Sewage safely stored in a holding tank
A voidable holding tank can be used to collect sewage in infiltration systems with double sewerage. The holding tank is required to be hermetically sealed and have a very strong structure, as the tank must be able to withstand fluctuating and demanding soil conditions.
At only 1.5 metres tall, the Uponor holding tank has a strong structure and is extremely easy to install. If necessary, two 5.3-cubic-metre tanks can be combined using a connection package to provide a 10-cubic-metre holding tank. In coastal and groundwater areas, the municipality may require holding tanks to be used if holiday homes have water-based toilets. Holding tanks are not required if chemical toilets are used.
