1987). The climate is generally mild, with relatively high humidity and fairly high, evenly distributed annual rainfall . Soils are volcanic and varied, and include deep ash soils, well-drained alluvial soils along rivers, and sandy soils near the coast. Slopes within the broader landscape around the potentially affected sites range from gently undulating to strongly rolling. The Waiwhakaiho River is a narrow, single channel river, typically 10-m to 30-m wide, set within a

Whilst the average daily discharge limit was exceeded on two consecutive days under high rainfall conditions, the Company identified and eliminated stormwater discharges to the system in a timely fashion. Additional operational changes were made to minimise daily discharge volumes. The wastewater treatment system at the Retreat did not adversely affect the water quality of the local freshwater and coastal environments. The results of this sampling suggested that the Retreat was not influencing

Background Taranaki has over 500 named rivers and streams, many of which contain spots or places valued for swimming. However, water quality in the region, as in other parts of New Zealand, varies dramatically with the weather. Taranaki’s high rainfall means that even our cleanest waterways may exceed recognised

There were eight conditions associated with this consent which set out how the consent shall be operated and managed. Condition 1 was a review provision. page 12 Condition 2 set out the terms of use of the consent during heavy rainfall only. Condition 3 set limits on the components of the discharge. Conditions 4 and 5 placed limits on the concentration of

Microfloral populations have not indicated poor performance of the treatment system to date and generally indicate an improvement in conditions in the tertiary cell since the last WWTP upgrade. Screening of the outlet from the secondary oxidation pond was well maintained. The inlet system functioned as designed during the monitoring
