[[Image:PlasticLining.jpg|thumb|right|400px|Catholic Relief Service (CRS) is implementing a project to rehabilitate impluvia (underground water catchment basin) with local PVC liner. It will also put in place a management committee, which will be trained after rehabilitation as well.]]

[http://www.akvo.org/rsr/project/16/ Low cost rehabilitation of impluvia with PVC liner in Madagascar] by CRS and Practica, has very nice photographs of the process of installing these type of tanks.

Design of the tank shape and size based on the soil type, which dictates the side slopes. For stable and unstable soils the side slopes are recommended to be 1:1 and 1:2 respectively.
