Asset Management Services

An essential element of any good stormwater management program includes regular inspections, cleaning, and maintenance of installed pollution control devices to ensure that they continue to capture and retain pollutants to its designed specifications without premature by-pass.

Cleaning frequencies will vary and depend on the type of unit installed, weather patterns, pollutant loadings, and other activity within the catchment. Under normal operating conditions, we recommend two-monthly cleans for the RSF 100 and RSF 1000 and quarterly cleans for the RSF 4000 and Net Tech products. It is important that in the first year of operation the unit is monitored so that the appropriate cleaning regime can be determined. The RST 7000 Rainwater Storage and Re-use system is self-cleaning and therefore, largely maintenance-free with only periodic inspections needed.

Ecosol has a dedicated Asset Management Division to help you not only determine how often your unit should be cleaned but also with the cleaning and maintenance itself. We offer:

• The use of high-performance equipment operated by experienced staff;

• A long-standing record in safe work practices, supported by Quality Assured processes.

• In-depth knowledge and experience with all popular types and brands of GPTs (including CDS, Rocla, and Baramy);

• An complete understanding of pollution removal and disposal regulations and processes that ensures your unit is cleaned effectively and efficiently without risk of damage;
• Useful, easy-to-read reports, allowing you to track performance and pollution loading patterns - refer bottom of this page for a sample selection of our reports; and

• Tailored service contracts to suit individual requirements.

To ensure that all captured pollutants are removed, Ecosol units are best cleaned by vacuum (although the RSF 100 can be cleaned by manually removing the liner bag).

Cleaning by vacuum offers far greater benefits compared to all other methods. After many years of industry experience we believe that this is the safest, most efficient, and cost-effective method for the following reasons:

• All captured pollutants (and especially fine sediments) are removed from the unit;
• Pollutants are not manually handled and can be safely transported;
• Free oils and grease (hydrocarbons) are able to be efficiently removed and stored;
• No additional machinery other than the eductor truck is required;
• The internal filtration system is unlikely to be damaged during the cleaning process; and
• The cleaning costs are significantly less than for other methods.

Other GPT providers will urge you to buy their products because of the perceived benefits of using removable baskets. These benefits are illusory as you can see from the discussion topic in our FAQ.

The main disadvantage with a removable basket is that, prior to transfer to the disposal truck, it must be positioned over the unit to drain and this results in the return to the unit, and subsequent remobilisation, of harmful pollutants such as Total Phosphorous (TP), Total Nitrogen (TN), and Total Suspended Solids (TSS). In addition, sediment settled at the bottom and around the external sides of the screens remains in the capture silo and this may result in a misalignment problem when the cleaning operator tries to refit the basket into the unit.
