==Technical specification== ====Operation==Construction, operations and maintenance==Basic water quality testing is recommended during the first year, with further testing when water quality is in doubt. EgE.g. the 'HACH' pillo test, costing about US$ 1 per test. Treatment to manage microbiological quality is also recommended.
====Maintenance====
* Removal of debris and overhanging vegetation from gutters and the roof (preventing stagnation of water in the gutters) is required. Physical inspection and repairing cracks with cement is also needed.
====Manufacturing====
Material costs for EMAS tanks consist of sand and four 50 kg bags of cement for each tank.
