Creation of Blue Corridor Water body with State of Art Technology aimed at Reuse of Treated Effluent in Integration with existing 1.40 MLD STP at Upper Dharamshala Dist Kangra HP

Amount

Evolving planning, hydraulic design, construction, installation, testing, commissioning, of blue corridor (waterbody), minimum area 600 sq.m. in integration with reuse of treated effluent of the existing sewage treatment plant of 1.40 MLD at upper Dharamshala, for Dharamshala Smart City, H.P. including construction of main approach road & culverts, internal roads & pathways, peripheral walls, cover arrangements for existing sludge drying beds, digital sign board and other site development works within the battery limits of STP area. The created Waterbody should be capable for treatment of treated effluent from existing STP for the reuse (other than potable and bathing) as per the parameters described in CPHEEO manual with latest amendments. The scope of the work includes Construction of blue corridor having minimum area of 600 sq.m. with proper compacted base and side slope provided with geo-liner and bentonite arrangements. The side slops should have RCC M-30 bends for stone pitching, MS railing meter 1.50 meter heigh of approved design, scattering flood lights (minimum 20 Nos.), MSERW zink coated pipe 600 meter for conveyance of treated effluent for reuse, ozonator for hybrid disinfection, hume pipe culvert (7.5 meter wide), main approach road (3 meter wide), internal roads, peripheral walkways, parking area development, boundary wall (200 meter length) with MS railing landscaping and gardening STP premises, polycarbonate sheet covering arrangements for existing bio-solid units (plan area 220 sq.m.). The cost of supporting structure for stability of proposed structures wherever required should be borne by the firm/contractor. The waterbody should be designed to meet minimum dissolved oxygen level (4 ppm) for survival of aquatic life. The design methodology for waterbody should be supported with design kinetics based on CPHEEO manual / latest authentic references duly vetted from IIT/NIT/PEC and all the process design constants and kinetic equation used should be supported with authentic references. Refer chapter vi (b) to (c) for basic data, scope of work, Technical specification & Terms & conditions.
