Planning
Please ensure all necessary permissions have been sought and granted and
ensure that due consideration/ appropriate action has been given/ taken
regarding the following:
• Planning Permission, Building Regulations, and other
regulating or interested parties
• Environment Agency, SEPA or Natural Resources Wales requirements
• The size of the plant is in line with the British Water Flows
and Loads codes of practise
Ground conditions
Ground conditions and water table level should be assessed before installation.
Please ensure local ground conditions are suitable for the installation by assessing
the following factors at your installation site:
• Risk of high water table or flooding
• Underground rivers, running sand and chemicals in the soil
• Proximity of designated protection areas such as:
- wells, bore holes, and springs used as sources of potable water
- existing non-mains sewage systems and soakaways
- water courses, ponds and lakes
- other services, pipes, cables and ducts
• Sites which are close to trees (particularly willows) or shrubs
considering root proof membrane
High water tables
Installing in an excavation that allows water to enter the plant, has a high ground
water table or is susceptible to flood conditions will cause problems during
installation and may affect the plant during de-sludging.
For installations in a high water table or clay soiled areas, backfill with a dry-lean
concrete mix to approximately 150mm below the lid.
