Frequently Asked Questions

What if I'm building a new property or converting into multiple units?
- If you're constructing a new property or converting an existing one into multiple units, it's essential to plan for the water main installation. A properly installed water main ensures a safe, efficient, and regulation-compliant water supply.
  Before starting construction, consult a professional to assess your project's water main requirements. This may involve upgrading an old system to handle increased demand or installing a new one that meets local building codes. Ignoring these requirements can lead to issues like low water pressure, contamination risks, disruption to water supply or legal complications.

Working with experienced water main supply specialists guarantees a reliable, safe water supply for your development.
