CWE-ES-04 Compassion, Welfare & Environment Environment & Sustainability CORE Excellence v2.9.7

Water Conservation Measures Implemented

Evaluates implemented water conservation systems, a key indicator of fulfilling the *khilāfah* (trusteeship) by avoiding *isrāf* (waste). In Islamic jurisprudence, preserving vital natural resources aligns deeply with *maqāṣid al-sharīʿah* (objectives of Islamic law), specifically *ḥifẓ al-nafs* (preservation of life) and *ḥifẓ al-māl* (preservation of wealth). Furthermore, prophetic traditions strictly prohibit excessive water usage, even at a flowing river. Ultimately, this commitment to stewardship lowers operational costs, mitigates environmental impact, and strengthens trust with stakeholders who value resource preservation.

Compliance 2
  • Procure/install WRAS‑approved fittings (retain certificates) and use WaterSafe‑accredited installers.
    Process Critical
  • Update Legionella risk assessment and flushing regimes when flow rates are reduced or auto-shutoffs installed.
    Safety Critical
Basic 1
  • Implementation of specific measures (e.g., installation of low-flow fixtures, regular leak detection).
    Process Important
Good 4
  • Documented water conservation policy or plan.
    Documentation Important
  • Evidence of regular awareness programs or training for staff and facility users on water conservation practices, referencing Islamic principles of stewardship.
    Training Important
  • A documented preventive maintenance program for plumbing systems that includes proactive leak detection and a rapid repair protocol.
    Process Important
  • Staff and user awareness campaigns (promoting complete but non-wasteful wudu)
    Stakeholder Engagement Medium
Better 10
  • A system for tracking water consumption against a baseline.
    Monitoring Important
  • Establishment of annual, quantifiable water reduction targets with documented progress reviews.
    Performance Important
  • A formal water audit conducted at least biennially to identify inefficiencies and opportunities for improvement.
    Monitoring Important
  • Define a 12‑month baseline normalised using occupancy/footfall proxy and irrigation/weather data.
    Planning Critical
  • Sub‑meter significant water uses and implement AMR; complete monthly trend analysis site-wide, weekly review for high‑risk zones, and monthly night‑line/leakage tests.
    Monitoring Important
  • Leak repair SLA and MTTR tracked (≤24h urgent; ≤72h non‑urgent).
    Process Important
  • Regular water audits
    Continuous Improvement High
  • Use of water-wise landscaping on premises.
    Sustainability Medium
  • Specify low‑flow fixtures: taps 3.8–5.7 L/min; showers 6–8 L/min; dual‑flush WCs 4.5/3 L
    Operations High
  • Urinal controls or waterless urinals
    Operations High
Best 2
  • Installation of rainwater harvesting or greywater recycling systems
    Sustainability High
  • Sub‑metering with AMR and leakage analytics (UKWIR good practice)
    Monitoring High
