Below are some Questions and Answers recently received from Scottish Water in Relation to the proposed new waste treatment plant in Kippford.  

Scottish Water have asked us to note that : "we are still in the very early stages of design so we do not have all of the answers just yet."

Question

Recognising that test bores may show the proposed site to be unsuitable, what other potential sites have been identified? Please rank these in terms of suitability.

Answer

In regards to the other options considered, firstly, we looked at other options including transferring flows to Dalbeattie or Rockcliffe and extending the existing site. These were ruled out early on for a number of reasons with transfers being unsustainable and costly to build, whilst the existing site was found to not have enough land for new infrastructure.

In identifying the early options for the location of a new Wastewater Treatment Works in Kippford, we were looking at sites with a number of criteria in mind. These included the potential route of the rising main from the existing works; the ease of site access for the construction and on ongoing operation of the site; how much traffic management might be needed in construction; the number of pre-existing utilities that may need to be crossed; the visual impact of the works; customer service and operational considerations and; the location of a new outfall.

We came up with three early options which appeared suitable for consideration. Two of these sites were located near to the option which is being explored. One was to the north east of the entrance to Merse Way on the road into the village and another was to the west side of Merse Way. Both of these sites were deemed less suitable as they would be visible. Further to this, the one by the road would have issues in terms of outfall construction and the one to the west of Merse Way would be more difficult to access.

The site which we currently believe to be the best option is to the north of Merse Way within a natural depression and would be well screened by the natural landscape and trees. The benefit of this site is that it should be well hidden from view and is close to the estuary making an outfall simpler to construct. The site also has the benefit of having an existing access track. 

We believe that a site somewhere around this area would be best for a new works because of the amount of space potentially available and the topography of the land there.

However, we are still early on in the process and we are keen to listen and work with the community over the coming months. I am keen to organise a site visit towards the end of January for those in the community who are interested where we could do a walk over and show exactly the area we are looking at. Does this sound like something that you would be interested in and would a week day be acceptable for this?

Questions

Assuming there will be pumps and other equipment operating at the site, what decibel noise levels can be anticipated?

I understand that sewage storage will be underground. If it is in sealed tanks, I assume there will need to be venting off of the gases that build up. How does this work?

Answer (jointly)

Due to the early stages of developing this project, the types of pumps and associated noise levels are not yet known and are subject to a noise impact assessment.  These decisions will be made once further investigations have taken place.

In regards to the parts of the works which would be associated with odours and the venting of these, we need to carry out detailed odour assessments prior to construction. These would highlight the areas where extra mitigation might be needed.

I would like to reassure you that on both of these issues there are a lot of technologies in existence to effectively mitigate these risks.

Question

Once operational, how many site visits per month can be anticipated. Will this be the only traffic using the access road round Merse Way?

Answer

There will be approximately four de-sludging visits required per year where a sludge tanker would need to access the site. There will also be a requirement for our operations team to regularly attend the site in normal vans for maintenance purposes.
