Do they have toilets in Vanuatu?

Yes we have toilets we use a 

• Septic system. A septic system is an underground wastewater treatment system used in areas where there is no access to a centralized sewage system. It consists of a septic tank, which collects and treats the wastewater from the household, and a drainfield or leachfield, where the treated wastewater is dispersed into the soil. The septic tank allows the solids in the wastewater to settle and be broken down by bacteria, while the liquid portion is released into the drainfield for further treatment by soil bacteria.
  
  
• A bio cycle toilet is a type of composting toilet that uses aerobic bacteria to break down human waste into compost. The composting process helps to reduce the volume of waste and eliminate the need for traditional sewage systems. Bio cycle toilets are often used in remote or off-grid locations where traditional plumbing and sewage systems are not practical or feasible.
