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.

3 · Design rainfall (intensity–duration)
Jeddah Stormwater Design Manual 2019 — Built-In IDF. Valid 15–720 min only; the tool runs a 1-minute Rational-IDF screening scan and does not extrapolate beyond 12 hours. Return periods: 2/5/10/25/50/100/200/500-yr (no 20-yr).
Enter the approved duration–intensity pairs (mm/hr). Use only durations published in your source. The tool compares the entered cases — it does not interpolate between them.
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
Passive Irrigation module
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.
