External works in Morocco: sewers, water mains, roads and subdivision infrastructure

External works in Morocco combine land-use law and product standards. For a subdivision, Law 25-90 requires the developer to build the infrastructure and obtain its provisional acceptance before the plots can be occupied; Law 34-21 amending it had been adopted but its official text was not yet online at the date of the catalogue. Water use, discharges and rainwater fall under Law 36-15, and the local distributor sets connection conditions. Sewer pipes in PVC-U and structured-wall plastics, PE and PVC water mains, road bitumens and street lighting columns and luminaires carry mandatory NM references. Topographic surveys must be done by a registered surveyor under Law 30-93.

Scope

This page covers everything outside the building footprint: foul and storm drainage to the public sewer or to an on-site treatment system, water, electricity and telecom mains, driveways, car parks and paving, kerbs and gutters, street lighting, retaining features and planting, and the infrastructure of a subdivision or housing group.

Work starts with the topographic survey and the distributor's requirements, continues after the main structural works, and ends with as-built records and the final connections. Garden swimming pools have their own package; the building's internal drains stop at the first external inspection chamber.

Inspection milestones

  1. Topographic survey and title concordance Legal obligation
    Topographic survey by a registered surveyor, consistent with the land title, before any design of levels and networks.
  2. Subdivision permit granted Legal obligation
    Subdivision authorisation granted before any infrastructure works on a subdivision.
  3. External works, plot drainage and pool Specification (CPS) requirement
    Distributor requirements in hand, trench depth, bedding and warning tape, sewer falls and invert levels, chambers watertight, backfill compacted, as-built recorded before covering.
  4. Provisional acceptance of subdivision infrastructure Legal obligation
    Provisional acceptance of the subdivision infrastructure by the municipality and the distributors.
  5. Final utility connections Legal obligation
    Final connection of water, sewer and electricity by the distributors.

Common non-conformities and follow-up

FindingAction
Sewer laid with a reverse or insufficient fall.Excavation and re-laying of the section before backfilling, followed by a new inspection or test.
Trench backfilled before the as-built survey.Opening at key points to record positions and depths, at the contractor's expense.
Pipes delivered without marking or in a class lower than specified.Rejection of the delivery and supply of marked pipes of the specified class.
Road surface settling over a trench after the first rains.Removal of the surface, re-compaction of the trench backfill in layers and reinstatement.

Frequently asked questions

Who must carry out the topographic survey?

A registered surveyor, under Law 30-93. The survey is the base for levels, networks and the land title check.

When can plots in a subdivision be occupied?

Under Law 25-90, after the provisional acceptance of the infrastructure built by the developer. Check also the effect of Law 34-21 once its text is published.

Which pipes are mandatory for sewers?

PVC-U sewer pipes and structured-wall plastic pipes have mandatory NM references, as do the PE and PVC pipes used for water mains.

What if there is no public sewer?

An on-site treatment system is needed. No specific national regulation was found; distributors' rules and the homologated standard NM EN 12566-1 guide practice.

Why record networks before backfilling?

Buried networks are invisible afterwards. A georeferenced as-built record avoids damage during later works and is often required by the distributor.
