The Importance of Drain Benching

1. Preventing Waste Build-Up:

• Manhole benching refers to the sand and cement haunching between manhole walls and channel pipes.
• It serves two critical purposes:
  • Stopping Rats: Benchings prevent rats from leaving the drainage system or nesting inside them.
  • Splashing Prevention: Incoming branch lines can cause waste and water to splash within the manhole. Without benching, this splashing can lead to waste build up and potentially cause blockages.

2. How It Works:

• Benching creates a well-defined path for wastewater to flow, ensuring that any overspill slides back into the drain channel and continues its journey.
• Benching minimizes the risk of waste build up and maintains effective drainage.

3. Repair and Maintenance:

• Defective benching can lead to erosion, water loss, tree root ingress and subsidence to the grounds around the drain chamber
• If repairs are needed, consider breaking out and reinstalling the benching for a complete, sealed chamber base. Alternatively, patching any defective sections to maintain functionality.

Remember, well-designed benching keeps our drainage systems flowing smoothly and prevents costly issues!

The Importance of Drain Benching: Preventing Rats and Waste Accumulation

1. Why Drain Benching Matters

Drains play a vital role in our homes and communities, ensuring efficient wastewater flow. However, without proper maintenance, drains can become breeding grounds for problems like clogs, waste buildup, and even rat infestations. Here’s why drain benching is crucial:

a. Rat Prevention & NRVs (Non Return Valves)

• Rat – are, opportunistic creatures and can infiltrate our properties through various entry points, including drains. They travel through sewers and up pipes, eventually finding their way into our homes and businesses. The use of good benching and NRVs can help prevent rodent ingress.
• NRVs act as a door that allows waste to exit but prevents anything including rodents from entering. NRVs for this purpose are usually of a metal construction preventing rodents chewing through them.
• Drain benching acts as a barrier, preventing rats from leaving the drainage system or setting up camp and nesting. By sealing gaps and creating a well-defined path with Hunching to make life as difficult and uncomfortable as possible for them, it keeps these unwelcome guests in check.

b. Splashing Prevention

• Incoming branch lines can cause waste and water to splash within manholes. Without proper benching, this splashing leads to waste accumulation, which can ultimately result in blockages.
• Properly designed benching ensures that waste flows smoothly and doesn’t linger, reducing the risk of blocked drains and backups.

2. How to Make Your Property Rat-Unfriendly

To keep rats away, consider the following steps:

Seal Entry Points

• Roofs: Repair any broken roof tiles promptly and use wire mesh to seal gaps.
• Entrances: Seal gaps under doorways and fit strips to prevent rat access.
• Exterior Walls: Fill holes or small openings in exterior walls up to a height of around four feet using wire wool, caulking, or concrete.

3. Protecting Your Drains in Uckfield and Mid Sussex

Your property is now safe from rats except for one vulnerable point: your drains. Here’s how to protect them:

a. Sealed Drainage

• Ensure there are no openings between your property’s drainage pipework and the sewer. Regular access covers allow inspection and maintenance from the surface.

b. Additional Measures

• Depending on the type of drain, consider additional measures:
  • Rodent Mesh: Install rodent mesh to prevent rat entry.
  • Plugging Disused Pipes: Seal off unused pipes.
  • One-Way Valves: These allow water and waste to flow out to the sewers but prevent rats from returning up the drain pipes into your property.

Remember, a well-maintained drainage system keeps both rats and waste at bay, ensuring a cleaner, healthier environment for all!
