Re: EMPLOYMENT LAND TO THE NORTH OF , MAPLE CROSS LODGE, MAPLE CROSS, RICKMANSWORTH, HERTFORDSHIRE , WD3 9SN

Waste Comments The proposed development is located within 15 metres of a strategic sewer. Thames Water requests the following condition to be added to any planning permission. "No piling shall take place until a PILING METHOD STATEMENT (detailing the depth and type of piling to be undertaken and the methodology by which such piling will be carried out, including measures to prevent and minimise the potential for damage to subsurface sewerage infrastructure, and the programme for the works) has been submitted to and approved in writing by the local planning authority in consultation with Thames Water. Any piling must be undertaken in accordance with the terms of the approved piling method statement." Reason: The proposed works will be in close proximity to underground sewerage utility infrastructure. Piling has the potential to significantly impact / cause failure of local underground sewerage utility infrastructure. Please read our guide 'working near our assets' to ensure your workings will be in line with the necessary processes you need to follow if you're considering working above or near our pipes or other structures.https://developers.thameswater.co.uk/Developing‐a‐large‐site/Planning‐your‐ development/Working‐near‐or‐diverting‐our‐pipes.

Hi Claire,

Unfortunately we have submitted a response prematurely and prior to reviewing all elements of the application and are keen to submit revised comments.

The elements under further consideration are the proximity to the nature reserve and the Sewage Treatment Works.

I’m currently pulling comments together from relevant parts of the business and will send them through asap.

If you’d like to discuss this further could I ask you to give me a call please?

Many thanks

Waste Water Comments

With regard to SURFACE WATER drainage, Thames Water would advise that if the developer follows the sequential approach to the disposal of surface water we would have no objection. Where the developer proposes to discharge to a public sewer, prior approval from Thames Water Developer Services will be required. Should you require further information please refer to our website. https://developers.thameswater.co.uk/Developing-a-large-site/Apply- and-pay-for-services/Wastewater-services.

The application indicates that all surface water will be discharged to Springwell Lake to the south east of the site. Affinity Water abstract water from this area so their comments will need to be taken in to consideration. If technically feasible there may be environmental benefits in discharging surface waters to the watercourse north east of the development. These do however, drain to the Maple Lodge Nature Reserve and therefore the water quality would need to be of an appropriate standard.

Thames Water would advise that with regard to FOUL WATER sewerage network infrastructure capacity, we would not have any objection to the above planning application, based on the information provided.

There are public sewers crossing or close to your development. If you're planning significant work near our sewers, it's important that you minimize the risk of damage. You’ll need to check that your development doesn’t limit repair or maintenance activities, or inhibit the services we provide in any other way. The applicant is advised to read our guide working near or diverting our pipes. https://developers.thameswater.co.uk/Developing-a-large-site/Planning-your- development/Working-near-or-diverting-our-pipes.

The proposed development is located within 15 metres of a strategic sewer. Thames Water requests the following condition to be added to any planning permission. No piling shall take place until a PILING METHOD STATEMENT (detailing the depth and type of piling to be undertaken and the methodology by which such piling will be carried out, including measures to prevent and minimise the potential for damage to subsurface sewerage infrastructure, and the programme for the works) has been submitted to and approved in writing by the local planning authority in consultation with Thames Water. Any piling must be undertaken in accordance with the terms of the approved piling method statement. Reason: The proposed works will be in close proximity to underground sewerage utility infrastructure. Piling has the potential to significantly impact / cause failure of local underground sewerage utility infrastructure.

Odour Comments The proposed development is located near to Thames Waters' Maple Lodge Sewage Treatment Works. Future occupiers of the development should be made aware that they could periodically experience adverse amenity impacts from odour and other operational activities.

Water Comments With regard to water supply, this comes within the area covered by the Affinity Water Company. For your information the address to write to is - Affinity Water Company The Hub, Tamblin Way, Hatfield, Herts, AL10 9EZ - Tel - 0845 782 3333.

Biodiversity Comments

With regard to wildlife and biodiversity this development should take into account the adjacent land uses of Maple Lodge Nature Reserve https://www.maplelodgenaturereserve.org/ which is fed by the stream at this development’s northern boundary. Maple Lodge Nature Reserve is a site of Importance to Nature Conservation (SINC) and is located 50m south-east of the proposed development. It is a nesting site for Tawney Owl (Amber listed status and protected under Countryside and Wildlife Act 1981), as well as hosting a range of notable aquatic insects and amphibians.

Wayleaves & Easements

There are easements and wayleaves running through the site. These are Thames Water Assets. The company will seek assurances that they will not be affected by the proposed development. On the Map attached a blue outlined box shows the assets, yellow dashed lines show the easements and wayleaves and the proposed development area is identified by a red outlined box.
