WATER - The other side (south) of Lime
Park there is a sewage treatment plant that serves Chapel Row and
Church Road residents but has too small a capacity to be considered for
the extra 70 houses in Herstmonceux.
This picture shows a JCB excavating near the treatment plant. Note
the new build seen in the top right hand corner of this photograph.
- CONDITION 26 SEWERAGE FOUL WATER DRAINAGE
26. No development shall commence on the development approved by this permission until a
scheme for the provision and implementation of foul drainage works has been submitted
to and approved in writing by the Local Planning
Authority. The scheme shall include a
survey of the off-site foul sewerage system which will connect the development to the
Windmill Hill Wastewater Treatment Works to assess the condition and capacity of the
existing sewerage system. The submitted details shall identify any necessary upgrading
in the form of either additional off-site sewers or improvements to existing sewers to
provide the necessary capacity for the development hereby approved. Any works
required to upgrade the infrastructure sufficiently to provide capacity for the new
development shall be undertaken prior to acceptance of any of the development's foul
sewage. The foul drainage works shall be carried out in accordance with the approved
plans before the associated buildings to which they relate are occupied. DF02(M)
REASON: To protect water quality and to secure a satisfactory standard of development,
having regard to SPO12, SPO13 and WCS14 to the Wealden Core Strategy Local Plan
2013, Saved Policy CS2 of the adopted Wealden Local Plan 1998, coupled with the
requirements of paragraph 109 of the National Planning Policy Framework 2012. With
regard to Regulation 35 of the Development Management Procedure Order 2015, it is
essential to avoid increasing the risk of off-site flooding, that the condition adopts the precommencement
OUTLINE APPLICATION HERSTMONCEUX WD/2015/0090/MAO - CONDITIONS
The officer dealing with the above application for Wealden District
Council is Graham Kean.
His Memorandum dated 12 May 2015 records these observation for Mrs Claire
1.2. In accordance with that condition:
· A survey has been undertaken by the Sewerage Undertaker (Southern Water) which has resulted in a Section 98 Sewer Requisition in order to provide a suitable offsite sewer for the disposal of foul water from the development. Southern Water’s reference is SWS-S98-000519 v2, dated 10/11/2017 (copy of letter attached in Appendix 1) and has been
accepted and payment made in order to progress; and · A full drainage design has been undertaken for the onsite foul drainage
The site is located off Gardner Street, to the south-east of Herstmonceux, and is centered on national grid reference E563798, N112404.
Existing public foul sewers have been located within Gardner Street to the north. To the northwest, within Gardner Street, is a foul network which runs east-west before running north to a pumping station (Gardner Street WPS). The pump main from the existing pumping station runs south to Gardner Street and then west-east along Gardner Street, discharging into a gravity main approximately 300m east of the site. This gravity sewer runs north-east to the Windmill Hill Waste Water Works.
3.6. A second foul network runs from a point to the south of the site discharging into the Lime Park Herstmonceux Waste Water Works, approximately 300m to the south.
The existing site is greenfield and no existing connections to foul infrastructure have been identified.
4.2. Investigations were undertaken as to whether the existing Lime Park Waste Water Works could be connected to under gravity and it was confirmed that the works themselves were not adequately sized to receive flows from a further 70 residential dwellings and would require
reconstruction and consenting.
4.3. Any foul drainage solution would need to be received by existing or new infrastructure to the north of the site and would require a pumped solution, to overcome the topography.
4.4. Under Section 98 of the Water Industry Act, Southern Water were instructed to progress a solution of the offsite infrastructure upgrades required to support the development. Appendix 1 contains the offer letter received from Southern Water under this process.
4.5. The technical solution offered by Southern Water is to provide new and improved infrastructure in Chapel Row and Gardner Street as part of the Section 98 Requisition.
A gravity system of foul drainage has been proposed, based upon the approved illustrative layout, which collects the waste from the 70 units and drains to the south-west corner of the site, adjacent to Chapel Row.
5.3. A private pumping station has been proposed adjacent to Chapel Row which will collect the foul flows and pump them into the proposed foul rising main provided by Southern Water under the Section 98 application.
Pumping station design (Private)
5.6.1. The design of the pumping station has been based upon the following design standards and documents:
· BS EN 752; and
· Building Regulations 2010 part H.
5.6.2. Storage capacity within the pump station has been provided in accordance with the
requirements setout by Building Regulations, Clause 2.39. The receiving chamber has been
sized to contain 24 hour inflow to allow for disruption of service. The following design criteria
has been applied using the mix of residential units and flow volumes (in accordance with British
Water Flows and Loads 4) below:
5.6.4. Due to the overall depth of the pump chamber installation (circa 6.5m) it is likely to be adversely impacted by groundwater, which has been profiled at a depth of 42.000m AOD in the area. Additional measures both in the final design and construction of the chamber will be required to counter buoyancy and groundwater infiltration of the excavation.

many to be downright dangerous without the appropriate visibility
splay. The A271 is a narrow country road that is
already overloaded - with many traffic jams in the village high street
causing motorists serious delays on occasion. The increase in traffic from
a dense residential development at this location is nothing short of

is likely to change with more markers in the Herstmonceux area on the east
side of the village as the inadequate visibility splay gets to work
catching out unwary motorists and residents who have relied on Graham Kean
to do the right thing in ensuring their long term safety - rather than
giving the developers virtually free license to develop a site in spite of
the obvious limitations.
