A professional SuDS design workspace for consultants and contractors on Saudi infrastructure — design soakaway/infiltration, attenuation/storage and passive-irrigation systems, get a recommended NGS AquaCell product, and export a stamped-ready engineering report. Built on international practice: BRE Digest 365, DWA-A 138 and the CIRIA C753 / C737 SuDS manuals.
Enter the minimum site data for a preliminary design. Results update live; export a full engineering report when ready.
Project & engineer
1 · Catchment & runoff
2 · Design rainfall (intensity–duration)
Enter rainfall intensity (mm/hr) for each storm duration at the selected return period. The tool finds the critical storm. Values are an example — replace with your site/SBC data.
IDF equation: i = a / (t + b)c, with i in mm/hr and t in minutes. The tool evaluates the standard durations (15–1440 min).
3 · Soil & infiltration
4 · Tank geometry & levels
5 · Product & loading
Geo-Cellular = high-capacity 500 mm modular tank (load classes 30/45/60T) for large volumes. EXO = premium high-strength shallow cells (85–250 mm) for high-load/landscaped sites (also passive irrigation).
In development
Attenuation / Storage module
A full consultant-grade attenuation design tool — controlled-discharge storage sizing to CIRIA C753, flow-control / orifice design, flotation check, compliance matrix, risk profile and downloadable engineering report — is being built on the same standard as our live Soakaway module.
Need an attenuation or storage design now? The NGS Engineering team can prepare a sealed design for your project.
A landscape water-balance tool for AquaCell EXO sub-irrigation — ET₀ / Kc crop demand, soil water-holding capacity, capillary-rise reservoir sizing, autonomy and % demand met, annual water savings and potential LEED contribution — is in development on the same engineering-report standard as our live Soakaway module.
