HSR Item 33.19-Development of tube well in accordance with IS : 2800 (part I) and IS: 11189, to establish maximum rate of usable water yield without sand content (beyond permissible limit), with required capacity air compressor, running the compressor for required time till well is fully developed, measuring yield of well by `V` notch method or any other approved method, measuring static level and draw down etc. by step draw down method, collecting water samples and getting tested in approved laboratory, i/c disinfection of tube well, all complete, including hire and labour charges of air compressor, tools and accessories etc., all as per requirement and direction of Engineer-in-charge. HSR Rate(Rs.) 1030.00 Through Rate

Supply, delivery, and installation of standalone water purification plant with solar pump set fitted with tube well, capable of removing contaminants such as iron, arsenic, etc. & bacteriological disinfection from the raw water as per the acceptable limits of IS: 10500:2012 including 3 months trail run and 21 (Twenty-one) months operation and maintenance after the trial run under PHED of Assam, which broadly comprises supply. Delivery, Installation, testing & Commissioning of standalone community water purification of BLDC Motor based solar pump set with tube well-having filtration rate not less than 2 m³/hr. the plant will be aided by photovoltaic submersible solar pumps within the bore well with a minimum yield of 10500 liters per day. (The plant is capable to work on solar energy (PV Panel), Lithium Ion batteries), the battery should be a Li-ion battery backup capable of giving a minimum of 2 hours of backup). The plant should treat the water from the minimum level of contamination of 5.0 ppm of iron and 2.0 ppm of Arsenic contamination in the raw water source available at the site and be able to purify the specified standards namely Arsenic0.01 mg/ltr. And Iron0.3 mg/ltr. (total concentration of manganese (as Mn) and Iron ( as Fe) shall not exceed 0.3 mg/ltr and bacteriological contamination as per BIS standard and conforming to MNRE norms & the norms prescribed in the Manual on Supply and treatment of CPHEEO. Filtration process technology is approved by CSIR-IMMT, Bhubaneswar.
