Technical explainers, design guidance, and field notes from the NGS engineering team — written for consultants, contractors, and developers working on Saudi infrastructure.
The complete guide — why it matters in an arid climate, infiltration vs attenuation, how soakaways are designed, the governing standards, and the systems NGS supplies.
Read the guide →The codes and authorities that govern SuDS, soakaway and geocellular design in the Kingdom — SBC, MOMAH, Balady, CIRIA and BRE — summarised with a link to each official source.
Read the guide →Who approves stormwater works in the Kingdom, what Balady is for, and the typical path from hydrological study to municipal permit.
Read the guide →Plain-English definitions — soakaway, attenuation, infiltration, percolation, void ratio, sabkha, IDF curve, SuDS and more.
Open glossary →How the ground is tested before a soakaway is designed — the BRE 365 method, the infiltration rate, and how it sizes the system.
Read the guide →Stormwater in arid climates arrives in sudden, intense events. Conventional pipe networks are sized for the wrong problem. Here's the engineering rationale for SuDS in the Kingdom.
Coming soonLessons from delivering Saudi Arabia's largest SuDS project — value engineering from ponds to AquaCell, site logistics, and training the installation crew.
Coming soonWhat actually happens to a containment liner over five decades of Saudi heat, UV, and salinity — and how we specify materials accordingly.
Coming soonHow to approach soakaway design for a Saudi site — infiltration testing, design rainfall, void ratio, and safety factors. A primer for early-stage design.
Coming soonGeo-cellular tanks versus conventional pipe-and-pond drainage. A side-by-side comparison of footprint, cost, installation speed, and lifecycle performance.
Coming soonThe carbon mathematics behind replacing mineral-based construction with geosynthetics — and why it adds up to a significant reduction.
Coming soonOur engineering team is writing the full Knowledge Hub now — in-depth explainers on SuDS design, geosynthetic selection, and waterproofing for Saudi conditions. New articles publish here regularly. Have a topic you want covered? Tell us.
