One sheet of lamina is 900 Lempiras, and is 12 feet long. Each lamina in the plate settler is 3 feet long, so four lamina can be made from one sheet. The tank is 4.3 meters long, and there are lamina every 5 cm, so 86 lamina are needed, or 29 sheets per tank.

The tank dimensions are 14 feet long by 42 inches wide, giving an area of 49 square feet.&nbsp;

The cost of couplings and pipe werewas taken off Mcmastercarr.com, and may not reflect actual prices in Honduras.

The couplings are 4 cm long, therefore lamina spacing is 4 cm rather than 5 cm. This means that a total of 36 twelve foot sheets of lamina are needed.
