As the population increases threat to the ecological system becomes inevitable. Billions of lives have become part of this gamble that mankind plays. Water pollution is one of the most adverse environmental pollutions. Water is the most essential factor that is required by the living form to sustain in the universe.

More than 70% of the earth is covered with water, out of which just 30% is present in freshwater form. Majority of the freshwater is frozen in the form of glaciers and on the lands of antarctica. Very small quantities of the remaining are marked as fit for drinking and irrigation purposes. Irreversible damage has been done to most of the freshwater bodies. Constant use of these water bodies as dumping areas for the industries and drains has led to depletion of the quality of water. Quality of water from these water bodies when tested shows very high chemical concentrations, low dissolved oxygen, high algal blooms, and sludge concentration. Even after realizing the value of water, we keep on contaminating it with all kinds of organic and inorganic wastes.

Golf courses are seen to face problems due poor quality of irrigation which has led to the degradation of the turf.

Turf being very sensitive is susceptible to damage even with the slightest contamination of water. Several factors like pH, Total Dissolved Solids (TDS), Dissolved Oxygen (DO), nutrient concentrations (Na, Mg, Cl, SO4, P, Al, NO3, etc.), are to be optimized before considering the quality of water to be fit for irrigation. Slight changes in these conditions result in poor quality of water, making it unfit for irrigation purposes. High sulfur and phosphorus content in the water bodies leads to algal blooms which in turn results in low dissolved oxygen. This unbalances the ecology of aquatic life. Water with low DO when used for irrigation of turf results in poor development of the roots. Whereas the high nutrient contents may lead to nutrient toxicity in plants and degradation of the soil. Therefore, the improvement of water quality for the irrigation of the turf is needed for an hour for most of the golf courses.

Remediation of waste water supply at DGC

Lack of availability of good water quality for irrigation is the major issue faced by the Delhi Golf Course. The current supply of water is provided to them is the treated waste water from the Okhla STP. The source of water thus is unreliable. The quality of water supply is not appropriate for irrigation purposes. The waste water from Okhla STP is stored in the Bio-STP Pond with water holding capacity of 1.8 ML. However, the water holding capacity of the filtration unit is 1.1 ML per 14hrs.

Significant increase in water quality was observed during the course of the treatments. The pond was treated by the waste water management products Aquaritin waste water and Bacterial Culture. TDS was seen to be decreased by 80.2% and the organic matter was reduced by 80-90%. The algal bloom was brought into control by the reduction of Phosphorous and sulfur contents. As the quality of water was increased, a very significant change in the turf quality was also observed.

However, the availability of water as per the requirements of the daily demands was still a problem. At peak summer the water requirement for irrigation is 3MLD, whereas the usable irrigation water at the moment is 1.5MLD. The problem is thus solved by the ongoing project of construction of the new Bio-STP which will meet the daily water requirements of 3MLD. along with the provision of good quality of water supply for irrigation of the turf.
