Water and sewer applications and Unitywater certification

Capitan Engineering Group is a Unitywater Accredited Major Certifier. That means we can certify water and sewer works for developments in Unitywater's service area, which covers Moreton Bay, the Sunshine Coast and Noosa.

We handle the whole process: the network design, the application, certification and supervision of construction through to handover. We also prepare water and sewer applications for Urban Utilities in Brisbane, Ipswich and Logan.

What we provide

  • Water and sewer network design to the SEQ Water Supply and Sewerage Design and Construction Code
  • Water and sewer connection and network applications
  • Certification of design as a Unitywater Accredited Major Certifier
  • Construction supervision and inspections
  • As-constructed certification and handover

Why use an accredited certifier

Using an accredited certifier lets the design and construction certification be carried out by the project's own engineer, under Unitywater's accreditation scheme. Because we designed the works, we already know the details when it comes to certifying and supervising them, which keeps the process moving.

Projects we certify

We certify water and sewer works for residential subdivisions, multi-residential developments, mixed-use and commercial projects. If you are not sure whether your project needs a water and sewer application, we can check the requirements for your site.

Frequently asked questions

What is a Unitywater Accredited Major Certifier?

It is an engineer accredited by Unitywater to certify the design and construction of water and sewer works that will become Unitywater assets. Capitan Engineering Group holds this accreditation.

Which areas does Unitywater cover?

Unitywater supplies water and sewer services in the Moreton Bay, Sunshine Coast and Noosa council areas. Brisbane, Ipswich and Logan are served by Urban Utilities, where we also prepare applications.

Do you supervise construction of the water and sewer works?

Can you take on a project another engineer designed?

Often, yes. Contact us with the project details and we will confirm what is needed to take over certification.
