Description

Concrete rings are disposed vertically in the ground to create a pit or a well if water table is near the surface.

The concrete ring with no holes is used in the upper part of the well to avoid surface infiltration or for waste pits requiring encapsulation (ashes, sharps) in this case the bottom of the pit should be sealed with concrete.

The concrete ring with holes is used in the bottom part of wells to allow water infiltration or in the bottom part of organic pits to allow organic fluids to infiltrate.

The concrete ring does not suits construction of soak away pit as such. it should be combined with infiltration system.

Materials costs only: 5 to 10 USD

Dimensions: 

Size: 1,14m external diameter, 1m internal diameter, 0,6m high. 300 to 350 Kg per ring

Sizing variable : the Ring can be made higher, thicker or larger but this implies higher weight and manutention difficulties. size as proposed is optimal for transport and remote field handling

Scalability: Add the number of ring needed to reach target depth of pit capacity. Combine with or without holes as needed.

Construction requirements

  • Type of construction: permanent
  • Can be locally manufactured. (requires specific molds to precast and mason competences)
  • Check that the pit will not affect the groundwater, or be affected by it.
  • Basic skills required for construction/installation: eventually well digger, mason
  • Quantities break down (composition):

Operation requirements

  • Operation skills - complexity: basic for manutention of rings
  • For manutention: requires handling system (crane and/or manutention staff with PPE)
  • For transport: the vehicle must be able to handle the weight (350Kg/ring)

Safety requirements

  • For worker safety during construction, they must wear dedicated PPE for concrete ring handling (working closed shoes, working gloves)
  • The concrete ring pit shall always be covered with concrete slab with proper resistance corresponding to its use (vehicle path…)
  • Any application of concrete ring use implies underground work. Impact on water table must be evaluated and mitigation measures shall be taken
