Horizontal cistern

→‎Suitable Conditions

- 7000L tank with pump costs US$ 70 in Bolivia <br>

- Tank occupies little space – is less noticeable <br>

- Easy to filter roofwater before it entering enters the tank <br>- Temperature underground is more constant – cracks are likely <br>

- Does not require ground to be firm, like the vertical cistern. <br>

| valign="top" | - More complicated to build than a vertical cistern <br>

- If the cistern is an open underground tank, contamination (livestock, rainwater runoff carrying pesticides) is more probable, therefore a lid is recommended.<br>

- Cracks are likely and harder to detect.
