A PROCESS TO RESOLVE DRINKING WATER SCARCITY

Abstract A process to resolve drinking water scarcity by dividing a conventional well into two cells namely the outer core and the inner core. The inner core is a watertight reservoir. The outer core is the inner side of the normal well filled with pebbles / coarse sand to facilitate easy flow of water. The inner core and the outer core are connected with non-return valves (NRV) at different levels to maintain the water level and to facilitate flow of water from outer to inner core. The non-return valves (NRV) prevent the draining out of water from the inner core even when the level in the outer core goes down.

This invention relates to a process used in to solve drinking water scarcity.
Background of the invention:
From time immemorial people depend on wells for drinking water. Conventional well overflows during rain and most often dry up during summer due to percolation. A study of erosion in wells during the last rainy season is the root cause for this invention.
Even today majority of the population in the marl area of our country where public water supply is inadequate depends mainly on wells for drinking water. The very aim of this invention is to find a foolproof solution for the problem of drying up of the well and erosion of wells.
One of the main reason for drying up of well is percolation. If percolation can be prevented water scarcity can also be controlled. By implementing this method, we can overcome the drying up of wells.

Detailed description of the invention
Firstly the we 1 is divided into two cells, namely the outer core and inner core. The inner core is a watertight concrete reservoir. The outer core is the inner side of The normal well filled with pebbles/coarse sand to facilitate easy flow of water in the outer core. The inner core and the outer core are connected with non-retimed valves (N.R. V.) at different levels to maintain the water and also to facilitate flow from outer to inner core, when the level in the o -tar core comes up, water flows to inner core whereas the NRV

prevents the draining out of water from the inner core, even when the level in the outer core goes down.
If any chocking occurs at the mouth of NRV, it can be cleared by water/air flushing system provided.
In the event of excess consumption and evaporation, if the water level in both inner and outer core goes down unprecedently can draw the water stored in the chest through the sump provided at the botchy.
The water from the summer rain which goes unexploited 6an be tapped by diverting the water from roof surface/run off water to the outer core thievery enriching the yield.
The introduction of inner core and outer core system also prevents the caving and erosion of wells.
The invention can be more clearly described with reference to Fig. 1 to 3 of the accompanying drawings.
Inner & Outer Core (1 & 2 of Fig. 3)
The inner core is a water tight concrete reservoir made up of a series of concrete rings with flange or in one unit. This is the main storage tank. The outer core is the space between the inner face of the normal well and the concrete face of inner core filled with pebbles / coarse sand.;
Non-return valve (NRV) - (3 of Fig. 3)
The outer and inner cores are connected with NRV. This maintains the water level and also facilitates the flow from outer core to inner core.
The screen (4 of Fig. 3) {
The screen provided at the mouth of the Nerve’s to prevent accumulation and entry of solid particle that may cause choking of valves.

Flushing system (5 of Fig. 3)
A pipe line connected to the entry of each NR V'S to clear the chocking by air/water flushing.
The Chest (6 of Fig. 3)
This is the bottom part of the well which acts as a second reservoir to collect the spring water which can be used when acute shortage comes due to excess consumption and evaporation.
The sump (7 of Fig. 3)
A small pit fitted with NRV'S provided on the bottom concrete plate to receive the water from the chest through NRV'S.
RCC bottom plate (8 of Fig. 3)
This is the lowest part of the inner core. This is a concrete divider for inner core and the chest to prevent water leaking through bottom.
RCC Shoe (9 of Fig. 3)
The inner core and bottom plate rest on the RCC shoe. The shoe has weep holes to receive spring water into the chest.
Dry Rubble Masonic (10 of Fig 3)
This is the lowest part of the well which is the foundation and leveling course, prevent erosion and caving of well. This will also, act as another source for receiving spring water into the chest.
Ground Water Tank (11 of Fig 3)
A small masonry tank at the ground level to collect direct the rain water getting in the form of surface / roof/ run-off water.

Plastic netted roof (12 of Fig. 3)
This prevents the entry of unwanted foreign materials into the well, which causes chocking and contaminating water.
Cement Concrete Platform (13 of Fig. 3)
This is provided for the protection of surroundings of the well.
Pebble-Coarse sand Filling (14 of Fig. 3)
This is provided to facilitate easy flow of water in the outer core.
Watertight Joint (15 of Fig. 3)
This is a reinforced cement concrete ring set in watertight to prevent leakage in the joints.





Claim
I claim a process to resolve drinking water scarcity by preventing the percolation in the wells and to facilitate easy flow of ground water in to a well by dividing a conventional well into two cells namely the outer core and the inner core and connect the outer core and the inner core with no return valves (NRV) as described in the specification.
