Comments<br />
Wastewater management and water supply services are currently inadequate in Coomba Park. This is evident in the high faecal coliform counts of up to 19,000 CFU.100ml -1<br />
recorded at drain sites in Coomba Park in 2000 (<strong>Wallis</strong> Catchment Community Waterwatch program, analysed by Forster Environmental Laboratory).<br />
<strong>The</strong> Small communities wastewater risk assessment (MidCoastWater, 2000) for the Manning and <strong>Great</strong> <strong>Lake</strong>s region ranked Coomba Park as the second highest priority for the<br />
provision of appropriate effluent services in the <strong>Great</strong>er Taree and <strong>Great</strong> <strong>Lake</strong>s Shires. However, Coomba Park is low on the State Government ranking for funding to provide<br />
these services. It is recommended that the WLEMIC consider coordinating lobbying efforts to increase the priority of Coomba Park for State Government funding for wastewater<br />
services.<br />
MidCoastWater is began conducting detailed stormwater monitoring at Coomba Park during dry, wet and peak period wet weather events in 2004. <strong>The</strong> results of this testing will<br />
influence the timeframe within which appropriate effluent services must be provided. <strong>The</strong> costs associated with this action may be significant (eg $8,910,000 for the option of<br />
providing sewerage services), therefore it is recommended that MidCoastWater begin planning for appropriate wastewater services as soon as this data is available.<br />
In recognition of the long flushing times and significant seagrass habitat in the south of <strong>Wallis</strong> <strong>Lake</strong>, any options for wastewater management in Coomba Park involving the<br />
disposal of treated effluent into the <strong>Lake</strong> are discouraged.<br />
