treated water grow much better. The nutrient content and overall quality of the water are excellent; it truly nourishes the crops,' Rathore said. These advanced facilities are future-ready, equipped to manage rising waste volumes stemming from the city's growing population and the increasing influx of pilgrims during major festivals such as the Char Dham Yatra. These initiatives mark important milestones under the Namami Gange Mission, launched by the Government of India to restore the Ganga to its pristine form. Apart from pollution abatement, the mission also aims to protect the religious, cultural, and ecological significance of riverside cities, such as Haridwar. The progress in Haridwar reflects the collective commitment of stakeholders towards sustainable development and river conservation. (ANI)

Essex's wastewater treatment facilities to require $11M over next five-years
Essex Council received a report regarding the condition and operational capacity of the Town's wastewater treatment facilities for information during the April 22 meeting. Through the report, members of Essex Council learned that between the municipality's four wastewater treatment plants, around $11M in capital expenses will be required over the next five-years. Rob Mackie, Manager of Environmental Services, created and presented the report, as Council directed Administration to provide a high-level report on the condition and operational capacity of the Town's sanitary treatment facilities back in February. 'All in all, our treatment facilities still have a significant portion of capacity available to service our communities,' Mackie told Council. 'However, the major capital investments are required.' The Town of Essex has four wastewater treatment facilities, two servicing Essex Centre, one for Colchester South, and one for Harrow. The Ontario Clean Water Agency (OCWA) operates the facilities. McGregor is served through the Town of Amherstburg. Each treatment facility has its own environmental compliance approval, issued by the Ministry of Environment, Conservation, and Parks. That allows the facility to be operated with environmental controls that protect human health and natural environment. The largest facility in the municipality is the Essex Pollution Control Plant, located on North Malden Road. It has been in service since 2005. This plant, Mackie said, is a Sequential Batch Reactor (SBR) plant, and also includes a temporary wet weather lagoon storage facility. The facility's current rated capacity is 4,590-cubic-meters per day. The average flow in 2024 was 1,983-cubic-meters. That is 43% of its rated capacity. It is estimated the facility will require $1.2M in capital expenses between 2025 and 2030, the majority of projects will replace equipment that are original to the building's construction. It has experienced two non-compliance events in the past two-years. Both were reported to the Ministry with corrective actions put in place. Both were later closed, Mackie noted. The North-East Lagoon is the second facility treating wastewater for Essex Centre. It is located on County Road 8 and has been in service since 1963. It has four cells that require Batch Allan dosing for phosphorus removal prior to discharge. The current rated capacity of the North-East Lagoon is 2,910-cublic-meters per day. In 2024, its average flow was 1,304-cublic-meters per day. That is 44% of its rated capacity. The facility is expected to require around $6.7M in capital expenses between 2025 and 2030. The majority of projects are due to the lagoon's cells requiring dredging, which will allow them to continue to function as designed, Mackie explained. There were no non-compliance or by-pass events with this facility in the past decade. The Harrow Lagoon facility is located on Roseborough Drive, and was established in 1974. It consists of five cells. There is one filtration building, consisting of two sand filters and phosphorous removal that discharges to the Richmond Drain. The Harrow facility's rated capacity is 2,106-cubic-meters per day. In 2024, its average flow was 1,034-cubic-meters per day. That is 49% of the rated capacity. Between 2025 and 2030, the Harrow Lagoon is anticipated to cost $1.7M in capital expenses, primarily for pump station upgrades to accommodate the future development at the former Harrow High School site, wet weather flows, and replacing equipment. There has been zero non-compliance issues or overflow events at the Harrow Lagoon in the past ten-years. The Colchester Lagoon is located on Cornwall Road, and has been in service since 1988. It has three sequentially operating cells with an aeration system. Its rated capacity is 1,861-cubic-meters per day. In 2024, the flow average was 953-cubic-meters per day. That is 51% of the rated capacity. Between 2025 and 2030, the Colchester Lagoon is estimated to require around $1.13M in capital expenses. A large majority of the expenses are contingent on the upgrade of the Colchester Lagoon into an SBR style plant, Mackie explained. Mackie noted that in April of 2024, Council committed $2.4M to complete a detailed design of the treatment plant, which is now around 60% complete. Essex Free Press files notes that last summer, Council applied for, and was not successful in earning, funding for the Colchester Water Pollution Control Plant under the Province's Housing-Enabling Water Systems Fund (HEWSF). Previously, it was noted the total cost estimate for the phase one upgrades for the Colchester Water Pollution Control Plant was estimated at $42.8M. If the Town wanted to look at completing the project around 2031 or later, the municipal contribution would be around $63M, as it would have to fund the entirety of the project, with around $20M in interest. Essex Council decided not to apply for the second-round of applications. In the past decade, there have been two non-compliance matters and one bypass events with the Colchester Lagoon. Mackie noted the bypass event took place in 2030, due to excessive rain. Around 7,207-cublic-meters were partially treated and bypassed. In April and June of 2024, total suspended cells were exceeded, due to cell three being out-of-service, due to dredging and maintenance. The Ministry was notified of all events, with corrective measures in place, Mackie added. All events were later closed. In Answering Councillor Rodney Hammond's question on whether or not the expenses projected for the Colchester Lagoon included flood mitigation, Mackie noted that is being incorporated in the design for the mechanical plant. Councillor Jason Matyi asked if there are any opportunities to increase efficiency by combining a sewage treatment plant between Harrow and Colchester. Mackie noted that would be a tricky and costly investment. When completing the Colchester Lagoon expansion Environmental Assessment, that option was screened. Director of Infrastructure Services, Kevin Girard, noted the distance between the two communities would not make combining services feasible. He added it is more difficult and costly to expand on a pump station network to pump sewage to another plant than to expand an existing sewage treatment plant.
