LPU’s Innovative Water Reuse Strategy for Sustainability

Water reuse and recycle is the vital step towards water conservation. LPU has taken leading initiatives in this aspect. The sewage water has been segregated into black water and grey water and managed individually. The university employs an effective wastewater management strategy that distinguishes between greywater and black water to optimize resource use and environmental sustainability. Greywater, which includes wastewater from sinks, showers, and laundry, undergoes nominal treatment before being repurposed for landscape gardening and toilet flushing. In contrast, black water, which consists of wastewater from toilets, undergoes a rigorous treatment process to ensure it meets the effluent discharge standards required for safe release into the environment. This comprehensive treatment ensures that harmful contaminants are removed, safeguarding public health and protecting local ecosystems. Recognizing that conventional wastewater treatment can be energy-intensive and may not always effectively address all types of wastewater generated in an institutional setting, the university is continuously exploring innovative methods to enhance the efficiency and effectiveness of its treatment processes. By prioritizing both greywater reuse and advanced black water treatment, the university exemplifies a holistic approach to wastewater management that prioritizes sustainability, resource conservation, and environmental protection, setting a standard for responsible practices in higher education. Hence flexible wastewater treatment technologies ranging from conventional to advance has been installed and operated in order to treat all type of wastewater generated within the premises most effectively and energy efficient way. Gradually but steadily through these initiative, LPU is paving towards energy effective waste treatment and zero liquid discharge.

LPU’s Approach to Reusing Swimming Pool Water

Lovely Professional University’s approach to reusing swimming pool water. By maintaining stringent sanitation protocols and addressing challenges like calcium buildup, LPU ensures a safe and enjoyable swimming experience while significantly reducing water waste. This model can serve as an inspiration for other institutions and communities aiming to adopt sustainable water management practices.

The primary goal of these water management practices is to reduce impurities in the pool water to a safe level, allowing for its continuous reuse. The benefits of LPU’s approach include:

  • Water Conservation: By recycling pool water, LPU significantly conserves water, aligning with environmental sustainability goals.
  • Cost Savings: Reduced need for fresh water lowers operational costs associated with pool maintenance.
  • Enhanced Sustainability: Implementing such advanced water management systems demonstrates LPU’s commitment to sustainability and environmental management.

Sustainable Pool Water Management

Recycling Pool Water and reusing it in swimming pool water at Lovely Professional University: A Model for Water Conservation. Lovely Professional University (LPU) has recognized the critical importance of water conservation and has implemented innovative strategies to minimize water waste, particularly in the maintenance of its swimming pools. The university has introduced restrictions and practices aimed at recycling pool water rather than draining and refilling it, thereby setting a precedent for sustainable water management.

A significant measure adopted by LPU is the use of Reverse Osmosis (RO) systems for pool water treatment. This advanced filtration technology enables the university to maintain clean and safe pool water without the need for frequent draining. Here’s how the RO system contributes to water conservation:
  • High-Pressure Filtration: The RO system uses high pressure to force pool water through a fine semipermeable membrane. This membrane effectively retains salts, cyanuric acid, calcium, and other impurities.
  • Water Reuse: Clean water is returned to the pool, ensuring that the water remains safe and pleasant for swimmers. The separated contaminants and dirty water are then pumped out and managed appropriately.
  • Reduction of Water Waste: By recycling the pool water through the RO system, LPU significantly reduces the volume of water that would otherwise be wasted through draining and refilling.
Sanitation and Maintenance
To ensure that recycled pool water remains safe and hygienic, LPU employs a comprehensive sanitation protocol:
  • Filtration: Regular filtering removes particulate matter and debris from the water.
  • Chlorination: Chlorine is used to disinfect the water, killing bacteria, microbes, and other potential contaminants.
  • pH Level Maintenance: Maintaining the correct pH level is crucial to prevent skin irritation and to ensure the effectiveness of chlorine. LPU monitors and adjusts the pH levels meticulously.
25,000 litre large water storage tanks build to store treated water that reducing reliance on municipal water supplies

Strategic Management of Sustainable Water Storage at the University
The university has made significant strides in sustainable water storage management through its initiatives to capture, store, and utilize treated water across campus. One of the most impactful efforts is the installation of three large water storage tanks, each with a capacity of 25,000 liters, located at the Sports Fields. These tanks are designed to collect and store treated water, which is used to irrigate the fields, reducing reliance on municipal water supplies and conserving valuable freshwater resources. This system ensures that the sports fields remain well-maintained year-round, even during periods of low rainfall or water restrictions, while minimizing the environmental footprint of campus operations.

The water storage management initiative not only supports the university's commitment to sustainability but also demonstrates how institutions can effectively manage natural resources to meet their water needs. By capturing treated water and putting it to productive use, this forward-thinking approach aligns with the university's broader goals of environmental stewardship, resource conservation, and the creation of a resilient, self-sustaining campus.
