Urine from seated users is diverted away from the compost pile. This is beneficial as it reduces the amount of “soak” material required and makes it possible to reduce vault size. Vault drainage is not required and the risk of ammonia smells is virtually eliminated. A ceramic wall mounted urinal is usually provided for men. Urine is a very useful fertiliser since it contains an almost perfect balance of plant nutrients. Subject to any statutory requirements we usually advise on disposal of urine to ground where some of the useful nutrients can be made use of by plants.
