Marsh industries Cesspools for basic sewage storage has no outlet and relies on road transport for removal of raw sewage, for guidance Marsh industries domestic cesspools should have a capacity below the level of invert of at least 18,000 Litres for two users and should be increased by 6800 Litres for each additional person.

Marsh Industries Pump Chambers: Where foul water drainage from a domestic property is to be pumped to the mains the effluent receiving chamber should be sized to contain 24-hour inflow to allow for disruption in service, the minimum daily discharge being taken as 150 litres per person per day.

For other building types the capacity of the receiving chamber should be based on the calculated daily demand of the water intake for the building, or when only a proportion of the foul sewage is to be pumped then the capacity should be based pro-rata.

Marsh industries pump stations with single or twin pump configurations are available; please contact Allbits for further guidance if required.

Operating principle – Each Marsh industries pump chamber contains a number of float switches linked to a control panel that automatically controls flow and levels. In a single pump chamber there are three float switches, Float A: Actuates the pump cycle until level drops to low level.
Float B: Low level float stops the pump
Float C: High level alarm – positioned above the pump actuator float(min 100mm)

For a twin pump chamber an additional float switch Float D: usually positioned 150mm above the first actuator Float switch A:- which actuates the second pump in periods of high flow. After each cycle the pumps alternate to extend the pump life and are designed to run for a minimum of 60 seconds with no more than 15 starts per hour.

Separate layers of materials and keep them from sinking or disintegrating into each other. Drain areas where water pools while keeping soil in place.
