Anti-flood protection systems THE NEED FOR ANTI-FLOOD PROTECTION SYSTEMS

Cause and effect A combination of global climate change together with increasing population densities have placed new demands on drainage infrastructure. For some properties, there is potential for flooding caused by backflow from foul or combined drain systems.

Global climate change

The resulting effects are not only confined to financial costs but also potentially impact health and the short term habitability of the property.

Anti-flood protection systems THE NEED FOR ANTI-FLOOD PROTECTION SYSTEMS

Defining the need Overview

Defining risk

Various factors in combination contribute to the risk of sewage flood in a building. The problem is addressed in UK Building Regulations, which, together with other Standards describe measures to help prevent such an occurrence.

Differing local conditions require consultation with the sewerage undertaker in order to determine the extent and frequency of surcharge. Table 1 lists contributing factors.

Normal operation

Backflow situation

Where the risk is considered low, an anti-flooding device should be fitted to sanitary appliances within the basement or other affected areas. If considered high risk, a wastewater lifting plant maybe necessary.

Table 1 Risk driver

Comment

Potential of surcharge from a combined sewer system

Although not current design practice, a legacy of combined foul and rainwater sewers exist. Changing rainfall intensity and duration coupled with increased run-off from hard landscaped areas all affect surcharge potential.

Potential surcharge from foul sewer systems

Foul sewers are not designed to surcharge. However network additions or blockages may compromise or overload the system during peak use.

Position of ground floor level relative to flood or backflow level

Possible scenarios are illustrated graphically overleaf.

Anti-flood protection systems THE NEED FOR ANTI-FLOOD PROTECTION SYSTEMS

Backflow level This diagram shows a conventional property that is not at risk of sewer surcharge backflows as the backflow level, or street level, is below the ground level of the building.

Surcharged drain and sewer

Backflow/flood level

This diagram shows a property with a basement that is lying below the backflow level and is therefore at risk of sewage backflow flooding during flood conditions.

Backflow/flood level

Basement

In this case, due to the site falls, the backflow level is above the ground level of the property and therefore at risk of backflow flooding.

Automatic and emergency

Type 2: Anti-flooding device in horizontal pipes having two automatic closure devices and an emergency closure device, where the emergency closure device may be combined with one of the automatic closure devices. Automatic

Outflow

Backflow

Emergency

Automatic (automated)

Type 3: Anti-flooding device in horizontal pipes having an automatic closure device actuated by external energy (electrical, pneumatic or other) and an emergency closure independent of the automatic closure device. Outflow

Anti-flood protection systems INSTALLATION OVERVIEW

Connection of other appliances not through anti-flood system

Basement toilet connected to sewer via anti-flood system

Surcharged sewer and connecting pipes

Anti-flood system Type 3

The anti-flood system should be installed as indicated in the diagram above. Here only the basement toilet is connected to the system. 1st and 2nd level floor toilets are connected to a discharge stack that connects to the sewer after the anti-flood system.

All anti-flood systems require periodic maintenance. It is therefore necessary to install the product in an accessible area. ACO Building Drainage offer purpose made installation chambers for this purpose.


Anti-flood protection systems INSTALLATION

ACO Junior M Where the product is to be installed in an existing room engineering advice may be necessary to accomodate in-situ damp proof membranes.



Lay the product on a bedding mortar taking care to set the grating level approximately 3mm maximum below finished floor level.



Connect outlet drainage and surround product to within 50mm of grating with concrete.



Lay screed or alternative finished floor material



Fill gully with water to obtain foul air trap.

Screed Concrete surround min 100mm strength class C20/25

ACO ARA/SERA Our instructions assume the use of ACO SERA/ARA installation chamber. Engineering advice should be taken on other proposed methods of installation.



Install the lower section of the unit on bedding mortar ensuring alignment and connection to incoming and outlet drainage pipework. Note that the red emergency closure handle represents the outlet “end� of the product.



Surround in concrete up to membrane flange.



If using membrane, apply suitable adhesive to polypropylene membrane flange following manufacturers instruction. (For further information on damp proof membranes contact Visqueen Building Products 01685 840672).



Ensure all service connections are laid through conduit removing blank plug as necessary.



Install the upper section with cover. Adjust to set the cover to finished floor level. Lay further support concrete around the unit to screed level.



Lay screed.



Ensure emergency closure valve is open by turning fully clockwise.
