Usually made from medium-density polyethylene, these tanks are durable, frostproof and maintenance-free.

Most of the time, the only access to any of the system components is via the manhole, although there might be many of them, like float switches, pump, inlets and outlets with equipments, filters, etc. Sometimes water distribution unit can also be found here. Hence it’s extremely important the manhole must be accessible for service purposes all the time.
