Foul Drainage doesnt have to be a stinky business
We undertake the private and adoptable foul drainage design across a number of sectors, with our designs being site specific and will be fully compliant with sewage sector guidance and Water Authority requirements.
Our expertise is helping you unlock the development potential of your site, no matter what the size – from house extensions to 5000+ units, Aegaea works alongside you every step of the way.
Scope of Foul Drainage
We undertake the private and adoptable foul drainage design across a number of sectors, with our designs being site specific and will be fully compliant with sewage sector guidance and Water Authority requirements. When considering your specific drainage requirements, we can advise on the best foul effluent disposal option available to you.
We can assist where a site requires a sewer requisition, diversion and build-over, and if reinforcement works are required to upgrade or increase the capacity of the existing network, and liaise with the Water Authorities as necessary.
We liaise with the relevant stakeholders, including Water Authorities, Environment Agency (EA), Natural Resources Wales (NRW), Lead Local Flood Authorities, etc. to gain the necessary technical approvals and agreements, i.e. Section 104, 106 and 185, permits and consents.

Foul Drainage Design
We are experienced in the design of non-mains drainage, including discharge to surface water (i.e. river, stream, canal) and to the ground (i.e. drainage field). Consideration will be given to whether the site is in a sewered area or if there are any environmental designations, protected sites, etc. that may affect the strategy.
Percolation testing (to BS 6297:2007+A1:2008) will need to be undertaken to confirm whether a discharge to ground, i.e. drainage field, is feasible and provide a percolation value to inform the design, and we will coordinate the testing with a client-appointed contractor. We are able to advise whether an EA permit is required subject to a review of the general binding rules and additional rules.
Aegaea has a wide range of experience including:
- Design of Section 104 foul and surface water sewers for adoption by the local water authority.
- Design of Section 185 sewer diversions and build over agreements including adopted sewers.
- Environment Agency permits and consents.
- Hydraulic modelling of existing and proposed drainage networks.
- Foul pumping stations and rising mains.
- Foul treatment plants for single and multiple dwellings including commercial and industrial settings.
- Coordination of percolation tests and drainage field design
