Soak-Away Test Report Gloucester
We have recently been commissioned to deliver a BRE 365 Soak-Away Test in Gloucester. The proposed development is residential.
From commissioning to issue of report the turnaround for this project was under 5 days.
The results were fair and we design the system in line with the planning authorities requirements, which was a 1:100 year rainfall event with a 40% allowance for climate change.
Southwest Environmental Limited carry out soak-away testing all over the UK. If you need a report for planning, or to aid with design then please get in touch and we can provide a fixed price.
P.s. The ground conditions on this job were sandy, with a touch of gravel. People often assume that if they see sand and gravel they will get a good result, but if there is an amount of clay in the sand and gravel mix, this can quickly reduce soakaway rates to low levels.

We have recently been commissioned to undertake a sunlight and daylight assessment in North London (N4).
The project is relatively small involving a roof extension.
We have been provided with plan for the proposal, as well as detailed elevations, and we will prepare a before and after comparison of sunlighting and daylighting conditions.
The BRE209 guide suggests that 20% reduction in lighting levels is acceptable, most projects fall within the 20% allowance.
If you are looking for an environmental consultant in London to undertake a Sunlight and Daylight Assessment then please call or email Southwest Environmental limited we would be very happy to assist and we can also provide design advice.

We have recently been commissioned to undertake a Permit Variation in Trowbridge, Wilshire.
The site has been running under an existing permit for a number of years, but an upgrade to some of their equipment will mean that an environmental permit variation.
On the face of things this would seem fairly easy, but in reality it is very tricky as the EA often ask for all kind of information, which might extend to activities outside of the variation.
For example if you were to vary the permit because you are installing a new boiler over 1 MW, they may also ask you to provide new emissions data on your abatement system for dust extract.
More often than not things can and do inflate past the requirements for what logically might be expected when varying an environmental permit.
If you would like to find out more please call for a no obligation chat.

Flood Risk Assessment - Bristol
Southwest Environmental Limited have recently been commissioned to prepare a flood risk assessment for a site in Bristol (Avonmouth). The site is subject to tidal flooding and, as if typical with the majority of the Avonmouth area, is low lying.
|Avonmouth - Docks|
Key factor explored in the flood risk assessment will be the anticipated flood depths from tidal, fluvial and pluvial (rain) flooding, and then design of mitigate measures.
In this instance the application is retrospective which will create further challenges. We will have to make sue of the current site lay out, existing outbuildings and other factor in order to present a positive proposal.
The report will include a Exception Test and Sequential Test.

Independent Review of Planning Documents - St Albans
We have recently been offered a small job by St Albans Council to look over a Planning Application, and provide steering on likely Environmental Impacts to the development.
The situation is quite unusual in that the a housing development was being assessed on the basis of proposed impacts from a large mineral working & landfill scheme, that had not yet commenced.
The mineral working (quarry) scheme in question had been approved by environmental permitting, but planning permission was still pending at the time of our review.
We reviewed the extensive Environmental Impact Assessment that had been submitted in support of the Quarry & Landfill Application.
We made review of the following Environmental Impact Assessment chapters:
- Noise Impact
- Dust Impact
- Bio Aerosol
Bio Aerosol and Dust risks typically fall away quite quickly at a distance of 250m from source, as the housing site was within 250 meters of the proposed quarry and landfill we recommended further assessment in these areas.
