ANGUS LOCAL PLAN REVIEW FINALISED PLAN - Angus Council

Policy ER21 : Public Drainage SystemsWithin towns and villages served by public sewers alldevelopment proposals requiring drainage must be connected tothe public drainage system. Private drainage solutions will notbe permitted within areas served by public sewers, even wherethey are subject to constraint.Policy ER22 : Private Drainage SystemsDevelopment proposals requiring the private provision of wastewater treatment plant, biodiscs, septic tanks or similararrangements will only be acceptable where:-(a) the site is located outwith the public sewerage network;(b) the proposed development is in accord with the developmentstrategy and other relevant policies of the Local Plan;(c) there is no detrimental effect to a potable water supply, orsupply for animals or an environmentally sensitive watercourse or loch; and(d) the requirements of SEPA and/or The Building Standards(Scotland) Regulations 1990, as amended, are met in relationto installation, e.g. proximity to other buildings.Surface Water Management3.48 In the Angus towns and villages much of the existing drainagenetwork is a combined system which deals with both foul water andsurface water run-off from roads, roofs and other impermeablesurfaces. This significantly reduces the capacity of the foul drainagenetwork during storm water conditions. Scottish Water does notaccept surface water run-off from new greenfield development intothe foul drainage network and separate arrangements are requiredfor surface water disposal. Depending on local circumstances sucharrangements will also be required for brownfield redevelopmentsites.3.49 Developers are required to make appropriate provision for thecollection, treatment, decontamination and disposal of all surfacewater arising from development sites to the standards andrequirements of SEPA, Angus Council Planning & Transport andRoads Departments and Scottish Water as appropriate. Isolatingpollutants at source and providing the necessary treatment canreduce the potential for pollution. The use of permeable surfaces andother water attenuation measures designed to slow surface waterrun-off from the development site can reduce the risk of flooding inwater catchment areas. Detailed guidance on the effectivemanagement of surface water run-off through the use of SustainableUrban Drainage Systems (SUDS) is provided by PAN61: Planningand Sustainable Urban Drainage Systems (2001) and the SustainableUrban Drainage Systems - Design Manual for Scotland and NorthernIreland (2002).PAN 61: Planning andSustainable Urban DrainageSystems (2001)Sustainable Urban DrainageSystems (SUDS) aim to deal inan integrated way with surfacewater, based on the followingprinciples:• managing surface water runoffon-site as near to sourceas possible;• slowing down run-off;• treating it naturally; and• releasing good qualitysurface water towatercourses orgroundwater.Sustainable Urban DrainageSystems - Design Manual forScotland and Northern Ireland(2002):prepared by the SustainableUrban Drainage ScottishWorking Party the Manualprovides a definitive source ofadvice for SUDS design,planning and implementation inScotland.Angus Local Plan Review75Finalised Plan
