Abstract
A funnel structure for filtering and discharging storm sewage into an aquifer from a bottom of a manhole. The funnel is adapted to receive unitized filters. These filters can be selected from known materials to most effectively remove known types of contaminants from the storm sewage. The structure is designed to be employed both as a new installation, say within a park or a residential subdivision, to reduce leads on the storm sewage system and as an adaptation to existing manholes within a storm sewage collection system, thus augmenting the capacity of that system.
Claims21
A structure for filtering and discharging surface water and storm sewage into a storm sewage receptor, comprising:
- a surge basin for receiving said surface water;
- a filter funnel mounted to the surge basin, the funnel including a top end having an intake opening for receiving said surface water from said surge basin, a central portion having sidewalls and a bottom end having a discharge opening leading directly to the storm sewage receptor;
- a filter means including a porous sack of filtration material positioned within the central portion of the funnel for removing contaminants from the surface water flowing therethrough, said sack of filtration material being adapted flatten when supported from below to prevent the by-pass surface water therearound;
- and
- the filter funnel including filter support means positioned below a portion of the filter means for supporting the filter means in the filter funnel.
A structure as claimed in claim 2 wherein said storm sewage receptor is a well hole leading to an aquifer.
A structure for filtering and discharging storm water into an aquifer characterized by a surge basin for receiving said storm water;
- a non-porous funnel tube mounted to said surge basin and disposed in a well hole leading to the aquifer so that all storm water entering the aquifer passes through the funnel tube, the funnel tube having an intake opening for receiving the storm water from the surge basin, and a discharge opening for discharging said storm water into the aquifer;
- removable filter means located in the funnel tube, the filter means including granular filtration material adapted to flatten out therein, so that no storm water entering the intake opening by-passes the filter means to the discharge opening.
