The Complete Drainage Compliance Checklist for Property Owners and Developers
Navigating the legal and technical requirements of drainage installations can be complex, especially for property owners and developers undertaking new builds or refurbishments. Whether you’re working on a residential site in Ringwood, planning a rural conversion, or managing a multi-property development, full compliance with the General Binding Rules is essential.
A successful project hinges not only on correct installation, but also on accurate ground assessments such as a percolation test, properly conducted pre-purchase surveys, and an understanding of when Environmental Agency Discharge Permits are required. This article provides a comprehensive checklist covering every stage of drainage compliance, helping to ensure legal certainty and environmental safety.
Why Compliance Matters in Drainage Installations
Failing to follow drainage legislation can result in significant legal and financial consequences. Non-compliance can lead to environmental damage, fines, and in some cases, a requirement to completely overhaul an existing system. Adhering to the General Binding Rules—which govern discharges from small sewage systems—is fundamental. These rules, enforced by the Environment Agency, are especially relevant to properties in sensitive regions such as Ringwood, where groundwater protection zones and proximity to watercourses may impose stricter conditions.
Every stage of planning and construction must be underpinned by expert assessment, design precision, and awareness of statutory obligations.

Initial Planning and Site Evaluation
- After frequent or severe weather events that stress your system.
- During property renovations or extensions.
- If you’ve recently purchased an older property in Salisbury with outdated drainage.
- When local authorities introduce new environmental or drainage regulations.
Soil Testing and Percolation Assessment
A percolation test is legally required when planning to discharge to ground via a drainage field. This test determines whether the soil can safely and effectively treat and absorb effluent.
- Comprehensive services, from addressing blocked drains to installing sewage treatment plants.
- Advanced technology, including CCTV surveys and trenchless techniques like drain re-lining.
- Environmentally friendly solutions, such as efficient soakaways and sustainable materials.
- Expertise in both modern systems and traditional methods, like pitched fibre repairs.
Without a successful percolation test, discharge to ground is not permitted under the General Binding Rules, and alternatives must be considered.
Pre-Construction and System Design Considerations
In addition to environmental and soil assessments, proper design and preparation are critical to ensuring drainage installations are safe, efficient, and legally compliant.
Pre-Installation Requirements
- Conduct full pre-purchase surveys for existing properties or sites being acquired. These inspections identify system condition, legal status, and risk areas.
- Assess the need for upgrades or replacement of existing septic tanks or treatment plants.
- Ensure minimum distance requirements are met (e.g., 10m from watercourses, 50m from potable water supplies).
- Obtain planning permission or building control approval where applicable.
Installation Standards and Legal Documentation
Not all drainage systems fall under the General Binding Rules. When the rules cannot be satisfied, an Environmental Agency Discharge Permit becomes mandatory.
Discharge Permit requirements include:
- Detailed design submissions and technical specifications.
- A full risk assessment of the discharge’s environmental impact.
- Ongoing system monitoring and periodic renewal of the permit.
This is especially relevant in Ringwood, where high water tables and protected habitats may trigger additional regulatory oversight.
Post-Installation: Maintenance, Monitoring & Reporting
Once a system is installed, owners and developers must maintain it to ensure continued compliance.
Ongoing Responsibilities
- Arrange for regular emptying and servicing of septic tanks and treatment plants.
- Keep maintenance records for a minimum of five years.
- Monitor for signs of failure such as odour, ponding, or backup.
- Retain any documentation related to Environmental Agency Discharge Permits and system commissioning.
Sale or Transfer of Property
When selling a property with a private drainage system, the seller is legally obligated to inform the buyer of the system’s location, condition, and whether it adheres to the General Binding Rules. Pre-purchase surveys conducted at this stage provide peace of mind and legal clarity for all parties involved.
