Amount

Designing ,Manufacturing, Providing and Installing, commissioning and Testing of Horizontal Filtration Module is Precast Modular Step well of M25 grade, designed to capture sediments primarily from surface runoff water as per approved design. This Octagonal shape structure has a circumscribing diameter of minimum 918mm and a height of 1700 mm. A part of the top module of is usually kept above the ground however same can be flushed with ground.100 / 150 mm are the available height options in case part of it has to be kept above the ground level. Top module accommodates indigenously designed 2-nos Array Filters 315mm dia to capture sediment effectively within the Horizontal Filtration Module. This easily removable array filters can be cleaned within or outside the module using pressurized water. Total filtration area of this filter is approximately 3000 cm2. Filtration capacity is 8m3 to 10m3 per hour. This module is installed prior to the sand filtration Module.The inlet and outlet is of 110 mm diameter UPVC pipes connected with sand filtration Module and leaf chamber , openable top Lid and bottom slab.

Providing and Installing, commissioning and Testing of Sand Filtration Module M-25 grade cement concrete system with nominal steel of 8 mm dia @100mm c/c for rainwater harvesting with SS 304 screen and natural filters. It consists of single module with internal volume of approximately 0.8 cubic meters that is to be fixed below ground level. The module is of an octagonal shape with a diameter of minimum 1000 mm below ground level. Total height of the system is 1700 mm. Filtration capacity and testing up to 8m3 to 10m3 per hour from modular systems only. The inlet and outlet of the system is 90mm diameter UPVC pipes. Module holds a filter media in the form of sand bed around a continuous slot fine aperture stainless screen (420 mm diameter and 240 or 300 mm length). Screen is fixed to the bottom slab and is fully covered by 0.10 cubic meter filtration sand with 40mm graded gravels. Screen creates entry points for the filtered water.
