Design

Titan Agrément Certified Septic Tanks are designed to separate and settle the solids present in raw sewage leaving the resultant liquor to be absorbed in the soil.

A genuine 3 stage settlement tank minimises the risk of solids carry-over and ensures a long term maintenance free sub-system. The tank should be emptied once a year.

Model Selection

The size of development defines the capacity of the tank required.

Refer to Titan for capacities greater than 9000 litres

The grade of the tank required depends upon the invert level only.

Siting

The following should be considered when siting the tank and dispersal system:

• The site should preferably be a minimum of 15 metres from the nearest habitable dwelling

• The dispersal system should be a minimum of 10 metres from the nearest water course and at least 1 metre above the local water table

• Emptying vehicles should have access to within 35 metres of the tank

• A site which is subject to traffic loading should be avoided.

Products for the next generation

To establish the overall length of a drain run required a soil porosity test may be necessary. The following procedure should be adopted.

• Excavate a hole 300mm square by 250mm deep below the proposed invert level of the land drain

• Fill hole with water to a depth of 250mm and allow to drain away overnight

• Refill to a depth of 250mm and note the time taken to drain away completely

• Repeat this exercise two more times and calculate the average time

• By reference to the table the length of drain run required for various capacity tanks may be established.

A looped system of rigid perforated or butted land drains as shown should be laid in trenches lined with gravel. Coiled plastic drainage pipe is not recommended.

To ensure even distribution it is important for the land drains to have a uniform gradient of no more than 1 in 200

In circumstances where it is necessary to lift the effluent to a higher level for dispersal, we can provide a standard pump package for fitting after one of our septic tanks. This package comes complete with glass fibre pumpwell, fully submersible pump, automatic float control and all necessary internal fittings.

Installation

In all cases the tank should be seated on a firm concrete base. For a dry well drained site, backfill should be 10mm rounded pea single or similar. If the site is wet with poorly draining soil then the tank should be backfilled with concrete, filling with water at the same time to prevent flotation.

Effluent Dispersal

Where the water table and the nature of the soil allow satisfactory absorption, dispersal should be by means of a sub-surface irrigation system.

Treatment Plants

Where discharge is to a ditch or water course (subject to Environment Agency approval) further treatment is essential. Details of the comprehensive range of Titan Biotec sewage treatment plant are available on request.
