development is an extension to Enfield WwTP to increase the treatment capacity. The development will consist of:
a) 11 No. Reed Beds measuring approximately 20m (long) by 15m (wide) by 2.0m (high)
b) 2 No. reinforced concrete Final Settlement Tanks (approximately 1,300 m3) with associated access/viewing platform;
c) 1 No. WAS Holding Tank (approximately 90m3);
d) 2 No. 60m long Transfer pipelines beneath the bed of the River Blackwater between the new and existing treatment infrastructure
e) 1 No. Sludge Import facilities;
f) Construction of various pump sumps and the installation of duty/standby pumps;
g) 1 No. approximately 2m by 1.5m Box Culvert
h) New site surface water drainage pipework, sustainable drainage attenuation and manholes,
i) New internal roads including splays and turning areas;
j) Installation of a new 2.4 m high wire mesh boundary fence with lockable access gates;
k) New outfall to the River Blackwater for treated effluent and attenuated surface water runoff;
l) Landscaping and reinstatement including tree and hedge planting;
m) Localised scour protection and bank repair works to a part of the riverbank;
n) New kerbs and flood defence measures on the existing WwTP site;
o) Decommissioning of existing clarifiers, belt press and Picket Fence Thickener and all ancillary works.
Access is via an existing access off the R402.
