Who Lives in the Little Green Houses?

No one, we hope!  If you drive throughout Poplarville, you'll see several of these unusual structures. They are fiberglass, wastewater pump station buildings.  Inside, are two pumps with an electrical control panel.

Under the buildings are large concrete vaults, called "wet wells".  Wastewater flows from nearby gravity collection lines and dumps into the wet wells.  As the level in the wet well rises, pumps turn on and wastewater is pumped to an upstream manhole, and eventually flows to the wastewater treatment plant.

Crushed limestone - good stuff...

Street excavation means repairs are being made, and that's progress.  But don't you cringe thinking about the mess that will be left behind? You know what's coming:  For weeks, you're forced to navigate over or around the big red, muddy speed bump. Your front end gets knocked around. Grandpa's dentures fall out. The baby starts crying. Mommy's minivan needs a wash. And if you're lucky things get patched in a week or two, but usually relief takes a month or longer.  Wretched stuff.

A better alternative...

Our repair subcontractors are required to place crushed limestone topping over all sewer related street repairs. This policy was formulated with the advice of our operator and engineering consultants. We apply 6-8 inches of crushed limestone.  The fine granules allow for packing and firming, and give a relatively mess-free driving surface until settling takes place and asphalt repairs are completed. Crushed limestone is relatively inexpensive, minimizes long-term settling, and provides an excellent base for asphalt patch material.

Grinder pump systems - what are they?

A grinder pump system is a combination of electrical control panel, collection tank, grinder pump, check valves and effluent piping that carries wastewater from a home or business to a sewer collection system.  Grinder pump systems are often used when there is no access to gravity sewer mains or where there in insufficient vertical fall between a building and the main sewer collection system to allow proper drainage.

Here's how the system works: First, wastewater collects in the large tank basin. When the level rises above a set-point which is typically at the half-way point, the electrical control panel activates the grinder pump, which grinds the liquids and solids into a slurry and pumps the slurry out through the check valves and effluent piping. Grinder pump systems are reliable as long as customers are careful to avoid flushing prohibited items which could clog the pump.

Low pressure sewer systems are a collection of grinder pumps installed throughout an entire neighborhood or subdivision. A good example of this is the ongoing project at Hide-A-Way Lake. Low pressure sewer systems are often used where gravity sewer collection systems are neither practical nor feasible, or too costly to install. In addition to lower cost of installation, another advantage of low pressure sewer systems is the minimization of storm-water infiltration and intrusion, which reduces loading at the wastewater treatment.

Sewer Laterals: Who is Responsible?

We receive almost daily service calls concerning sewer backup problems.  Most customers assume that any backup in their home is related to problems with the Utility Authority's main lines.  But most customer backup problems are caused by blockages in the customer's private sewer lateral.  A sewer lateral is defined as the length of pipe running from the customer's home, through their private property, which eventually connects to the Utility Authority's main collection lines.

When we receive a call-out to investigate a customer reported backup, we dispatch operating technicians to verify main sewer lines and roadside clean-out inspection clean-outs, when available, are clear.  If inspection points are clear, the customer is advised to contact a reputable plumbing contractor with appropriate line-clearing equipment to clear their private sewer lateral.  It is our recommendation that plumbers run mechanical line clearing equipment completely to the sewer main lines, usually located under city streets, or backyard alley-ways.

Common causes of blockage in sewer laterals include root intrusion, grease buildup, pipe deterioration, or excess accumulation of paper products.



Launching a New Website...

While the Utility Authority has owned a website since it's inception, it was rarely updated because it required help from a third party, at considerable expense.  

After discussions with our information technology consultant, we were convinced that owning, maintaining, and modifying a dynamic website was do-able, with low investments of time and money.

What better way to share information with our customers?  Check out some pictures of the ongoing CDBG construction projects.  Need to report a sewer backup? We hope not, but if you do, fill out our online service request form. Looking for Utility Authority news? There's a link for that, too. And you've already found the manager's blog, where you'll see what's on our mind.

All choices are listed down the left side navigation bar. We'll be adding more pages in coming weeks.  Until then, drop us a line if you have any questions or recommendations at
