• Soakaway Calculations and Design Expert soakaway design using the BRE 365 formula, providing accurate calculations for sizing soakaway storage volumes based on infiltration rates and impermeable areas.
• SuDS Reports Sustainable Urban Drainage Systems reports for planning applications that assess and recommend strategies for managing surface water runoff in urban areas using eco-friendly approaches that mimic natural drainage regimes.
• Attenuation Pond Design Design of attenuation ponds for storing and slowly releasing surface water to manage stormwater runoff and reduce flood risk on development sites.
• Attenuation Swales Design of shallow, vegetated channels that capture, filter and slow down stormwater runoff, mimicking natural processes while removing pollutants and sediment.
• Section 38 Application Formal request to local authorities for adoption of new highways under the Highways Act 1980, ensuring roads meet necessary standards for public maintenance.
• Section 104 Applications Applications for adoption of drainage networks, ensuring drainage systems meet technical standards for adoption by authorities.
