5361- Kilmainhamwood Compost Facility Extension- EIS
2.3.5 Wastewater Treatment Plant
Wastewater to be generated by the proposed facility administration building will be collected and
processed in an existing proprietary wastewater treatment plant located on site. Details of this plant are
provided in Appendix 2.3. Any sludge removed from this plant will be collected by Thorntons Tankering
Services and sent to an approved facility for treatment.
The existing treatment plant on site is designed to process a total flow of 720 litres per day. The
proposed facility administration building is designed to serve both office staff and staff directly working
at the composting facility. There will be a total of six staff members employed at the facility.
As per the E.P.A. Guidelines for Treatment Systems for Small Communities, Business, Leisure Centres
and Hotels – Table 3, the estimated loading rate per person for Industrial Office without canteen is 30
litres per day.
Hence the existing waste water treatment plant and associated percolation area is more than adequate
to serve the proposed facility administration building.
2.3.6 Existing On Site Borehole
The existing borehole well (BH3) is located adjacent to the existing water storage tank on elevated
ground. An onsite water treatment plant at the point of entry to the facility administration building to treat
the well supply to drinking water standard will be developed. It is proposed to provide a package plant
in the tea station, within the proposed facility administration building, providing chlorination and filtration.
All of the parameters on the water analysis from the existing borehole (BH3) are within the limits set for
drinking water under the EU drinking water directive. Chlorination will be introduced to ensure
disinfection of the water and filtration to maintain the distribution network clean.
2.3.7 Surface Water Drainage
For inspection purposes only.
Consent of copyright owner required for any other use.
Two networks of surface water pipes serve the existing facility, the first collecting roof water and the
second collecting run off from the yard.
All surface water run off from the roofs of the existing facility buildings is collected and reused where
possible within the composting process. Surplus surface water run off is piped to a drainage ditch
located along the eastern boundary of the site and flows in a south-eastern direction (See Figure 8.1)
prior to eventually discharging into the Dee River.
It is proposed that the additional surface water generated by the proposed facility extensions and facility
administration building will be reused where possible within the composting process with any surplus
surface water run off diverted to the drainage ditch located along the eastern boundary of the site.
