    Frequently Asked Questions.

    When is a wastewater system upgrade needed?

    Upgrades are needed when systems show signs of failure, are aged or no longer comply with regulations. 

    Why should I upgrade my existing wastewater system?

    Upgrading your system can improve treatment quality and system reliability and ensure compliance with current regulations. Modern systems are designed to be more environmentally friendly and can handle increased wastewater volumes more effectively. A new system can also make the property more attractive to potential buyers, as it is one less risk for any prospective purchaser. 

    How do I know if my system needs to be replaced?

    Signs that your system may need to be replaced include frequent backups, foul odours, slow drains or non-compliant effluent samples. Our experts can conduct a thorough assessment to determine the best course of action. 

    How do I choose between repairing or replacing?

    We assess the condition, regulatory gap, cost and performance to recommend whether remediation or full replacement is the best path.

    How long does the upgrade process take?

    Time depends on complexity, but planning, consenting and design often take weeks, while installation may range from a few days to weeks for complex systems. 

    Will my upgrade require a new consent?

    If the upgrade changes discharge quality, volume or location, a new or amended consent may be needed.

    Do you handle compliance after the upgrade?

    Yes, we validate system performance, provide documentation and support final compliance close-out with local authorities.

    Can GWE handle large-scale upgrades?

    Yes! GWE has the expertise and resources to handle both small residential upgrades and large-scale projects. We tailor our services to meet the specific needs of each client, ensuring optimal results.
