National Trust
Trusted by the National Trust for Rural Property Foul Drainage Solutions
Since 2009, Mantair has been proud to include the National Trust on our client portfolio. We have conducted detailed surveys and offered our expert services to maintain and improve the foul drainage systems of over 180 of their properties across East Anglia.
Our extensive experience ranges from charming country cottages to bustling visitor centers, ensuring that each location meets the highest standards of environmental compliance and functionality.


The National Trust, established in 1895, is dedicated to preserving places of historic beauty across England, Wales, and Northern Ireland. Their stewardship includes 166 grand houses, 19 castles, 47 industrial monuments, 49 churches, chapels, and 35 pubs and inns, each requiring tailored solutions to protect their unique character and surroundings.
In response to evolving legislation on foul drainage systems, the National Trust has entrusted Mantair to conduct thorough inspections, recommend necessary upgrades, and handle replacements of aging septic tank systems. Our comprehensive service package includes obtaining all required Environment Agency and Building Regulations approvals, as well as Planning permissions.
