We are at the beginning of an important journey to balance construction with nature and look forward to working with housing developers and councils and local communities to achieve Nutrient Neutrality.
The Consortium has well over 30 years of experience working with Septic Tank systems throughout England, and especially in the Home Counties and East Anglia. Working with Norfolk County Council, Natural England, the Environment Agency and by using modern, efficient equipment our teams have installed thousands of septic tanks. This has effectively led to hundreds of kilos of Phosphorus and thousands of kilos of Nitrogen nutrients being removed from Norfolk’s rivers, streams and coastal waters.
As a result, Norfolk’s waters are becoming less contaminated with waterborne pathogens (bacteria, viruses and human waste).
The reduction of excessive nutrients is helping ease eutrophication and algae build ups that in turn improves water oxygenisation.
Household liquid waste including detergents, cleaning products and chemicals do not reach rivers with our advanced septic tank solution.
By working closely with Councils and Residential Housing Developers, NRC can significantly reduce direct discharge of treated wastewater effluent into watercourses and in turn reduce pollution.
