{{procontable | pro=

- Low cost alternative to metal or ferrocement tanks.<br>

- Good for areas where ground would otherwise be permeable.<br>

- They work well when privately owned and maintained.<br>

| con=

- Experience shows that subSub-surface tanks often cannot hold enough water for whole dry season. Making bigger berkeds is possible but more difficult and cost is high (unaffordable tank is not replicable on larger scale).<br>

- Flotation of the tank may occur in areas with a high groundwater table.<br>

- Heavy vehicles driving near to tank can cause damage.<br>
