Supply, Delivery and dosing of ISI grade 10% Poly Aluminum Chloride (PAC) strength of AL2O3 for Treatment of Raw (River) Water at water treatment plants in Head Water works. The scope of work Includes: 1) Logistics & Inventory: Supplying and safely unloading the chemical from tankers directly into the primary storage tanks, alongside managing internal transfers to day tanks at the filtration plants. 2) Dosing & Application: Precise mathematical calculation and continuous addition of PAC into the flash mixers to prevent under- or over-dosing. 3) Guaranteed Water Quality Parameters: a) Turbidity: Maintained strictly below 5 NTU, completely independent of the incoming raw river water turbidity levels. b) pH Levels: Maintained at a minimum of 7.2, allowing only a tight variation of + 0.1 relative to the incoming river water pH. 4) Quality Assurance & Reporting: Rigorous testing of turbidity and pH levels across clarifier overflows, filter beds, and final discharge points. We will submit detailed bi-hourly analysis reports capturing raw, process, and supply water metrics. 5) Risk Mitigation: Maintenance of mandatory backup reserve stocks of alternative water treatment chemicals on-site to handle any unforeseen transit delays or extreme emergency conditions. complete as directed by departmental authorities
